2020 Corvette Stingray is the Official Pace Car of the 104th Indianapolis 500

2020 Corvette Stingray is the Official Pace Car of the 104th Indianapolis 500


We’ve been expecting to hear this news and finally today it has been confirmed by Chevrolet that the new 2020 Corvette Stingray will be the official Pace Car of the 104th Indianapolis 500. This marks the 17th race that Corvette has served as the official Pace Car, and the 31st Chevrolet to lead the field.

This year’s running of the Indy 500 will take place on Sunday, August 23 with the race being shown live on NBC.

With no fans allowed in attendance this year due to the COVID-19 pandemic, the official pace car driver will be GM President Mark Reuss.

“It’s truly an honor to have the opportunity to be behind the wheel of the mid-engine Corvette Pace Car at such a historic race as the Indy 500,” said GM President Mark Reuss. “The 2020 Corvette Stingray is the result of a close collaboration between the Corvette Racing and production engineering teams, setting a new benchmark for supercars around the world.”


The 2020 Corvette Stingray Pace Car is Torch Red and features the high Wing Spoiler and ground effects package. The Z51 Coupe will also wear the 104th Indy 500 livery on the doors. The new 2020 Stingray is capable of accelerating from 0-60 in 2.9 seconds and has a top speed of 194 mph, so it should have no trouble in setting the pace for the IndyCar racers.

“This is a continuation of our outstanding partnership with Chevrolet,” Indianapolis Motor Speedway President J. Douglas Boles said. “We’re so grateful for all that Chevrolet has contributed to the success of our events. The Torch Red 2020 Corvette Stingray is a world-class machine rich with speed, performance and excitement, perfectly suited to pace the ‘500′ field.”

Chevrolet has been linked to the Indianapolis Motor Speedway with both entities founded in 1911. Company founder and namesake Louis Chevrolet and his brothers Arthur and Gaston raced in the early 500-mile races with Gaston winning the race in 1920. Today, Louis Chevrolet rests in peace in a local Indianapolis cemetery just 15 minutes away from the track.

Everything You’ve Ever Wanted To Know About Hot Wheels (But Never Asked)

Many gearheads have a strange affinity to Hot Wheels. Here is everything you’ve ever wanted to know about the company, but never asked.

Toy cars can be divided into two categories: Hot Wheels and everybody else. For over 50 years, Mattel has dominated with what is now recognized as the best-selling toy in the world. It’s impossible to count how many car buffs, from mechanics to real race stars to TV personalities, grew up playing with these cars. Whether it was just a few models or massive collections, Hot Wheels has been part of car culture for decades and is never going to stop. Whether it’s a simple model or some fancy licensed vehicle, Hot Wheels simply enthralls.

Yet it’s incredible how some people are unaware of the facts of the company and its history. From its unique origins to how these cars are put together, the story behind Hot Wheels is fascinating. There are also touches from how some of these cars are more expensive than real ones to some unique touches on the culture. Here are 20 amazing facts about Hot Wheels to prove they’re more than just “kids toys.”‘

20/20 Real-Life Hot Wheels Jump Was A World Record

Growing up a massive Hot Wheels fan, racer Tanner Foust decided to honor them in a fun way. At the 2011 Indy 500, Foust talked the management into seeing up a massive orange ramp and raced down it in a rally car.

After 90 feet of track, Foust sailed 332 feet, the longest record for such a move. He topped it by driving through a 66-foot loop in 2012 to live out the dreams of every kid.

19 Technology In Car Building Is Amazing…

Making toys has become a very high-tech business today. Just like real car companies, Hot Wheels has adapted to the 21st century nicely. Computers and 3-D technology are utilized to make sure the designs are perfected before the building begins.

It also helps them keep on top of the latest car trends to ensure that today’s Hot Wheels are sleeker and more natural than the ones of the past.

18 But They’re Still Diecast

There are many toy car lines out there, but Hot Wheels is still the king of the bunch. The key reason is that, for all the advances in technology, every car is still diecast and built mostly by hand.

Even when cheaper materials are available, Mattel knows the diecast is what the fans want. It’s also helped in making customized cars at home for popular models. After 50 years, Mattel doesn’t want to mess with success and do away with diecast.

17 They’ve Worked With NASA

Hot Wheels have done a few astronaut-themed toys over the years. But that’s not the only connection they have with NASA. In 1998, they were able to work with the agency to create an exact replica of the Mars Rover, which landed on the Red Planet that very year.

They also worked with them in 2012 for scale models of the Curiosity rover. It’s amazing how the company got access to top-secret plans to make these toys.

16 Collectors Take It Seriously

Some may dismiss Hot Wheels as “just for kids.” But collectors take it more seriously than real automobiles. The 1969 Volkswagen Beach Bomb (only 16 prototypes were made) is known to go for at least $15,000.

Some rare models can go for a hundred grand, and collectors are always on the lookout for unique mint models. Entire museums are devoted to various cars as some Hot Wheels collections put legit car collectors to shame.

15 Scaling Down The Cars Was Tricky

A key to the company’s success is that they work with scores of real car companies to get looks at plans for their toy models. Yet it’s not so simple as just “make a smaller version.” The biggest challenge is to achieve the proper scale for the toys in a diecast model yet retain the details of the actual car.

That can be complex with some fancy vehicles. That every model has to be sized to fit the same tracks just adds to why it takes as long developing a toy car as a real one.

14 NASCAR Star Has The Record For The Longest Track

Ever since the Hot Wheels tracks were created, fans have been trying to top themselves making the most extended and most complex. A few have achieved great ones, but it’s fitting a NASCAR star holds the record for the longest.

In 2019, Joey Logano unveiled a 1,941-foot long track stretched across his garage. It weaves through his car collection with 1222 boosters before ending in Logano’s own 2018 HW Ford Mustang. Add yet another title to Logano’s list of accolades.

13 They Made A Car Coated In Diamonds

In 2008, Mattel made a big deal of celebrating the 40th anniversary of the Hot Wheels line. As a special reward, Mattel had Jasons of Beverly Hills craft the most expensive Hot Wheels car on the planet.

Cast in 18-karat gold, it’s covered with 2700 diamonds and gems totaling nearly $150,000 today. It’s become a rotating exhibit at toy museums for the glitziest Hot Wheels you could see.

12 The Darth Car Is A Speed Machine

While they do stick to toys, the company has been busy creating some real-sized cars for collectors. One of the most notable is based on Darth Vader, with the hood looking like his fearsome helmet and in jet black.

This isn’t just for show as it’s based on a C5 Corvette with a GM LS3 V-8 engine capable of 526 hp and 150 mph. The Dark Lord of the Sith would be proud of this powerful craft.

11 Every Car Is Tested To Make Sure It Can Run A Track

Almost from the beginning, Hot Wheels car fans had to have a track with the cars. They’ve gone from straight lines to elaborate roller-coaster-like loop systems to leave kids entertained for hours.

What few realize is that the track determines if a car makes it as Mattel prides itself on “every car can fit every track.” More than once, a prototype has to be altered when it won’t fit as the track decides a car’s final form.

10 There Are More Hot Wheels Cars Than Real Cars

While it’s tricky to figure out for sure, most sources agree there are at least one billion cars on the planet (give or take a few hundred thousand in auto graveyards). In contrast, since 1968, six billion Hot Wheels cars have been created.

True, many have been trashed and/or recycled, and it’s impossible to count how many have been lost in backyards. But given how 16 cars are produced every second, it’s no shock the toys outnumber the real deals.

9 Several Creators Are Legit Car Designers

The one constant of Hot Wheels is that the cars look just as good as the real deal. There’s an excellent reason for that as scores of the manufacturers are legitimate car designers. Larry Wood was a veteran of Ford before becoming one of the first Hot Wheels designers.

He’s not alone as Jack Ryan was a rocket designer who crafted the bearings that made the cars so great. Scores of the car designers were in real automobiles first, so it’s no wonder the vehicles look so good.

8 The Original Camaro Is Worth A Fortune

Mint conditions of the Original 16 Hot Wheels releases are all pretty collectible items. But one dominates from the pack. While versions of a Camaro were produced, a few had white enamel paint.

They had been meant to discover flaws in a prototype but accidentally released. A mint version of one went for a hundred thousand dollars and made this one of the most expensive toys on the planet

7 They Released A Custom Corvette Before GM Did

An early standout for the company at a custom Corvette in 1968. What made it notable was that the toy was released before GM had their actual Corvette in car dealerships.

The fact designer Harry Bradley had worked at GM indicates he may have “borrowed” the designs before he left to allow Mattel to beat GM to releasing a Corvette to the masses.

6 The Red Stripes Are Expensive

If you find what looks like an old Hot Wheels car, take a good look at the wheels. If they have red stripes, then you’ve just found a fantastic collector’s item. From 1968 to 1977, designers hand-painted red lines onto the wheels to make the cars look distinctive.

As a cost-cutting measure, they switched to all-black wheels in 1978. Some mint condition red-striped vehicles have been known to go for thousands online.

5 One Of The Original Cars Was Based On A Car With No Doors

The first wave of Hot Wheels was just 16 cars, and any of them can be valuable today. One is notable, the 1965 Dodge Deora. This car boasted no doors but rather a hatch for folks to crawl into.

It was based on a fun design used by Mike and Larry Alexander but in an irony, no real Dodge Deoras were built, to make this a truly unique model

4 A Tie-In Cartoon Got Pulled By The FCC

Today, cartoons based on toy lines are commonplace. But in 1969, Hot Wheels got in trouble when they put out a cartoon series about some teenage car drivers. Despite good messages, the show was hit by complaints about being a “half-hour commercial.”

The FCC agreed, and it was yanked off the air. The company was just ahead of their time with a cartoon tie-in for a hit toy line.

3 There’s A Fight On Where The Name Came From

Much of Hot Wheels is shrouded in myth, and that includes just where the name comes from. The familiar story is that when Eliot Handler saw the first models from designer Fred Adickes, he remarked: “those are some hot wheels you’ve got there.”

Another version is that Handler just blurted the name out in a meeting with a designer. Regardless, it just stuck to become one of the most popular toys on the planet.

2 They’re Number One…Because They Remain So Cheap

In the ranks of the most popular toys on the planet, Hot Wheels dominates. They’re not just the biggest toy vehicle sellers but also the number one selling toy in the entire world. The reason is that in many markets, the cars can still go for only a dollar each.

True, they can be put out in packs, and some nations charging a few bucks more. But many stores do sell the cars for less than a bottle of water, which is the reason they are so dominant.

1 Its Creator Was Married To Barbie’s Creator

Elliott and Ruth Handler were the First Couple of the toy world. The two had founded Mattel as a picture frame company in 1945. While making a dollhouse, Ruth decided to craft a series of dolls she named Barbie.

It was an instant hit to make Mattel a success. Elliott then realized how a toy car line could be great for boys to craft what would become Hot Wheels. The two remained together until Ruth’s death in 2002 (Elliott passed on nine years later) to be icons of their industry.

Watch a Track-Day Comparison Between the Shelby GT500 and C8 Corvette

Both cars retail for about $81,000, but one is a lot more accessible.

SPEED PHENOM ON YOUTUBE

If you’ve got $80,000 to spend and want an American high-performance car, now’s a pretty good time to be in the market. In addition to tire-shredding stalwarts like the Camaro ZL1 and Challenger Hellcat, Ford and Chevy have recently launched high-profile, track-ready sports cars. And thanks to a new video by Speed Phenom, we now know how they directly compare on track.

Naturally, we wanted to do this comparison ourselves. But the GT500 wasn’t ready during our Performance Car of the Year competition when we had an early C8 to test. And now that both cars are on sale, stay-at-home orders and track closures mean we’ll have to wait for an opportunity to do a full R&T comparison.

In the meantime, Speed Phenom does a good job of breaking down how they perform. With the caveat that he’s got a base model GT500 without the optional Pilot Sport Cup 2 tires, he notes that the car struggles for grip more often than the similarly-tired Corvette. It’s also less composed through mid-corner bumps, with slower cornering all around. Thanks to its massive horsepower advantage, though, it jets through straightaways.

The C8, meanwhile, benefits from serious mechanical grip. The better-balanced midship car fires through corners and has no problem putting its power down. That makes it more approachable, not surprising given that it’s the tamest version of the C8 while the GT500 is stretching the limits of the S550 platform. We’re sure to see more track-ready Corvettes soon, but for now the Stingray is a surprisingly capable start.

Watch a C8 Mid-Engine Corvette Hit 173 MPH on a Dry Lake Bed

Even off the pavement, the new ‘Vette is a rocket ship.

The 2020 C8 Chevy Corvette is a fast car. In base form, it can hit a staggering 194 mph flat-out. Even with the drag-inducing Z51 performance package, the car can still do 184. Hennessey Performance took theirs to 182 mph with ease before they turbocharged it to oblivion. Now, there’s another C8 top-speed run on the internet, and this time, it takes place on a dry lake bed.

Popular YouTube TheStradman took his new Z51-equipped Corvette to a dry lake bed in Utah to test out the top speed of the car. He managed to hit an impressive 173 mph before slowing down—not bad considering the uneven and bumpy surface. It helps that there’s absolutely nothing for miles in either direction. In fact, from inside the cabin, it looks a bit uneventful. Here’s a perspective from outside the car to give you a sense of how fast 173 mph is:

If the base Corvette is this quick right out of the box, we’re curious to see how the upcoming Z06 stacks up. Considering the last-gen car could hit 200 mph, we’re expecting big things.

Mid-Engined Chevy Corvette Video Analyses The 2LT Interior

The Goldilocks zone of Corvette C8 interiors?

By now, you should know that Chevrolet has started deliveries of the mid-engine 2020 Corvette. Lucky owners of the ‘Vette C8 are starting to receive their newest toy and most likely you’ve already seen one on the streets – that’s if the state you’re in is not affected by the coronavirus lockdown.

If you’re among those who are planning to purchase the new Corvette but are undecided with the trim level to choose, this video might be able to help you – especially if you’re particular with a car’s interior.

The Corvette C8 comes with three trim levels: 1LT, 2LT, and 3LT. The differences lie mainly in the features offered on each trim level, which defines that the cabin will look and feel like. That’s pretty important, considering that we spend so much time inside the car rather than staring at our investment from a distance. So, here’s a little guide.

The base 1LT trim isn’t really basic. With the entry-level trim, you already get the GT1 seats wrapped in mulan leather, a customizable 12-inch gauge cluster, push-button ignition and keyless entry, and an 8-inch Chevy MyLink infotainment system with Apple CarPlay and Android Auto, 4G LTE Wi-Fi, and 10-speaker Bose sound system. The Corvette 1LT trim is available in three color options: black, gray, or red.

Going up the 2LT trim gives you more interior color options plus features like a rearview camera mirror, a colored head-up display, heated/cooled seats, heated steering wheel, advanced blind-spot monitor, and rear cross-traffic warning. The infotainment gets upgraded as well with a wireless charger and a 14-speaker Boss audio system.

Finally, the 3LT trim dials up the ante by adding a premium Nappa leather with suede microfiber accents – all in combination with the GT2 seats that have more bolsters. These seem not a lot but the range-topping trim adds luxury to the sports coupe.

If you’re still undecided, watch the 2LT interior review on top of this page to check whether you need to take it down a notch to 1LT or go all out on the top-level 3LT.

Hennessey’s twin-turbo C8 Chevy Corvette V-8 makes 643 horsepower early in development

It took 30 hours for Hennessey Performance Engineering to tear apart a new 2020 Chevrolet Corvette, install twin-turbo setup, and put it back together.

It’s no surprise, then, that the twin-turbo C8 Corvette isn’t ready to be sold to customers. The engine lacks intercoolers and Hennessey hasn’t cracked the code of GM’s new electrical architecture to reprogram the ECU.

“This is just the beginning, our own car, doing R&D,” company founder and CEO John Hennessey told Motor Authority.

On Monday, the engine made 643 horsepower and 570 pound-feet of torque at the wheels on a Dynojet dyno while running just 5 psi of boost. That compares to baseline testing HPE performed on the stock car which revealed 466 hp and 451 lb-ft of torque. HPE plans to offer a 1,200-hp version of the C8, which Hennessey said could make 18-20 psi of boost.

Hennessey took delivery of an orange C8 Corvette in Detroit on March 13. He and his daughter, Emma, drove back to the performance outfitter’s Texas headquarters and performed baseline testing before the Hennessey team tore apart the car.

The orange C8 fired back to life on Friday with twin 62-mm Precision Turbos and twin blow-off valves connected to the throttle body mounted behind the catalytic converters. Both turbos are oil-cooled with twin scavenge pumps that feed back into the motor.

The system is not intercooled. Instead, there’s a methanol injection setup to keep things from getting too hot. HPE is considering where to put intercoolers. The current packaging has limited space for intercoolers without cutting into trunk space, which Hennessey does not want to do. 2020 Chevrolet Corvette Stingray undergoes twin-turbo conversion at Hennessey

Hennessey told Motor Authority his team currently can’t tune the factory ECU, but it is looking at aftermarket solutions for the engine management system. He noted it took a year for solutions to come to market for the C7 and added, “hopefully, it won’t take a year.”

Hennessey said when the turbocharged C8 was first started it didn’t throw any codes, errors, or a check engine light. “The computer seems happy with the turbos,” Hennessey noted. A check engine light did appear when the front wheel speed sensors were disconnected to put the car on the dyno, Hennessey said.

The orange C8 will used for R&D of upcoming modifications. Hennessey said he doesn’t expect to deliver modified customer C8s for at least six months, and all will have intercoolers and full plumbing.

2020 Chevrolet Corvette vs. 2020 Ford Mustang Shelby GT500 at the Drag Strip

Did you see the two race on YouTube? We’ve tested them, too; here’s why the results were no surprise.

image
  • We have tested both the 2020 Chevrolet Corvette (11.2 seconds at 122 mph) and the 2020 Ford Mustang Shelby GT500 (11.4 seconds at 132 mph) in the quarter-mile.
  • A video on YouTube, however, shows flipped results: 11.5 seconds at 120 mph for the Corvette and 10.8 seconds at 132 mph for the GT500.
  • As always, the driver and track conditions are critical, and our two-run average is far more repeatable than any one-off run at a drag strip.

When we tested Ford’s new 2020 Mustang Shelby GT500 against the top-dog 2020 Chevrolet Camaro ZL1 1LE, the Mustang came out on top on the drag strip. But how does the front-engine Shelby stack up against the other, now mid-engine, threat from Chevy?

Greg PajoCar and Driver

During our testing, the GT500 hurtled through the quarter-mile in 11.4 seconds at 132 mph. But that was on a regular street-like surface, not a sticky, prepped drag strip. We struggled mightily with traction at launch, and our best run was with the launch control set to the lowest rpm allowed (1200 rpm) to prevent igniting a rear-tire fire. However, no surprise: with more traction far, better numbers are possible, and we’ve seen numbers below 11 seconds at drag strips, including this kid, who ran a 10.665 shortly after he acquired the car.’Murica Which Ultimate Pony Car Is the 1/4-Mile King?This Kid Ran a 10.66 Quarter Mile In His GT500

On the other hand, the 2020 Corvette has far fewer launch struggles, as it benefits from its newly acquired mid-engine layout and rear weight bias. Moving the weight distribution rearward improves launch traction, helping it jump off the line much quicker. During our testing, and despite far less horsepower, the mid-engine Vette outaccelerated the GT500 through the quarter-mile by two tenths of a second, reaching it in 11.2 seconds at 122 mph.Advertisement – Continue Reading Below

We’re starting to see other people’s numbers from both of these cars, though, as customers are starting to take deliveries of their C8 Corvettes and GT500s. Contrary to our test results, there’s a video circulating on YouTube that shows the new GT500 beating the C8 Corvette through the quarter-mile by seven-tenths of a second. It raced to the quarter-mile in 10.8 seconds while the Corvette reached it in 11.5 seconds.

Keep in mind that the driver and conditions are huge factors in quarter-mile and acceleration results. We suspect that here, the Corvette likely got bogged down on the high-grip surface, as the launch control isn’t optimized for those conditions, and the 760-hp Mustang benefited from the extra traction on the track.

The Corvette’s Hybrid Future Is Hiding in Plain Sight

Chevrolet has kept quiet about whether an electrified midengine Corvette is in the works, but the owners manual apparently didn’t get the memo.

OK, so “plain sight” might be a bit of an overstatement, but further evidence that a hybrid midengine Chevrolet Corvette is in the cards is right there—if you know where to look. And in this case, you have to look at page 244 of the 2020 Corvette owners manual. You can download your very own copy in PDF form right here if you so desire.

As the wonderful Chevy nerds at Corvette Blogger (who brought this tidbit to our attention) explain, it all has to do with fuses, or at least designated spaces on the Corvette’s rear compartment fuse block.Related Story20 Coupes You Can Buy Instead of the C8 Corvette

First up is fuse No. 7, “Power sounder module/Pedestrian friendly alert function.” That’s a fancy term for the noise electrified cars must make when they are not running on internal combustion power (if they even have an IC engine onboard) in order to keep the people around them aware of their presence. Usually this sound is some sort of vaguely futuristic whir, whine or murmur.

Then, there’s fuse No. 12, which works in conjunction with a “Lithium ion battery module.”

The owners manual information for the 2020 Chevrolet Corvette’s rear fuse block. Pay special attention to slots 7 and 12.CHEVROLET

The latter implies a hybrid system, and the former isn’t necessary on any vehicle that isn’t capable of running, for at least a short distance, on electric power. Neither of these things are true about the 2020 Corvette, though they’d be necessary in the rumored Corvette hybrid. And it would make sense that, if such a car were planned, Chevrolet would build a certain amount of infrastructure for hybrid systems into the car from the very beginning—especially when you’re dealing with something as fundamental as a fuse block.

(For the record, we looked through owners manuals for other new Chevrolet vehicles, including the Blazer; there’s no fuse block openings for these systems, implying that they aren’t something GM simply includes by default as a sort of “just in case” contingency.)Related StoryThe New Midengine Corvette Is a Blast to Drive

This is hardly the first time we’ve speculated about a hybrid Corvette. Such a car would likely place a motor up front (there’s room for one ahead of the front bulkhead, right in between the two front wheels) and tuck batteries away in the center of the car, probably nice and low in a tunnel between the two seats, in order to maintain a low center of gravity and balanced front-rear weight distribution. What remains unknown is what gasoline engine such a system would complement.

A hybrid Corvette could stick with the regular car’s 6.2-liter naturally aspirated LT2 V8, but video suggests that a flat-plane crank V8 appears to be in the works, as well. Giving either of those engines an extra 100-plus hp and all-wheel drive by adding an electric motor to the mix would turn an affordable supercar into an all-American exotic.

In any case, it’s clear that this is just the beginning for the midengine Corvette—and that speculation on what’s next hasn’t died down even after the model’s debut.

Tech We Would Like to See on the C8 Corvette: Active Aero

Tech We Would Like to See on the C8 Corvette: Active Aero


With the highest performance versions of the seventh generation Corvette, customers were forced to make a choice. Did they want their car to have the highest possible top speed, or did they want to sacrifice some of that by bolting a slew of aerodynamic aids to their car for maximum cornering ability?

We would love for Chevrolet to take that decision out of the ordering equation for buyers of the upcoming Z models and the Grand Sport. They could give buyers the best of both worlds with the incorporation of Active Aerodynamics.

Active Aerodynamics can take many forms, from grille vents that close at high speeds to streamline a car, to suspension that lowers at speed to reduce lift. We know that the Corvette team would build a fully functional system that integrates several of these technologies into a cohesive package, just like they did on the C7 ZR1’s chassis-mounted wing and innovative balancing front underwing, but what we mostly want to focus on here is the most visible piece of such a system, the rear wing.

This unit would elevate both the performance and even the prestige of GM’s looming halo car. There are several benefits of an active rear wing that accompany their off-the-charts cool factor.

1. An active rear wing can be lowered, causing it, for all intents and purposes, to disappear, along with any drag that it was creating. Top-end General Motors Products have become so fast that the most track-worthy editions have suffered at the dragstrip because of massive fixed wings. The effects of the C7 Z06/Z07’s wickerbill spoiler have been well documented. Chevrolet officially listed the top speed of ZR1’s with the “big-wing” ZTK package as 10 MPH lower than their stock counterparts, and the Camaro ZL1 with the 1LE package has proven slower than the car it is based on, even in distances as short as a quarter-mile. Allowing these serious track performers to retract their wing, and the ZTK/Z07/1LE models become the best version of their respective model-line with no excuses or asterisks, which is what buyers that dole out more funds expect.

2. Just as these wings can retract to reduce drag and improve top speed, they can be “actively” placed in full “attack mode” for maximum downforce in the corners. This increases cornering speed, stability, and driver confidence which can lead to drastically lower lap times.

3. Upon hard braking, an active wing can also go vertical, transforming into an air brake. This assists the actual brakes, resulting in shorter stopping distances. It also keeps more weight in the rear of the car, again helping with stability and, especially in a rear-wheel drive car, improved corner exit speeds.

All three of these traits brought to the table by an active wing radically assist the driver and make the car faster in all aspects. The coolest thing is that, with the right programming, the wing does all three automatically with seamless transitions, and, did we mention how awesome they also look?

There has been speculation about Active Aero coming to the Corvette for several years now. These rumors were fueled by GM’s own patent filings which showed a sketch of a C7 fitted with advanced aerodynamic trickery. We think the top dog mid-engine offerings are the perfect place for the General to finally deploy this technology that can already be found on the majority of the world’s supercars.

Rare drawings, documents reveal secret history of mid engine Corvette

From an acclaimed concept car John DeLorean reportedly dismissed because he wanted something “smaller and more European,” to the design that ended a feud between a pair of GM giants — but may have set the Corvette back decades — a trove of unique documents, sketches and models tells a secret history of the 60-year quest to build a mid engine Chevrolet Corvette.

The story begins in the late 1950s with legendary Corvette chief engineer Zora Arkus-Duntov and came to fruition when the first mid engine 2020 Corvette Stingray sold for $3 million at auction in January.

Titled “The Vision Realized: 60 Years of Mid engine Corvette Design” and created by GM Design Archive & Collections, the exhibit included 19 original sketches by designers including Larry Shinoda and Tom Peters, the massive 4-Rotor rotary engine from the 1973 Aerovette engineering, a wood wind-tunnel model, even letters from Arkus-Duntov’s personal files.

“The story of the mid engine Corvette is incredibly complicated, full of fits and starts,” said Christo Datini, manager of the GM Design Archive & Collections.  Cristo Datini at the General Motors Warren Technical Center in Warren, Michigan on Friday, January, 31, 2020

A mid engine Corvette was a dream shared by GM designers and engineers. The layout, in which the engine is behind the passenger compartment and immediately over the rear wheels, improves acceleration and handling. It’s been a mainstay at Ferrari for decades, and inspired repeated design and engineering projects at GM. None of them made it to production till now, largely because the Corvette’s original front-engine layout was so successful.

“Why would we change the Corvette?” GM chairman and CEO Richard Gerstenberg said to Arkus-Duntov before both men retired in the mid-1970s. “We sell every one we can make.”

‘Design without limit’

A generation of GM designers and engineers had already fought that attitude toward the sports car that debuted in 1953 model, and a couple more would before the midengine eighth-generation C8 Corvette Stingray debuted last year.

The exhibition included dozens of sketches, models, photos and documents.

“Our mission is to preserve the heritage of GM Design and educate our designers on GM’s prominence in the world of design,” Datini said. The archive also is working with the Detroit Institute of Arts on a massive exhibition dedicated to automotive design that opens this summer. 

The Corvette exhibition closed at the end of January, but elements of it are likely to be displayed at other events and locations, possibly including the National Corvette Museum in Bowling Green, Kentucky, which provided materials for the collection.Original magazines with drawings of what Corvettes could have looked like on display at the General Motors Warren Technical Center in Warren, Michigan on Friday, January, 31, 2020

Chevrolet Engineering Research Vehicle I, Also called SERV I and XP-708, was the beginning. A running model that debuted in 1960, the car had the looks of an Indy car and a chassis that tested what a midengine layout could do. It was “a design without limit” and an “admirable tool” to help Chevy figure out “what to put in Corvette,” said Duntov, himself a former driver in the 24 Hours of Le Mans sports car race.

CERV I was used as a test vehicle for years. Larry Shinoda, who would go on to be known as the father of the ’63 Corvette Stingray and the Mako Shark concept car, tweaked its design repeatedly as engineers tested it with seven different power trains.

GM eventually retired CERV I, selling it to the Briggs Cunningham Automotive Museum for $1. When the museum failed in the 1980s, GM bought it back for “somewhat more,” Datini said.A model of the 1968 Chevrolet mid-engine Corvette Roadster that is one of many items for General Motors workers to see at the Corvette design display at the General Motors Warren Technical Center in Warren, Michigan on Friday, January, 31, 2020

Corvettes the world never saw

Shortly thereafter, Duntov heard rumors Ford was developing a Le Mans racer to challenge Ferrari and launched work on CERV II. GM decided not to race, Ford and Carroll Shelby built the GT40 that inspired “Ford vs. Ferrari,” and the CERV II was used as an engineering test bed at secret proving grounds and never seen by the public during its active lifetime. Built in 1964, CERV II had a 500-horsepower V8, 210-mph top speed and 2.8-second 0-60 mph time.

“By that time, engineers and designers knew a midengine chassis was necessary” to get maximum performance from the ‘Vette, Datini said. Putting the engine behind the passenger compartment puts the car’s weight over the rear wheels to put down more power without spinning. Shifting balance from the production ‘Vette’s nose-heavy weight distribution would also improve handling.

Also in 1964, the XP-819 experimental car was being tested. Designed by Shinoda, it bore a strong resemblance to 1970 Corvettes, but Duntov hated it, calling it an “ugly duckling” at least in part because he wished his engineering team got some of the budget allotted to designing the car. It had a 327 cubic-inch V8 and pop-up headlights.

Like many concept and engineering vehicles, XP-819 was destroyed, chopped up. Years later, the pieces were found in NASCAR designer and mechanic Smokey Yunick’s garage.

Half Corvette, half Porsche

With a name GM would later recycle on a minivan, the Astro II XP-880 was never publicly identified as a Corvette, but it was one, intended for production in 1970, but never got there. It debuted at the New York auto show, featuring a nose, front fenders and Firefrost Blue paint that that foreshadowed 1970s production cars.

DeLorean, then Chevrolet general manager, asked for a rush program to create a different midengine design to match the midengine Pantera Ford was developing with Italian sports car maker De Tomaso to debut at the 1970 New York auto show. The XP-882 had a tapering body with dramatic fender flares and a louvered rear window like the Mako Shark II concept car. Like so many midengine ‘Vettes before and after, GM brass decided to stick with the tried and true front-engine layout.

Also in the 1970s GM president Ed Cole — another legendary engineer who led the development of the small block V8 and catalytic converter, among other achievements — became enamored with the Wankel rotary engine. Duntov built two midengine experimental ‘Vettes with rotary engines, glad for Cole’s support despite not sharing his enthusiasm for the engine.Sketching and notes about the Corvette, one of the many originals on display for workers to see at the General Motors Warren Technical Center in Warren, Michigan on Friday, January, 31, 2020

The 1973 Corvette 2-Rotor XP-987GT was a smaller, European-scale sports car with a rotary engine. The body was all Corvette, but its chassis came from a Porsche 914. Italian design house Pininfarina built its body. GM displayed the 2-Rotor at auto shows in Frankfurt and Paris before the car disappeared, probably sold to a collector.

Bill Mitchell’s most beautiful car

At the same time, Duntov wanted to develop a bigger midengine Corvette. He and Cole hadn’t been on speaking terms since Duntov refused an annual bonus he thought was insultingly small. They made up, at least in part because Duntov wanted a budget to develop what would become the Corvette 4-Rotor Aerovette, an iconic, gull wing design. Duntov believed it was the most beautiful vehicle GM design chief Bill Mitchell oversaw in a career that included the ’57 Chevy Bel Air and ’66 Buick Riviera. 

Duntov recycled the XP-882’s chassis for the Aerovette, which featured silver leather interior trim.A picture of the Aerovette featuring bi-fold gulping doors in the sports car that was never made.

Despite the car’s striking appearance, Duntov would come to believe his agreement to use a rotary engine was a nail in the midengine ‘Vette’s coffin.

Despite that, another midengine engineering car arrived in 1974. The XP-895 began its life with a steel body. Intrigued by the idea of lightweight materials, DeLorean asked Reynolds Aluminum to create an aluminum body. That cut the car’s weight by nearly 40%, but DeLorean pulled the plug on the project because he wanted a smaller, more European design.

That never happened, and design work on midengine ‘Vettes came to a halt for more than a decade, as GM struggled meeting the challenge of higher fuel prices.

Closing the deal

By 1986, the quest for a midengine Corvette was ready to create another giant figure, and it got one when a young designer named Tom Peters began work on the Corvette Indy concept car. Peters went on to become the chief designer of the sixth- and seventh-generation C6 and C7 Corvettes and play a key role in starting work on the 2020 C8.

With a radically short hood compared to production ‘Vettes and cutting-edge technologies including four-wheel steering, traction control and active suspension, the Indy — so named because it used a 2.65L V8 Chevy developed for Indy Car racing —  kept dreams of the midengine ‘Vette alive

The 1990 CERV III — this time the C stood for “Corporate,” not Chevrolet Engineering Research Vehicle — was the next step. Datini’s research convinced him it was an attempt at a production version of the Indy.

CERV III had scissors doors and was built of Kevlar, carbon fiber and aluminum. With a 650-hp twin-turbo 5.7L  V8, GM predicted a top speed of 225 mph. It debuted at the 1990 North American International Auto Show in Detroit.

After that, work on the midengine Corvette went undercover for two decades. Photos of disguised prototypes at test tracks surfaced from time to time, but the car seemed to be as much myth as metal. There are whispers the Great Recession halted work on one, setting development back years.A display of Zora Arkus-Duntov known as "The Godfather of  the Corvette" at the General Motors Warren Technical Center in Warren, Michigan on Friday, January, 31, 2020.

Development of the 2020 Corvette Stingray began around eight years ago, a long time for most projects, but the blink of an eye when it’s the last chapter of a 60-year story.

ROLEX 24 AT DAYTONA – AN IMPRESSIVE DEBUT FOR THE NEW CORVETTE C8.R

The 58th Rolex 24 at Daytona, the first round of the 2020 IMSA WeatherTech SportsCar Championship season, saw the first race for the new Corvette C8.R, the participation of an all-female driver line-up, 2019 NASCAR champion Kyle Busch’s first start in a 24-hour race and Ben Keating at the wheel of two different cars.

A NOTEWORTHY DEBUT FOR THE NEW CORVETTE C8.R

The #3 Corvette C8.R finished the first 24-hour race of its career in fourth place in GTLM (the equivalent of LMGTE Pro at the 24 Hours of Le Mans). Drivers Antonio García, Jordan Taylor and Nicky Catsburg encountered zero problems with the car and completed 785 laps (nearly 5,000 kilometers). Unfortunately, the same cannot be said of the #4 Corvette C8.R of Gavin-Milner-Fässler. As the car was in the top 5 in its class going into the ninth hour, an oil leak caused the car to return to its garage. The leak was found to be in an area that forced the mechanics to remove the engine for repair and the work took almost nine hours. The #4 was then able to hit the track again and finished the race in 36th place.

Much like the 24 Hours of Le Mans, the 24 Hours of Daytona is an extremely challenging race. To make it to the checkered flag with an all-new car is already a major accomplishment for Corvette Racing. The American team’s next stop is the 6 Hours of the Circuit of The Americas on Sunday 23 February in Austin, the fifth round of the 2019-2020 FIA World Endurance Championship season.

AN ALL-FEMALE DRIVER LINE-UP

All-female driver line-up Christina Nielsen, Katherine Legge, Tati Calderon and Rahel Frey shared GEAR Racing powered by GRT Grasser’s Lamborghini Huracan GT3 in the GTD class, but the car was forced to retire after a fire.

KYLE BUSCH ENJOYS HIS FIRST ENDURANCE RACE

2019 NASCAR champion Kyle Busch took the start in his first Rolex 24 at Daytona at the wheel of the AIM VASSER SULLIVAN team’s Lexus RC-F GT3. Along with teammates Parker Chase, Jack Hawksworth and Michael de Quesada, Busch finished 26th overall and ninth in the GTD class. The American driver pulled off a double and a triple stint without the slightest mistake and said after the race he really enjoyed the experience and hopes to return for the overall win.

BEN KEATING DOUBLES DOWN

Ben Keating participated in his 10th Rolex 24 at Daytona at the wheel of not one but two cars: the #52 ORECA 07 fielded by PR1 Mathiasen Motorsports in the LMP2 class and the #74 Mercedes AMG-GT3 fielded by Riley Motorsports in GTD. Both cars crossed the finish line, the #52 ORECA 07 in 10th place overall and second in its class two laps from the winners, and the #74 Mercedes AMG-GT3 in 29th place overall and 11th in its class. This was the fifth time Keating participated in the race with two different cars.

Exclusive! C8.R Corvette 5.5L DOHC V-8 Pics and How the Flat-Plane Crank Alters Its Iconic Sound

There’s A New Engine In The C8.R Corvette, And It Sounds Nothing Like Its Predecessor.

They say beauty is in the eye of the beholder, and although that’s true, it can also be in the ear of the listener.

Since the Corvette first hit the streets back in the 1950s, it was imbued with the beautiful and nearly magical sound of V-8 performance. It was a deep, bass-filled rumble that just oozed a feeling of power. Over the years, the sound emanating from Corvettes, both on the street and at the track, had a distinctive note that became synonymous with the car. When the Corvette moved to the LS1 in 1997, the firing order was tweaked a bit, and although the sound did change, it still had that deep rumble that we all love.

002 2020 Rolex 24 hours Daytona C8R Corvette Engine Image Exhaust Sound
Chevrolet is super secretive of its new mill for the C8.R, so much so that it covered up the back hatch to keep out prying eyes. About all the team will say is that it’s a 5.5L DOHC V-8 fitted with a flat-plane crank. Power numbers are limited to 500 hp and around 475ish lb-ft of twist, but that’s all it will say. In fact this picture is about as close as you’re going to get to seeing the new C8.R engine.

But the only thing constant in the world is change. For the C8.R, Chevrolet Racing really changed things up with its new mid-engine marvel, but it wasn’t the engine placement that ended the car’s iconic sound signature. It was the engine itself. Gone is the deep baritone exhaust note, replaced instead with a high-pitched Ferrari-like sound. Think puberty in reverse. And although we love the sound of a wound-out Ferrari or other Italian supercars, having that pitch emanate from the back of a Corvette is something that will be hard to get used to. We’re not saying the sound is bad—it’s actually pretty badass—but it’s not even close to the sound signature we’ve come to associate with Corvettes.

009-2020-Rolex-24-hours-Daytona-C8R-Corvette-Engine-Image-Exhaust-Sound

The real culprit here isn’t the new 5.5L DOHC V-8 that Chevrolet moved to. Instead, it was the choice to go with a high-revving flat-plane crank. This drastically changed the firing order of the engine and eliminated the classic American V-8 sound that’s typical with the firing sequence of a traditional cross-plane crank. But we know what you’re thinking: “Well, this is just the race car, so I’m going to be able to get my V-8 rumble fix from the production car!” Well, yeah, for now. You see, for Chevrolet Racing to run this new DOHC flat-plane crank mill in the C8.R, it has to, according to the rules, run a similar engine in at least 300 production cars. So does this mean that an eventual C8 Z06 variant will lose its iconic exhaust note?

Chevrolet Racing tried hard to give race fans a great-sounding engine. And although the new 5.5L engine in the C8.R does have a unique sound, it’s nothing like we’ve grown accustomed to.

Corvette Poised for Sebring WEC Return

#3 Corvette Racing Corvette C8.R, GTLM: Antonio Garcia, Jordan Taylor, Nicky Catsburg

Corvette Racing set for COTA-Sebring double FIA WEC run with C8.R

Corvette Racing looks set to contest the 1000 Miles of Sebring, in what would be the second consecutive FIA World Endurance Championship outing for the new Chevrolet Corvette C8.R.

Sportscar365 has learned that provisional plans are in place to run the Sebring WEC race alongside its two-car factory GT Le Mans class program in the Mobil 1 Twelve Hours of Sebring the following day.

It would come as one of the prerequisites from the ACO, which has stipulated that the Pratt & Miller-run team must run in at least two regular-season WEC races in order to be guaranteed a pair of GTE-Pro entries for the 24 Hours of Le Mans.

The team ran the Shanghai WEC race in 2018 in addition to Sebring last year with its previous-gen Corvette C7.R.

While declining to comment or confirm on any WEC plans beyond its COTA entry, Corvette Racing program manager Doug Fehan said that it’s been their intention to run two regular-season races in the 2019-20 WEC season.

“Right now, that’s the plan but we’re running down a road,” Fehan told Sportscar365.

“We haven’t refined what exactly that plan is going to be. I couldn’t give you every detail and widget.

“We’ve been busy for a couple of years trying to race and design, build and develop the new car. This adds to the challenge of all of that.

“I think most people would understand that we don’t have it completely defined yet.

“It’s a case of dealing it in an orderly fashion.

“We can’t become overwhelmed too much with what’s going on down the road when we have to focus on what we need to accomplish [in Daytona] in a couple of weeks.”

While set to give the new mid-engined GTE contender its competition debut in the Rolex 24 at Daytona later this month, the car’s second race will come just four weeks later at Circuit of The Americas, with a single entry having been submitted for the WEC replacement round.

Fehan said details on that program, including drivers, have yet to be determined.

He explained the reason for doing the additional WEC races is to “try as best we can” to support the globe-trotting championship.

“We understand the value that has to the sanctioning body and the value to the global fan base,” he said.

“We know it’s important but they also know the business side of it that prevents us from doing both things. They get that.

“I think they also appreciate how hard we’re trying to make all of the accommodations we can to keep the ball moving down the field. 

“It’s not easy for us and they know it’s not easy for us and they appreciate that.”

No Issues in 2019 ‘Super Sebring’ Endeavor

Fehan said the team faced no issues in its double-duty endeavor at Sebring last year, in what was only the second-ever time the team raced three cars between two different series on the same weekend. 

In addition to its over-the-wall crew and several other staff, drivers Antonio Garcia, Jan Magnussen and Mike Rockenfeller took part in both Friday’s eight-hour WEC race and the around-the-clock IMSA enduro the day later.

“That worked out great,” Fehan said. “We were lucky because we had enough equipment.

“It’s not like you can piggyback what you have set up. You’ve got to have a completely additional set of stuff.

“Between stuff that we had in stock and stuff that we had for the Cadillac program, we had enough in place.

“That system is getting better and we learned from that on all the things we did right and all the things that we know we could improve upon.”

C8 Corvette ZR1 Will Get 900-HP, Twin-Turbo, Hybrid V8 Engine: Report

This is the first time that we’ve heard concrete news about a hybrid version of the C8, and their source has confirmed that it is indeed coming very soon. The supposed ZR1 will utilize the engine found in the Z06, a dual-overhead-cam V8 that happens to be flat-plane-crank and twin-turbo; similar to the one found in the C8.R race car. The hybrid system will be completely performance oriented, and will place an electric motor between the engine and transmission to increase output considerably to 900 horsepower. That’s not all, apparently, the C8 Stingray has some space in the front trunk that’s reserved for a pair of front-mounted electric motors that are said to increase performance and apply torque vectoring to aid the rear axle and its electronically controlled limited-slip diff, essentially meaning that the ZR1 will be all-wheel drive. 

More Tiny C8 Details:

 2020 Corvette Stingray Almost Had A Split Rear Window: Report

Furthermore, their source indicates that the rumor of the 4.2-liter Blackwing V8 engine from Cadillac being shared with Corvette models is false; GM gave Cadillac and Chevrolet the resources to design and develop two different V8s at the same time. The hybrid system also has the consequence of added weight and proper placement to retain performance and a low center of gravity, so your guess is as good as ours as to where Chevrolet plans to mount the entire system.


How the C8 Corvette’s Dual-Clutch Has Changed Since We Drove the Car

The new Corvette has an eight-speed Tremec DCT. We weren’t crazy about it in the pre-production C8 we drove, but engineers tell us the final version will be better.

For the C8 Corvette, Chevrolet abandoned the traditional manual and torque-converter automatic for a new, eight-speed Tremec dual-clutch. And in our Performance Car of the Year testing, the gearbox was the weakest component in the pre-production C8 Stingray we had on hand. It’s part of why the Corvette didn’t win.

In automatic mode, the DCT dolled out nice, snappy shifts, but when using the paddles, it could be clumsy. Too often we found ourselves running into the rev limiter, or having downshifts denied after a paddle pull. But, the C8 we drove wasn’t a finished product. There’s been development work since we drove the car, and that work will continue for the foreseeable future. At a powertrain engineering seminar held by Chevy last week, we asked Glen Hoeflinn, controls program manager for the DCT, what will change from the car we drove.

“Maybe you get some humpy-bumpy shifts here, you get a little bit of that there. That all gets refined out,” Hoeflinn said. “It’s in final refinement, and then it’s in final checks and looking what we’re doing and making sure that it’s behaving exactly [how] we want.”

“That’s what we’ve done since the car that you had. Doing all that refinement and making sure it’s ready to go for everybody across the all the cars.”

A dual-clutch presents unique challenges, no matter what sort of car it’s in. “There’s a lot of pre-selection interaction that goes on in the background,” Hoeflinn said. “It’s the same choreography” between the engine and transmission, he added, but without the “luxury” of a torque converter, there’s a lot more programming work involved.

As you’d expect, the transmission has different automatic shift strategies for the various drive modes, which adapt in real time. The more aggressive, the more spirited you drive, the more aggressive the car’s going to respond,” Hoeflinn said. “As you start to relax, the car’s going to start to relax.”

The DCT uses latitudinal and longitudinal accelerometers, and looks at information like throttle position and steering angle to gauge how the car is being driven, and react accordingly. For example, in Track mode with the transmission set to automatic, the car will downshift aggressively when the driver is braking hard into a corner, and hold upshifts until corner exit.

The C8 has two manual modes. If you pull a paddle while in Drive, you get a temporary manual mode, which automatically times out, or can be exited sooner by holding the upshift paddle. In this mode, the car will automatically upshift at redline. If you press the M button in the center console, you get full manual mode. There’s no time out, and the car won’t upshift at redline.

There are two other neat tricks available for drivers to exploit. First, if you hold the downshift paddle, the DCT will serve up the lowest possible gear. Do that while braking, and the transmission will keep downshifting as engine speed allows. And second, pulling both paddles at the same time is equivalent to pushing in the clutch pedal on a manual car, which allows you to rev the C8’s new V-8 as much as you want.

In the C8, the paddles are directly wired to the transmission control module (TCM) for quicker response times. “In other applications, from the paddle, the wire will go to the body control module and then from the body control module back over to the transmission. You have obvious latency there,” Hoeflinn said.

“It could be 25, 30, 40 milliseconds from the time you pull, to the time that transmission actually got the message. When you wire them directly from the paddle straight to the TCM, we’re getting the message instantaneously.” This doesn’t mean the paddles will give you a downshift that over-revs the engine—the TCM prevents that—it just helps reduce delay.

One of the headline figures of the C8 Corvette is its incredible acceleration. We timed a pre-production Z51 Stingray as hitting 60 mph in 2.8 seconds and running the quarter-mile in 11.2 seconds at 122 mph. With the C8’s Performance Launch mode, the car will actually use the inertia of the engine coming down between revs to propel the car forward. Chevy calls these “Boosted Shifts,” and they’re only used with a Performance Launch. In any other mode, they make the car feel unsettled.

From a mechanical standpoint, this new Tremec transaxle isn’t a radical departure from other DCTs. There are concentric clutches and input shafts for the odd and even gears. The even gears and reverse live near the front of the transmission, while the odds are at the back. A limited slip-differential is integrated within the unit. Base Stingrays get a mechanical diff with a 4.89:1 final drive ratio while Z51-pack cars get an electronic LSD with a 5.17:1 ratio. The overall gear ratio spread of 8.8:1 is the same regardless of differential.

The packaging of the transaxle is such that there’s a common oil sump—filled with 11 liters of Pentosin FFL-4 fluid—for all components. A cooler mounted to the top of the transaxle assembly means there’s no need for additional hydraulic lines, while two filters keep things clean. An externally mounted pressure-side filter requires replacement every 20,000 miles, while the internal suction filter mounted to the sump is a lifetime part.

We asked about why the C8 team didn’t try to do a manual. Hoeflinn and the other engineers present gave us a similar answer to Corvette chief engineer Tadge Juechter, when we interviewed him before the car debuted. They’d need to develop a new manual just for the C8, and considering the stick-shift market is shrinking, it would be an expensive endeavor seemingly without much reward. There are packaging constraints with the Corvette’s central backbone tunnel, too, which would require a hole to accommodate the shifter and gear linkage, hurting structural rigidity. Juechter also said the pedalbox would be cramped with a clutch.

Our first experience with this DCT was less than positive, but this is a gearbox that shows a lot of promise. We look forward to driving the finished product.

2020 Corvette Stingray Shown at Spring Mountain’s SEMA Display

Spring Mountain Motor Resort and Country Club, home of the Ron Fellows Performance Driving School, is located less than hour from Las Vegas and they bring a continent of cars and people to the annual SEMA Show at the Las Vegas Convention Center.

Drivers for Ron Fellows School provide hot laps for the attendees which is hella fun if you have ever had the opportunity to catch a ride in one of the ZR1s they have. In addition to the hot laps, Spring Mountain also has booth display at SEMA and featured prominently is the 2020 Corvette Stingray wearing the Ron Fellows Driving School livery.

We asked Spring Mountain’s Todd Crutcher send us some photos of the 2020 Corvette on display as it’s the only place at SEMA outside the Chevrolet display where you catch the C8 Corvette in the flesh.

Chevy had displayed a C8 Corvette with the Ron Fellows door stickers at both the Woodward Dream Cruise and Corvettes at Carlisle, but the car on display at SEMA is much more representative of the Ron Fellows livery that also features the No. 01 car number on the front and back while Michelin stickers are also featured. A windshield banner completes the look.

This C8 Corvette is a Z51 model and 3LT trim package and inside is the two-tone Blue leather interior. The Stingray also shows off the visible carbon fiber roof panel that’s only been spotted a couple of times.

There has yet to be any kind of announcement regarding a driving school for owners of the C8 Corvette at the world-class driving school, but we’ve been told to stay tuned as things are progressing. We do know that a continent of cars will be built for the school and that they will be used as part of the official GM training for dealerships who are selling the new sports cars. While the strike has messed up the original timeline for the school to receive their cars, we expect some sort of announcement will be made in the near future.

If you have purchased a C7 Corvette in the last year, your time is limited to take advantage of the 2-day Corvette Owner’s School that’s heavily subsidized by Chevrolet. To find out more information about the Corvette Owner’s school, visit SpringMountainMotorsports.com or call Melinda or Donna for details 1-800-391-6891. All Corvette enthusiasts are invited!

2019 Chevrolet Corvette ZR1 Review: Say Goodbye to the Bad Guy

Early-build C8 Corvettes are hard at work, ginning up enthusiasm for the biggest sea change in America’s sports car since the C2 dropped the stick axle. The 2020 Corvette is an extraordinary car that makes extraordinary numbers at an extraordinary price—and we would expect nothing less. But before we rush headlong into the mid-engine era, can we stop and appreciate the outgoing C7 one last time?

Because it seems unfair, really, that the 2019 Corvette ZR1 has already become a thing of history, just another Vette in the model’s long and storied line. This is the culmination of not just the most recent generation of Corvette, but also the entire 66 years of the front-engine paradigm. Certainly, it is the costliest Corvette ever (and the highest-priced vehicle GM currently sells), with our test car ringing the bell at $142,075.

You spend that money for more power than in a regular Stingray—300 horses more. This is not unlike having an extra V-6 Camaro engine bolted to the top of your Corvette’s 6.2-liter V-8. Except the ZR1 actually employs a supercharger, with which the big, bad LT5 can blow even the brick house down, making 755 horsepower and 715 lb-ft of torque. Chevrolet says all that power comes from using both direct injection and good, old-fashioned port injection, a trick that also helps the Silverado return better gas mileage.

At idle the ZR1 rumbles like a seismic event and its rips and crackles at full snort are the sounds of a natural disaster. Hang on and hope that you don’t do anything stupid, like keep your foot in it for too long or try to outsmart its eight-speed automatic. (A seven-speed manual is also available.) Things happen quickly in the ZR1 and there is no chance of running out of car before you run out of road. It may not produce the acceleration numbers of an all-wheel-drive Tesla Model S Performance, but the violence of internal combustion in the Corvette augments its own sensation of speed to produce a far more visceral drive.

Indeed, the ZR1 must rank among the baddest sports cars to ever roll on four tires. In this case, those are sticky Michelin Pilot Sport Cup 2s that owners should probably think about buying in bulk. Yet before the ZR1 was even launched, it was guaranteed to be overshadowed by the C8, just as it would be doomed to share most of its interior bits with the not-aging-so-well C7. Was it really only six years ago that this cabin seemed modern? But Chevy can’t really be blamed for spending money on interior upgrades for the new car rather than throwing good money after bad on this one-and-done special.

Behind the wheel, the view out over the vast hood of the ZR1 is like nothing likely to come again. The tops of its sharp fender creases still call to mind the outrageous C3, but they no longer seem like peaks compared to the mountain range in the center of the hood. The protruding carbon-fiber engine cover stands proud of the hood and is good for at least couple taps up on the power-seat adjuster. If the optional Competition Sport seats are too tight and the Track Performance package too stiff for the comfort of your average Corvette owner, well, those are items you add to your ZR1 when the pursuit of lap times render money no object.

Like its Z06 and Grand Sport siblings, the extra-wide ZR1 makes any road feel narrow, and makes narrow roads seem like goat paths. Thankfully its steering is prescient and immediate, giving the car an astounding athleticism. Talking about things like handling and grip after driving a ZR1 on the street is akin to holding forth on surgical techniques after binge watching Grey’s Anatomy. If the Cessna wing blocking access to the trunk isn’t a strong enough hint that exploring the limits of a ZR1 anywhere that doesn’t require a balaclava and helmet is a bad idea, maybe you’ve just sniffed too much of the ZR1’s resinous off-gassing. That cologne is yet another reminder that even at 218 percent of the price of a base Stingray, the ZR1 is still 100 percent C7.

With first tests of the C8 showing that it’s quicker to 60 miles per hour than the ZR1, the King of Corvettes has already abdicated its throne. It seems sea changes occasionally happen in the blink of an eye.

Current 2020 Corvette Orders Undergoing Updates to TPWs

Production of the new mid-engine 2020 Corvette Stingray was expected to start the week of December 2nd. But then the UAW strike happened, which pushed the earliest TPWs (Target Production Weeks) for those buyers with accepted orders back to January 20th at the earliest. Others have reported that updates to their TPWs pushed the start of their cars into February.

But now that the strike is over and the Corvette Assembly Plant has reopened, things are starting to get back to normal. After several days to assess their current situation, the Corvette team may be getting ready to make new adjustments to the current Corvette orders.

Over the last two days, we’ve heard from customers and dealers alike who have reported that current orders no longer have any Target Production Weeks attached them. Dealers are saying there are no TPWs in the order system.

This sounds like good news to us.

The Corvette Assembly Plant still has to knock out the remaining C7 orders, and plant spokesperson Rackel Bagshaw confirmed earlier this week that the plant will be down from November 18th – December 6th for C8 retooling.

If that’s the case, then perhaps we’ll see the first TPWs shifted back to December 2019. That would be fantastic news as then the strike would have only delayed the start of C8 production by just a week. Of course, the flip side is that TPWs could be moved even further into 2020 which is a very real possibility as well. Stay tuned on this and for those of you with orders, be patient!

2020 Corvette Offers Three Types of Removable Roof Panels

By: Johnathan Lopez

We’re still floored by the sheer number of exterior styling options Chevy will offer on the new 2020 Corvette C8. As evidenced by the online configurator, buyers will have a vast array of colors, stripes and accents to choose from when speccing the 2020 Corvette to their taste. But the new mid-engine Corvette Coupe will also offer no less than three individual removable roof panel options, offering up a body-colored, transparent, or carbon fiber aesthetic, as desired.

It’s also worth noting that Chevrolet is also expected to offer a proper C8 convertible model by the end of the year. Prototypes of the upcoming Corvette convertible have been spied several times in the last few weeks, each wearing some black-and-white camouflage and black netting around the roof section. Unlike the soft-tops of previous Vette convertible models, the 2020 Corvette Convertible will come with a retractable hardtop, resulting in an even more comfortable cabin.
