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.

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.

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.

New Corvette Had ‘Reason to Go Back Out’ After Long Delay

Corvette “had reason” to take its No. 4 car back out on track after lengthy repair…

The “tough lessons” of the No. 4 Chevrolet Corvette C8.R’s tumultuous Rolex 24 at Daytona debut gave Corvette Racing confidence going forward with its new car, according to team manager Ben Johnson.

The silver No. 4 Corvette spent eight hours in its garage during the IMSA WeatherTech SportsCar Championship season-opener after a cracked bell housing resulted in an oil leak.

Having pitted at around 11 p.m. the car eventually returned to the track close to 8 a.m. but it still managed to be classified as a finisher, albeit 327 laps behind the GTLM class winner.

While not divulging the extent of the oil leak and associated damage, Johnson explained why the team kept its car in the garage for so long.

“To fix the problem we had to move the engine back,” he told Sportscar365.

“We tried to do it with the engine installed to expedite it but then we realized that if we wanted to get it back on track, we had to take time to take the engine out and put it back in.

“We just took our time to make sure that there was nothing else. At that point, we were no longer in contention, but we had reason to go out and just understand where else the car may have issues.

“It was just kind of a test session after that.

“I think we will go back and disassemble the whole car. We have some issues to address with the oil leak.”

Oliver Gavin, who shared driving duties in the No. 4 with Tommy Milner and Marcel Fassler, said the Corvette crew “wanted to be methodical” about its repairs which added to the length of time it spent in the garage.

The Englishman suggested that the car was starting to show signs of promising pace that it could have taken through the night had the leak not occurred.

“It was really tough on the guys, eight hours of working from midnight until eight in the morning, it was crazy,” Gavin told Sportscar365.

“As soon as that happened, we knew that our day was done and that we wouldn’t be challenging. It was a shame because up to that point, our car had just started to come along.

“It wasn’t super strong right at the start, but we were gaining on it as we went through the race. Could we have been in the mix at the end? Who knows. But there was a lot that we’ve learned from this.

“As a team, we figured a lot of stuff out today. Testing is great but you really see exactly where you are when you come to a race and see where your competition is.

“We’ll take that away and process the data to see how we can make ourselves and the car better for Sebring.”

The No. 3 Corvette fared better than its sister car with Antonio Garcia, Jordan Taylor and Nicky Catsburg bringing home a fourth-place class finish on the lead lap.

Johnson said that this car’s run wasn’t entirely straightforward, but it held up well enough to remain in contention for a podium heading into the final two hours.

“We had a slight clutch issue at one point, but we had fixed it after the first stop that we witnessed it, so it wasn’t a time loss,” he explained.

“But nothing held up that car specifically again.  We were really happy that all the execution, pit stops, driver changes… all things that you don’t get to test in anger until you reach the race, all went super well.”

Johnson added that the Rolex 24 has given the Corvette team confidence ahead of its next race outing at the ‘Super Sebring’ endurance racing double-header weekend in March.

“Coming away from our first race with one car on the lead lap… the issue with the oil leak is obviously very apparent, but when we looked at it we realized it’s a pretty simple fix,” he said.

“I think it raises everyone’s confidence that we can get through some of these early tough lessons and move on to Sebring in a much better spot.”

Garcia, Gavin uncertain of Corvette C8.R’s Daytona prospects

Corvette Racing’s veteran stars, Oliver Gavin and Antonio Garcia, are positive about the new mid-engined C8.R’s progress but are uncertain how it will perform relative to its GT Le Mans class opposition at this weekend’s Rolex 24 at Daytona.

Gavin’s full-time partner Tommy Milner set Corvette Racing’s fastest time in Roar Before the 24 qualifying  which decides garages and pit stalls, and he was encouragingly just 0.108sec off the top time in class, set by James Calado in the Risi Competizione Ferrari 488 GTE.

However, Gavin warned that the race will be several hours old before everyone gets an accurate picture of how the GTLM contenders match up.

“The C8.R is a brand new car and this is its first race outing,” said the 2016 Rolex 24 winner. “We won’t know where we are in respect to the competition, and they will be looking at us and figuring out where we’re strong and where we’re weak.

“You can pick up little bits and pieces during the Roar and even in the two or three practice sessions before the Rolex 24, but you never really get a great idea of where you’re at until you get five hours or so into the race.

“But it always comes down to the last two hours. It would be quite remarkable if we could come right out of the box and be super-fast, super-reliable and have a successful weekend the first time out.”

Two-time IMSA WeatherTech SportsCar Championship GT Le Mans title winner and 2015 Rolex 24 winner Garcia also sounded a note of caution.

“So far, the new Corvette has been quite decent in testing,” said the Spaniard who is entering his seventh season with the legendary team. “It is still very early stages for this car.

“Even though we think we are ready, there are things that can come up. We must do everything we can to make sure we are as prepared as possible. Then we can see what we really have.

“Our testing has been a consistent evolution between track days and simulator work. We’ve been able to develop a plan to develop the car even though we weren’t testing on the track. The correlation of data has been good. Everything that we have tested virtually is working in real life. That makes life a lot easier when you can use all your tools to improve.

“We continue to validate all the work we’ve done and what we find on the racetrack. We are on the right track.”

While Gavin and Milner continue to be partnered by Marcel Fassler for the endurance races, Garcia not only is working with a new enduro extra – Nicky Catsburg – he also has a new full-time partner.

Jordan Taylor, who in 2017 won the IMSA Prototype title with the team owned by his father Wayne Taylor, and has two Rolex 24 wins to his credit, has moved to the GTLM class with Corvette, replacing Jan Magnussen.

This continues a relationship with the Doug Fehan-run team that stretches back to 2012, the first of six years in which Taylor raced a Corvette in the Le Mans 24 Hours. Partnering Gavin and Milner, he won the GTE Pro class at Le Mans in 2015.

“I’m excited to go back into GT racing with Corvette in GTLM with all-manufacturer teams and all-professional drivers,” he said. “The class will get a lot of eyes on it with the first race for the C8.R.

“The race itself will be extremely difficult. I’ll have to get used to looking in my mirrors again! In testing, I was reminding myself to check the mirrors leaving certain corners so I could get in the habit of doing it for the race.

“So I’m looking forward to it. Overall wins are fantastic, but a win is a win; you still get a Rolex watch no matter what class you’re in! But for us in GTLM, the competition will be the same if not more difficult than in prototypes.”

Garcia: “Big Steps” to Come With Corvette C8.R at Roar

Corvette Racing drivers on anticipation of Roar Before Rolex 24 with new mid-engined C8.R…

Antonio Garcia believes there will be “big steps” to come in the Chevrolet Corvette C8.R’s development as the new-for-2020 mid-engined GT Le Mans class contender makes its public debut in this weekend’s Roar Before the Rolex 24.

The Pratt & Miller-built Corvette, along with Porsche’s 2019-spec 911 RSR, are the two all-new GTE-spec cars set for their first official competitive outings in IMSA WeatherTech SportsCar Championship competition during the three-day mandatory test.

While having already completed private testing at the 3.56-mile oval/road course, Garcia believe every lap will matter in their plan for the weekend.

“There is a lot to discover and develop,” Garcia said. “Usually your starting point is better than what you previously had.

“But this is completely different. We are still in the early stages with this new Corvette.

“There will be big steps for sure.

“I don’t know when we will get to the point where we will start making little steps. We need to run this car and we need to race it to find out where we are against our competition.

“We are concentrating on our own work. Whenever it becomes race time, we will know where we actually are.”

Garcia’s new full-season co-driver Jordan Taylor said they won’t necessarily be concerned about pace at the Roar, which will also set the pit lane and garage allocations through a qualifying session on Sunday morning.

The 28-year-old, who makes the switch from his family’s Wayne Taylor Racing operation, said little things, such as driver changes, will be a focal point as well once they achieve the targeted baseline.

“As many laps as we can get at the Roar and going through the program, getting all the drivers on the same page from a setup point of view and then the little things like pit stops and driver changes will be different than what we’ve had in the past,” he said.

“The car is a little more tricky to get in and out.

“Understanding that muscle memory of the process of getting in and out, where the seatbelts go, where the drinks bottle is, where the air hose goes… those little details that we haven’t refined that were refined with the C7.R are things that will show up in a 24-hour event, so those are things we will need to check off the list at the Roar.”

Gavin: “Very Structured” Plan for Weekend

Team veteran Oliver Gavin, who returns to the No. 4 entry alongside Tommy Milner, said that coming away with achieving 60 or 70 percent of their list will be considered a “big win” over the weekend.

“The team is going to have a very structured plan,” Gavin said. “And that’s one of the things that’s so good about Corvette Racing. We plan our time and fundamentally understand what all we have to work through and the list of things we need to achieve.

“The third drivers will need time in the car. We’ll all have to work through that program and procedure as best we can.

“Certainly we’ll learn a huge amount every time we go on track just with how certain tires work, how the braking package works, the aero setup, weight placement… all kinds of different thoughts that the team will look to work through.

“We know that of that list of 50 things we want to try and achieve, the chances are that if we can come away with 60 or 70 percent of that done, it’s a pretty big win.”

There’s plenty of video evidence of the 2020 Chevrolet Corvette C8’s presence at the Nürburgring, so it’s no surprise that that at least one of the C8’s numerous laps was a timed, balls-to-the-wall affair. Surprisingly, Chevy never revealed any lap times from any of the mid-engined car’s track sessions, but now there’s a report claiming that a lap time is pretty much on par with that set by a Lamborghini Huracan LP610-4.

According to Muscle Cars & Trucks, the C8 set a lap of the Nürburgring in 7:28.3. The aforementioned Lamborghini recorded a lap of 7:28 flat when tested by Germany’s Sport Auto, and over the course of a 12.9-mile, 154-corner lap, that’s well within the margin of driver error.

One has to be slightly skeptical of this claimed time, and not just because MC&T doesn’t disclose the source of its information—although the site has proven to be right in multiple claims surrounding GM products this year. The C8’s time is only some 11 seconds quicker than that set by a C7 Z51 in poor conditions, and with the gains made to the Corvette’s transmission and 6.2-liter V-8 in the C8 generation, it feels like that margin should be much bigger. Admittedly, almost everyone who has driven the C8 near its limits so far seems to say that the car’s suspension setup is a work in progress and that there’s a ton of untapped potential in the chassis. This means that quicker times may yet be possible even without increasing the Corvette’s power output.

But since the C8 is at least semi-believably as quick around the ‘Ring as an entry-level Lamborghini, we can only fantasize about what times the faster, seemingly inevitable Z06 and ZR1 will achieve. We know that one of the two will drop the cam-in-block, cross-plane crank 6.2 for a C8.R-derived V-8 with a lightweight flat-plane crank and dual overhead camshafts, which will offer greater horsepower per liter—and potentially a broader rev range.

This engine is rumored to make as much as 600 horsepower and 620 pound-feet of torque, though there’s no telling whether it’ll arrive on the scene for the Z06 or the ZR1 (or its equivalent), which will reportedly gain an electrified front axle and twin turbochargers for a total output of 900 horsepower. The mere concept of a Corvette with McLaren P1-level performance is enough to make anyone wave the Stars & Stripes.

The Drive contacted General Motors for a statement on the C8’s alleged lap time, and we will update when we receive comment.

Why the C8 Corvette Stingray Is So Quick

The mid-engine Corvette hits 60 mph in 2.8 seconds. Here’s how.

We could forever debate the philosophical implications of the Chevrolet Corvette’s switch to a mid-engine layout, but when it comes to physics, the repercussions are clear: moving the Corvette’s heaviest component behind the driver has a dramatic effect on the car’s ability to accelerate.

The Z51-package C8 and the outgoing Z51 C7 have similar weight-to-power ratios, yet the new car can sprint to 60 mph almost a second sooner. To understand why, you have to remember that a tire’s grip is related to the mass it carries. To maximize a powerful car’s ability to accelerate, you want weight over the driven wheels—but only enough so that the car can put its power to ground. Once you’ve accelerated and upshifted to a speed where traction isn’t a concern, weight is acceleration’s enemy. The trick to making a powerful car quick, then, isn’t to make it heavy. It’s to manage where the weight lies.

The front-engine, rear-drive C7 had a front-to-rear weight distribution of 49/51 percent—roughly 1750 pounds on its rear tires when the car wasn’t moving. The mid-engine, rear-drive C8 carries less of its mass on the nose—there are 2210 pounds on the rear tires when stationary. That’s 460 pounds more, which means considerably more available traction at the rear wheels.

Because weight shifts rearward under acceleration, that figure only improves as the car gains speed. To take advantage of this additional traction, Corvette engineers fulfilled their God-given purpose: they sent more torque to the rear wheels. Compared with the automatic-transmission C7, the C8’s first gear is a massive 21 percent shorter—the new car’s rear wheels experience a torque increase of more than 20 percent from that change alone. When you factor in the 10 lb-ft bump from the new V-8, the LT2, the C8’s rear wheels receive an additional 1350 lb-ft. No wonder the new Corvette wears 305-section rear rubber in place of the C7’s 285s.

Those gearing changes alone would account for almost half of the C8’s amazing 0-to-60 gap over the old car—a 1.0-second advantage. The rest, of course, is a function of the available traction at the rear tires, the LT2’s 35 additional horsepower, and finally, the dual-clutch transmission. Which can both shift without interrupting power delivery and perform a perfectly violent launch-control clutch dump.

And violent it is. The C8’s peak acceleration is just over 1.0 g, occurring almost a second after launch. That figure dwarfs the C7’s 0.7-g peak. And in case you’re wondering, at those respective peaks, the C8’s rear tires are under 2900 pounds of load, and the C7’s carry only 2150. The same dynamic weight distribution affects braking. Additional weight on the rear of a C7 would even out braking performance—under 1.0 g of deceleration, the car’s front wheels carry 66 percent of the car’s total mass, while the C8’s deal with just 57 percent. This means the braking components up front can be made smaller, and indeed they were. Front rotors shrank from 13.6 to 13.3 inches, and the rears grew, from 13.3 inches to 13.8.

Braking distances didn’t really change relative to the C7, but the C8’s switch to a brake-by-wire setup (there is no direct, physical connection between brake pedal and hydraulic system) carries a number of advantages. GM says the change allows for the deletion of the traditional brake booster and vacuum pump, moves that give more front-trunk space and better sightlines.

Those are certainly benefits, but they’re unlikely to be the real reason for the switch. Consider the by-wire system a tacit admission of a forthcoming hybrid Corvette. (Hybrids and most electric vehicles use blended brake systems that can continually shift braking duties between electric regenerative braking and the conventional friction brakes. The drawback is inconsistent and unusual pedal feel. A by-wire pedal eliminates this.)

Once we start thinking about a hybrid Corvette, the mid-engine layout really starts to pay dividends. Namely, the possible installation of electric motors on the front wheels, to provide all-wheel drive. Another traction path that would not have been possible with a front-mounted engine.

Finally, the mid-engine car’s added rear traction will be a huge benefit to the inevitable high-output internal-combustion variants. Like our C8 test car, the base C7 easily put its power to the ground. Only the supercharged Z06 and ZR1 models had trouble—and the next ones will have less. Add in electric all-wheel drive with torque vectoring across the front axle and it’s clear why the Corvette switched to a mid- engine layout.

Hang tight, my little puppy dogs, because this is going to be one hell of a thrill ride.

MISSING THE MANUAL

There’s only one reason to celebrate the death of the manual transmission in the Corvette: the C7’s seven-speed was geared so long that it sapped the punch out of holeshots. Able to achieve more than 50 mph in first (56 mph on C7s without the Z51 package), the front-engine car’s off-the-line acceleration wasn’t nearly as brisk as its mid-engine successor’s. First gear in the C8’s twin-clutch automatic multiplies torque by an extra 50 percent compared with the old manual—in fact, second is almost as long as the manual’s first. Gearing a manual C8 with ratios similar to those of the dual-clutch would slow the 0–60 sprint by the time it takes to make the two shifts between a standstill and 60. The delta would likely be about half a second.

I don’t know about you, but I’d be fine with a manual-transmission C8 capable of 3.2 to 60. On second thought, there’s no reason to celebrate the death of the Corvette’s manual transmission. Now get off my lawn.

Chevy Corvette C8 vs. Ford Mustang Shelby GT500: A Track Comparison

Forget Mustang vs. Camaro. Ford’s Shelby GT500 is ready to challenge Chevrolet’s flagship C8

Mustang vs. Corvette? Go ahead, pinch your thumb and index finger to the bridge of your nose, squint your eyes, and blink hard. When you look again, the words on the page won’t have changed.

Rarely has MotorTrend conducted (or concocted) such a bold comparison. But it’s a mad, mad new world we’re in now. Forget the Blue Oval’s sacrosanct rivalry with Camaro, which had always left the Corvette to chase the elusive, pricier Porsche 911.

Oh sure, the base pony car models will still compete, same as always. But the top-end Mustang GT500 is so excellent it deserves higher-octane competition. The final piece of evidence: The Mustang Shelby GT500 costs more than Chevrolet’s new mid-engine Corvette supercar when similarly equipped. Game on.

The C8 Corvette and Shelby GT500 have stirred up more buzz than anything else that’s come from the Motor City in recent memory. After decades of teases and concepts, the ‘Vette finally slides the engine back in the chassis to join the transaxle aft of the driver’s derriere. And after the extremely successful Shelby GT350, which finished a sharply creased second place in our 2019’s Best Driver’s Car, Ford brought in even heavier artillery with a load more horsepower and torque.

These two contenders offer different kinds of appeal, both inspiring great desire in the high-performance enthusiast world. Both offer capabilities that measure well against far pricier foreigners, without the kind of sacrifices that used to come with the label “Made in America.” Gone (mostly) are the long-muttered utterances about cheap features and fixtures, crude handling, and lack of refinement.

Of course, when you look inside these two cars, there’s an immediate difference. The Corvette is an American interpretation of a mid-six-figure European supercar; the Shelby has nearly the same interior as that rental Mustang convertible at the Hertz counter at LAX—albeit with better seats and some minor brightwork tacked on to disguise its cheesy rotary shift knob and plasticky switchgear. Ford’s interior guys still have some work to do before they can declare their Shelby variants to be world-class premium.

But this is not a comparison test for value shoppers who peruse our Buyer’s Guide, niggling over inches of legroom and warranty coverage.

This is a track test—the literal interpretation of where the rubber meets the road.

The C8 Corvette has come of age—finally, I might add—with a style and behavior that bring to mind a word like “sophistication.” The Corvette’s new shape will sit well with the German and Italian exotica in the valet lot at the country club.

The Shelby GT500 comes from another, more purely American place, the pony car. But since the arrival of the S550 chassis in 2015, the muscular Mustang and its more powerful derivatives have risen above the hot rods of yore, to compare well with European icons.

The ‘Vette excels with exotic appearance, precise and agile handling, and balanced power with a nice rush of strong, smooth, jetlike urge. The Muscle-tang crushes like a bodybuilder with brains. Its huge forward forces do not overwhelm its chassis, as in many of the beloved classics we’ve known before.

The C8 Stingray carries a lithe, striking new shape that will grab attention from a block away. Its lines do a terrific job of conveying more of a sense of value and beauty, yet it’s still imbued with a half-century-plus of genetic identifiers. I predict this car will generate more than a few “Oh, wow!” reactions from the public long after it has gone on sale.

The Mustang is a beefed-up beast with bulging biceps, based on our well-known sporty coupe. It will light up the pony car crowd, certainly. But among the elites, the Shelby’s familiar muscle-bound shape may still result in upturned noses, window-rattling V-8 rumble or not. Where the Mustang scores more points in this contest is in its competence in motion.

At speed, the ‘Vette’s strongest dynamic assets are described in a list of two: first, low polar moment, and second, forward traction. Chevy engineers have created a machine that benefits in exactly the ways it should: more centralized mass and the resulting rearward weight bias.

The Corvette has long been the bad boy of the racetrack, the Bart Simpson of supercars: rude, loud, cheap, unpredictable, and hard to handle, but fast and fun in its own brash way. Now, the Corvette has finally grown up. The C8 Corvette is more sophisticated, capable, and mature.

When the majority of the weight in a chassis is nearer the center of gravity, the car will change direction more eagerly. Formerly carried way up front under those arching fenders, the big engine actually resisted the steering tires as they tried to pull that hunk of metal around to face the apex of a turn. The amidships engine makes the steering feel responsive, more direct, and more precise. It’s less work. The new ‘Vette slices its way into a bend in a most delightful way.

Too much, sometimes—and this is the tricky part of the setup. Quick response can overwork the rear tires and create oversteer. In several high-speed tests, and again here at Virginia International Raceway, we have found some of that in the C8’s track personality. It really will point to the apex entering a corner and sometimes overdo it and end up sideways, with the widely adjustable stability control switch fully off (thank you for providing us with that choice, Chevy).

But when you apply your American V-8 torque, then you find the greatest improvement in driving the American Sports Car: It puts ponies to pavement. The C8 hooks up. Chevy has taken advantage of placing the engine over the rear wheels, and that loading successfully creates forward thrust far better than any Corvette before. The new ‘Vette launches hard from a slow corner or a stoplight/dragstrip. Check out that 0-60 time, beating cars with far higher power ratings and even some with all-wheel drive. That, my friends, is traction.

In fact, the ‘Vette transfers weight rearward so well that it sometimes goes into another kind of slide: understeer. The front loses grip a bit prematurely as a result of the light front loads. What to do? Is it bad? No, but this is a brand-new baby, and there’s still something to be learned. We believe we will see the C8 Corvette improve further as the Chevy team learns more about this all-new mid-engine phenomenon.

In street-tuned mode dashing around VIR, the ‘Vette revealed deliciously instant steering response. It was quick and stable as I carved into a corner, and it revealed snappy trailing-throttle oversteer when I released the brake. Both are clearly influences of the mid-engine low polar moment.

As I accelerated off slow corners, like VIR’s Oak Tree, the C8’s ground-gripping traction rockets the car forward, and it remains well balanced even though it feels like it might wheelie. I found a consistent gradual side slip in third and fourth gears exiting faster sweepers. The C8 has more power oversteer at 80 mph than it does at 40, which is unusual.

The new Corvette’s braking was strong and stable with moderate nose dive. There was some isolation, if not the degree of e-pedal numbness I feared, and the brakes were cooled with some really nice Z51 brake ducts. Last, there was no more float, better suspension damping, but not harsh.

Crawling under the hood, we then adjusted the C8’s suspension to its track settings—which simply comes down to much more negative camber, front and rear. When added to the 8 degrees of caster (the same in Street or Track mode), the Corvette creates camber gain when the wheels are turned, which is especially good for tight turns, and a strong self-centering force for stability and good on-center feel.

High caster will also cross-weight a chassis because the outside wheel swings in an arc upward as the inside wheel swings down. These will both typically work to reduce the understeer that we squawked about in earlier tests.

The effect of the added camber was much improved grip everywhere, reducing but not eliminating traits of midcorner understeer and drop-throttle oversteer and raising speeds with better manners. The basic traits of midcorner understeer and trailing-throttle oversteer were still there, just not as much.

In Track setup, the Corvette’s lap times improved by 2 to 3 seconds with less falloff and better grip on a long run. Tying this all together was an eight-speed dual-clutch transmission that worked quite well at full chat, completing the performance of a much improved product. Far more than deserving of the title, this fresh offering is a 21st century new chapter, with more room to improve. One step back with the engine is a giant leap forward for the Stingray.

The GT500, on the other hand, has sprung from the loins of another highly regarded thoroughbred, the GT350. As such it comes from a known source that has been developed for years. It shows on track, especially.

Whereas the C8 is precise, the GT500 hoons. Toss it around. Grab it by the scruff of the neck. This pony encourages aggression. Its version of refinement manifests in confidence for the driver. And the GT500 works in both standard and Carbon Fiber Track Pack form. It is beautifully balanced on track. The steering stays alive all the way through a corner. Quick turn-ins show no evil twitches. Pouring on the ponies rockets it down the straights, and slides come slow and controllably. Within reason.

There’s that word again: reason. Use it when you squeeze down the Shelby’s accelerator. The supercharged cross-plane Coyote-based V-8 clearly makes all of its advertised 760 horsepower. This is another step into the Brave New World of high technology, and overeagerness with that gas pedal will be rewarded with jail and/or hospital time.

Every one of those ponies made themselves known as the Mustang devoured the long back straight at VIR, touching nearly  170 mph, lap after lap. No power fade here, unlike some other American blown V-8s making similar numbers.

The Coyote belts out a stirring bellow or calms to quiet as a mouse with just a switch of the electronic valves in the dual exhaust, allowing you to decide whether to wake the neighbors.

All that thrust goes through a new Tremec dual-clutch seven-speed that exhibited fine behavior on the street and flat out. Manual shifting during a hot lap is just a distraction, and the GT500’s auto mode rivals Porsche’s PDK (yes, really) and does everything I would do, anyway. It even had the savvy to hold a higher gear in places rather than constantly throw out raucous downshifts.

On straights, there’s a rewarding “over-torque” feature that gives a little extra shove on each shift, like a manual power shift. Yet in corners, I felt the Tremec smooth those out. Impressive. The track program is really dialed in. The Ford team should be proud.

This thrust twists a trick carbon-fiber driveshaft into a Torsen gear-type limited-slip differential—a good choice for a front-engine chassis because it doesn’t lock up much off power. This helps get the GT500 pointed into the turn, and it’s also a non-wear item, unlike the clutch-type diffs.

If the driver remains very responsible with the right pedal, the Shelby is responsive and stable. The MagneRide shock system soaked up the curbs and bumps, but it floated a bit under the loads of pro speeds. Happily, though, when the PS4S tires did break loose, it was mostly a gradual, even enjoyable experience. The GT500 has that magic combination of steering response at the limit: the ability to tighten its line while loaded laterally in the middle of a corner, without losing grip at the back.

The Shelby handles this great grunt very well—even with its traction/stability control fully disengaged. (I don’t recommend this unless you’ve completed several professional driving schools, one of which Ford offers with the purchase of a GT500, or have won Daytona at least once.) It’s an incredible thrill, breathtaking, to lay the pedal to the metal. But it requires skill to handle that thrill.

Stopping this rig were perhaps the largest rotors (16.5 inches) and Brembo calipers I’ve yet to experience. Although the big Shelby could dive deep, deep into the tight corners VIR presents at the culmination of its long straights, it was here I could find my only real complaint: a bit of a long brake pedal, which was a little disconcerting at 170 mph. No fade but some squish. They even bled the brakes for me, yet both test Shelbys felt spongy. This was surprising because I recall complaining that the GT350’s brakes were too strong, requiring only a big toe. Perfect would be somewhere in between

The incredible performance capability of the new Shelby (especially with the Carbon Fiber Track package) moves the Mustang into the supercar realm, it pleases me to claim. Both Shelby models provide such thrills that they represent good value even at these prices—driving with confidence-inspiring and consistent speed that is rare to find at any price.

So, to the numbers: Lap times for the C8 Z51 and the standard GT500 were quite comparable, though achieved in different ways. The Shelby evaporates the straights; the C8 carves the corners.

The Shelby carries the load of your family, so in spite of its fantastic, predictable balance, the Corvette can leave it in the twisties, driven precisely.

Once we tried the GT500 equipped with the Carbon Fiber Track package, however, it was all over for the street ‘Vette. The CFTP Shelby is magic on the racetrack, wearing R-compound Sport Cup 2s, carbon wheels, lower and firmer springs/bars/shocks, a proper wing and hell-yes-they-work aero fitments, and much more. Fire it up, and the Shelby is long gone in a blaze of glory.

So here’s the greatest difference between these fantastical motorcars. Shelby: raging, proficient power. C8 Corvette: precision, potential, and style. The price, similar. The choice, yours. The pleasure, ecstatic.

Daily Driver 2019 Corvette ZR1 Runs the Quarter Mile in 8 Seconds

With the C8 Corvette on the way, the 2019 Corvette ZR1 has sort of slipped from our collective consciousness, yet every once in a while a video comes along that snaps our focus back to the most powerful Corvette ever made.

It took the tuners over a year to unlock the secrets of the ZR1’s ECU, but thanks to HP Tuners and shops like Houston’s Late Model Racecraft, the true potential of the supercharged LT5 V8 has finally been unleashed.

YouTube channel High Tech Corvette calls this ZR1 one of the fastest in the country right now and we agree as we watch it blast through the quarter-mile in 8.7 seconds at over 155 mph.

With the drag radials on the car, this ZR1 hooks up so well that even removing the rear high wing only saves a few hundredths on the clock.

Hennessey Performance Offers First Look at Packages to Tune the C8 Corvette Up to 1200 HP

Texas tuning shop Hennessey Performance has shared some initial information and photos today as they begin to detail their plans to tune the 2020 Corvettes with the top package offering a whopping 1200 HP.

The HPE1200 package will feature a specially-built twin-turbo LT2 V8 with upgraded internals including forged aluminum pistons and forged steel connector rods. The HPE1200 Twin Turbo C8 Corvette will also see its factory dual-clutch transmission upgraded and fortified to handle the additional power.

“We expect the new C8 Corvette to be an excellent platform from which our clients can further personalize their cars, which obviously includes adding more power and performance,” said company founder and chief horsepower evangelist, John Hennessey. “Over the past several months we have had hundreds of inquiries from C8 buyers wanting to know what we will be offering for the new Corvette. Thus, we created an online questionnaire and have received over 250 completed forms and getting more every day. The customers are telling us what they want and big surprise – they want more power!”

Not just content to tune the engine, Hennessey’s C8 Corvette packages will also offer its signature “CarbonAero” carbon fiber body upgrades that includes a front splitter, air dam, and a rear carbon fiber wing. HPE will also offer an upgrade to the Brembo brake systems, as well as an upgraded Penske suspension, and wheel/tire upgrades.

Hennessee says a stainless-steel exhaust system upgrade is also in the works as well as a 700-hp supercharger system once the car’s computer can be accessed for tuning.

“We are very excited about the new C8 Corvette and have big plans for it,” said Hennessey. “From mild to wild, we plan to offer a wide variety of track-tested parts and upgrades that come with a warranty. We’ve modified over 500 C7 Corvettes since 2013 and expect to upgrade many more C8 Corvettes starting in 2020!”

Most Expensive 2020 Chevy Corvette Convertible Costs $113,955

Configurator with pricing info is up, so we’ve decided to max it out.

We’ve been periodically checking Chevy’s website for the Corvette C8 Convertible configurator ever since it went up at the beginning of October to see if there’s pricing available. You can finally know how much the desired spec is going to set you back as the configurator now has all the pricing details included. Much like we did with the coupe a few weeks ago, we’ve decided to max out the online builder in an attempt to find out how much a fully loaded Stingray Convertible costs.

We’re not going to go through each and every option as we did in the previous post because most of them are identical. It’s worth pointing out the convertible commands a $7,500 premium over the coupe and it starts at $67,495 for the entry-level 1LT. Go for the better-equipped 3LT and the price jumps to $78,945, and then you can add this $995 Long Beach Red Metallic Tintcoat paint and a dual racing stripe also priced at $995.

The most expensive options available for the C8 Convertible are the $5,000 Z51 Performance Package and the $4,850 Grounds Effect Kit, but on top of these, you can also add the $2,095 grille insert and $1,145 side mirror caps both finished in visible carbon fiber. Another pricey option is the $2,695 wheel set measuring 19 inches up front and 20 inches at the rear, with a five-spoke design and a Performance Pewter-painted finish.

If you truly want to go all out with the configurator, Chevy will be more than happy to provide you with a two-piece leather travel bag set for $1,450 as well as indoor and outdoor car covers each priced at $460. Inside, a carbon fiber trim adds $1,500 to the final bill, while the Competition Sport bucket seats are an additional $500.

With all the boxes ticked, you’re going to end up with a 2020 Corvette Stingray Convertible that costs $113,955, plus an additional $110 worth of dealer-installed

As you’re probably aware by now, production of the C8 has been delayed until February 2020, so it’s going to be a long wait to park the new Corvette in your garage.

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.

 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.

Highlights of the 2019 SEMA Show in Las Vegas

SEMA is the United Nations conference of all things aftermarket, and here’s some of the best stuff we spotted there.

1.Quintin Brothers Dodge Challenger

This 1000-hp Dodge Challenger went on a wild adventure after it arrived in Las Vegas. Vermont-based Quintin Brothers Auto & Performance had their truck and trailer stolen days before the show. Their custom Challenger was inside. Video surveillance helped track down the perp, but when Nevada state trooper Adam Whitmarsh tried to block the stolen Challenger into a parking space, the suspect rammed the Trooper’s Ford Explorer and escaped. After exiting the parking structure, the suspect smashed through a fence and drove the stolen Challenger across a nearby karting track—during a karting event. He eventually ditched the car and was later arrested. The Quintin Brothers and their Dodge Challenger arrived at the SEMA show wearing battle wounds from the wild chase.

2. Chevrolet E-10 Concept

It’s not an engine, it’s a motor. The Chevrolet E-10 concept is a 450-hp electrified C-10 pickup. Typically the only time a 1970s Chevy pickup is plugged into anything, it’s connected to a trickle charger. The E-10 has its batteries in the bed. The two electric motors seen here are called eCrate motors, a nod to the popular Chevy crate engines that can be found swapped into just about anything. GM claims the E-10 can complete a zero-to-60-mph run in about five seconds with a quarter-mile time in the high 13s. A Tesla P100D might be quicker, but it doesn’t look as cool.

3. Vibrant Performance Titanium Chair

Had Game of Thrones producers used Nissan Skylines or Toyota Supras instead of dragons as source material, this might be the Iron Throne. Vibrant Performance didn’t have to vanquish their enemies to build the thing, but they did use more than 50 pieces from their lineup of titanium exhaust products to construct what’s likely the most uncomfortable Adirondack chair on the porch. But it’s fun. Feeling exhausted? Have a seat.


4. Hyundai Veloster Grappler Concept

You’re unlikely to see a Hyundai Veloster on an off-road trail, let alone a dirt road, but this overland concept is out to change that. The Veloster Grappler concept is equipped with typical in-car camping accessories like a rear-hatch tent, solar panels, LED light bars, big all-terrain tires, and a roof basket to carry a spare. It’s still pretty low to the ground, and the tire clearance isn’t ideal for crawling, but it’s a concept. We’d pitch a tent with this thing.

5. Toyota Supra Wasabi Concept

Toyota’s Genuine Accessory Team cooked up a color for this concept that we hope will soon find its way onto a Camry. This Supra’s paint mimics wasabi paste and features white accents on the brake calipers, mirrors, stripes, and spoiler. The forged-aluminum wheels were designed at Toyota and have center caps with the original Toyota emblem. Ohlins coil-overs drop the Supra concept two inches. This was one of many Toyota Supras at the show.

6. AEV Jeep Gladiator

This Jeep Gladiator is equipped with all the proper get-dirty-quick gear. It has tough Bilstein dampers, a lifted suspension, and 37-inch tires. American Expedition Vehicles (AEV) is known for swapping big engines into off-road vehicles and then adding lift kits and other off-road accessories. They’re also responsible for the coolest parts of the Chevy Colorado ZR2 Bison. This year AEV brought three green machines to show off their latest accessories.

7. 1999 Honda Civic Si Super Street Build

Was this the car that sparked the movie The Fast and the Furious in 2001? It sure looks like it. Honda brought a handful of concepts to the show in celebration of its 60th year in North America, and what better way to do it by showcasing the Civic Si Super Street magazine modified for the Civic Si Challenge in 2000. If you collected buckets of Mattel die-cast cars as a kid (or shamelessly as adults, like us), this car might look familiar.

8. Nissan Frontier Desert Runner

The current-gen Nissan Frontier might be 16 years old, but this concept proves that Nissan knows what people at SEMA want in a truck: tons of suspension, awesome off-road tires, some type of light bar, and a 600-hp 5.8-liter V-8. In the meantime, we can only hope one of these ingredients get put to use on the upcoming Frontier refresh.

9. RTR Rambler Ford Ranger Concept

The RTR Rambler Ford Ranger does everything right without going too far. Ford chose 33-inch Nitto Ridge Grappler tires with custom RTR Tech 6 wheels, because they know anything bigger than that will be unnecessary in most cases. Three LED light bars are tastefully tucked into a custom front grille to complete an almost Ranger Raptor–like appearance. A two-inch suspension lift is installed as well as heavy-duty rock sliders, which act as both a step and as extra protection against rocky terrain. It’s a simple package done well, saving the flashy stuff like wild paint for the Insta-campers.

10. 1972 Honda N600

If it looks like this 1972 Honda N600 has a motorcycle engine under the hood, it’s because it does. This oddball is powered by a Honda VFR 800-cc V-4 motorcycle engine that puts power to the rear wheels. Although the car itself predates the era of high-revving VTECs, with the bike motor installed, this is likely the only N600 with a 12,000-rpm redline. This was one of several cars Honda showcased at the SEMA show.

11. Honda Civic Si Drift Car

This is a peek under the hood of a 926-hp Honda Civic Si. The engine is turned longitudinally and transforms a front-wheel-drive coupe into a rear-wheel-drive drift-spec machine. The work was done with help from Jeanneret Racing and Olson Kustom Works.

12. Chevrolet Silverado ZR2 Prototype

We saw this Chevrolet Silverado Desert race truck back in early October, when it competed in the Laughlin Desert Classic, a 17-mile race event in Nevada near the Arizona border. It was there for “engineering development,” but we still think it’s a preview of an upcoming Silverado Z

13. Honda Rally Passport

Honda R&D in Ohio built this rally-ready Honda Passport in their spare time. It has already survived a handful of rally competitions, finishing second in its class at the Southern Ohio Forest Rally. It has had typical safety additions like a roll cage, but other than that it’s unchanged except for tires, brake pads, wheels, and skid plates. Oh, there’s also the addition of a hand-operated hydraulic brake, for epic drift action.

14. 1968 Ford Bronco

There’s been plenty of buzz lately about the upcoming Ford Bronco, which is expected to debut in early 2020. A collaboration between Jay Leno and Ford, this Bronco has a supercharged 5.2-liter V-8 from the Ford Mustang Shelby GT500 and a five-speed manual transmission. The restoration maintained the simple beauty of original Bronco. The 18-inch steel wheels by Detroit Steel Wheels are a great combination of old style and modern needs. The Bronco’s Tonight Blue color would look great on a Mustang or F-150 Raptor.

15. Hyundai Veloster N Performance Concept

The Veloster N is quick, but this Veloster N Performance concept is quicker. Hyundai modified its hot hatch with carbon fiber for the front splitter, side skirts, rear diffuser, and spoiler while adding carbon fiber to each wheel’s center caps. The suspension is made up of Extreme Racing coil-overs and H&R coil springs with aluminum chassis bracing to add rigidity. Orange-accented interior bits stand out among more carbon-fiber pieces and an Alcantara dashboard.

16. SpeedKore Dodge Charger

Routed through the front fender of a 2019 Dodge Charger Pursuit is the exhaust from a 1525-hp Dodge Demon V-8. This project, put together by SpeedKore Performance Group and MagnaFlow, began as a police car. After fitting a carbon-fiber widebody kit, they turned it into something that would outrun police cars. The stock supercharged 6.2-liter V-8 was transformed into a twin-turbo engine and received an upgraded upper intake manifold designed to withstand the 26 psi of boost.
