Ultimate Corvette Expected to Go PHEV

General Motors is plugging into EVs in a big way. And, among a wide range of electrified models set to come out over the next several years, one is expected to wear the Chevrolet Corvette badge.

GM CEO Mary Barra has repeatedly said the automaker is on a “path to an all-electric future.”

Several officials have acknowledge the C8 Corvette was designed to be electrified, though they have to confirm what form that will take.

A plug-based ‘Vette would focus on performance – likely nudging 700 hp or more — rather than mileage, though it likely also would be the most efficient version of the sports car.

When “spy shots” began circulating last week showing a plug hanging out of the nose of a new Corvette undergoing winter testing its was initially reported this was the rumored battery version of the sports car.

Parent General Motors subsequently explained that the pics had caught a conventional, gas-powered 2020 ‘Vette,” but the episode only underscores expectations Chevrolet is, indeed developing an electric Corvette — something an assortment of executives, including GM President Mark Reuss have taken pains not to deny.

If anything, Reuss effectively confirmed it is only a question of time, noting last July that the eighth-generation Corvette just coming to market will have to comply with the company’s “strategy of 0-0-0: zero emissions, zero crashes, zero congestion.”

But exactly what that means – or, more precisely, what form that would take – is far from certain.

GM officials have made it clear there will continue to be an assortment of different ‘Vette variants, perhaps more than we’ve seen in the past. During the July unveiling of the C8, several Corvette insiders told Ride that the new, mid-engine platform was specifically designed to allow the use of electric drive, with a battery pack placed below the load floor. What type of system it will be is the real question.

Only a few years ago, GM seemed focused on both conventional and plug-in hybrids, the original Chevy Volt being a good example of its PHEV strategy. But it has pulled the plug on Volt and is, for the most part, moving towards pure battery-electric vehicles. The current example is the Chevrolet Bolt EV, with an all-electric Cadillac SUV dues later this year. Among the nearly two dozen other BEVs under development: a battery pickup expected to revive the Hummer name.

For those who still think of battery drive as slow and boring, no need to worry, however. Making 100% of their torque the moment they start spinning, electric motors can deliver insane levels of torque given enough power. The “conventional” hybrid Acura NSX is one example. The plug-in Lincoln Aviator is the fastest and most powerful version of that SUV. And whether you’re talking Tesla Model S with Ludicrous Mode or the new Porsche Taycan Turbo 4S, pure BEVs can be blindingly fast.

If anything, says Sam Abuelsamid, principal auto analyst with Navigant Research, “no doubt about it,” a battery-based Corvette will be the quickest ever, “easily getting into the 700 horsepower range, with over 1,000 NM torque, and launching from 0 to 60 in under 2 seconds.”

A conventional hybrid, even one as exotic as the NSX, is unlikely, various sources indicate. The question, then, is whether Corvette goes all-electric or plug-in hybrid. Abuelsamid is one who believes it will be a BEV, though the evidence is still too vague to be certain. One high-level insider cautioned Ride last July it would be difficult to squeeze in enough batteries to deliver the range BEV buyers would expect. But pulling out the internal combustion engine and transmission could solve that.

Do expect the electric drivetrain to be all-wheel-drive, with motors front and back, every source has agreed upon, something critical in order to get all that power to the pavement.

Another unanswered question is what an electrified Corvette might be called. Some sources have hinted this will be the next-generation Z06, others that it might replace the old ZR1, the traditional pinnacle of the Corvette line-up. There has long been speculation Chevy might be working up a Corvette Zora, an homage to the sports car’s legendary first chief engineer, Zora Arkus-Duntov, and what better way to do that?

How soon? “A bit more than” 24 months was the best answer we could get from insider GM. That’s a bit further out than many expected, but the GM strike last autumn appeared to have pushed back development efforts.

WHY THIS MATTERS

The C8 is the first production Corvette to adopt a mid-engine layout, boosting performance to supercar levels at a fraction of the sale price global competitors demand. An electric ‘Vette, whether PHEV or BEV, would pose an even bigger challenge to exotic brands like Ferrari, Lamborghini and Aston Martin.

Big C8 news!

And we literally mean “big.”

With production of the all-new 2020 Chevrolet Corvette Stingray about to get underway next month, attention is now turning towards future variants. More specifically, the E-Ray, the first of two hybrids planned (the second likely named Zora), as well as the Z06, and, eventually, the ZR1. While we don’t have a precise timeframe as to when any of those will arrive, it goes without saying the Corvette engineering team led by Tadge Juechter is hard at work this very moment.

Details remain mostly vague, but GM Authority has learned something very cool about the C8 Z06. An inside source familiar with the project is claiming the C8 Z06 will sport a massive rear wing, even bigger than what’s found on the outgoing C7 Corvette ZR1. What’s more, it’ll produce higher levels of downforce and create less drag.

Although the C8.R race car has a big rear wing of its own, the Z06’s will differ in both appearance and functionality. Think more along the lines of the rear wing on the Koenigsegg Agera RS. Another unknown is whether or not the C8 Z06 will come with the rear wing as standard or if it will be optional. Some sources are claiming the Corvette team is leaning towards making it standard.

Assuming all goes to plan, the next Z06 could arrive in about two years’ time. Instead of the naturally aspirated 6.2-liter V8 with 490 horsepower and 465 lb-ft of torque, the C8 Z06 is expected to have a new NA 5.5-liter V8 with a flat-plane crank. Expect somewhere in the neighborhood of 600 hp.

Additional elements will include an improved suspension, brakes, and additional aerodynamic components aside from the rear wing. There shouldn’t be any mistaking the C8 Z06 for the C8 Stingray, even when the latter is equipped with the Z51 performance package. It should also go without saying the Z06 will command a significant price premium. A fully-loaded 2020 Corvette Stingray will surpass $100,000, so don’t expect the Z06 to cost any less.

2020 Corvette Stingray Convertible in Shadow Gray on Display at GM’s Detroit Headquarters

Photo Credit: Kevlar Bike- Corvette Forum

Inside General Motors’ headquarters known as the Renaissance Center in downtown Detroit is a large turntable that is currently featuring all eight generations of the Chevrolet Corvette. The new eighth-generation iteration of America’s Favorite Sports Car is a 2020 Corvette Stingray Convertible painted in Shadow Gray Metallic.

A Youtuber named portcarlingboats captured a minute of video as the new C8 Convertible spins by him on the turntable.

The visible cues on this Corvette show that it’s a non-Z51 model but it’s loaded with some great looking options that include the two-tone Natural and Black seats, Spectra Gray Trident Wheels and red brake calipers. We also prefer the bright Corvette emblems to the the darker versions on this exterior.

From portcarlingboats via YouTube:

Corvette C8 convertible on display at the GM Headquarters in Detroit Michigan on Sat Nov 23 2019; part of 8 generations of corvette convertibles on a rotating display from 1953 to today; C8 supercar, exotic car, european sports car; this is the car that will change the automotive for years to come; can’t wait for the all electric version to come- No sound

On his original post on the Corvette Forum, Kevlar Bike tells us he is Canadian and that the C8 Corvette on display inside the GM’s HQ is the closest C8 Corvette on display so he made the trip to check it out.

Shadow Gray is one of those colors that change drasticly when viewed in the direct sunlight and the lightings inside the RenCen does nothing to show-off the varying hues within. As a comparision, here is a quick walkaround of a Shadow Gray Metallic C8 at the NCM earlier this year from CorvetteBlogger contributor Jeremy Welborn:

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.

Corvette Chief Engineer Tadge Juechter is No. 4 on MotorTrend’s Power List for 2020

If you ever doubted the significance of the upcoming mid-engine Corvette, take a look at MotorTrend’s Power List for 2020, a compilation of the 50 most important names in the auto industry.

On the strength of leading the design of MotorTrend’s 2020 Car of the Year, the 2020 Corvette Stingray, Chief Engineer Tadge Juechter, unranked on the 2019 list, zoomed to the No. 4 spot in the 2020 ranking – ahead of two of his bosses, General Motors President Mark Reuss, who came in at No. 28, and GM Chairman and CEO Mary Barra, who ranked No. 6.

Said MotorTrend of Juechter:

“Juechter was able to squeeze the final dollops of power out of the C7 Corvette and then create a whole new beast: the long-awaited C8 with a mid-engine to increase power and performance. Despite all the tech, he engineered an affordable everyman’s supercar: 0 to 60 in 2.8 seconds for $60,000.”

Reuss, who moved up from No. 32 in 2019, earned the following praise from MT:

“Reuss is managing the day-to-day for an automaker as focused on the Corvette and Silverado as the goal to put 1 million electric vehicles on the road annually while developing autonomous vehicles and still making a profit. It means overseeing a leaner company going forward to fund the expensive tech.”

Barra, meanwhile, tumbled from the No. 1 spot in 2019 but still earned serious kudos from the magazine:

“Barra continues to be the tough, shrewd, and strategic leader that GM needs to remain profitable while investing heavily in electric and autonomous vehicles. Her decisive, no-nonsense approach has led to unpopular decisions to discontinue models, stop production, and cut jobs to meet long-term financial goals.”

Another GM leader, Chief Financial Officer Dhivya Suryadevera, was unranked in 2019 but made it to No. 23 for 2020.

MotorTrend says of her:

“In charge of GM’s finance department since 2018, Suryadevara is pivotal in achieving annual cost reductions of $4.5 billion through 2020—ensuring the automaker has the resources for ambitious EV and autonomous vehicle plans while keeping things running during a protracted labor strike.”

At the top of the 2020 list is MotorTrend’s Person of the Year, someone you may never have heard of, Peter Schreyer, President, Head of Design Management, for Hyundai Motor Group.

Writes MotorTrend of its No. 1 pick:
“Schreyer once said he wishes he could be a painter. The MotorTrend 2020 Person of the Year has taken a Korean canvas and created a masterpiece.”

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.

Why Carbon Fiber……..

Hans is asked many times…What are the benefits of Carbon Fiber? His answers are simple, carbon fiber provides solutions to most any application. Whether it is reducing weight and adding strength for a racing application, protection for our soldiers on land or by sea, or just making an exotic automobile a bit more exotic. Put simply when carbon fiber is built right like at deBotech it is plain BAD ASS!!!!!!! Check it out below.

 

New Z06 is the most aerodynamic Corvette ever…by Detroit Steel

It seems we’re learning something every week that makes us love the 2015 Z06 even more as the car revs up for its road debut early next year.

It’s the most capable, most track-worthy, highest-performing Corvette – you’ve probably heard it all by now.

However, the latest bit of news centers on the new Z06 being one of the most aerodynamically engineered vehicles on the market. Add that Z07 package to the mix, and the car holds the distinction of having the most aerodynamic downforce ever measured on a production car.
