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.
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?
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.”

The 2020 Corvette Stingray was named as one of the three finalists for the prestigious North American Car of the Year Award and the winner will be named Monday morning (Jan 13th) in Detroit. The all-new mid-engine Corvette does have some stiff competition as it’s facing off against the redesigned Toyota Supra and the Hyundai Sonata midsize sedan.
If you’re looking for a scouting report on the three finalists, you’ve come to the right place!
In this recent episode of Autoline This Week, host John McElroy is joined by panelists Gary Vasilash, Jeff Gilbert and Lindsay Brooke to discuss the contenders up for what is by far the most important vehicle award of the year. All four members of the panel are “NACTOY Jurors” who tested each of the cars and they all weigh in on the strengths and weaknesses of each vehicle.
After watching this episode, I am feeling pretty good about the Corvette Stingray’s chances, but that Sonata does have a ton of style and technology for a $30K vehicle so it won’t be a given. Check out the full conversation below:
From Autoline Network via YouTube:
The North American Car, Truck and Utility of the Year (NACTOY) jury comprises roughly 50 automotive journalists from the U.S. and Canada. Every year they vote on the best new cars, trucks and utility vehicles that came out in North America. Three of the NACTOY jurors join us on Autoline This Week to discuss the three cars that made it to the finalists’ list, as well as some of the cars that did not make the list. They also predict which vehicles will win the awards for best car, truck and utility.

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.”

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 are several approaches one can take when they set out to restomod a Corvette Sting Ray from the ground up. A person can begin with a perfect example of a factory original car or they can find a Sting Ray in need of so many repairs that the average person would choke at the expense needed to bring it back.
For Dr. Van Bingham, there was a specific plan. The choice was to find a clapped-out Corvette, and it had to be a 1967 Sting Ray coupe. Owning a C2 Corvette Sting Ray has been a lifelong dream for Van. Years ago, at 18 years old, he found a 1969 Corvette L88 for sale but didn’t have enough to buy it. Coincidently, another doctor Van knows—a specialist in his same field—bought that ’69 L88 and years later sold it for a reported $550,000.
How Van ended up owning a ’67 Corvette Sting Ray so far over the top in comparison to a garden-variety ’67 Sting Ray can best be attributed to “one thing leading to another.” Tray Walden at Street Shop referred Van to B Rod or Custom in Knoxville, Tennessee, and the project grew wings from there. The car selected was a $25,000 big-block ’67 coupe that turned out to be a lot rougher than first thought. Upon dismantling the ’67, B Rod’s Larry and PJ Burchett discovered the birdcage was rusted out far beyond usefulness. That set the wheels in motion to fabricate a new birdcage and ultimately created a new product for B Rod to offer Corvette owners.
The starting point for the project was to commission Eric of Eric Brockmeyer Design to pen a concept illustration for Van to approve. The chassis, as is for all Corvettes B Rod builds, is from Street Shop and is constructed from mandrel bent 4×2-inch steel tubing and based around C7 suspension components. The front coilovers are QA1 and a 1-inch sway bar capped with billet endlinks spans C7 spindles carrying 14-inch Z51 disc brakes. The rack-and-pinion power steering is a Flaming River unit made to Street Shop specs steered with an ididit Corvette-style column topped with a Billet Specialties steering wheel.
The C7 rear suspension is damped with shock absorbers and springs custom-made for Street Shop to use with its in-house machined lower billet mounts. Rear brakes are Z51 discs and body roll is controlled with custom 3/4-inch sway bar. Cast in aluminum alloy, the Super 8.8 differential limits wheelspin with a Truetrac unit and packs 3.50 gears. Custom Street Shop axles are made by the Driveshaft Shop. Fashioned after 1967 Corvette N89 cast-aluminum bolt-on wheels, the one-off Forgeline wheels measure 19×9 shod with Nitto Invo 245/40ZR19 tires in front and 20×12 mounted with 345/30ZR20 tires in the rear.
B Rod designates Van’s Sting Ray a “Wide Body” because wide wheels demand a very wide space. From the quarter-panels forward to the nose, four inches has been added to the car’s width. B Rod manufactures complete Corvette bodies and Wide Body C2 creations using press-molded fiberglass. Equipped with C7 suspension, the Street Shop chassis requires modified floors, hence a B Rod-modified floor and widened wheeltubs were utilized. B Rod purchased a new roof deck, taillight panel and hood surround from Lee Bumb Composites. The custom-made billet aluminum grille by Dan Baker’s Alumicraft rests beneath LED quad headlights by RestoMod Tech. Dan’s Polishing Shop did the chrome-plating work.
In Larry Burchett’s words, “The next step in the process was forming new front and rear floor molds and fabricating new widebody quarters, doors, fenders and front nose. Once the body plug was complete, the long hours and tedious work began. First, molds were built, then parts made and then these were assembled around and onto the reconstructed birdcage. With the body completed, the next decision was color. Discussion entailed every color of the rainbow when green was settled on. PJ Burchett mixed several spray-outs for Van to choose from. Axalta Hot Hues candy green was a starting point, then a multitude of pearls were blended into the mix to create Vanguard Green.
Under the 427 Corvette Stinger hood lies a 427-inch 2018 LS7 mated to a TCI 6x six-speed paddle-shifted automatic overdrive transmission. A Vintage Air Front Runner serpentine system drives a high-amp alternator charging an XS Power AGM battery and a Sanden compressor pumping R134a refrigerant to Vintage Air air-conditioning.
Street Shop stainless steel fuel lines feed an LS Classic twin throttle body fuel-injection system supplied from a Rock Valley gas tank fitted with an Aeromotive internal fuel pump. B Rod commissioned Dan Dittberner Engineering to develop the CAD data to make a breather top and fuel rails. In keeping with the look of a 427 Corvette Tri-power air cleaner, B Rod handformed a set of coil covers with the look of big-block Rat valve covers. The cooling system consists of a DeWitts radiator and DeWitts twin electric fan shroud assembly.
As illustrated by Eric Brockmeyer, the rich tan leather interior by Steve Holcomb’s Pro Auto Interiors relies on custom fiberglass bucket seat pods by B Rod for shape and Dynamat to suppress heat and road noise. The sound system features an Antique Auto head unit with Rockford Fosgate speakers and amplifiers. Instrumentation is by Classic Instruments. The completion of Van’s 1967 Corvette Sting Ray Wide Body by B Rod took three years to the month, making its 2019 SEMA debut a massive success. Vette

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.

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:
Halo model will also be the first-ever AWD Corvette
Back in August, we exclusively reported the upcoming mid-engine Chevrolet Corvette Z06 would feature a twin-turbo flat-plane-crank dual-overhead-cam V-8 based on the C8.R race car’s engine. Now, we can report from an even higher-placed source that the range-topping C8 Corvette ZR1 will add a performance hybrid system to boost it to 900 hp.
Rumors of a hybridized C8 have been flowing for quite some time, but now we have exclusive confirmation from a senior official at GM. The ZR1 will build on the Z06’s all-new engine with a performance- (not fuel economy-) oriented hybrid system to fill in torque gaps and increase total output to an even 900 hp.
Our source wouldn’t elaborate on the engineering details, so we’re still unclear whether street cars will share the C8.R’s 5.5-liter displacement, which is unusually large for a flat-plane engine and would likely vibrate too much for customers’ liking. Past rumors have suggested displacement ranging from 4.2 liters to 5.5 liters.
At a minimum, a hybrid system would sandwich an electric motor between the engine and transmission to bolster output. We’ve heard previously, though, the somewhat small frunk in the base C8 Stingray is protecting space for a pair of front-mounted electric motors which can both increase performance and, more critically, perform active torque vectoring to complement the rear axle’s electronically controlled limited-slip differential. This first-of-a-kind all-wheel-drive ZR1 could see major benefits in handling and the ability to put down power while exiting corners. This is a strategy that’s been employed to great effect on other hybrid supercars like the Porsche 918 Spyder.
Naturally, electric motors, a battery pack, inverters, and wiring will add substantial weight to the car, which is why it all needs to add enough power to balance things out. The big question is where Chevrolet will place the battery, which it will want to mount as low as possible to keep a low center of gravity. Other mid-engine hybrids mount it in the firewall between the engine and the seats. It’s also possible it could be mounted in the bottom of the frunk or trunk, depending on how large it is. We expect it will be fairly small as it just needs to hold enough juice to boost the engine under hard acceleration. While some mid-engine hybrids have the ability to drive under pure electric power for short distances to meet emissions regulations in some countries and cities, we doubt this was a major concern for the Corvette team. Like the Ferrari LaFerrari, we think the ZR1 will be entirely concerned with performance, not efficiency.
Separately, our source corrected our previous speculation that the Z06, C8.R, and ZR1’s DOHC engine would share design and engineering with the Cadillac 4.2-liter Blackwing V-8. Despite declarations from top GM and Cadillac brass the Blackwing is exclusive to Cadillac, we figured there would be some shared engineering resources to save money. That’s not the case, our source says. Years ago, under a previous product plan that’s since been whittled down, Cadillac was promised an exclusive engine and got it, so GM gave Cadillac and Chevrolet separate pots of money to design two different DOHC V-8s simultaneously.

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.

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.
