10/15/19 SURPRISE C&D Published their test TODAY!
Someone at Car & Driver looked at their calendar wrong. Today is NOT Wednesday but they published their Review today. 0-60 in 2.8 seconds (Z-51, MR Suspension). 1.1 seconds faster than the manual trans C7 Z51. However, the C8 weight gain added 10 ft to the 70-0 stop at 149ft. C&D's biggest complaint: It's a bit too refined in Tour mode around town where it rides like a sedan and it's not as loud and steering is not as twtichy fast as a 911 (seems like the remedy to that is one notch up the 6 driving modes?). The Quarter is gone in 11.2 @ 122 MPH (C7 Z51 = 11.7 @ 119).
C&D had this car for a week and ran it at Gattan Raceway against a C7 Z51..."the C8 turned a best lap of 1:26.1, the C7 a 1:27.0. A roughly one-second difference might not sound like much, but consider that after just a half-dozen laps, the C8 would cross the finish line as the C7 pulls onto Grattan’s straight. ...the C8 braked later into several corners and accelerated harder." The C8 pull more Gs in every curve and corner - as we would expect. "But such close lap times don’t remotely convey how much easier it is to go fast in the C8. It cuts more cleanly into turns, and its rear tires are more planted exiting them; the C7’s tail is nervous and twitchy by comparison."
The faster you go, the better the C8 feels. The steering cuts like a race car's, and the cornering limits are virtually out of reach on the street....For a base car with the Z51 package and FE4 dampers, you're looking at only $66,890. This is nothing less than the democratization of the exotic car.....Extensive acoustic insulation has made the C8 not only quieter by three decibels at 70 mph than the C7, but just plain quiet. This kind of dynamic bandwidth is almost unheard of in the mid-engine exotic realm.....Overall, this is by far the best Corvette interior ever.....After all that poking and prodding, we have concluded that the new C8 is spectacular, amazing, and supremely capable. Maybe even revolutionary.
10/14/19 We will see Car Rag First Drive Reviews Wednesday
Motor Trend and Car & Driver (at least) will publish public road tests and (at least) a C7 Z51 vs. C8 Z51 side by side track test at Grattan Raceway's road-racing circuit (C&D). Both magazines got air with their C8s. Both have agreed that they cannot publish any specifics until Wednesday. Motor Trend ran on a closed Ca road. The jump was made in "Tour" mode. Upon returning the Red C8 to GM, MT told them about the jump. GM's response, "Only Tour mode? Why not "Sport" and "Track" modes too?" Here is a quote from the MT jump:
10/13/19 The C8 Makes its First Ever Petit Le Mans Appearance
The whole thing was surprisingly mundane," Trajano said. "All I could hear was tire noise in the run up to the jump. The jump itself was almost serene because of the momentary break in between tires touching the road. Landing was smooth as butter, like it was made for that jump. Could've used more speed for sure." Photographers always say that.
Long time Corvette Racing driver Tommy Milner piloted a new Chevrolet Corvette C8.R (#4) for a couple of "demo laps" prior to the start of the Motul Petit Le Mans at Michelin Raceway Road Atlanta.
10/10/19 Today's C8 headline: We know all about the C8.R engine
GM has confirmed that the racer WILL run a 5.5 Liter, DOHC, Flat Plane, NORMALLY Aspirated V8 with 500 HP and 480 pound-feet of torque. Yep, 10 HP more and 10 pound-feet more than the production LT2....but much higher revving. Pratt & Miller (Corvette Racing engineering) has apparently decided they prefer the combination of [more Normally Asperated Cubic Inches] versus [fewer turbo charged Cubic Inches] - the latter worked well for the Ford GT so we are surprised by this configuration considering the Le Mans more lenient rules for smaller Turbo charged engines.
As we told you in the past, GT Le Mans homologation rules require that at least 300 production version engines must be built, so this confirms that the Z06 will offer a version of this engine. BUT it need not be NA. It could have Turbos. Let's get real. We've seen them. It WILL have two outboard turbos to probably produce at 675-700HP (the C7 supercharged LT4 = 650HP). The 5.5 liter engine of the Corvette C7.R produces 491 horsepower at 6,000 RPM so like the C7 Z06, the C8 Z06 will provide considerably more HP than the race car is allowed to have under the rules.
10/09/19 Motor Trend says NEXT WEEK!
MT is saying that next week they will be publishing a comprehensive test of the C8. C&D and R&T won't be far behind. We've seen indications that R&T's testing might be a comparo. This is about to get really interesting. CAUTION! Although the cars the car rags will be testing are "Production Spec" we need to realize that they are NOT production cars to the best of our current knowledge. Looking forward to hear from the editors if the tested cars are more of the hand assembled cars we've seen at dealers or if they are pilot cars off the assembly line. I don't think they would put pilot cars into the hands of industry testers, but maybe we'll find out next week.
10/7/19 The Detroit Free Press is claiming the UAW strike is a severe hit to the Production Schedule
Contrary to some reports we have already received, the DFP claims that BG still hasn’t finished production of the C7 and after the strike is settled, they must finish that up before changing the tooling over to C8 production. Back in June Barrett-Jackson sold the last C7 Corvette that WOULD be produced for $2.7 million. I have NOT been able to find anything confirming the delivery of that purchased C7 (a Black Z06), but the final orders for SOLD C7s were terminated on 7/18/19 (C8 debut date). The UAW strike started almost 2 months after that on 9/15/19.
In the past the DFP has had a reputation of being pretty reliable. Here are some facts: Bowling Green has had the capability of producing two different Generations of Corvettes on the same assembly line since they were producing some C6's during the C5 final model year. BTW, GM's Aussie Holden factory pioneered this technic and it has spread to other selective GM plants. Regardless, if there are more C7s that MUST be produced, this would NOT STOP the conversion of much of the assembly line over to C8 production while the strike is taking place. Obviously, the total production volume would NOT be C8 for however long it takes to wrap up the C7 production. Also, GM could approach those pre-sold C7 buyers about changing their orders to C8 with some incentives - or not.
BOTTOM LINE - the biggest C8 production time delay issue is the strike itself. Once the strike is over, GM has TWO Shifts of BG workers ready to start rolling the cars out of the plant. The upside? You can bet that Tadge still has teams out there real world testing C8s looking for any possible needed tweaks to the mountain of algorithms helping you drive the C8.
10/6/19 Why should we care about the C8.R except for bragging rights if it wins?
The Le Mans race GTE class homologation rules that the Corvette C8.R must follow, state that the “engine must be derived from a series production engine produced at more than 300 units and fitted to a series vehicle from the same manufacturer.” This means that the C8.R engine will be used, or directly derived from, a Corvette C8 production engine. The Z06 is the obvious candidate for the production version of the engine.
The 100% consensus of the 'Automotive Knowledgeable' at the Vert/C8.R reveal who heard the racer revving, state without a doubt, that it is NOT an LT2 engine. The overwhelming opinion is that the quick, high revving, LOUD engine they heard reminds one of a Ferrari engine (Flat Plane, DOHC) much more than the 5.5L OHV V8 that has powered the C6.R and the C7.R. Also interesting is that no one has mentioned anything about hearing any Turbo sound at the reveal. IF THERE ARE NOT TURBOS, then the displacement MUST be 5.5 liters to be competitive. We have been told that the new DOHC engine would be based on the Cad Blackwing but always in the same sentence it is made clear it will NOT BE the Blackwing. Separately, an engineer has stated that the 4.2L Blackwing block cannot be punched out to 5.5 L. Add to that, the Blackwing has twin turbos mounted INBOARD, between the V of the V8 which makes the heads VERY UNIQUE.
We have posted the CAD drawing of the C8 DOHC V8 with outboard twin turbos in the past (again below) but we don't know if that engine will be in the Z06, ZR1 or another model (Zora?). The Blackwing heads would NOT appear to be adaptable to outboard turbos so it is extremely unclear how the Blackwing could contribute in any way at all to the C8 engine unless the CAD drawings are of an abandoned project which would beg the question; why leak a CAD of an abandoned project?
So today's educated guess/compilation of facts is that the C8 Z06 and C8.R racer (sing a shorter stroke version) will likely share engine designs of Flat Plane DOHC V8 that is surprisingly normally aspirated. If NA, the displacement MUST be 5.5L if they have any hope of winning GTE.

10/5/19 In Depth Video on Infotainment System
The C8 Tour comes to Vlogging Sales guy's dealership and he takes us through the Infotainment screen choices in the dash. It's a quick tour and he loses camera focus a couple of times but it IS informative and impressive, IMO.
10/03/19 Hear the 'Mystery' C8.R Engine
What do YOU hear? Does that just sound like last year's OHV engine to you? It certainly doesn't have the F1 high revving loud sewing machine sounds, nor that of one of their street versions like a Ferrari. Sounds a bit more cranky (pun intended). Le Mans rules are more generous for turbo engines and the hot rumors are that the Z06 will have a flat plain DOHC TT engine, a version of which could make it into the C8.R. Notice that the rear window glass has been blacked out = no view of the engine. Intriguing.
Please look BELOW the immediately following Vert data to see the reveal of the C8.R that will have its debut at Daytona in January.
10/02/19 NCM Site shows C8 Vert
- The Convertible will be priced $7,500 higher than the 1LT coupe.
- The Top stores horizontally in a compartment above the engine.
- The mid-engine 2020 Corvette Stingray was engineered first and foremost as a convertible.
- It weighs 3,637 lbs; 102 more than the Stingray; 60 more than the Z51.
- The hardtop stows seamlessly into the body, maintaining the Frunk and the trunk even with the top down.
- The nacelles help reduce air recirculation into the cabin.
- The tonneau also provides a rear power-adjustable window and a vent for mid-engine cooling.
- The two-piece top can be activated at speeds up to 30 mph and retract in as few as 16 seconds.
Powered by six electric motors and uses encoders for precise control..
- A body-colored roof is standard, while Carbon Flash metallic-painted nacelles and roof are optional.
- The sheet-molded composite top stows in a compartment made from lightweight composite panels and heat shields to manage heat from the engine.
- A divider glass window in the middle of the vehicle can be power adjusted with the top up or down.
- The glass has been optimized to reduce air recirculation and wind noise in the cabin for improved quietness.
- The same rear spoiler used on the Stingray coupe’s Z51 Performance Package, results in identical drag between the coupe and convertible with the top up.
- The chassis springs and dampers have been tuned specifically to provide nearly the same performance as the coupe.
- The drive train is the same as that in the Coupe
Short Video - includes top being raised while moving
Long Video of the Reveal at Cape Canaveral
10/02/19 The C8.R revealed
NO announcement about the engine powering the C8.R was made.
There will be two C8.R debuting at Daytona in January.
One car will wear the colors you see and the other will wear the more traditional Yellow and Black colors.
You might recall that we reported to you a month+ ago that we observed what appears to be a dynamic wing on the C8.R Prototype. Here's a closeup of it. Notice the long slot that enables the wing angle to be altered via electric motor(s?). Full forward is probably a vertical as possible for stopping.
Lots of pics of the C8.R:
10/01/19 C8 Vert Debuts Tomorrow
What do we know? Nothing new so we will have lots to post tomorrow after the reveal. To recap what we already know:
The Vert will weigh in at 3,637 lbs, 102 more than the Stingray and 60 more than the Z51.
The Folding hardtop power button is near the power window buttons on the driver's door panel.
All of the rest we know can be seen in the following pics:
9/30/19 Listen and watch as a 'passenger' as Road and Track runs a C8 around Thunderhill Raceway (Nor. Cal.)
As part of the R&T Performance Car of the Year testing, the following video was shot as a promo. Good opportunity to hear the engine and the shifts. Enjoy the sweet sounds.
Also, during the testing, they messed around a bit. Two different editors, one 5' 9" and the other 6"1' managed to fit themselves into the rear trunk (NOT at the same time). So two sets of golf clubs or one R&T Editor can fit in the trunk.
Also; The frame is STIFF. The C8 can be parked on undulating terrain so that one tire is a few inches up in the air.
09/29/2019 C8 Hybrid Prototype spotted
As you see, the Hybrids still wear cammo, but the big red plug resting on the passenger front fender is not good at keeping secrets.
Realize that the hybrid is the rumored 1,000 HP model. Notice that the edges of the fenders do not look like they have the vertical flat terminations that we have seen on the C8 Stingrays. They look 'extended' like flairs. Wide body?

09/27/19 Praise from future Owner about GM Order Service
For those who place orders, I'm sure that service can vary from one Dealership to another, but the following was posted on Facebook from someone who is experiencing a very positive information flow"
09/25/19 No News but be assured we will post it here when it comes
I wanted to let everyone know how absolutely impressed I am with communication with Chevrolet on ordering this vehicle. They have a concierge service that is far and away one of the best I’ve ever dealt with when ordering a vehicle. I have ordered Ferraris, Lamborghinis, Aston Martins, Maseratis and Porsches and have never gotten this type of immediate response and knowledge about intricacies with the vehicle. If you have any questions I suggest reaching out to them, they can definitely answer anything. If they don’t know they send Harlan an email and he gets right back to them so they can get back to you.
One guy is claiming there will be a 4th seat option in 2021, but that's about it. Not confirmed, by the way.
09/23/2019 North American Car of the Year Finalist
The North American Car of the Year award is presented to the finest automotive product produced for a given model year, each year. There are 3 separate categories; passenger cars, utility vehicles, and trucks. The winners are usually announced at the North American International Auto Show in Detroit. The winners are selected by 50 respected jurors from print, online, radio and broadcast Automotive media across the U.S. and Canada. GM has two models vying for the award; The Corvette C8 and the Cadillac CT5. Historically the NAIAS has been held in January in Detroit but beginning in 2020, the NAIAS moves to June in Detroit. At this point in time, THAT is when the NA COTY will be announced.
09/20/19 Resource Reminder
We seem to have entered a lull in the new information 'leaks.' It might start up again as we get closer to the C8 Vert reveal. In the meantime, about 7 weeks+ ago we told you about a series of GM Engineer produced SHORT videos explaining details about the C8. Selecting the link below will take you to a You Tube index of 23 SHORT videos that are told in first person by engineers and GM personnel. Quite informative and professionally presented. Hope you can find the time to view them:
09/20/19 UNCONFIRMED RUMOR - C8 Vert
With the official GM C8 Convertible Reveal scheduled for October 3, a rumor that Convertible Production will start on February 10 is spreading across multiple sites on the internet.
Seems a bit odd. The last communication regarding C8 orders we heard was that the first phase of production (January - March or as long as May) was almost sold out. This rumor states that the Convertible, for which there are zero orders at this point, will start roughly 6 weeks into the first phase of production. Seems like we are missing some pretty key information if this rumor is true.
1) Was there always a block of the first phase of C8 production designated to be Convertibles?
2) Is BG increasing production volumes to accommodate new, expected Vert orders?
GM has repeatedly surprised us in the past so we will find out the FACTS in a few weeks.
9/19/19 Production Constraints
Below is a link to a Vlog from a Vette Sales guy providing the production constraint information as of today. Since Production is not currently taking place, these 'constraint announcements' would seam to telling us that they have built inventories for the options that are NOT ON CONSTRAINT.
09/18/2019 UAW strike impact on the C8 -updated
- GM Authority is reporting that they think the first C8 deliveries will not be impacted by the strike.
Short answer: Short Term; Yes. Bowling Green UAW workers ARE currently picketing the plant and no cars are coming off the assembly line. At a minimum, worker participation/training in the spool up of the C8 are suspended. Not only is the product (the C8) new, almost half of the workers are new to BG hired for a second shift of C8 building. Announced intentions indicate the production line will begin MUCH slower than normal to assure the highest quality is maintained.
The final C7 rolled out of the BG Plant on 7/28/19. GM poured $773Million into almost doubling the size of BG since 2017. GM announced that the Cadillac DOHC TT V8 Blackwing will be assembled at the Performance Center at BG and rumor has it that the LT2 and all of the C8 engines will also be assembled there.
