The marketplace, and the technology, are evolving. Remember, the Corvette started with a straight six, grew into a small block V8, and went through variations of carbs and fuel injection all before the big block. The contemporary iteration that most of you are driving will soon be as antiquated as that Blue Flame Six.

Yes, we will probbaly see auxiliary electronic motors in a later version of the C8, and eventually a fully electric Corvette, but it will be because of the market place and latest technology not the government. It’s just Darwinism, folks.

You may have missed that the front fender of the C8R is also wider and has a vent that makes it look more aggressive while the road car's front fenders are narrower and plain. The rear diffuser is also very aggressive while the road version is very tamed. I'm hoping the road version will be very close to the C8R because if you are going ME, might as well go all out exotic. These seemingly minor differences amount to a whole different feel. Everyone sees styling differently and this is just my opinion, I don't expect you to agree.

i do agree. The c8R is an exaggerated version of the c8 but they do look very similar. The c8 IMO is supposed to retain the feel of Corvette. IMO it will look like a more angular and aggressive mid engine platform C7.

Very impressive looking Vette, but the sound is different.

****. I'm embarrassed. I cannot identify that thing by the sound. Clearly loves to rev, so not the Mark IV big block I'm used to. Neither a typical small block Chevy.

It's different. Jarring to an old street drag racer. But I gotta tell you. It's impressive as all hell. Sounds like it could wind out forever.

That was flukey.
Take a look at previous seasons (2016-7)...
Maybe not as bulletproof as the C7.R, but they have done well nonetheless.
They had it racing well before the GT started production. Pratt and Miller doesn’t want that to happen with the C8.R, and it won’t.
Why?
Expect to see the full thing in race livery at Le Mans, but it won’t race until the Rolex 24 in 2020.
If that is true, then Chevrolet is conceding the 2019 season championship and that would be something unprecedented in Corvette Racing's 20 year history.

Doubt the street version will have this... and this was probably pointed out before (it's visible on the day shots too)... but I just noticed what appears to be a intake on top of the rear deck.

Didn't see anyone post this but to me there's a discernible difference between the 8R and what most think will be the production as far as engine sound goes, and the production sound is a little deeper.

That's not true at all. IMSA and FIA BOP adjustments keep things relatively equal every year. However, the net effect of that is the least capable car drags the rest of the field down to their level. That's one of the problems Ford's been facing w/ the FGT. The biggest culprit in slowing everyone else down is BMW which has been consistently slower than everyone else for several years now.

I don't think we're necessarily seeing the C8R in the Sebring video. I think we're seeing essentially a street car that has some modifications including a racing engine, wing, and a few other tweaks. Pratt and Miller has more than a year before the first race to lock in the C8R configuration.

Obviously, the street car won't sound anything close to that, and neither does the C7R sound anything like the street car.

That's not at all an accurate account of FGT's first year (2016).

Ford had technical (mostly electronics) issues in the 2016 FGT intro year very early, in the first race at Daytona, and second at Sebring. They quickly sorted it out, and became very dominant, putting together a string of IMSA wins. They finished 1,3, & 4 at the 2016 24 Hours of Le Mans, 5 months after their first race, and they had already won in IMSA before that. All 4 cars were running at full speed at the end of 24 hours.

Shortly after, IMSA BOP dialed them back a lot and C7R did win the IMSA manufacturer's championship. However, that wasn't because of reliability as much as it was the fact that the FGT was significantly slowed primarily by limiting boost and adding weight, but they finished 2nd.

Of course they sound different. One is a racecar and the other is not.

It's the same case with the Ford GT, the racing version sounds totally different than the road going version but they have the same engine. The difference is that the c8 has a V8 for sure

They're not the same engine, but the racing engines are derived from the street engine, which is what FIA and IMSA GTLM rules require.

In the case of the ME, there will almost certainly be multiple engines used in various versions, and the C8R will only have to be derived from one of those engines.

Sorry my point in the above post was wasn't very clear.
I was referring to the reg where, IIRC, IMSA throws out any points earned previously during the season when a new car is introduced.
IOW, any points earned previous to Le Mans are dumped and, essentially, Corvette Racing's season truly begins there, which is why manufacturers introduce new cars at the beginning of seasons not midway thru.
At least that's the way I remember it.

Gotta disagree on that one...
I believe the car at Sebring truly is the C8.R that will be raced by the boys & girls at C.R. next year.

Obviously, the street car won't sound anything close to that, and neither does the C7R sound anything like the street car.
True, but it sure sounds good anyway.

Ford had technical (mostly electronics) issues in the 2016 FGT intro year very early, in the first race at Daytona, and second at Sebring.

In my opinion, I think we are basically seeing the C8. I assume (and hope) that the side scoop profile is the same. Just from past generation similarities between the street version and .R version. I still believe the ring photos a couple months ago were still full of padding and disguise from the real thing. Sucks we still have to wait till New York most likely. But I think the C8.R profile will be almost identical to the street C8, besides the stance. You guys think the same?

Salem, you are correct on the above. Once they start the IMSA season, which happens exactly 7 weeks from today (1/26/19), they are pretty much locked in to campaigning the same car. They wouldn't be forfeiting C7R points, but they'd have to keep racing it to compile additional points. I don't think they have the sponsorship money or infrastructure to campaign both the C7R and new C8R, when it's ready.

There is some thought that they may try to do some testing of the C8R in some of the WEC events in the fall of 2019. That would keep the C7R IMSA season intact.

On the C8R, it's way too early to have locked in the final configuration. There's a lot of tweaking and design work to do, and Pratt & Miller (AKA "Corvette Racing") has a long way to go. The process is to start testing with something very close to the production car, and then start modifying what they need to modify to get to something competitive in the GTLM class and compliant with all the rules.

Yes
I LOVE the C8R. The camo cars testing in germany - they are okay but nothing I would go out of my way to spend money on. Kind of odd I get such a different reaction to the cars. Blow my mind GM, were ALL waiting....

it’s a v6.... with turbos..... I had a feeling that’s what it would sound like. Chevy is following the trend... nsx.... v6 turbo, Ford gt...v6 turbo. The ford gt was designed to win the class, that’s why it has a v6. The 5.5 l v8 in the c7r was limited like crazy to meet racing class rules.... the rules give advantages to v6 motors... the c8r has a v6....look, go to YouTube and and watch clips of the IMSA nsx and gt.... they sound the same.

Under current IMSA GTLM rules, you have to be under 6L to run naturally aspirated, and under 4L to run with forced induction. They could downsize the Cadillac 4.2TT V8 but to homologate that would have to be offered in a C8 production car.
