What does this sound like to you?

Sounds like a Ferrari V8 with a flat plane crankshaft.

I'd be really, really surprised if it is a flat-plane crankshaft. At 5.5L, how will it pass the NVH requirements? The ford FPC engine is 5.0L, and I think a 93mm stroke. It's possible, but my bet is no.

Todd,

U may of course be right, but like Phil, it sure does sound like a Ferrari. Perhaps its a bit of one-upmanship by GM to say they’re in the game. Of course, that could also be a 4.2L.

This I found in the FPC collection (YouTube). FPC? IDK, but see if the interior doesn't look familiar!

Steering wheel certainly looks familiar.

Doesn't sound like my 355

I think that's the C8.R in testing not the production car.

Jalopnik has video footage of the production mid-engine car at the 'ring. Sounds like a 6.2 V8 to me.

The ford voodoo motor is a 5.2L.

While I will wait so to see the final product, based on the Jelopnick and Autoweek photos, I find the body design of the C8 to be underwhelming at best. It seems to be a generic mid-engine design devoid of any originality. While it does have a hint of the “Corvette” look to it, I really hope the final product is better.

Like the C4 made a dramatic design entrance, so shall the C8 if it becomes a Corvette as a mid-engine design. I wasn’t thrilled with the C5-C7 until the ZR1 version cam out. Just my personal taste.

Rumor mill I've heard is there will be some carryovers from current C7 generation ie 6.2 supercharged, and a very special DOHC with forced induction pushing far north of current C7 ZR1 levels. No idea on internals if we're talking 180 degree crank, Titanium alloys etc. I hope the LS7/LS9 will not be the last factory motors with Ti con-rods.



I hope it goes on a diet and closer to C6Z/ZR1 weight levels.

Whatever that motor was, it sounds like it is both DOHC and smaller displacement than the typical Corvette. I wouldn't be surprised if it is a supercharged or turbo V6.

While at BG earlier this year I spoke to a GM engineer who worked on the C8 project (I will leave it at that). He said the C8 will definitely get DOHC V8 engine specifically designed for it. Not a derivative of any other current GM engine. It will come in both NA and turbo version but probably not at launch. He also confirmed there would be hybrid version down the road. BTW he owns a C4 Z.

Now, there's a juicy little tidbit.
