That is most certainly a small displacement TT V8. Listen to a 488GTB with an exhaust for comparison or even a Mclaren. The engine has been basically revealed already via Cadillac. 4.2L “hot v” configuration.

IMSA rules call for 4.2 FI or 5.5 N/A. I’m thinking we heard, if it really is the C8.R, a 4.2 TT V8 similar to what Cadillac has out right now.

For certain it doesn’t have the thunder of the previous .R versions but it sure does sound similar to the Ferraris in GTE

"While not yet officially confirmed by GM, it appears the race car features a twin-turbo V8 powerplant"

V6, or V8?
I know gm has been working on a mid engine TT v6 for the Corvette for a while now(caddy will get a less hp/tq version 1st)Less weight and a better weight balance. I highly dought youll see a TT V8 in the production car. Maybe just a TT v8 in there race car.

GM already has a TT V6. See the ATS-V and CTS - V Sport. 3.6l direct injected. Its been in production for a few years now.

At this point, I’m pretty sure it’s mid engine GT500.

A tt v6 Corvette would cause a great disturbance on the internet. A million vaginas all simultaneously filling with sand.

Correct but the Corvette will have a slightly modified version of that caddy engine.

Do you have a link for this? I find it hard to believe GM developed a brand new engine and is not putting it in their flagship model particularly after switching to a mid engine platform.

Edit.....

Unless your talking about a cheap base model which I wouldn’t put past GM. All the leaked videos of the C8 are a small TT V8 though.

Nope, there are all kinds of info floating around currently.

Definitely doesn't sound like a V8. Then again, neither does the McLaren 720S.
