It’s been quiet on the Corvette front as of recent, but what is believed to be the 2018 C7 Corvette ZR1 has been spotted once again, this time at the race track.
Specifically, four prototypes were present at Mazda Raceway Laguna Seca, as the Corvette ZR1 tackled the infamous corkscrew corner. Corvette Blogger first reported on the sighting, and the individual who shot the video above says the Corvette ZR1 prototype sounded quite different than the 2018 Chevrolet Camaro ZL1 1LE that was also present.
Two Corvette prototypes featured the big wing we’ve seen in the past, but the other two were sans wing as they ripped around the track making thunderous noises.
The 2018 C7 Corvette ZR1 will supposedly usher in a 6.2-liter DOHC LT5 V8 engine, per leaked GM documents, but we have a hard time truly distinguishing between the prototype Corvette’s exhaust and the 6.2-liter LT4 supercharged V8 the Camaro ZL1 1LE is running. The video above loops both vehicles as they accelerate out of the corkscrew to try and pin a difference.
The individual who captured the video also says the ZR1 seemed to be considerably quicker than the Camaro ZL1 1LE and mentioned a 750 hp figure per a reliable source.
We still have to take every ounce of information surrounding this prototype with a grain of salt, as nothing is certain until Chevrolet and the Corvette team want the world to know. Until then, we’ll have to patiently wait for some solid intel.

You really notice the corvette’s acceleration compared to the ZL1 out of that corner.
This car should put up some serious numbers and I wouldn’t be surprised that it takes some track crowns from a lot of super cars
There is no supercharger whine coming from the Corvette. Is that the Mercury Marine engine?
4-cam 32v

In a 6.2 version?
@bob
Yeah I noticed that too, you can clearly hear the S/C w/ the ZL1 runs at the end but not w/ the Vette,
Well maybe you can kinda hear a very faint S/C whine @ around 00:14? Or maybe it’s my ears playing tricks on me.
I hope it is the N/A engine.
Sil,
I listened again and there is no blower there. It might be the different sound of the twin cam engine. It sound like it means business. Lol
@ Bob
Maybe it’s just my mind. It does sound good.
It does have a blower on it. It’s a very loud DOHC in which overpowers the whine. Plus the ZL1 and ZR1 videos are at different angles, different acoustics. I’ve seen a clip of it pulling on Laguna Seca and you can clearly hear a deeper sounding blower whine.
That second corvette sounded like pure evil was lurking under that hood. There was no supercharger, that was an engine and a monstrous beast of a v8 engine at that.
Gm is building it’s own DOHC engine’s, in house. Corvette will have it’s own, and Cadillac will have it’s own to.
