Video footage of a camouflaged C8 Corvette has been released by ***********.com showing what sounds like a flat-plane crank V8 revving.

The video shows a car on the street, so it's hard to know exactly what it has under the hood, but rumors have long persisted that a higher-performance 'Vette would feature the higher-revving engine.

Commenters pointed to the higher pitch of the engine and the smoother revving, signs that this is not a traditional cross-plane crank V8, as has been standard for the Corvette for most of its life.

The video raised suspsicions among commenters that this might be the Z06 version of the C8. And that seems like a reasonable suspicion, given the timeline of Corvette releases.

Car and Driver reports that the Z06 will feature a naturally aspirated flat-plane crank V8 making more than 600 hp, while the ZR1 is expected to turbocharge that number to around 800 hp.

An electrified version is also expected and rumors have its power figure rising all the way up to the four-figure mark.
