Chevy's new super-Vette was caught testing in Colorado.
The next Chevrolet Corvette Z06 has been a long time coming, with spy videos dating all the way back to January of this year. Things fell quiet for some months as the coronavirus pandemic forced GM to press pause on a number of vehicle development programs.
Now, the next-generation Z06 is back in the news. Last month, a new spy video revealed the new super-Vette accelerating hard on public roads. More recently, someone published a video to Facebook in which they got up-close to a prototype Z06 idling on the side of the road.
The video was posted to the C8 Corvette Owners (And Friends) Facebook page and it shows a C8 wearing camouflage and plain black cladding while testing somewhere in Colorado. The state is popular for high-altitude testing among US automakers thanks to its mountainous terrain.
In sharing the video, Dylon DeBaca said he believed the driver was "waiting for computer or diagnostic system/something to reset before he pulled off again," meaning we don't get a chance to hear more than a faint whiff of exhaust noise. We do, however, get a chance to look at the placement of the car's exhaust tips, which is how we know that it's something other than an ordinary LT2-powered Corvette.
The forthcoming Corvette C8 Z06 is expected to pack something very special behind the seats: a racing-bred 5.5-liter V8 with a flat-plane crankshaft and dual overhead camshafts per bank. That's never been officially confirmed, but it's noteworthy that this prototype lacks the typical American cross-plane V8 burble at idle, and features unique exhaust tip placement, with all four tips crowded around the center of the rear fascia instead of being split up, one pair on either side.
Why switch to a flat-plane crankshaft? Because the lighter crank design and more even intake and exhaust pulses help improve rev-ability, as well as high-RPM breathing. The LT6 that will power the next Corvette Z06 is expected to spin as high as 9,000 rpm and produce 600+ horsepower, giving the blue-collar supercar one heck of a racy character. We can hardly wait.
