The C8 Corvette may have been unveiled almost half a year ago at this point, but it continues to be one of the greatest points of interest in the world of automotive enthusiasm. The Corvette faithful have turned their attention to the upcoming high-performance variants of the Corvette, and thanks to a newly uploaded Facebook video, we now have apparent confirmation about one of the primary features of the C8 Corvette Z06.
Facebook user Jim Lill recently uploaded a video to a C8 Owners group on the platform that shows a heavily camouflaged car testing in the canyons roads east of San Diego. While we are used to seeing these tarted up Corvettes at this point, we have yet to hear one with an exhaust note quite like this. As the blacked out Z06 development car rounds a corner in the clip, it becomes clear that something is missing: the grumbly burble of an old school pushrod V8.
Instead onlookers are hit with something that sounds more like a Ferrari than a Chevy, thanks to a flat-plane crank V8 hiding behind the driver. We have reported for quite some time here at MC&T that the C8 Corvette Z06 would carry a naturally aspirated DOHC flat-planer, specifically one derived from the C8.R’s 5.5L V8 engine. Back in early October when the C8.R debuted, we doubled down on this, stating that FIA rules mandate that 300 copies of an engine found in a race car must be produced for a road-going version of that car in order for it to be legal for competition. This Facebook video acts as further proof that Chevrolet is fitting the Corvette Z06 with this homologated engine.
In IMSA compliant spec, the 5.5L naturally-aspirated V8 engine produces 500 horsepower and 480 pound feet of torque, though we expect the roadgoing C8 Z06 to be quite a bit more powerful than that. While we will always love a pushrod V8 engine and the sounds that come with it, the C8 is a new type of Corvette and it deserves a new type of engine layout.
