It sure seems like Chevrolet is putting the flat-plane crank, dual-overhead cam engine from the Corvette C8.R race car in the mid-engine Corvette Z06. We just received spy video of a C8 Corvette prototype doing some launch control runs at a GM test track, and—aside from being very quick—our first impression is that this Corvette sounds a lot like a Ferrari 458.
It’s quite a different noise from the pushrod, 6.2-liter small-block that powers the C8 Stingray, as a flat-plane V-8 has a different firing order from a traditional cross-plane layout. It sounds a bit like two four-cylinders blaring at each other. This is the classic Ferrari V-8 noise, shared with everything from the original 308 of the mid-Seventies to today’s F8 Tributo.
Last month, we heard a rumor that, unlike with the previous Z06, Chevy is opting for natural aspiration with the new one. One Australian publication reported that the Z06 will make 617 hp from a naturally aspirated 5.5-liter V-8—believable, given the displacement, and similar to what Ferrari squeezed out of the 458’s 4.5-liter mill. That would be less power than the old Z06, but with a sound like this and mid-engine handling, it’s hard to imagine anyone complaining.
