Chevrolet Corvette C6

HPDE Overview

The C6 Corvette improved on the C5 in every measurable dimension. The LS3 makes 430 hp, the Z06 LS7 produces a staggering 505 hp from a flat-plane-crank 7.0L V8 that revs to 7,000 RPM. The chassis is stiffer, the brakes are larger, and the suspension geometry has been refined. The C6 Z06 weighs just 3,132 lbs thanks to an aluminum frame, carbon fiber fenders, and a titanium exhaust — it is the lightweight LS V8 weapon. On track, the C6 Z06 is in a different league from the C5. The LS7 engine sounds like nothing else on Earth — a deep, mechanical growl that builds to a roar at 7,000 RPM. The car puts power down with confidence thanks to the limited-slip differential, and the magnetic ride suspension (on Grand Sport and later models) adapts to track conditions in real time. The C6 Grand Sport is arguably the sweet spot — it gets the wider Z06 body, bigger brakes, and magnetic ride without the high-strung LS7. The C6 Z06's LS7 has a well-documented valve guide failure issue that can destroy the engine. This must be addressed before track use.
