Chevrolet Corvette Z06: racing genes, wide body and new naturally aspirated V8

3

General Motors has fully unveiled the most powerful version of the Chevrolet Corvette Z06 mid-engined supercar to date. Its 5.5-liter LT6 V8 engine develops a maximum power of 679 hp and 623 Nm. Sales will begin in the second half of next year.

The base eighth-generation Corvette Stingray debuted in the summer of 2019 – the supercar changed its layout from re-engined to mid-engined, but the engine itself remained the same: a naturally aspirated 6.2-liter 16-valve V8 LT2 with a maximum output of 502 hp and 637 Nm. The octave Corvette's chassis can handle much more power, and the Z06 version has finally made its debut. This suffix was first used for the second generation Corvette in 1963 and meant a package for a road car designed for racing. The new Corvette Z06 has been completely redesigned, with the IMSA championship track Corvette C8.R adapted to the road car.

First, the Corvette Z06 received from its racing cousin a new 5.5-liter short-stroke, high-revving LT6 V8 with a so-called flat crankshaft, four overhead camshafts (32 valves) and a dry sump lubrication system. Aluminum monoblock but with cast iron liners, forged aluminum pistons, forged titanium connecting rods. Bore 104.25 mm, stroke 80 mm, limiting speed 8600 rpm. Direct injection at a pressure of 350 bar. The compression ratio is 12.5. Maximum power – 679 hp at 8400 rpm, maximum torque – 623 Nm at 6300 Nm. Notice how much space there is around the exhaust manifolds: a future even more powerful version of the ZR1 will have turbochargers here.

The gearbox is the same as the base Corvette Stingray, which is an 8-speed Tremec DCT (dual-clutch) automatic transmission, but with a shorter final drive (5.56) all power is sent to the rear wheels via an electronically controlled limited slip differential. Dynamic features have not yet been announced.
