Chevrolet has confirmed that its upcoming Corvette C7 Z06 will feature a supercharged V8 producing 650bhp and 650lb ft.
The Corvette Z06, which made its debut at the Detroit motor show earlier this year, is powered by a 6.2-litre 'LT4' V8 engine.
The Z06 is consequently the most powerful production car ever made by General Motors. Previously, it was thought the Z06 would produce in the region of 625bhp.
An upgraded version of the standard C7 Corvette, the Z06 moniker first appeared on the C2 generation of the car in 1963. It was followed, decades later, by the C5 Z06 and C6 Z06.
This generation of Z06, however, is the first with a removable roof, optional eight-speed automatic transmission and - more notably - a supercharged V8 engine. Chevrolet says the massive torque coming from the engine is 28 per cent more than that offered by the V12-powered Ferrari F12 Berlinetta.
The company says that, at idle, the engine is still producing 625lb ft of torque, and is able to maintain up to 90 per cent of available torque between 2500-5400rpm. The engine utilises direct injection and variable valve timing.
In line with its high-performance nature, the LT4 in the Z06 benefits from a dry sump oiling system, ensuring the correct oil pressure is maintained in strenuous conditions.
Other notable design features of the engine include a 10:1 compression ratio, titanium intake valves, forged aluminium pistons and machined connecting rods.
Thanks to the use of a compact 1.7-litre Eaton supercharger, which spins at up to 20,000rpm, the LT4 is only 25mm taller than the standard LT1 engine. This helps keep the Corvette's centre of gravity low, improving its handling characteristics.
