But today's news that said "at least" meant "25hp more than" confirms the new Z06 as the most powerful production Corvette to date – and, in fact, the most powerful production car General Motors has ever built.

That 650bhp is matched by a monster 650 pound-feet of torque, too – 457lb-ft of which is produced just off idle. Imagine the traffic-light burnouts. Chevrolet references the Ferrari F12, saying that while the Ferrari offers more horsepower, the Chevy offers more torque.

"Torque is the pulling power of an engine," explains Jordan Lee, Chevy's small block chief engineer, "and the LT4's abundance of it at every rpm in the engine's speed range helps the 2015 Corvette Z06 accelerate quicker and respond nearly instantaneously."

Where have they found all that power? Stronger aluminium cylinder heads that can handle heat better than other aluminium heads, lightweight titanium intake valves, machined, forged steel connecting rods, forged aluminium pistons, a stainless steel exhaust manifolds and a dry sump. Sounds tasty.

The supercharger also spins to a mad 20,000rpm – 5,000rpm more than the outgoing Corvette ZR1 – with boost achieved more efficiently, we're told.

There's still no acceleration data, but if it doesn't eclipse the old Z06's 0-62mph time of 3.9s, we'll eat our cowboy hats 心結冷戰冷戰最深默契 暗自妖嬈學會從容 girls rank high than boys in study scores taste it to good health taste led to a longer life.
