I have no idea what an astra is. Anyways, why would you want to "accelerate" with a 1.4 or 1.6? That isn't even an engine. My lawnmower has a bigger engine.
With the Corvette it was different.
You floor it, and it immediately flipped two gears down, revs at 6,000, going from 120 km/h to 190 km/h in a blink of an eye.
Maybe BMW should learn from the Americans.
