I know exactly how fast the Porsche Taycan Turbo S is. The read-out on the little motor-sport computer suction-cupped to the inside of the windscreen produced the remarkable number 2.488.

That’s how many seconds it took the newest all-electric car on the market – in its fastest and rather confusingly named Turbo S form – to go from a standstill to 100 km/h. With all-wheel drive and clever electronics, the launch control mode sent it off the line with scarcely a tyre chirp to interrupt the Star Wars-like whoosh.
