The i8’s plug-in hybrid drivetrain uses a combination of electric motors, lithium-ion batteries and a turbocharged 1.5-litre petrol engine, to provide supercar performance along with city car running costs. Switch to the sportiest mode, and you get the full force of all the various motors, amounting to a total of 357bhp. Granted, it doesn’t have the same kind of organ-bashing acceleration you get in more conventionally powered supercars, but with a 0-62mph time of just 4.4 seconds, it’s still easily fast enough to put a big, stupid smile on your face. And, with so many power sources contributing to the action, at least one of them always has something left to give in any situation. The pace is accompanied by a noise that’s worthy of a supercar: the petrol engine may only have three cylinders, but listening to it, you’d swear it had at least six. Switch to one of the more eco-focused modes, and you can trundle along in near-silence with the electric motor doing most, if not all, of the work. A full charge of the battery (which takes about three hours from a domestic three-pin socket) will let you drive for up to 22 miles on electric power alone, up to a speed of 75mph.
