Similar in size to the Audi R8, the BMW i8 is a 2+2 with a 3-cylinder 1.5 litre engine and generator sitting at the back and driving the rear wheels and an electric motor at the front driving the front wheels, with a petrol tank at the back and the batteries for the electric motor stored in the centre tunnel.
