New BMW i8

Design The combination of petrol and electric power enables the i8 to deliver gripping torque from the instant the car starts. The 1.5-litre TwinPower Turbo engine creates 231bhp and up to 320Nm, and it partners a 131bhp-equivalent electric motor. Fuel economy reaches as much as 134.5mpg – almost unheard of for a sports car – with CO2 emissions slashed to only 49g/km.
