Its carbon fiber and aluminum shell is home to a mid mounted turbocharged gasoline engine and an electric drive system that delivers 357 horsepower and an all electric range of up to 22 miles at a maximum speed of 75 mph. Complementing this engineless mode of travel are a number of noise attenuation measures aimed at keeping wind noise and road noise levels to a minimum. The result is an eerily quiet cabin that provides disruption free listening through the standard harman kardon sound system. Of course, hammering the throttle brings to life the turbocharged 3 cylinder engine and its uncharacteristic baritone bark. And while a 0 60 time of 3.8 seconds is all well and good, the i8 s unrelenting power delivery is what truly separates it from conventional sports cars.
