Whereas the BMW i3 represents a nice green initiative by BMW, the i8 symbolizes the sport potential of this technology. By pairing a small 1.5-litre turbocharged 3-cylinder with the electric power, the BMW i8 manages to develop 357 horsepower and 420 pounds of torque while consuming about the same amount of gas as a Toyota Prius. Meanwhile, its modern look makes the BMW i8 a real head-turner.
