8. Chevrolet Volt 1.4L (1398 cc)
The Chevrolet Volt uses a unique extended-range electric power-train that has a gasoline engine that acts as a generator for the car’s electric motors. That engine is a 1.4-liter (1,398cc) displacement engine which makes 85 hp. That little engine aids the electric motor and battery to get a 94 MPGe rating by the EPA. At $39,145, the Chevrolet Volt isn’t the cheapest car on the list, but it certainly is the most high-tech, and thanks to that Voltec, extended range electric powertrain, the Volt can go around 800 miles on a single tank and charge.
