2014 Audi e-tron Spyder
This diesel-electric roadster is an absolutely stunning vehicle that also packs a punch. The vehicle is equipped with a plug in diesel electric power-train that consists of a 69 cell lithium-ion battery pack. The pack weighs 220 pounds and is paired with electric motors to help power the vehicle. The vehicle can hold up to 13.2 gallons of diesel fuel, but still manages to get over 600 miles per tank due to the battery pack.
