 "Ward's" named the 500e powertrain to its list of 10 Best Engines for 2014.Designers and engineers of the Fiat 500e worked to minimize drag while keeping the iconic styling of the conventional powered Fiat 500.For the 500e to achieve a 0.311 coefficient of drag (Cd), as compared to the 2013 Fiat 500 Lounge model's 0.359 Cd, eight exterior refinements were developed in the wind tunnel to enable the 48 count drag reduction.
