Electric Vehicle Aerodynamics – EV Drag Coefficient List

Aerodynamics are key to electric vehicle (EV) efficiency and driving range. The basic principle is simple; the lower the coefficient of drag (cD), the further you can travel per charge. The slickest cars follow nature. A bird that’s shaped like a brick cannot fly. Unfortunately, electric vehicle aerodynamics have taken a back seat to the whims of the market. In the quarter century since the introduction of the General Motors EV1, it’s 0.19 cD remains unrivaled.

The 1996 GM EV1 is the most aerodynamic electric vehicle sold in America.

While sedans and coupes are inherently more aerodynamic than sport utility vehicles (SUVs) and crossovers, they have fallen out of favor with a significant number of consumers. This is unfortunate for a number of reasons, but modern families need alternatives. SUVs are spacious, but a box with rounded corners struggles to cut through the wind.

Smaller cars face challenges, as well. The Chevrolet Bolt EV’s .0308 cD is a prime example. How far could a vehicle based on the Bolt platform travel if it had a body as slick as the GM EV1?
