Slippery Slope: Production Cars Making Jaw-Dropping Aerodynamic Gains
A new trend sweeping the industry is aerodynamic vehicles that look fashionable, rather than like science projects.

While not quite as slippery as the XL1, the CLA is part of a new trend sweeping the industry: Aerodynamic vehicles that look fashionable, rather than like science projects. In addition to the Mercedes, mainstream models including the Chevrolet Malibu and Toyota Avalon are sporting shockingly low Cds without looking like Sci-Fi props.

Teardrop-shaped bodies, fender skirts and other typical aero gimmicks may work miracles in the wind tunnel, but when they hit the street, consumers reject them. GM’s EV1 and first-generation Honda Insight HEV were the most aerodynamic vehicles of their day, sporting Cds of 0.19 and 0.25, respectively, more than 10 years ago. Despite innovative design and breathtaking efficiency, both flopped.

There are many reasons why the cars failed, but nerdy fender skirts and pinched hindquarters did not help.
