drag coefficient

It may not look it, but the 2014 Mercedes-Benz CLA-Class is aerodynamic as all get out. How slippery is it? Well, the compact sedan has a drag coefficient of 0.23, which will make it the world's most aerodynamic series production car when it goes on sale in the US this September. By comparison, ...

Aerodynamic performance is getting increasingly important for every new vehicle as automakers strive to improve fuel efficiency and reduce noise. That's especially true for hybrid vehicles as manufacturers aim for MPG ...

The Aerocivic apparently has a distant relative from Canada. Darin Cosgrove, founder of Ecomodder.com, has added a boat tail to the back of his 1998 Pontiac Firefly (which is what the Geo Metro was called up north). According to Wired, the modified bodywork was constructed from cardboard, ...

Back in the spring of 2008 when General Motors took us on a tour of its wind tunnel facility, chief engineer Frank Weber emphasized the importance of aerodynamics in maximizing the electric driving range of the Volt. At that time, all we got see was a one-third scale model covered in various ...

You can have all the most efficient engines in the world, but if you're trying to drive a barn through a hurricane they are not going to help one bit. Mercedes knows that, which is why, in addition to highly fuel-efficient ...

Did you know that geese flying in formation inspired the 1934 Chrysler Airflow, perhaps the first streamlined car ever built? Aerodynamics didn't start playing a major role in automotive design until the '70s and the first gas crisis. The measuring stick for automotive aerodynamic is the ...
