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, the most recent body update for the Toyota Prius cut the drag coefficient of that hybrid model to 0.25 from 0.26, while the 2013 Nissan Leaf electric vehicle has a 0.28 drag coefficient, down from 0.29 for the 2012 version. The Tesla Model S? 0.24.

The Mercedes CLA-Class was shown off at Detroit's Westin Book Cadillac Hotel before the start of the Detroit Auto Show, but won't see the light of day on the show floor. Instead, the model is officially being unveiled later this week in at the Mercedes-Benz Fashion Week in Berlin.

The CLA-Class will have a 1.8-liter turbocharged inline four-cylinder that delivers 208 horsepower. The model is expected to be priced at about $30,000. You can read more about it here.
