The Frankfurt Auto Show is one of the automotive worldâ€s biggest and most exciting events. Every year, manufacturers unveil their hottest new products and concepts in a dozen exhibit halls in eight different buildings. The media preview took place on September 12 and 13, and there was plenty to see.

Citron C-SportLounge Concept

Perhaps the most beautiful concept car at the show was the Citron C-SportLounge, an aerodynamically advanced touring car. Designers generated a drag coefficient of 0.26 in part through a reverse mobile airfoil under the structure at the rear of the vehicle. The cylinder-activated, three-position mechanism increases downforce and enhances vehicle stability at high speeds. It also sharply increases drag when braking to aid in emergency stopping. An exceptionally high-tech interior echoes the futuristic exterior styling nicely.
