With the 2015 Mercedes-Benz C-Class, Gorden Wagener faced a challenge most car designers would love to have: make a best-selling car sell even better. The 2015 model is longer and wider, but weighs 200 pounds less due to a partly aluminum body, which also offered more freedom when it came to curves and detailing. To give the C-Class a self-assured look, Wagener patterned the headlights after a human eye, with the circular torch as the eyeball and a row of LEDs above as an eyebrow (and turn signal). Wagener pushed the cabin back, lengthening the hood and shifting the focus of the car to the rear. He also tapered the cabin and raised the back for a classic "dropping line" stance. As a result, the C-Class is unusually aerodynamic.
