The Mercedes-Benz C-Class

Developed in less than four years and at less than $600 million, the all-new C-Class incorporates $1800 worth of improvements as standard.

One of the Mercedes-Benz C-Class's more impressive attributes - and they are numerous - is one that can be heard and felt, but not seen: drag.

Aerodynamics engineers at Mercedes reduced it by 13% over the previous-generation C-Class, to 0.26 Cd for the C180 model. The company notes that drag can account for more than half the fuel consumption of a passenger car.
