For almost three decades, the aerodynamic specialists at Mercedes-Benz have been breaking one record after another. The current world record is held by the new CLA-Class, in its BlueEFFICIENCY Edition guise, with a Cd value of 0.22 and a wind resistance area of 0.49 sq. m. The drag coefficient of the new S-Class improves on that of its predecessor by a further two hundredths - with a Cd value of 0.24 it not only sets a new benchmark in its segment, but is the best saloon overall in this respect. The S 300 BlueTEC HYBRID is even more aerodynamic. The diesel hybrid model achieves a Cd value of 0.23 and, not least as a result of this extremely low wind resistance, delivers impressive fuel consumption figures of just 4.4 l/100 km, or 115 g/km CO₂/km.
