Mercedes-Benz E-Class BlueEFFICIENCY: Aerodynamics: Boasting a drag coefficient (cd figure ) of 0.25, the new E-Class is better than other saloons in this market segment. On the road, aerodynamics have a significant effect on fuel consumption: reducing the cd figure by 0.01 alone leads to a fuel saving of up to 0.15 litres per 100 kilometres at 130 km/h.
