New world's best Cd for a current production car: 0.24, Mercedes 2009 E-Class coupe

And they did it in a pretty conventional-looking car:

On top of that, the engines (available in Europe, at least) are 17% more efficient than the previous model.

From the official press release:

...The most aerodynamic variant of these coupés achieves a new world best in terms of drag coefficient: with a Cd-figure of just 0.24, this model is the world's most aerodynamically efficient series-production car.


The best example is the twin-turbo diesel E 250 CDI BlueEFFICIENCY Coupé, which consumes 5.3 litres of diesel per 100 kilometres (44 mpg US / 53 mpg Imp) and emits 139 grams of CO2 per kilometre, making it one of the most economical vehicles in its class.

This exemplary low fuel consumption rate has been achieved not only been because of the new engines, but also due to a number of practical measures.

These include on-demand activation of the steering and fuel pumps, the use of tyres with low rolling resistance and an alternator control system which takes account of the current driving situation and the vehicle's electrical power requirements, plus the very important contribution made by outstanding aerodynamics.
