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.
this is quite important that
The most aerodynamic variant of these coupés
it reminds me of the opel calibra wich had a 0.26 Cd... but only for 8 valve versions with a partly blocked grill and different tires.... the 16calve versuibs differed in some aspects and had a 0.29Cd! something that's not often mentioned.

that doesn't mean this isn't quite an achievement, but i notice the front bumper on the white car and that on the gey car show lower is quite different, especially the shape of the grill and the wheel dams... so one must be a little carefull with reverse engineering
