I read that, and wasn't impressed either.
Especially on a vehicle with limited power available, a better Cd would have helped to reduce power draw at higher speed.
It's something Hucho has also been pointing out : aerodynamic progress on production cars seems to have stopped at around 0.25 .
Hucho blames the European test cycle which only averages 32 km/h (20mph).
