Threshold Strategy - Halving the Drag Coefficient Seems Possible
Threshold Strategy - Halving the Drag Coefficient Seems Possible - ATZ online

Quote:
The drag coefficient of cars is gradually falling to the level of cd = 0.25, but its progress is so hesitant that you could be forgiven for thinking that this figure represented a limit set by the laws of physics. It will be demonstrated how the apparent obstacle can be overcome. A further cut in fuel consumption can be achieved if the reduction in drag is accompanied by the corresponding use of lightweight structures and a specially designed powertrain.
Close, but not exactly.
