In fact on their production cars they didn't improved aero significantly during last 15 years my 1997 sedan is 0.31 and my 2001 MPV is 0.33.

Last time I heard about the insight II and prius III on TV, the journalists said they were always not looking like cars... This is because these people can't understand the aero gains that Renault will continue to have "cubes". Happily these cubes can be rather "small" and "light".

I hope that the help promised by government because of last crises will push them to apply their aero knowledge. The help is conditioned by keeping employment and a real improvement of fuel consumption (the FE improvement during last 2 years was only because people were buying smaller cars).
