The Insight is a nice example of function over form when it comes to aerodynamics in production cars. But can it be improved further? Autospeed gave it a shot,
and it didn't work.
What went wrong? Well, I think it's simply that a new undertray did not have the potential to make a huge difference on this car in the first place.
Darin, with his Metro's "aero dirty" underside, when compared to an Insight, only saw a
2.2% increase from a full belly pan.
The way they monitor fuel economy on the Insight, in L/100km with one decimal, is quite imprecise. That is especially true when you get in the sub 3 L/100km, where each tenth change is at least a 3% change in fuel economy.
The wheel fairings were a nice touch, although they could have been better designed.
But anyway, thanks to autospeed for their newest aero article, it's always nice to read peoples' hands on experimentation.
