Neil - the previous generation smart with the small diesel was sold in Canada for a number of years. The new model the US has now is the same as we get here - gas engine only.

Keith: congrats on the media exposure.

I doubt you'll see any effect with VGs. I've not seen any credible evidence that they make a significant difference on the trailing edge of a bluff bodied vehicle like your smart.

The benefits of a partial boat tail, however, are not theoretical. Properly designed, it will undoubtedly reduce drag & lower highway fuel consumption. As far as aeromods go, the back of the vehicle is definitely where you should focus your attention (both professionally and on your own vehicle!).
