So the Prius went all out and the M3 just followed it around? Or was there a set speed?

-yep the prius kicked it and the m3 just kept pace. Of course, if the prius drove slower, it would be a different story, but that wasn't the point of the experament

That's why we have real engineers build cars not john Q... whoever.

Economy is all about efficiency....

And I bet the M3 produced way less emissions as well.
