Thinking out loud here, one less wheel bearing, and one less rotating mass, a little less overall weight <maybe>, perhaps less friction between the road and rubber contact patches <although, psi on the now single rear tire goes x2, so friction goes up by some amount, maybe 1.5?>. Is the sum of all that enough to where you'd expect an improvement of 20%-25% over an OEM Metro?
BTW, I love your electric single rear wheel idea, you'd just need to make the motor passive when engaging the ICE. Although still alot of work, the body mods you are talking about get easier if you aren't going to enter it into a car show... IMO crude is good enough to prove the concept, the 2nd gen can be 'purdy'  |
The tapering I suggested (in all dimensions) starting at the rear edge of the B pillar would decrease the Cd, as well as some other body mods --like we talk about on every other thread-- belly pan, grille block, etc.
