Not a lot of room in the M3W for either Tesla or i3 drivetrains. Could be room in the forthcoming alloy chassis though which will be interesting.
There are about 3 different size drivetrains, the ones used on the front are a fair bit smaller than the rear. For the 4 wheelers I would think no issue, for the 3 wheeler I don't know but then maybe look at what some of the Euro companies are doing.
