Not every 2-stroke is evil, and with some developments such as direct injection they can still be more efficient and less pollutant than a comparable 4-stroke, and remain lighter and more compact.

The hub motor may be the answer. It frees up a LOT of space. But there are no hub motors (at least in the DIY market) large enough.

EnerTrac makes one for a motorcycle with a continuous rating of 10kW/30kW peak, but unfortunately it is meant for a motorcycle so it is spoked with a motorcycle rim.
It could possible be retrofitted for automotive use, but that's beyond my capabilities.

Unless someone knows of a readily available hub motor, that idea is moot.

With 40kw/120kw there might be enought power to a compact car, (even a Prius
). There are better ones, such as those from Protean Electric (70kw each if I remember correctly), but then it's big money. Anyway, you would need a controller for the hub-motors...
