Some are basically a small electric vehicle with a petrol engine that only cuts in occasionally. Some of the fastest super cars in the world now have extremely powerful petrol engines and use electric motors and batteries as well to create incredible bursts of acceleration. Nothing green about that... [quote] If you talk to any 4 wheel driver, the first thing they ask you " you got front and back lockers?" A motor in each wheel would make an awesome 4WD For some things perhaps, but not for extreme off road. There is one big advantage of locking all the differentials, you can feed all of the low range torque into just one wheel if necessary. This is important for rock climbing for example where one wheel might get wedged between two boulders. With four electric motors and no extra super low range gearing, it would not be anywhere nearly as good. It would be much more ideal for a light duty on road 4WD though, many of those around, I drive one myself. Cheers,  Tony.
