IIRC, diferentials are something like 5% of the drive line losses. I think it's also the largest contributor (or top 3).

But that said, I agree with you. The ability for a car to track significantly increases from 1-2 as you're now tracking in 2 dimensions rather than 1....

Now, if the vehicles were small and light..... Then I'd have no problems with 1wd

Spinning he correct tire is more effective than spinning more tires.... For use on roads....
