The future might be in a diesel-electric hybrid ... diesel motor turns at a fixed rpm to recharge the batteries ... the potential for 100 mpg is NOT outside the realm of possibility.

There is a reason why every locomotive has that combo. Then again, the locomotives NEED the weight of the batteries.
Daimler-Benz originally planned to use a diesel-electric hybrid in the Mercedes R series cars. Considering all their experience in building diesel-electric hybrid u-boat power plants during WW2, that would have been a great combination.
