If they want a serial hybrid why not use a high effencency Stiring type engine to run generators to re-charge the batteries?

They could computer control 2-3 banks of them to kick on as the battery gets lower and based off car speed, etc...

Oh well.

Just speculating but with the more powerful engine they could be doing away with the electric drive when the battery is depleted or give the driver the choice of electric drive or the more zippy gas powered drive.

Good point. Also a turbine should work just fine, as the electric drive would solve the problems with lag and torque. And a diesel would be an improvement for fuel economy.

Or even a diesel, specifically tuned to one RPM range could get excellent efficiency. Maybe they are thinking of turning this thing into a "regular" hybrid?
