The ideal setup in most hybrids so far has been a naturally aspirated Atkinson cycle. Simpler, lighter and about as efficient as the diesel cycle just down on power. Electric boost takes care of that problem and at cruising speed we don't need much power. Toyota and Ford have both gone this route. Some wonder if GM will do the same in Volt 2.0. VW tho has gone whole hog with a new gas engine with all the goodies. Beats the TDI in combined mileage by 25% without loss of performance.
A diesel in the volt would have little benefit. Since it rarely drives the wheels, the torque benefit is lost. More weight for what?
