They were at 78% wheel to wheel a decade ago. Under the same test parameter a gas electric hybrid was at less than 33 %.
Documented, tested, proven.
The weakest link in the system was the use of a bent axes pump, a design going back to WW2. The call was made for a "clean sheet of paper" design for the basic pump-motor capable of much higher efficiencies that the bent axes driving through a standard type differential where pump speeds of 3k rpm were necessary.
Dumping the differential and driving the wheels directly was the solution, with individual drive efficiency approaching 97%.
Accumulators at 99%
This thread will die like many others, overwhelmed by the noise of lack of knowledge.
Test mules were built, 3800 pound 5 passenger vehicles with a 1.9 liter diesel engine producing 80 mpg combined on epa cycles.
Passenger vehicles, not garbage trucks.
