How to collect and use wasted potential energy. A few ideas I had rolling around my head was a front wheel drive engine / rear wheel powered compressed air drive. Engine cut off and free wheel front drive unit at take off where most fuel is burned. Using rear compressed air to accelerate the vehicle to even a modest speed of say 30-40 mph would save a considerable amount of fuel. Front engine would turn on and continue to propel as normal. Perhaps use a turbo to provide the compression when decellerating (EOC?) as the turbo would continue to spool. Not sure if the additional weight added would provide a benefit. Engine would be a small turbo diesel.
Modify the transmission design to compress fluid and drive only the tranny at initial take off. Car would use the compression drive to fill only when braking, to provide additional stopping assistance and allow the engine to freewheel.
Best solution would be to design a better propulsioning system / engine. The piston design is archaic. The piston design can only provide power through 45 degrees of it's 360 degree rotation. Diesel engineers now pulse the injector several times during the power stroke to maximize this short range of potential.
