As a kid I read about the fairly simple hydraulic power storage retrofit car by Popular Mechanics 30 years ago, which demonstrated how efficient a car could be just from power curve and regen braking. It had the production olds 455 engine, tuned to the max efficiency part of the power curve, driving a hydraulic system with what's called an accumulator. This stores hydraulic pressure like a water pressure tank. The engine only kicks on when the accumulator is empty. The brakes cause regenerative braking by reversing the hydraulic drive pump/motor. Mileage was 45 mpg around town for a 3900lb car, with 300hp engine which was silent at stoplights, and could smoke the tires off the line. I don't remember the freeway mileage, but that was great too. Don't expect to see that from the auto manufacturers, tho'. Too simple. Their approach has to be to screw up anything with fuel efficiency, and do things like Ford's stupid HLA concept: popularmechanics.mondosearch.com
