Well, there are several proven techniques that are not used because of one reason or another.

Alcohol/water injection, for one. Manufacturers don't use this because if you program your engine to run well with alcohol injection (making more power and using less gas in the proess), you run the chance of engine damage if the owner forgets to refill the water tank.

Then there's ultra-lean burn. Which they can't use anymore because of strict emissions testing.

And of course, aerodynamics and ultra-light weight. Which they can't do because well-off buyers are picky. Just look at the Mirage... ultra-low drag coefficient, super low weight (for a five star car!) and most Western journalists slag it for being too tinny and cheap. Well... duh... it's built to be light and cheap!
