The huge fuel economy improvements automakers are being forced to make by 2016 may not seem like an achievable goal.

But the strategy they'll use to increase fuel economy for cars by an average of 42% and for SUVs by 30% involves creating a wide spectrum of new technology. This technology will improve fuel economy on all vehicles and produce some with "blow-the-doors-off" mileage, way above the requirements.

Since higher fuel economy requirements have been in the cards for a while, many of these of these technologies are already on the way. Broader applications are coming, with many of these features appearing on cars that probably wouldn't have gotten them before.
