Audi to mimic Efficient Dynamics to reduce fuel consumption and emissions

Following on the heels of BMW and their Efficient Dynamics initiative, Audi seems ready to mimic their Bavarian rival. With some sort of mandatory European CO ₂ limits almost certain to be passed, almost all manufacturers who do business on the continent will have to do something. Audi has already shown their hybrid system on the A4 drivetrain at the Detroit Auto Show, in addition to the Q7 hybrid that is coming. On top of that, they are developing simpler automatic start-stop systems and working on weight reduction. They are also working on a system of thermostatically-controlled flaps behind the grille that would cut air-flow through the engine compartment when cooling isn't needed. This is a similar system to what Cadillac showed on their Provoq concept to reduce drag under light load conditions.
