EfficiencyAt Audi, doing less is something we’re tryingto do more of. We’re working to use less fuel,release less CO2 and waste less energy. It’swhy we’ve incorporated a number of moreefficient technologies into the Audi Q7.RecuperationWhen a vehicle brakes, the discs convertthe kinetic energy into thermal energy, whichis wasted as it cannot be used. With arecuperation system like the one in the AudiQ7, the kinetic energy is converted into usefulelectrical energy. The way it works is simple.While the car is coasting or braking, thealternator voltage is raised above the level ofthe basic electrical system, which enables thealternator to generate electrical energy andstore it temporarily in the battery. When thevehicle accelerates, this energy is used torelieve the load on the alternator, resultingin a fuel saving of up to 3%.14Images for illustrative purposes only.
