Audi Q7 driver assistance systems - Predictive efficiency assistant with ACC

The predictive efficiency assistant is a groundbreaking innovation from Audi. It uses the route data from the navigation system to alert the driver of situations in which it would make sense to reduce speed, such as before curves, towns or speed limit signs that are not yet visible. In collaboration with adaptive cruise control (ACC) and traffic sign recognition, the system adapts the preselected speed to the route and the speed limits. The predictive efficiency assistant, which can also take over predictive control of the free-wheeling function of the eight-speed tiptronic, has the potential to reduce fuel consumption on interurban roads by as much as ten percent.
