A cruise control system that can "see ahead" is about to go live. Predictive Power Control, now available in the new Mercedes-Benz Actros, reduces fuel consumption by an additional three percent. Because the system is familiar with the topography of the road ahead, it is able to respond in a way that will deliver the most fuel-efficient performance. This new driver assistance system really comes into its own when negotiating up- or downhill gradients. As the first GPS-based cruise control system, Predictive Powertrain Control not only intervenes to control speed and braking, but can now also regulate the transmission.
