• Stuttgart, Jul 15, 2010 - The world's safest truck is now even safer: Mercedes-Benz is introducing second-generation Active Brake Assist for the heavy-duty Actros truck. This unique and multi-award-winning safety system now has even greater capability: whereas the first-generation system applied the brakes automatically if it detected a risk of a head-to-tail collision with a slow-moving obstacle in front of the vehicle, Active Brake Assist 2 is also activated if a stationary obstacle is detected.
