Photos and Videos: Mercedes-Benz PRE-SAFE Brake System Video

Summary: Mercedes-Benz has developed a new, ground-breaking safety system called PRE-SAFE Brake that is featured on the 2010 E-Class. PRE-SAFE uses radar to gauge how close you are to traffic ahead, and if you are going too fast to safely avoid a collision, it engages the brakes up to 40-percent and primes the brakes to deliver full power when you slam on the pedal. If you don't engage the brake pedal by a half second before impact, the car will engage the brakes 100-percent, reducing the car's speed.
