What Car?, the UK’s biggest car buyer’s guide, has named Mercedes-Benz the winner of its 2010 prize for best safety innovation for the ATTENTION ASSIST feature, which is designed to combat overtiredness in drivers – one of the most frequent causes of accidents. The Mercedes-Benz S-Class also took home the Car of the Year Award for best buy in the luxury segment for the fourth time in succession.

Other active safety features on the E-Class include Adaptive Highbeam Assist, Lane Keeping Assist, Blind Spot Assist, Speed Limit Assist, the PRE-SAFE® Brake which initiates partial or emergency braking automatically if there is an acute risk of a head-to-tail collision, and DISTRONIC PLUS proximity control.
