Mercedes-Benz wins Safety and Technology award for DiesOtto

At their annual award ceremony, British magazine AutoCar singled out the Mercedes-Benz DiesOtto engine concept for recognition. The DiesOtto is a turbocharged homogeneous charge compression ignition (HCCI) engine. It first appeared in the F700 concept at the Frankfurt Motor Show in September. HCCI runs essentially as a diesel engine under certain operating conditions but runs on gasoline and produces far fewer emissions than a diesel without expensive after-treatment systems. The 1.8L engine produces the power of a 3.5L V-6 while achieving 44.3mpg.
