The Mercedes-built 3.0-liter CRD produces 218 hp (160 kw) of power at 3,800 rpm and 510 Nm of torque at 2,000 rpm—33% more power and 28% more torque than its 2.8-liter predecessor previously offered in Europe. Built in Berlin, Germany, the new V-6 CRD engine is entering series production.

Mercedes made enhancements to the engine design ranging from the mechanical system and airflow dynamics to the electronic engine management and emissions control.

The common rail direct-injection system has been refined, achieving greater progress in fuel consumption, exhaust emissions and combustion noise. Newly developed piezo injectors operate more rapidly than the previous solenoid injectors, ensuring a precisely metered fuel supply to the cylinders.
