Daimler has launched the Mercedes-Benz OM 471, under the name "Blue Efficiency Power". The Blue Efficiency Power generation of Mercedes-Benz engines has been specifically developed for use in Europe and is the first of its type to meet, from the outset, the Euro VI emission standard.

The Blue Efficiency Power engines, which share a common basic design, have been under development for five years. Features include the new X-PULSE injection system with pressure booster; an asymmetric exhaust gas turbocharger; emission control with SCR technology, EGR and a particulate filter; and a three-stage exhaust brake. The core design of the engine is based on the new platform used for Daimler's heavy-duty engines built since 2007 in North America and since last year by Fuso in Japan.

The first European member of the new engine generation is the Mercedes-Benz OM 471, with a 12.8-liter displacement. The OM 471 is the first engine in its class to have received type approval and already be available with the coming Euro VI emission standard (which begins taking effect in two years). The OM 471 has a power output range of 310 kW (421 hp) to 375 kW (510 hp) and maximum torque of between 2100 and 2500 N.m.

Among the special features of the Mercedes-Benz OM 471 are its broad range of four power and four torque variants, as well as two different brake power configurations. Typical of the specifically European design of the engine are the variants with enhanced power and torque, which are configured to suit typical usage here as well as to the needs of operators and drivers. The basic line-up of the Mercedes-Benz OM 471 comprises outputs from 421 to 510 HP and a torque from 2100 to 2500 N.m.
