Power output and transmission of the new powertrain for the Mercedes-Benz Tourismo precisely suit the preferences of British bus operators. It uses the new in-line six-cylinder Mercedes-Benz OM 470 engine with a displacement of 10.7 litres. It is installed vertically in the rear.
The new engine from the BlueEfficiency Power generation is characterised, among other things, by two overhead camshafts, four-valve technology and common-rail injection with the flexible X-PULSE with Pressure Boost injection system. With a DIN weight of just 990 kg and compact dimensions the engine is perfectly suited for weight-sensitive buses and for confined installation spaces.
The new engine is very refined and impresses in all its variants with quick throttle response and agility. It produces a lot of power already at low engine speeds: the engine delivers 95 per cent of peak torque already around a low 800 rpm.
