State-of-the-art six-cylinder in-line engines of the latest engine generation operate at the rear. With their displacements of 7.7 and 10.7 litres, respectively, they are compact yet powerful at the same time. Their outputs range from 260 kW (354 hp) to 335 kW (456 hp), depending on the model.

With the OM 470 engine, the first change of the soot particle filter in touring coaches is due only after 360,000 kilometres, followed by change intervals of 240,000 kilometres each. In the OM 936 engine, the oil has to be changed every 90,000 kilometres for inter-city and touring coach operations, and in the OM 470 engine every 120,000 kilometres.

The Tourismo OM 470 powered by the 265 kW engine is equipped with the Mercedes-Benz six-speed manual transmission, manufactured in-house. However, many coach operators prefer the fully-automated eight-speed Mercedes-Benz GO 250-8 PowerShift transmission with steering column lever control.

This transmission, specially developed for buses and coaches, impresses with its perfect gear ratio adjustment and equally smooth and fast gearshifts. It relieves both driver and drivetrain together with its clutch. In practice, high elasticity and powerful pulling away at low engine rev speeds are particularly important, as they offer the driver optimum power transmission from the engines.

And the business also benefits: from low energy consumption, high reliability and long maintenance intervals. These features make the Tourismo a highly economical vehicle that pays for itself quickly.

Economic efficiency for our customers was the guiding principle during the development of the Tourismo. The broad range of equipment enables a more targeted selection according to the requirements and thus offers the best prerequisites for a cost-effective use.

Based on the proven drive concept of the six-cylinder in-line engine, the OM 936 with its 7.7 litres of displacement serves as the entry-level engine. Furthermore, the OM 470 with 10.7 litre displacement is also used. In the spotlight: the engines with 290 and 315 kW (428 hp).

The centrepiece of the drivetrain range is the OM 470 six-cylinder in-line engine with a displacement of 10.7 litres and four output levels between 265 kW (360 hp) and 335 kW (456 hp). It combines high-level driving dynamics with low energy consumption. Thanks to SCR technology, this engine with BlueTEC 6 diesel technology operates in an environmentally friendly and economical manner. The OM 470 powered by the 265 kW engine is equipped as standard with the Mercedes-Benz six-speed manual transmission, manufactured in-house. The comfortable, smoothly shifting, automated eight-speed Mercedes-Benz GO 250-8 PowerShift transmission is available as an option.
