Mercedes-Benz Tourismo RHD M2 – 16/2

New top-of-the-range engine offers outstanding performance

With the change of model, Mercedes-Benz is now adding a new top-of-the-range engine to expand the output spectrum for the Tourismo RHD. The three familiar output categories of the in-line six-cylinder unit, with 265 kW (360 hp), 290 kW (394 hp) and 315 kW (428 hp), have now been topped by a variant with an output of 335 kW (456 hp) and a particularly powerful peak torque of 2200 Nm.

The bare facts of output and torque of this new variant already give an indication of its outstanding performance. With a specific output of 31.4 kW per litre of displacement (42.7 hp/l) and a specific torque of 206 Nm/l, the OM 470 is one of the most powerful engines in its size category, making it the obvious choice for customers seeking that combination of exceptional performance and outstanding economic efficiency.

New entry-level engine with impressive fuel efficiency

Mercedes-Benz is also extending its engine portfolio for the Tourismo RHD at the other end of the scale. The key word in this case is downsizing: the new addition to the high-decker's engine range is the super-compact in-line six-cylinder Mercedes-Benz OM 936, with a displacement of 7.7 l, which can be fitted as an option. Courtesy of two-stage turbocharging, the engine achieves an output of 260 kW (354 hp) and a peak torque of 1400 Nm, thus proving itself remarkably powerful. The engine with this power level has already proved its capability in the compact Tourismo K, the inter-city bus Mercedes-Benz Intouro and even in the mighty Citaro G articulated bus, so now it's the turn of the high-deck touring coach.

The new compact engine is available for both two-axle variants of the Tourismo RHD. It is the ideal solution for situations where exceptional economy in terms of fuel consumption is sought in conjunction with maximum payload for a full complement of seats in topographically less challenging environments. Examples for this might include shuttle vehicles, buses for combined excursion and regular-service use, or countries and regions with traditionally lower performance requirements.

Two engines with a total of five output ratings

The exceptionally broad engine portfolio for the new Tourismo RHD therefore comprises two in-line six-cylinder engines with altogether five output ratings:

- OM 936, displacement 7.7 l, output 260 kW (354 hp), torque 1400 Nm
- OM 470, displacement 10.7 l, output 265 kW (360 hp), torque 1700 Nm
- OM 470, displacement 10.7 l, output 290 kW (394 hp), torque 1900 Nm
- OM 470, displacement 10.7 l, output 315 kW (428 hp), torque 2100 Nm
- OM 470, displacement 10.7 l, output 335 kW (456 hp), torque 2200 Nm

All engines meet the Euro VI emission standard. The basis for the emission control system is provided by SCR technology with AdBlue injection. The tank system for diesel fuel is positioned behind the front axle and is the same on all models. The double tank has a capacity of 480 l, can be filled from either side and, in conjunction with the low fuel consumption of the new Tourismo RHD gives the coach an excellent range. The tank for AdBlue is located on the right-hand side behind the front axle and has a capacity of 40 l.
