Terrain to conquer for next-gen truck
Mercedes assures the future of its unstoppable niche Unimog
players, the Unimog Euro VI engines feature exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) so they can hit the Euro VI targets. Australian heavy vehicle emission standards are now at the Euro V level, with no timeline set for the introduction of the Euro VI standard.
Importantly, the development of the Euro VI Unimogs shows Mercedes is committed to the future of the niche terrainconquering truck that is used for everything from snow ploughing to pulling train wagons.
The new Unimog, with a 24-speed gearbox, has engines from the new Mercedes truck powerplant range which will run from 5.1-litres to 7.7-litres.
The chassis on display was fitted with a four-cylinder OM 934 engine that actually makes more power and torque than a current six-cylinder engine. The new power output stands at 220kW (299hp) with torque hitting the 1200Nm mark.
Six-cylinder engines will also be available in the new Unimog, including a 7.7-litre OM 936, with up to 260kW.
This engine runs a variable camshaft phaser for the exhaust camshaft, which Mercedes says has not been done on any other diesel engine. It says the extra control helps to burn off the material that has been caught in the engine’s particulate filter.
Carrying new technology such as catalysts and AdBlue diesel exhaust treatment fluid on-board means the new generation of Unimogs could have ended up weighing more.
But Mercedes engineers changed sections of the frame to keep the weight in check and introduced aluminium wheels that are significantly lighter than the regular steel rims.
