Mercedes-Benz's modern test bench building.

Before the new V6 and V8 engines were allowed onto the roads, they had already absolved a series of torturous trials, for example on the engine test benches of the test facility in Untertürkheim. 24 of the very latest engine test benches are installed on each floor of this imposing three-storey building. These 72 test benches are in operation by day and night, otherwise it is impossible to complete the enormous test programme to which Mercedes-Benz engineers subject all engines.

A wide range of road and load situations can be simulated on the test benches, reflecting every conceivable operating profile such as hot and cold starts, stop-and-go and long-distance driving under very varied conditions. All in all, the new V8 engines from Mercedes-Benz and their ancillary units were required to absolve 52,000 test hours, of which 27,000 were endurance runs.

In parallel with this, extensive practical trials were started in all the climatic zones of the world – in the winter cold of the Arctic and the merciless heat of Death Valley (USA), in desert sands and the thin air of Alpine regions or in tropical jungles.

The programme also included fast laps on e.g. the high-speed racetracks in Nardo (Italy) and Papenburg, as well as stop-and-go driving in busy inner-city areas. All in all, the different test vehicles with the new V8 engine covered almost seven million kilometres under very varied conditions. Similar figures apply to the V6 engine.
