New Mercedes-Benz Passenger Cars Comply With Euro 6d-TEMP Standard As A Minimum

Significantly reduced NOx emissions is a characteristic feature of vehicles which are certified according to the Euro 6d-TEMP standard. All Mercedes-Benz passenger cars that can be ordered in the new car business now meet this requirement. Furthermore, Mercedes-Benz currently has a whole series of vehicles on the market that already comply with the even stricter Euro 6d standard. This will gradually become mandatory as of 01.01.2020.

The decision made at the start of the decade to develop an entirely new Diesel engine generation is paying dividends. The innovative technologies implemented in the process ensure low NOx emissions. With the changeover to the new engine generation, all new Mercedes-Benz passenger cars available to order now comply with the Euro 6d-TEMP or Euro 6d standards.

The limit values for NOx in emission tests – for Euro 6d these are also at 80 milligrammes per kilometre also during RDE (Real Driving Emissions) tests – are so-called “not to exceed” limit values that must be complied with during each valid RDE test. This means that a vehicle may also not exceed the limit under the worst conceivable combinations of RDE conditions – for example, with a heavy load, in hilly topography, and in unfavourable temperature and traffic conditions. The limit applies not only to new vehicles, but also to vehicles with more than 100,000 kilometres. Results of real-world tests on the road often stay significantly below the limit of 80 milligrammes per kilometre, which is confirmed by independent measurements.

The Euro 6d standard is even more demanding due to its smaller permissible measuring tolerances. It will not become mandatory for new models until 01.01.2020, and one year later for other vehicles. Mercedes-Benz started an engine initiative in 2016, which includes the all-new four-cylinder diesel engines (OM 654 and OM 654q) as well as straight-six diesels (OM 656). On this basis, which is associated with investments of around three billion euros, a whole host of Mercedes-Benz diesel models, from the A-Class to the GLS, already comply with the Euro 6d standard today (the current list plus background information on the emissions standards appears on the following pages).
