In spite of the fuss about electrical drivelines is Mercedes-Benz investing heavily in new combustion engine technology:
With its completely newly developed family of diesel engines, Mercedes-Benz is the first manufacturer to put diesel vehicles on the market that already fulfill the stricter emission limits planned for the EU as of September 2017. This has been achieved through an integrated technology approach, which includes new stepped combustion chambers and further developed exhaust-gas recirculation. The new engine design also allows all components for exhaust-gas recirculation to be positioned directly on the engine, instead of under the car floor as hitherto. This significantly enhances the system’s overall effectiveness – largely independently of ambient temperatures and driving style.
The market launch of the completely newly developed four-cylinder diesel engine OM 654 is in the new E-Class. The E 220 d now consumes as little as 3.9 liters of fuel per 100 kilometers (combined according to the NEDC currently prescribed for all manufacturers), although the engine is more powerful than its predecessor (143 kW/195 hp compared with 125 kW/170 hp). This corresponds with CO2 emissions of 102 grams per kilometer.
The new four-cylinder engine is the first member of a modular engine family that will be applied throughout the entire portfolios of Mercedes-Benz Cars and also at Mercedes-Benz Vans. Several levels of power output are planned, as well as longitudinal and transverse installation in vehicles with front-, rear- and all-wheel drive. In this way, Mercedes-Benz will equip its entire range of diesel cars in Europe with this latest engine generation including SCR technology (selective catalytic reduction) by 2019 at the latest.
