With the release of the new Mercedes-Benz E-Class this spring, the German automotive manufacturer is taking the opportunity to debut their new all-aluminium four-cylinder diesel unit within the new E220 d.
Building on 80 years of diesel knowhow, the new engine is more efficient, powerful, lighter and more compact, delivering around 13% lower fuel consumption and CO2 emissions along with a further increase in output. It has been designed to meet future global emissions standards, with plans to manufacture several output variants in order to reduce fleet consumption. This new family of engines will be applied across the entire range of Mercedes-Benz cars and vans.
This is the first all-aluminium construction of a four-cylinder diesel engine. As well as being significantly lighter and more compact, there is a lower noise level and better comfort vibration, with all components that are relevant to emissions reduction being installed directly on the engine. Because of insulation measures and improved catalyst coatings, there will be no need for engine temperature management during cold starts. Additionally, reducing the emissions results in fuel savings, especially on short journeys.
Mercedes vision of sustainable mobility attaches key importance towards optimising modern diesel engines alongside hybrid and all-electric vehicles. Particularly in Europe, where the popular diesel engine can make important contributions towards reducing fleet consumption. All signs point towards them being on the right track. In the two decades since 1995, the average consumption of the passenger car fleet has fallen by almost half and Mercedes-Benz already have 68 models that emit less than 120g/km with 108 models labelled A or A+ for efficiency.
Prof. Dr. Thomas Weber, Head of Mercedes-Benz Cars Development said:
“In our opinion, the diesel engine is indispensable in trucks and cars if we want to further reduce the CO2 emissions from traffic.”

Good article. Any news on the 3ltr engines. I have heard there are going back to a straight six.
Hi Andy, as far as as im aware yep 3.0-litre is straight-six, 2 litre is 4 cylinder and 1.5 litre 3 cylinder. Its a modular build, with each cylinder = 500cc.
