The Mercedes-Benz Sprinter is to get a new 2.0-litre ‘OM654’ diesel engine to replace its aging 2.1-litre OM651 engine. The new engine is Euro 6D compliant, is around 13% more efficient and is more powerful than its predecessor, producing up to 194PS and 400Nm.
Developed in 2008, the 2.1-litre OM651 is now one of the oldest engines of any panel. Over its 12-year product cycle, it has built up a solid reputation as a durable powerplant with the Mercedes-Benz Sprinter dominating the most reliable van rankings in the last couple of years.

Recent emission standards, like Euro 6, have meant many medium and large vans have downsized but Mercedes-Benz has retained the veteran 2.1 throughout Euro 6 and Euro 6B.
However, Euro 6D has proved to be the final straw. Mercedes-Benz will be replacing it with the OM654 in the Vito and Sprinter vans from late 2020 which, in addition to being more fuel-efficient, powerful and less polluting, also emits less noise and vibrations – creating a more comfortable environment for the driver.
The OM654 is made from aluminium making it 36kg lighter than its predecessor (168kg versus 204kg) and the steel pistons are lined with Nanoslide, an innovative and economical technology designed to reduce the fuel consumption and emissions of internal combustion engines.
Although the power ratings have yet to be announced, we know that the North American 2.0-litre version will be offered in a 163PS/350Nm output although the UK line-up is expected to be more comprehensive mimicking the current 114PS/300Nm, 143PS/330Nm, 163PS/360Nm and 190PS/440Nm, with the larger 3.0-litre V6 OM642 also being dropped.
The engine also currently features in the current E-Class, where it also features a turbocharger and a BorgWarner’s eBooster electrically driven compressor. In the E-Class, it has power ratings of 194PS/400Nm and 245PS/500Nm.
