Mercedes’ OM diesel engines have seen a long reign in the company’s vehicle lineup, with the OM 651 being the most-produced engine in the brand’s history. Now, however, the OM 651 is being pushed aside in favor of a new OM diesel engine. The OM 654, as it will be called, will be offered in the new Mercedes E-Class as one powertrain option for the upcoming car.

The new OM 654 is said to be significantly lighter than its predecessor, as well as consuming significantly less fuel and releasing fewer emissions. The new diesel engine will debut in the new Mercedes E-Class E 220 d and is expected to provide an NEDC-estimated 60 mpg combined fuel rating, as well as a 25 horsepower boost over the previous engine, which cranked out 170 horsepower in comparison to the new engine’s 195 ponies. Mercedes’ goal in developing the new engine was to meet the standards for the Real Driving Emissions legislature, while providing superior performance and efficiency.
In addition to finding a home among the E Class engine lineup, the new OM 651 is also expected to be put into the A Class, V Class, and S Class models in addition to the Sprinter van. The engine was also designed to be modular and compact so that it can be easily modified to fit the legal restrictions of any of the various countries in which Mercedes vehicles are sold. So you can expect to see this incredible piece of engineering pop up in a number of places soon. Prepare yourself for Mercedes level diesel performance, the kind everyone’s been wanting.
