Specifications
The OM648 Mercedes-Benz 3.2L diesel engine is designed to deliver a strong combination of performance, efficiency, and long-term durability. Its inline-6 configuration provides smooth and balanced operation, while the 24-valve DOHC cylinder head helps optimize airflow and combustion. The OM648 engine features a robust cast-iron block, aluminum cylinder head, chain-driven camshafts, and Bosch common-rail direct fuel injection operating at high pressure. The variable-geometry turbocharger (VGT/VNT), combined with an intercooler, provides responsive acceleration and strong torque across a broad engine-speed range. With its combination of six-cylinder refinement, substantial torque, advanced diesel technology, and proven Mercedes-Benz engineering, the OM648 remains a popular engine for replacement, restoration, and performance-oriented applications.
Engine Variants

The OM648.960 is a powerful 3.2-litre diesel engine used in the Mercedes-Benz W220 S320 CDI from 2002 to 2005. It produces 204 PS and 500 Nm of torque, giving the luxury S-Class strong acceleration and smooth highway performance. This version was designed to provide a good balance of power, comfort, and efficiency.
OM648.961 β 204 PS (E-Class)
The OM648.961 is another 3.2-litre version of the OM648 engine, mainly used in the Mercedes-Benz W211 E320 CDI from 2002 to 2006. It delivers 204 PS and 500 Nm of torque, making it capable of providing strong performance while maintaining the smooth driving experience expected from an E-Class diesel.
OM648.961 β 177 PS (E-Class De-tuned Version)
This version of the OM648.961 was a de-tuned variant, meaning it was designed to produce less power than the standard 204 PS version. Used in the W211 E280 CDI, it produces 177 PS and 425 Nm of torque. The lower output was aimed at providing a smoother and more controlled driving experience while retaining the benefits of the 3.2-litre diesel engine.
