The Mercedes-Benz OM642DE30LA Diesel Engine 3.0L turbodiesel has been used in Mercedes, Dodge, and Freightliner Sprinter vans since 2007.

The foundation of the Mercedes OM642DE30LA Diesel Engine is a cast aluminum engine block, a feature that is somewhat unique in the United States, where diesel engines historically employ a cast iron or, more recently, a compacted graphite iron (CGI) engine block for the material’s favorable strength characteristics. At 72 degrees, the engine’s cylinder configuration is relatively narrow. The combined result is an engine that is both compact and lightweight. Its small displacement and sophisticated exhaust aftertreatment system not only meets strict regulations in the U.S., but grants the engine a ULEV (ultra-low emissions vehicle) certification in most, if not all designated localities.
