The Mercedes-Benz OM611 engine is a straight-4 diesel engine produced by Mercedes-Benz.

It replaced in 1998 the naturally aspirated OM604 with indirect injection in the W202 C-Class and the W210 E-Class for the 1999 model year, in 102 PS (101 hp/75 kW) and 125 PS (123 hp/92 kW) powertrains.

In 1999, the displacement were reduced from 2.2 L (2151 cc, 131 cu in) to 2.1 L (2148 cc, 131 cu in) for the E-Class, and the engine were now available ind 116 PS (114 hp/85 kW) and 143 PS (141 hp/105 kW) powertrains.

It was also introduced with the facelift of the W90x Sprinter in 2000 for the 2001 model year in 82 PS (81 hp/60 kW), 109 PS (108 hp/80 kW) and 129 PS (127 hp/95 kW) powertrains, and in the W203 C-Class in 122 PS (120 hp/90 kW) and 143 PS (141 hp/105 kW) powertrains.
