The 3.5-litre inline 6 diesel engine, OM 603.97x in 300 SD TURBODIESEL (1991–1993) and S 350 TURBODIESEL (1994–1996) was at last offered outside North American and Japanese markets for the first time. This engine was replaced in 1996 by all-new 24-valve OM 606.961 ERE engine. This engine was loosely derived from M 104 petrol engine with different crankshaft and cylinder head. The smaller engine fitted to S 300 TURBODIESEL put out 130 kW (177 PS; 174 hp) and 330 N⋅m (243 lb⋅ft). The fuel was delivered indirectly in the precombustion chamber before entering the combustion chamber.
