About Mercedes-Benz S420
For the entire model run, the M 120 V12 engine was only available in 6.0 litres. For the 6.0-litre version, this engine produced 290-300 kW (394-408 PS; 389-402 hp) and 569-580 Nm (420-428 lbft) of torque. The 300 kW (408 PS; 402 bhp) model was available in Europe from 1991 to 1992, but not in the United States. For lower emission control, the V12 was slightly detuned to 290 kW (394 PS; 389 bhp) in 1993. An AMG-prepared 6.0-litre M 120 V12 with a higher performance rating of 327 kW (445 PS; 439 hp) and 623 Nm (460 lbft) was available only for S- or CL-Class (C140) coupes, not S-Class sedans/saloons.
For the first time, the 3.5-litre inline-6 diesel engine, OM 603.97x, was offered outside of the North American and Japanese markets in the 300 SD TURBODIESEL (1991-1993) and S 350 TURBODIESEL (1994-1996) models. In 1996, it was replaced by the all-new 24-valve OM 606.961 ERE engine. This engine was based on the M 104 petrol engine, but with a unique crankshaft and cylinder head. The S 300 TURBODIESEL’s smaller engine produced 130 kW (177 PS; 174 hp) and 330 Nm (243 lbft). Before entering the combustion chamber, the fuel was delivered indirectly in the precombustion chamber.
