The Mercedes-Benz M137 engine is a naturally aspirated, SOHC 60° V12 engine, with three valves per cylinder, 2 intake and 1 exhaust. It was built to replace the larger and heavier, yet more powerful, DOHC, four valves per cylinder, naturally aspirated, 6.0 L M120 V12 unit. The M137 was used briefly between 1998 and 2002 for the W220 S-Class (long wheelbase only) and C215 CL-Class.{{cite web|url=http://australiancar.reviews/mercedesbenz_M137.php|title=Mercedes-Benz M137 engine (1998-2002)|website=australiancar.reviews|accessdate=8 January 2020}} The architecture is similar to M112 and M113 engines, and is designed to match the overall dimensions of a V8 unit with undersquare internal measurements. The crankcase was cast in a lightweight alloy with "Silitec" (silicon/aluminium) cylinder liners to save weight. The M137 is 80 kg lighter than its predecessor and features cylinder deactivation technology. Both displacement variants have 10:1 compression ratio.{{cite web|url=https://motor-car.net/mercedes-engines/item/13778-mercedes-m137-v12-engine|title=Mercedes-Benz M137 V12 engine|website=motor-car.net|accessdate=8 January 2020}}
The M137 was replaced by the more powerful twin-turbocharged M275 engine.
