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.[1] 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.[2]

The M137 was replaced by the more powerful twin-turbocharged M275 engine.

Mercedes introduced the M137.970 engine in its 5.8-litre form in S 600 and CL 600 models. The internal measurements of NaNmm of bore and stroke translates to a total displacement of 57861NaN1. The resulting power output is 2700NaN0 at 5500 rpm and torque figures of 5300NaN0 at 4250 rpm. From 1997 up to 2002, Mercedes produced 11,693[3] examples of the M137.970-powered S 600 and further 6,348 units of the coupé version, CL 600.[4]

E63 AMG

In 2001 Mercedes and AMG introduced a series of special high-output models equipped with a larger-displacement M137.980 engine.[5] [6] Cars were available through AMG dealers only and sold to selected European and Asian customers. The 2001 S 63 AMG was produced in only 70 units. The 2001 CL 63 AMG exists in only 26 examples and the rarest of all is the 2002 G 63 AMG with only 13 units produced.[7] [8] [9] The total displacement of 62581NaN1 is thanks to internal measurements of NaNmm.[10] The resulting power output is 3260NaN0 at 5500 rpm and torque figures of 6200NaN0 at 4400 rpm.[11]
