| Successor | M137 |
The Mercedes-Benz M120 engine is a naturally aspirated high-performance automobile piston V12 engine family used in the 1990s and 2000s in Mercedes' flagship models.
The M120 family is built in Stuttgart, Germany. It has an aluminium engine block lined with silicon/aluminium. The aluminium DOHC cylinder heads are 4 valves per cylinder designs. It uses sequential fuel injection (SFI) and features forged steel connecting rods.
The M120 was eventually replaced by the smaller, lesser-powered, short-lived, SOHC, three valves per cylinder, 5.8L, M137 V12 engine. Mercedes ceased production of the M120 because of new emission rules.
M120 6.0 48v
This engine developed 394–408 PS (290–300 kW; 389–402 hp) and 420–428 lb⋅ft (569–580 N⋅m) of torque for the 6.0 L version. In 1992 only the M120 engine was offered in North America in 402 hp (300 kW; 408 PS) format and from 1991-92 408 PS (300 kW; 402 hp) In Europe. All other years 1993–1999 have the 394 PS (290 kW; 389 hp) version.
Applications:
- 1992–1999 600 SEC / S 600 Coupé / CL 600
- 1991–1998 600 SE / 600 SEL / S 600
- 1992–2001 600 SL / SL 600
Larger displacement M120s
In 1997, the FIA GT Championship race car Mercedes-Benz CLK GTR was fitted with the M297 engine, derived from the M120. The 25 road cars, required by the FIA rules and delivered in 1999, had their engine enlarged to 6.9 L. There was also a 7.3 L version producing 525 PS (386 kW; 518 hp) developed by AMG which was also used in the SL73 AMG, S73 AMG and CL73 AMG. The 7.3 L M297 engine was also featured in the AMG-built, S73 T Kombi, a custom-built W140 S-Class wagon for the Sultan of Brunei. Eighteen units were produced, ten of which went to the Sultan.[1]
A 7.1 L (7,055 cc) version was also used in the SL70 AMG, S70 AMG and CL70 AMG, and produced 496 PS (365 kW; 489 hp).
Another 7.1 L (7,055 cc) version with 510 PS (380 kW; 500 hp) was used for SL72 AMG, S72 AMG and CL72 AMG cars.

The Pagani Zonda[2] has used 3 different capacity, Mercedes-AMG tuned, versions of the M120 engine starting with the untuned 6.0 L for the original Zonda C12 to a 7.0 L version for the C12-S and Zonda GR, then to the 7.3 L for the Zonda S 7.3, Zonda F, Zonda Cinque and the Zonda Tricolore, and back to the 6.0 L for the Zonda R and the Zonda Revolucion. The bore and stroke is 91.5 mm × 92.4 mm (3.60 in × 3.64 in).[3]
