The Mercedes-Benz M 120 engine is a naturally aspirated high-performance automobile piston V12 engine family used in the 1990s and 2000s in Mercedes-Benz' flagship models. The engine was a response to BMW's M70 V12 engine, introduced in 1987. While the 5-litre BMW unit developed 300 metric horsepower (221 kW), Mercedes-Benz upped the ante considerably by creating a 6-litre, 300-kilowatt (408 PS) engine.[1]
The M 120 family was 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.[2]
The M 120 was eventually replaced by the smaller (5.8 litres), lesser-powered, short-lived, SOHC, three valves per cylinder M 137 V12 engine. Mercedes ceased production of the M 120 because of new emission rules.
E 60
[edit]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 M 120 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.

- 1992–1999 600 SEC / S 600 Coupé / CL 600 (C140)

E 70 AMG
[edit]A 7.1 litres (7,055 cc) version was also used in the SL3 70 AMG, S 70 AMG and CL 70 AMG, and produced 365 kW (496 PS; 489 hp). Another 7.1 litres (7,055 cc) version with 380 kW (517 PS; 510 hp) was used for SL 72 AMG, S 72 AMG and CL 72 AMG cars.
E 73 AMG
[edit]
There was also a 7.3 L version producing 525 PS (386 kW; 518 hp) developed by AMG which was used in the SL 73 AMG.[3] The 7.3 L M 120 engine was also featured in the AMG-built, S 73 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.[4]
M 297
[edit]In 1997, the FIA GT Championship race car Mercedes-Benz CLK GTR was fitted with the M 297 engine, derived from the M 120. The 25 road cars, required by the FIA rules and delivered in 1999, had their engine enlarged to 6.9 L.
Pagani Zonda
[edit]The Pagani Zonda has used three different capacities of Mercedes-AMG tuned versions of the M 120 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 Roadster, and back to the 6.0 L for the Zonda R and the Zonda Revolución. The bore and stroke of the 7.3 L version is 91.5 mm × 92.4 mm (3.602 in × 3.638 in).[5][6][7]
