M 275 / M 285
Manufacturer:	Mercedes-Benz / AMG
Production period:	2002-2013
Style:	V , twelve-cylinder
Engines:	5.5 liters (5513 cc) 6.0 liters (5980 cc)
Previous model:	M 137
Successor:	M 279

The M 275 is a gasoline engine with twelve cylinders in V-arrangement and twin turbochargers of the brand Mercedes-Benz . It was first introduced in 2002 in the S-Class 220 series and gradually replaced in most models its predecessor M 137 . End of production ended in 2013, the M 275 was replaced by the M 279 . The engine was used in the S-Class , the SL and the CL Coupe .

Technology

Like its predecessor, the M 275 has one camshaft per cylinder bank and one exhaust valve per cylinder and two intake valves that are actuated by aluminum roller rocker arms and two spark plugs that are actuated with a time delay. The biggest difference to its predecessor, in addition to the slightly reduced engine capacity, is the twin-turbo charging system, which was first installed at Mercedes-Benz in a twelve-cylinder engine .

The production version of the M 275 delivers with 5.5 liters of displacement between 367 kW (500 hp) and 380 kW (517 hp). The maximum torque available is between 800 and 830 Nm. Due to this high torque, the engine is coupled to a five-speed converter gearbox designed for higher input torques and was not offered with the 7G-Tronic transmission.

M 275

AMG offered the engine as a six-liter version with 450 kW (612 hp). The torque is electronically limited to 1000 Nm to avoid gear damage. It would be possible according to Mercedes-Benz over 1100 Nm. This engine is also used in the Maybach 57 S and 62 S, but at the end of 2009 the Maybach Zeppelin also presented a more powerful version with 470 kW (640 hp). The same performance level is used in the facelifted CL at the end of 2010. The maximum torque is still 1000 Nm there.

Technical data M 275 E 55 AL (C 216)

V12 petrol engine with twin turbocharging and intercooling
Bore × stroke: 82 mm × 87 mm
Displacement: 5513 cc
Injection: Intake manifold injection
Power: 380 kW (517 hp)
Maximum torque: 830 Nm

The Mercedes-Benz M275 (and similar M285) engine is a twin-turbocharged and intercooled, all-aluminum, 60° V12 automobile piston engine family used in the 2000s (decade). It is loosely based on the M137 naturally aspirated V12 sold between 1998 and 2002, and retains its SOHC, 3 valve per cylinder, twin-spark ignition layout, but differs with the addition of structural reinforcements to the engine block for improved rigidity which in turn yields greater reliability. Bore is 82 mm and stroke is 87 mm giving a displacement of 5.5 L (5513 cc). Output is 493 hp (373 kW) at 5000 rpm with 590 ft.lbf (800 Nm) of torque at 1800-3500 rpm.
