Technology
The M 275 is technically more similar to its predecessor, M 137, as the eight-and six-cylinder engines M 272 and M 273. He's like the old V12 per cylinder bank and a camshaft per cylinder, two intake and one exhaust valve, actuated by aluminum roller rocker arms, and two spark plugs which are driven at different times.
The biggest difference besides the somewhat reduced displacement, is the first time on Mercedes in the twelve-cylinder twin turbo - charging. With the power and torque values achieved thereby one could outdo the competition from BMW and Audi clearly in the introduction. Until 2009, there was neither in the A8 still in the 7 Series such a powerful engine; both reached about 330 KW (450 hp).
It is used in the current S -Class, the SL and the CL coupe.
Power values
The production version of the M 275 makes 5.5 liters of displacement between 367 kW (500 hp ) and 380 kW (517 hp). As of torque with 800-830 Nm. Due to the large forces Mercedes -Benz does not use the generally used 7- speed automatic transmission 7G -Tronic, it equips the twelve-cylinder engine with the proven five -speed automatic from.
M 275
If you find this is not enough, you can order the most powerful version of the Mercedes- house tuner AMG. The M 275 here also called motor has 6 liters of displacement and is used by the motorsport specialists to 450 KW brought (612 hp). The torque is limited electronically to 1,000 Nm to prevent transmission damage. Would be possible according to Mercedes -Benz over 1100 Nm. With this machine, well over 300 km / h in both the SL, as well as in S-Class and CL- Coupe possible, but their speed is limited at the factory to 250 km / h; on request are the AMG cars but and 300 km / h free. Also in the Maybach 57 S and 62 S, this engine is used, but here the end of 2009 in the new Maybach Zeppelin also a stronger variant with 470 KW was presented (640 hp). The same power level comes in the facelifted CL in late 2010 for use. The torque remains at 1000 Nm.

M 285
In the Maybach 57 and 62 a M 285 is called variant used. It provides with the same capacity by a modified electronics and turbochargers and other engine measures 404 kW ( 550 hp) and 900 Nm of torque.

M 158
Especially for the Pagani Huayra AMG made under the designation M 158 is a version of the M 275 with 6 liters capacity. The engine produces in this version 537 kW ( 730 hp ) and 1000 Nm of torque.
Brabus
The tuner Brabus uses the M 275 as the basis for his engine in the E V12 Brabus Rocket and. Here he makes after a displacement increase to 6.3 liters 537 kW (730 hp) and 1320 Nm torque but also limited with regard to the transmission at 1100 nm.

Future
The motor M 275 still got a further development to the M 279 to meet current legal requirements for the exhaust gas values. This enhancement is in use since 2012.
The general future of the twelve-cylinder engines can be lighter at Daimler AG after 20 years in the era of " downsizing " trend, high-revving and turbocharged engines with smaller displacement, uncertain. Claims to Mercedes 295 has set the complete redevelopment of the not yet released V12 engine M again.
Longer term, the supercharged V8 - engines of the M 278 series are able to replace the twelve-cylinder. The Maybach brand is set. What's next for the AMG models, is not yet clear.
