Mercedes-Benz M275 engine


The Mercedes-Benz M275 engine is a twin-turbocharged and intercooled, all-aluminium, 60° V12 automobile piston engine family used in the 2000s to the 2010s. It is loosely based on the M137 engine|M137] naturally aspirated V12 sold between 1998 and 2002, and retains its SOHC, 3 valves 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. The M275 V12 Bi-Turbo engine was modified with the addition of larger turbochargers. Several variations of the M275 V12 Bi-turbo engine have powered many top-of-the-range Mercedes-Benz and Maybach models since 2003.

M275

Bore and stroke is giving a displacement of. Power output ranges from to at 5000 rpm and to of torque at 1800–3500 rpm.
Applications:

M275 AMG

The first V12 from AMG was dubbed M275 AMG - a version, with boost pressure reaching at maximum, and uses air-to-liquid intercoolers. Bore and stroke are increased to. Output is or later at 4800–5100 rpm with of torque at 2000–4000 rpm. It uses an ECI ignition system for the two spark plugs per cylinder, which helps with combustion and to support Ionic current measurement function sequence. The top of the range variant fitted in the Mercedes-Benz SL-Class (R230)#SL [65 AMG Black Series (2008–11)|SL 65 AMG Black Series], which is equipped with 12% larger turbochargers, generates at 4800–5400 rpm and of torque at 2200–4200 rpm. However, due to the torque abundance to power the rear wheels, the SL65 Black is still limited to.
Applications:

M285/M285 AMG

The M285 and its AMG version of this engine built in Stuttgart, Germany specifically for Maybach badged products. Bore and stroke is. Output is at 5250 rpm with of torque at 2300–3000 rpm. The cylinders are lined with silicon/aluminium, and uses fracture-split forged steel connecting rods. The Maybach 57S and 62S received engines displacing and outputting at 4800–5100 rpm. Facelifted versions had. For the Zeppelin variant, power output rose to at 5250 rpm with 1000 N·m of torque.
Spanish sports car manufacturer Tramontana uses a 5.5-liter, twin-turbocharged M285 AMG engine in its cars. On the top model, the Tramontana XTR, it produces 653 kW and 1,100 N·m. The Tramontana C, S and R also feature this V12 in a lower output trim, with outputs ranging from.

M158

The M158 is a version based on the M275 AMG. The engine uses smaller twin scroll type turbos, a bespoke Bosch ECU, a modified intercooler configuration, and dry sump lubrication. It produces at 5800 rpm and of torque at 2250–4500 rpm. AMG builds this engine specifically for Pagani Automobili for use in the Huayra. Later, in the BC model, the M158 makes and. The Imola variant of the Huayra uses a version of the M158 producing and. The engine is mated to a new 7-speed electrohydraulic automated manual gearbox designed and built by XTrac.
