M157 Engine Technical Data
The M157 is the second variant of the M278 and is tuned by Mercedes-AMG with a bore and stroke of 98 mm × 90.5 mm (3.86 in × 3.56 in) for use in higher-performance models.
There are six states of output with the M157
For the S-Class and CL-Class, power is 400 kW (544 PS; 536 bhp) at 5,500 rpm with 800 Nm (590 lb-ft) of torque at 2,000-4,500 rpm, or 420 kW (571 PS; 563 bhp) at 5,500 rpm with 900 Nm (664 lb-ft) of torque at 2,500-3,750 rpm with AMG Performance Package.
For the 2013-15 SL-Class, power is 395 kW (537 PS; 530 bhp) or 415 kW (564 PS; 557 bhp) with the optional AMG Performance Package.
For the 2012-2013 E-Class and CLS-Class, power is 386 kW (525 PS; 518 bhp) with 700 Nm (516 lb-ft) of torque in standard tune, or 410 kW (557 PS; 550 bhp) with 800 Nm (590 lb-ft) of torque with the AMG Performance Package.
Beginning with the 2014 E-Class and CLS-Class, power increases to 410 kW (557 PS; 550 bhp) 720 Nm (531 lb-ft) of torque for standard tune, or 430 kW (585 PS; 577 bhp) with 800 Nm (590 lb-ft) of torque for "S-Model" variants.
These engines are mated to the AMG Speedshift MCT 7-speed semi-automatic transmission, which replaces the 7G-Tronic's torque converter with a wet clutch pack. Note that this MCT 7-speed can handle considerably more torque and is not the same unit as the dual-clutch transmission found on the Mercedes-Benz SLS AMG.
AMG 63 BiTurbo (M157)
The direct injected and twin turbocharged 5.5 liter M157 V8 AMG engine produces 544 HP and 800 Nm (590 lb-ft) of torque.
