Mercedes-Benz M156 engine
From Wikipedia, the free encyclopedia
The M156 is the first V8 automobile engine designed autonomously by Mercedes-Benz subsidiary Mercedes-AMG, as previous AMG engines have always been based on original Mercedes engines. The engine was designed to be a naturally-aspirated racing unit, and will also be used in a number of high-performance "AMG"-badged Mercedes-Benz models.
The M156 displaces 6.2 L (6208 cc) and shares very little with other Mercedes-Benz engine families like the M155. The bore spacing, block design, and other features are unique to the AMG engine.
Although it displaces 6.208 liters, the engine will be marketed as the "6.3" to comply with German car tax laws, which require them to be rounded up to the nearest 100 cc.
The engine uses a 102.2 mm (4 in) bore and 94.6 mm (3.7 in) stroke. Output is 375 kW (503 hp) at 6800 rpm with 630 N·m (465 ft·lbf) of torque at 5200 rpm.
The engine, however, has been uprated to produce 525 hp (and 465 ft·lbf (630 N·m) of torque) in the late 2006 S 63 and CL 63 models[1].
Mercedes has claimed it is the world's most powerful naturally-aspirated V8 engine.
