With an output of up to 310 kW (421 hp), the completely newly developed Mercedes-AMG 2.0-litre M 139 engine is the world's most powerful turbocharged four-cylinder engine in series production. With this engine, Mercedes-AMG has even exceeded the previously most powerful M 133 by 30 kW (41 hp). Maximum torque has also increased from 475 to up to 500 newton metres. With an output per litre of up to 155 kW (211 hp), the new Mercedes-AMG high-performance turbo engine even ranks ahead of many well-known super-sports car engines. The new, highly efficient powerpack is produced on an innovative production line in Affalterbach, on the "One Man, One Engine" principle.
