With an output of up to 310 kW (421 PS), the completely newly developed Mercedes-AMG 2.0-litre M 139 engine is the world’s most powerful four-cylinder engine in series production. With this engine, Mercedes-AMG has even exceeded the previously most powerful M 133 by 30 kW (40 PS). Maximum torque has also increased from 475 to up to 500 Nm. With an output per litre of up to 155 kW (211 PS), 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.
