New Mercedes-AMG four-cylinder turbo engine now in series production

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, claims Daimler.

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 nm. With an output per litre of up to 155 kW (211 hp), the new Mercedes-AMG high-performance turbo engine  ranks ahead of many well-known super-sports car engines, says Daimler.

The new, highly efficient powerpack is produced on an innovative production line in Affalterbach, on the “One Man, One Engine” principle.

“We already set the benchmark in the segment with the preceding engine. This fundamentally new four-cylinder presented us with the challenge of doing even better. And we succeeded with a number of sometimes revolutionary solutions,” says Tobias Moers, Chairman of Mercedes-AMG GmbH.

“With the M 139, we have once again impressively demonstrated the engine expertise of Mercedes-AMG. Not only is the output per litre unrivalled for a turbocharged engine, the high level of efficiency also demonstrates that the internal combustion engine still has further potential,” he added.

The new engine is entirely assembled by hand. On the first floor of the AMG engine manufactory in Affalterbach, a completely newly designed production line was installed in which Mercedes-AMG has brought the “One Man, One Engine” principle to a new level, together with Industry 4.0 methods that incorporate the latest findings in ergonomics, materials handling, quality assurance, sustainability and efficiency.

On the road to implementing Industry 4.0, AMG’s hand assembly operation likewise follows the vision of “smart production”.

This excels with maximum flexibility, and is transparent and highly efficient. It safeguards and improves the quality of the engines and production processes using innovative and digital technologies.

“We have completely revised the principle of “One Man, One Engine” for assembly of the M 139. The result is an ultra-modern production process that places the focus on people,” says Emmerich Schiller, COO and member of the Board of Management at Mercedes-AMG GmbH.

“To achieve this, we created the ideal working conditions in a bright, precisely organised and clean environment for our employees. This provides the best basis for continuing to ensure our high quality level even as the technology becomes more complex.”
