Mercedes-AMG continues to create the world’s strongest 2.0-liter engine

Still with 2.0-Liter volume, M 139 engine manufactured by AMG produces a capacity of up to 421 horsepowers, 500 Nm of torque. This is the most powerful 2.0-Liter engine block in the world today.

AMG used to please fans with the M 133 engine block equipped on A 45, CLA 45 and GLA 45 facelift previous models, producing a capacity of up to 381 horsepowers. This is dubbed the world's most powerful commercial 2.0-Liter engine block.

Mercedes-AMG just created additional M 139 2.0-Liter engine, with strength of 421 horsepowers.
However recently, engineers from Affalterbach have made the surprise again with the M 139 engine block. Still with a 2.0-Liter volume, M 139 produces a capacity of up to 421 horsepowers, holding the title of the world's most powerful commercial 2.0-liter engine block.

M 139 is equipped for the new high-performance versions of A 45 and CLA 45 generation. In addition, the torque of the M 139 engine reaches a maximum of 500 Nm, compared to 475 Nm on the old generation engine M 133. This engine is also rumored to be equipped with a high performance version of GLB.

Mercedes-AMG GLA 45 is the series equipped with the world’s strongest 2.0-liter engine.
With AMG 45's high-performance models, there will be 2 versions of AMG and AMG S. Standard AMG 45 cars will have a capacity of about 388 horsepowers and 480 Nm of torque. Meanwhile, the S version will have a maximum capacity of 421 horsepowers and 500 Nm of torque.

To achieve this remarkable achievement, Mercedes-AMG engineers have changed many details compared to the old generation of engines. The car's turbo system is installed deeper inside the engine, helping reduce the turbo lag phenomenon. Therefore, the engine needs to have 2 separate coolers, one for the body and one for the lid.

Another change inside the M 139 engine includes new internal turbo ball bearings, an 18% increase in the size of the exhaust valve, refining of the fuel transmission line, allowing the interference of the air conditioning system to cool the engine in a more effective way, increasing the compression ratio from 8.6: 1 to 9.0: 1 and optimizing the pressure of the booster to 30.5psi.

Each AMG M 139 engine is assembled by one engineer.
To ensure the most realistic driving experience, Mercedes-AMG also tweaks the brakes of the engine round at 7,200 rpm, helping the driver feel more confident when pushing the accelerator.

Still applying the philosophy of "One Man, One Engine", only one engineer is in charge of the entire engine assembly. However, in order to meet the large demand of M 139, Mercedes-AMG will rearrange this engine assembly process at the main factory. In the future, with the AMG 53 high-performance hybrid version, it will not be surprising if Mercedes-AMG can create another record.
