Report: Mercedes-AMG to employ F1 tech in new turbo inline-four


Current AMG 2.0L turbo inline-four maxed out, successor in the works

The current AMG 2.0-liter turbo inline-four will apparently be succeeded by a new turbocharged engine that may benefit from current F1 technology.

According to Motoring AU, Mercedes-AMG boss Tobias Moers has stated that the new engine is currently being developed by Mercedes-AMG High Performance Powertrains, the same group that built the 1.6-liter turbo-hybrid V6 engines used by the F1 team today.

Moers expounded on the matter, stating that the group was given the task to make it possible because of their expertise in developing Energy Recovery Systems (ERS) and Kinetic Energy Recovery Systems (KERS). This would enable them to further downsize the engine from 2.0-liters to 1.6-liters while still developing enough power.


The engine however will not benefit from electric turbochargers or from E-boost as it would mean having to add extra batteries or replace the standard 12V battery system.

"There's great limitations to the technology. Sure, we've experimented with it but it needs more power than a standard car's 12V electrical system and would need to carry extra batteries. We tried adding an electric fan to a regular turbo which gave us some advantages – but not enough got it to be worth it," said Moers.

The aforementioned engine will reportedly not only power the range-topping variant of the A-Class dubbed as the A45 (pictured above), but will also be used on several future models in the B-, CLA- and GLA-Class.

The need for a replacement engine came out of necessity as Tobias Moers said that the current 2.0-liter AMG turbo inline-four is already maxed out and that the turbo technology in it is already at its limit.

"That's it for this generation, we've squeezed everything we can and the turbocharging technology is at its very limit," added Moers.

There is no date yet on when they plan to introduce the upcoming turbo inline-four.
