"Mercedes-AMG boss Tobias Moers has revealed to motoring.com.au that the next-generation replacement for the current 2.0-litre turbocharged four-cylinder will be engineered in partnership with Mercedes-AMG High Performance Powertrains, the same black ops engineers that have created the current state-of-the-art petrol hybrid V6 for the Mercedes AMG Petronas F1 car.

When asked if the current car's 280kW/475Nm 2.0-litre turbo would feature any more upgrades AMG boss said: "That's it for this generation, we've squeezed everything we can and the turbocharging technology is at its very limit".

Moers said for the new engine Mercedes-AMG will cash in on its F1 team's expertise when he tasks the team, based in Brixworth, Northamptonshire, to create a lightweight, powerful four-cylinder turbo to power its future range of A-Class, CLA, GLA and B-Class models.

The ERS (Energy Recovery System) and KERS (Kinetic Energy Recovery System) found in current Formula 1 cars are expected to trickle down to the road-going A45 AMG. That will not only help it make more power and reduce turbo lag, but we may also see it reduce to a 1.6-liter turbo instead of the current 2.0-liter. It also means Moers doesn’t want to go full electric or diesel-power in an AMG model.


'The reason why we’re not doing a diesel is because for us to make one, we’d need a dedicated diesel engine and powertrain and there’s limited demand for it to justify that,' said Moers. 'Even almost three years out of production the SLS Electric Drive is still the benchmark for the electric car technology, with its pioneering tech, but there’s no sense in making another one [AMG eV].'


Moers goes on to say that there is currently no demand for a high-price, pure-electric supercar or AMG-badged cars, and he instead wants to focus on performance enhancing hybrid-systems, like the MGU-H (Motor Generator Unit – Heat) on the AMG Petronas Formula 1 car.


If you’re unfamiliar with the MGU-H, turbo boost is controlled by using the generator that sits between the turbine and compressor. It recovers energy under boost and in turn slows down the turbine speed, eliminating the need for a waste-gate. Lag is eliminated by reversing the flow of energy at the generator, turning it into a motor to spin the turbine up to speed when the exhaust can’t, and you don’t need to either retard the ignition timing or install a high-heat generating “rocket” anti-lag system. If the costs can come down to something reasonable for a street going system, AMG expects to use the MGU-H in the near future on their road cars, including the A45 AMG."

Interesting. I received a survey from AMG a few weeks back and one of the larger sections in it was around questions related to acceptance of hybrids. Might have been more enthusiastic if they had explained things in a little more detail.
