Electric Turbocharger, Mercedes-AMG eTurbo.
Mercedes-AMG has partnered with Garrett Motion to develop an electric exhaust gas turbocharger.
The manufacturer has not mentioned which model/s will receive the new turbocharger, but Mercedes-AMG claims the technology is already in the final stages of development.
It is understood that the new turbocharger is also destined to be used in a next-generation series production model from Affalterbach.
Electric motor housed within the turbine wheel on the exhaust side and the compressor wheel allows it to drive the compressor wheel.
The new turbocharger utilises a 4cm electric motor integrated directly on the turbocharger shaft, between the turbine wheel on the exhaust side and the compressor wheel on the fresh air side, to drive the compressor wheel before accepting exhaust gas flow.
The electrification of the turbocharger significantly improves response from idle speed while eliminating turbo lag.
Mercedes-AMG will install the turbocharger in a series production model from Affalterbach.
Mercedes-AMG claims the new turbocharger will also enable higher torque at low engine speeds, enhancing agility and optimising acceleration from a standstill.
The electric turbocharger can achieve speeds of up to 170,000rpm and can be operated via a 48-volt electrical system.
The turbocharger, electric motor and power electronics are connected to the combustion engine’s cooling circuit to maintain an optimised temperature at all times.
