How Mercedes-AMG Is Working Towards An Electric Future Like No Other
The future of Mercedes-AMG is turning electric – this includes combining high-efficiency with additional driving dynamics, to produce eco-conscious performance cars.
The developers in AMG are working intensively on technologies which will take electric vehicle performance to a new level.
Mercedes-AMG plan to achieve this with their innovative electric exhaust gas turbocharger.
The next vehicle generation will see the deployment of the electric exhaust gas turbocharger.
Mercedes-AMG is pressing ahead with electrification through pioneering developments, benefiting from their wealth of motorsport knowledge too.
The latest achievement already in the final stages of development, is the electric exhaust gas turbocharger, which in future will be used for the first time in a series production model from Affalterbach.
Developed in partnership with Garrett Motion, this technology comes straight from Formula 1 and resolves the conflicting goals between a small, fast-reacting turbocharger (which achieves relatively low-peak performance) and a large turbocharger (with a high-peak performance, but which can suffer from turbo lag).
The highlight of this innovative turbocharging system is a slim electric motor, measuring about 4 centimetres, which is integrated directly on the charger shaft between the turbine wheel on the exhaust side and the compressor wheel on the fresh air side.
This electronically controlled electric motor drives the compressor wheel before this accepts the exhaust gas flow.
The electrification of the turbocharger significantly improves immediate response from idle speed and across the entire engine speed range.
The previous turbo lag – the delayed response of a conventional turbocharger – is eliminated by the electric motor. The result is that the combustion engine responds even more spontaneously to accelerator pedal input, and the entire driving feel is significantly more dynamic and agile.
In addition, this electrification of the turbocharger enables higher torque at low engine speeds, which also enhances agility and improves its acceleration capability from a standstill. Even when the driver takes their foot off the accelerator or applies the brakes, the technology of the electric turbocharger is able to maintain the boost pressure at all times.
The turbocharger achieves speeds of up to 170,000 rpm, which enables a very high rate of air flow.
It can be operated via a 48-volt on-board electrical system. The turbocharger, electric motor and power electronics are connected to the combustion engine's cooling circuit to create an optimum temperature environment at all times.
Tobias Moers, Chairman of the Board of Management of Mercedes-AMG explains: ‘We have clearly defined our goals for an electrified future. In order to reach them, we are relying on discrete and highly innovative components as well as assemblies.
‘With this move, we are strategically supplementing our modular technology and tailoring it to our performance requirements.
'In a first step, this includes the electrified turbocharger - an example of the transfer of Formula 1 technology to the road, something with which we will take turbocharged combustion engines to a previously unattainable level of agility.’
Vertu Mercedes-Benz are excited for the recent innovations in vehicle performance and efficiency to reach our showrooms in the near future.
