New Mercedes-AMG eTurbo technology revealed

Mercedes-AMG’s new electrically assisted turbocharger will help combat lag on the company’s upcoming, larger turbochargers

Mercedes-AMG has confirmed that its next-generation engines will feature new, electrically-assisted turbocharger technology. As well as the turbos being larger than those currently used by the company, the new units will also feature a turbine-mounted electric motor for improved response.

The technology is lifted directly from Mercedes-AMG’s Formula One team and has been co-developed with the turbocharger manufacturer, Garrett. The package consists of a large compressor, a control unit and an electric motor, measuring roughly four centimetres in diameter, which is attached to the cool side of the turbocharger.

When the control unit senses an increase in engine load, it spins the compressor wheel at speeds of up to 170,000rpm, helping the exhaust gasses to get the turbine moving and create boost. The motor will be powered by the car’s on-board 48-volt system, as fitted to Mercedes-AMG’s mild-hybrid models.

Mercedes-AMG says the electrical system can keep the turbine spinning even when the driver’s foot is off the throttle, maintaining air flow through the turbocharger during braking and mitigating lag when the power is reapplied.

The electrically assisted turbocharger is pictured mounted on what appears to be an improved version of Mercedes-AMG’s M139 2.0-litre four-cylinder petrol engine, suggesting that the company is currently developing an even more powerful version of that engine.
