BorgWarner BorgWarner tested the idea in the 1990s, but never produced a part for production vehicles because of high power consumption, until the
Mercedes-Benz M256 engine (2017), which used a 48-volt electrical system. , BorgWarner markets two EAT solutions: a standalone "electric compressor" (i.e. supercharger) named and a turbocharger with a single-shaft motor attached named .
Garrett Motion In October 2019,
Garrett Motion announced its first electric turbocharger for market passenger vehicles, with expected launch in 2021. The design adds an electric motor between the turbocharger's turbine wheel and compressor wheel. The 2023
Mercedes-AMG SL 43 convertible uses the
Mercedes-Benz M139 engine, which features the integrated Garrett Motion EAT.
Volkswagen TDI The
TDI line used by the Audi brand has seen
4.0 V8 TDI 310-320kW, used on the
Audi SQ7 and more. It has 2 turbochargers and 1
electric supercharger.
Volvo In 2010,
Volvo started to experiment with electrically assisted turbochargers. The result was unveiled in 2014, a 450hp 2.0L High Performance
Drive-E Powertrain Concept engine, which used a 48-volt electrical system for the electric booster. The engine has three turbos, with the electric "turbo" driving the exhaust turbines of the
twin-turbo. Despite initial reports that the
Volvo XC90 T6 would have a related improvement, only the 2016
Volvo XC90 T8 actually received a
Twin Engine starter-generator-supercharger in addition to the mechanical twincharger arrangement. In 2019, Volvo reiterated plans to replace the mechanical supercharger with an electric one.
Porsche In May 2024, the German auto manufacturer
Porsche revealed a new version of the
Porsche 911 GTS, which used a 3.6 L
flat-six engine coupled with an electric
turbocharger, dubbed the
eTurbo. The 1.9 kWh battery generates 11 kW of electrical power, and is situated directly between the turbine wheel and the engine's compressor. The
electric motor working with the transmission allows the turbocharger to spool up almost instantly, and boost pressure builds within a very short time while simultaneously reducing
turbo lag.
Torque, while not instant like in
fully electric vehicles, is produced at a much lower
RPM in comparison to the 911's gas powered models. == Related devices ==
