Garrett E-Turbo marks the evolution of electrically-assisted boost

Garrett Motion, the well-known purveyor of turbochargers since 1950, has gone public with its E-Turbo, the evolution of the electronically assisted turbo. As Forbes explains, the unit puts an electric motor on the shaft between the turbine wheel and the compressor, which is different from how electronically boosted turbocharging systems in vehicles from Mercedes-Benz and the Volkswagen Group work. Garrett engineers told a conference that when compared to a standard, modern Garrett turbo, they've seen up to a 16% increase in rated power, and a 10.5% increase in rated torque.
