Built in partnership with Garrett, the system will allow AMG to fit larger, more powerful turbochargers to its cars, without increasing the amount of turbo lag.
The new design includes a small electric motor, about 40mm in size, driving the turbo’s shaft and integrated between the turbine and compressor. This unit spools the compressor wheel before it is aided by exhaust gases to build boost.
AMG claims this system eliminates turbo lag – think of it as an electric anti-lag system. When a driver takes their foot off the throttle and begins braking, the turbocharger is able to maintain boost in preparation for when the throttle is applied again.
Along with improved response, AMG claims the system improves torque lower in the rev range.
