AMG's Cutting Edge Electric Anti-Lag System

Taking technology directly from its Formula One program, this new AMG turbo will change the science of boost forever

- Bruno Cranston

AMG is about to redefine the way we appreciate and drive turbocharged production cars, as it finalises development of a new turbo design derived straight from Formula One.

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.
