McLaren hybrid rolling anti-lag system for faster acceleration

McLaren has filed a patent for a new hybrid technology designed to enhance acceleration while already in motion. This system, known as rolling anti-lag, is specifically adapted for hybrid powertrains.

Unlike traditional launch control, where the driver holds the car with the brakes while revving the engine, this new system operates on the move. When activated, the electric motor generates negative torque on the transmission, counteracting the engine's thrust. This allows the engine to reach optimal revs without actually accelerating the car.

Once the system is disengaged, the electric motor stops resisting, giving the car instant acceleration with minimal delay. This feature proves particularly relevant for turbocharged engines with noticeable turbo lag.

An additional potential benefit is faster energy recuperation, thanks to the electric motor operating in resistance mode. However, implementing the system will require complex calibration to prevent wheelspin and ensure safety.

For now, this remains just a patent. But if the technology goes into production, hybrid McLarens could offer even more aggressive dynamics at high speeds.
