The American automaker has filed a patent application for an active aerodynamic system that facilitates car skidding. As a result, it will be easier for the driver to perform drift maneuvers.
As follows from the description, the on-board controller will determine the driver’s intentions to enter a controlled skid and distinguish it from an accidental slip by analyzing the steering angle and the position of the accelerator pedal. The system will then automatically adjust the aerodynamic balance between the front and rear axles, redistributing downforce to facilitate drift entry and maintain gliding.
Technically, the system will consist of moving elements – spoilers, wings or diffusers, equipped with drives. In drift mode, it will be able to reduce downforce on the rear axle, making the car more responsive to skidding.

As noted in the patent, this allows you to combine the high downforce required for fast laps on the track with its reduction for drifting.
This development could be implemented on future generations of GM sports cars – in particular, on the new Chevrolet Corvette. While most automakers use active aerodynamics to increase downforce, provide stability and lower lap times, GM’s drift-focused approach is unique in the auto industry.
