Red Bull has launched a protest against rivals Mercedes over its use of its Dual Axis Steering (DAS) system during Friday practice at the Austrian Grand Prix.
Mercedes caught the attention of the F1 paddock in testing earlier this year when it first ran the system that allows the driver to change the alignment -- or toe angle -- of the front wheels while the car is on track. It is operated by moving the steering wheel back and forth, although Mercedes has not responded to speculation over how it impacts performance.
The system, which has already been outlawed in the 2021 regulations, was used by Mercedes in the opening practice sessions for this weekend's Austrian Grand Prix, reigniting the debate over its legality.
