The new Formula One season is less than a day old, but Red Bull is already planning to question the legality of Mercedes' car via the sport's governing body, the FIA.
Mercedes caught the attention of the F1 paddock in testing earlier this year when it ran a novel steering system that not only steers the wheels but also changes their alignment. It is operated by moving the steering wheel back and is referred to by the team as Dual-Axis Steering, or simply DAS.
The system, which has already been outlawed in the 2021 regulations, was used again by Mercedes in the opening practice session for this weekend's Austrian Grand Prix, reigniting the debate over its legality.
