FIA taking action against Mercedes 'DAS' system

The FIA has already moved to outlaw Mercedes' new innovative DAS system from Formula 1 in 2021.

The reigning Formula 1 champions unveiled a unique concept on the second day of pre-season testing at Barcelona's Circuit de Catalunya on Thursday, entitled the 'dual-axis steering'.

The device, which allows the steering wheel to be pushed and pulled, alters the toe angle of the front wheels and its deployment along a track's straights allegedly provides a degree of additional speed.

Mercedes technical director James Allison confirmed after DAS became public that the team had been in contact with the FIA for a considerable period of time to ensure its legality.

Motorsport's world governing body has so far deemed the concept legal, as it plays no part in affecting the suspension, which is strictly controlled by the current regulations.

For 2021, however, the FIA has seemingly closed what it perceives as a loophole in its regulations.

A regulation within Article 10.5 for next year states that "The realignment of the steered wheels, as defined by the position of the inboard attachment of the relevant suspensions members that remain a fixed distance from each other, must be uniquely defined by a monotonic function of the rotational position of a single steering wheel."

A team could yet protest the legality of DAS for this year following scrutiny ahead of the season-opening Australian Grand Prix in mid-March.
