Mercedes agrees to DAS system ban from 2021 onward

The World Motor Sport Council has approved a series of changes to the 2020 and 2021 Formula 1 regulations, including a ban of DAS in 2021.

Although major F1 rule changes planned for 2021 (that included a ban of Mercedes’ innovative Dual Axis Steering system) have been pushed back to 2022, essentially keeping 2020 rules for one more year, the 2021 technical regulations have been tweaked to include a new article:

“The re-alignment of the steered wheels must be uniquely defined by a monotonic function of the rotation of a single steering wheel about a single axis.

“Furthermore, the inboard attachment points of the suspensions members connected to the steering system must remain a fixed distance from each other and can only translate in the direction normal to the car centre plane.”

Considering how DAS allows drivers to change the toe angle of the front wheels by pushing or pulling on the steering wheel, the article essentially bans the use of the system.

The regulation changes have been agreed upon by all F1 teams, which means Mercedes agrees with this stipulation.
