Explained: Mercedes’ DAS system and fears over what follows

There was only one talking point in the Formula 1 paddock on the second day of pre-season testing, as Mercedes debuted its dual-axis steering system.

The device is used to adjust the toe on the front wheels between the straights and the corners, but, although Mercedes said the FIA is aware of the system, it does not appear clear if it modifies the suspension while the car is in motion – which is not permitted in F1’s regulations – or steering.

In our exclusive video, Autosport’s Technical Editor Jake Boxall-Legge is joined by Technical Consultant Tim Wright, who explains what Mercedes is doing with its system and outlines his fears that ruling the device legal could open the floodgates to misinterpretation.
