Running with the front tires upright and straight will make sure the whole tire tread heats up more evenly. However, the angle of the tires causes uneven heating of the tires, making the inner portion of the tread hotter than the rest of the tire. Toe-out is advantageous in the corners, because the car feels more stable on turn-in. F1’s official DAS explanation article goes into even further detail as to why Mercedes would deploy this system. We can’t know what kind of a speed advantage it gives Mercedes at this point in testing, but the more straight position of the wheels and tires has the possibility of reducing drag. To sum that video above up, the three main advantages come in tire wear, tire temperature control and top speed.

The effects are best explained by ex-F1 driver Jolyon Palmer in the video. When Hamilton pulls the steering wheel closer to his body, the wheels move into a straight position, but pushing back in returns them to their traditional toe-out position. The system’s controls look simple, as the alignment of the front wheels is adjusted by the driver pulling and pushing on the steering column - it’s fairly obvious after watching the cockpit view of Lewis Hamilton doing this on camera (above).
Mercedes won’t give away its secrets, but plenty of folks have already given their two cents on how it works and the advantages Mercedes will gain. Let’s explain exactly what’s going on with the DAS system as best we can. "The re-alignment 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." In this case, the FIA has deemed Mercedes’ DAS system legal for the 2020 F1 season but illegal from 2021 and onward, according to Motorsport. Many obvious engineering tricks and innovations of the past get banned right away, as teams around the paddock complain and moan to FIA officials. Mercedes has named it DAS, an acronym for Dual Axis Steering.

If you’ve been paying attention to pre-season testing this year, then you’ve surely heard about Mercedes’ trick steering system, allowing its drivers to adjust the toe of the front wheels on the fly. The F1 YouTube channel even put together a super informative video not too long ago detailing teams’ innovations of the past, which is worth your time if you haven’t seen it already. Formula One has a long history of novel engineering tricks, all of them in the pursuit of faster lap times and an edge over the competition.
