What is Mercedes' DAS System?

 Although it is not noticed much in daily use, the front wheels of the vehicles are placed at an angle called the toe. When we sit at the wheel and look ahead, the ends of the front wheels point slightly outwards to our left and right.

The reason this is done is because when the vehicle takes a corner, the wheels automatically compensate for this angle and are in the same plane as the rear wheels. If this angle were given to the other side, the front wheels would turn more inward than the rear wheels at cornering times, and the vehicle's handling characteristics would decrease. Changing these angles in daily traffic is not important since high speeds are not reached, and the structure of the tires is designed in accordance with this angle. But in races like Formula 1, speed starts to play a crucial role. Being fast means winning the race. Mercedes engineers have developed a system called DAS that allows toe angles to be intervened from the steering wheel. When the driver pushes the steering wheel forward - that's not a very long distance, a few centimeters - it can reset the toe angle of the front wheels. When he pulls the steering wheel towards himself, he can increase the toe angle. In this system, which ensures that the rear and front wheels can go on the same level on the flat road, the front tires of the vehicle get rid of unnecessary wear and the vehicle goes faster. In the cornering situation, the toe angles are adjusted according to the driver's request and a very controlled cornering ability is gained. While this system is operating, there is a change in vehicle height because the contact surface of the vehicle's wheels with the ground changes. While other Formula One teams are questioning whether this system is within the rules, the Mercedes team mentions that the DAS system is a completely mechanical and driver-controlled system and that the ground clearance of the vehicle changes during the cornering and straight road performances of all vehicles, and that the system they developed is within the framework of the rules.
