The driver tells the GW type of intention such as running, turning and stopping, and the vehicle artificial brain performs the safest and fastest operation.
  • the downforce When the skirt is lowered, the downforce is intensified, and when it is raised, air enters from the surroundings and the negative pressure becomes weak. As the vehicle height increases, the downforce weakens and decreases. When air is turned from the central duct, negative pressure weakens. Changing the shape of the air inlet changes the inflow. If the obstacle is put out in the tunnel and the air flow is disturbed, the downforce becomes weak. Weight reduction is important for sports cars, but GW type has more than 1200 horsepower, so I want to consider other factors in a well-balanced manner. They are price, strength, ease of processing, durability etc. The GW model is an EV that pursues running, but it is also important that it is easily accessible.
