Team-BHP - An F1 Steering Wheel

Today, a steering wheel is a complex electronic device that allows the driver to control a vast amount of carsettings. The teams often assign one engineer that is responsible for its electronics and the design so that the drivers can use it comfortably. For that reason, today's handles of a steering wheel are anatomically formed and made of hard rubber that provides extra grip for the driver's hands. The main part of the wheel however is constructed, just like almost every car part, of carbon fibre to reduce its weight. The pieces used today have a pricetag of around € 23.000 each.

The manufacture of any part on a Formula 1 car is a complex process, and the steering wheel is no exception. Various lightweight materials are used for its production, including the before mentioned carbon fibre and rubber with aluminium, titanium, steel and plastic. A complete steering wheel can take approximately 100 hours to produce from start to finish.

With the average steering wheel controlling as many as 12 separate parameters on the car, there is a large number of components, buttons and switches that have to be fitted during the manufacturing process – some 120 separate items in all. Yet, despite the myriad of materials and parts that make up each completed wheel, the weight of the finished unit, as fitted to the car, is just 1.3kg
