How many buttons and switches does an F1 steering wheel have and what do they do?
Our 2019 steering wheel has a total of 25 buttons and switches and, of course, the clutch and the shift paddles. Five of those buttons and switches change the brake settings of the car: the driver can shift the brake balance from the front to the rear or vice versa, to optimise the brake balance for an individual corner, change the amount of engine braking or adjust the brake migration, which is a dynamic change of the brake balance depending on how hard the driver brakes.
Another three switches control the differential - the amount of torque transfer between the rear wheels - for the entry, the apex and the exit of a corner. The rest of the buttons and switches have a variety of different purposes, from adjusting the settings of the Power Unit to changing the data that is displayed on the screen, activating the radio or the pit lane speed limiter.
The Drag Reduction System (DRS), which will have an even stronger effect in 2019 due to the bigger rear wings, can also be activated at the push of a button.
