Everything you need to know about an F1 steering wheel

Since the early days of F1 in the 1930s, the steering wheel has continuously evolved to become an essential device that does much more than simply steer the wheels. This includes an analysis of its main components.

The steering wheel is much more than just a control device; it is the driver's control center, a compact cockpit that allows them to adjust a modern F1 car on the fly. As soon as the driver grasps it, a cascade of lights, paddles, and switches informs them of every decision made in a fraction of a second. A ring of three LED lights frames each side of the screen, mirroring the flags on the track. When a yellow flag appears, the corresponding LEDs light up yellow, providing an instant visual signal that a caution is in effect. Above the screen, fifteen additional lights serve as a rev indicator: the first five turn green when the engine is stabilized, the next five turn yellow as the revs increase, and the last five flash red when the rev limiter is approaching, signaling the optimal moment to shift up.

Gear changes are made using two paddles located behind the steering wheel. Pulling the left paddle shifts down, while the right paddle shifts up. Just below the first paddle is a clutch paddle that replicates the function of a pedal, which is essential in a single-seater car where there are only two pedals. The button cluster is a communication center. The “radio” button opens the line to the pit crew, but only one engineer speaks at a time to avoid confusion. The “PC” button allows the driver to confirm their entry into the pit lane without saying a word, while the “PL” (or “PIT”) button automatically limits the speed to the specific range for the circuit, between 60 and 80 km/h. Any changes to the settings are confirmed using the red “OK” button, marked with a cross.Aerodynamic aids are also at the driver's fingertips. Pressing the “DRS” button (marked “N”) activates the Drag Reduction System, a system added in 2011 to facilitate overtaking, which has increased the number of overtakes as expected, although some concerns remain. The “BOOST” or “OT” button releases the full power of the battery for acceleration in a straight line, and on certain wheels, a dedicated button recharges the battery. A “burn-out” button can be used to warm up the tires before the start to maximize grip. Brake management is equally sophisticated. The “BS” or “BBAL” dial adjusts the balance between the front and rear brakes, while the “BB+” and “BB-” buttons distribute braking force between the axles. A second dial, “BMIG,” allows for precise adjustment of brake migration, compensating for the electronic nature of the rear brakes and restoring a more natural feel to the pedal. The differential, essential for cornering, is controlled by three buttons. “ENTRY” locks the differential at the entrance to the corner, keeping both wheels rotating simultaneously. In the middle of the turn, the driver turns the “MID” button to open the differential, allowing the inside and outside wheels to turn at different speeds. When the car accelerates out of the turn, the “HI-SPEED” button brakes the differential for better traction. The engine power is not left to the car alone. The “STRAT” dial, numbered from 1 to 16, allows the driver to increase or decrease the power level according to their strategy. The central purple dial is a multifunction control that allows the driver to adjust the brightness of the screen, activate rain mode, etc. The turquoise “HPP” button controls the kinetic energy recovery system, which recovers braking energy that would otherwise be lost as heat and feeds it back into the powertrain.

Each team customizes the layout of its steering wheel, and the equipment evolves each season. Mastering these controls is essential: a single mistake can cost seconds or even lead to retirement. For the driver, the steering wheel is the ultimate interface, a dense and constantly evolving dashboard that translates strategy, engineering, and instinct into performance on the track.
