The F1 Steering Wheel: Complete Guide to the Most Complex Technology
Anatomy, buttons, price and operation of the Formula 1 steering wheel
Introduction
The F1 Steering Wheel: The Most Advanced Onboard Computer in Motorsport
The F1 steering wheel is much more than a simple steering device. It's a true onboard command center, equipped with over 25 buttons, rotary dials and switches that allow the driver to control virtually every aspect of the car. With a price exceeding $50,000 and technology comparable to a fighter jet cockpit, the Formula 1 steering wheel represents the pinnacle of automotive engineering.
Each team designs its own steering wheel, customized according to its drivers' preferences. Engineers work closely with drivers to optimize ergonomics and control placement, because in racing, every millisecond counts when activating a function.
F1 Steering Wheel Anatomy: All Controls Explained
A modern Formula 1 steering wheel integrates dozens of controls. Here are the main functions found on most steering wheels.
Gear Shift Paddles
The paddles located behind the steering wheel control the sequential gearbox:
| Paddle | Position | Function |
|---|---|---|
| Right | Behind wheel (right) | Upshift |
| Left | Behind wheel (left) | Downshift |
| Clutch 1 | Behind wheel (lower left) | Main clutch |
| Clutch 2 | Behind wheel (lower right) | Secondary clutch |
Gear change time: 50 milliseconds (compared to 200ms for a DSG gearbox)
Main Face Buttons
| Button | Typical Color | Function |
|---|---|---|
| PIT | Green | Activates pit lane speed limiter |
| N | Red | Neutral |
| DRS | Blue | Activates/deactivates DRS |
| RADIO | Yellow | Communication with pit wall |
| DRINK | White | Activates hydration system |
| OT | Orange | Overtake mode (temporary boost) |
| MARK | Gray | Marks a point in telemetry |
| BOX | Red | Confirms pit entry |
Rotary Dials
F1 steering wheels typically feature 5 to 8 rotary dials:
| Dial | Function | Positions |
|---|---|---|
| BRAKE BAL | Front/rear brake bias | 10+ positions |
| DIFF ENTRY | Differential on corner entry | 12 positions |
| DIFF MID | Differential mid-corner | 12 positions |
| DIFF EXIT | Differential on corner exit | 12 positions |
| ENGINE | Engine mode (performance/economy) | 8-12 positions |
| FUEL MIX | Fuel mixture | 6-10 positions |
| MGU-K | Braking energy recovery | 8 positions |
Central Display
The LCD or OLED screen in the center displays:
- Engine RPM with shift light LEDs
- Engaged gear
- Lap times and gaps
- Tire and brake temperatures
- Fuel level and battery energy
- Team messages
- Flags (yellow, blue, etc.)
Advanced F1 Steering Wheel Functions
Beyond basic controls, modern steering wheels integrate sophisticated functions.
Overtake Mode (OT)
The "Overtake" button temporarily unleashes all available power:
| Parameter | Normal Mode | Overtake Mode |
|---|---|---|
| MGU-K Power | 120 kW | 120 kW (max available) |
| Engine mapping | Economy | Max performance |
| Duration | - | 3-5 seconds |
| Uses per lap | - | 1-2 maximum |
Tactic: Drivers use it at corner exit before a DRS zone to maximize acceleration.
Differential Management
Drivers constantly adjust the differential during a lap:
Corner entry: More open differential to ease turn-in Mid-corner: Adjustment based on corner type Corner exit: More locked differential to maximize traction
Brake Bias
| Circuit | Typical Brake Bias | Reason |
|---|---|---|
| Monaco | 54-56% front | Slow corners, max grip |
| Monza | 52-54% front | Heavy braking, stability |
| Singapore | 53-55% front | Bumps, grip variation |
Race adjustment: Drivers modify brake bias multiple times per lap depending on corners.

FAQ: The Formula 1 Steering Wheel
Can you buy an F1 steering wheel?
Not directly. Steering wheels are team property and aren't sold to the public. However, non-functional replicas are available ($500-2,000), and some teams occasionally sell old steering wheels at auction ($5,000-50,000 depending on driver and condition). High-end simulator steering wheels imitate F1 functionality ($1,000-5,000).
How long does it take to master an F1 steering wheel?
A professional driver typically takes 2-3 months to fully master a new steering wheel. The critical phase is learning button positions to act without looking. Academy drivers spend hundreds of hours on simulators before their first real test.
What happens if a button fails?
Every critical function has a backup. If the DRS button doesn't work, the driver can use an alternative procedure via the screen. In case of major failure, the team can sometimes fix the issue through software update. In extreme cases, the driver must pit to change steering wheels, taking an extra 20-30 seconds.
Do drivers change steering wheels during a weekend?
Rarely for preference reasons, but yes for technical reasons. If the steering wheel has a defect (faulty button, damaged screen), it's replaced. Some drivers have a slightly different "quali" steering wheel from the "race" wheel, with modes optimized for each session.
Why isn't the steering wheel round?
The rectangular/butterfly shape offers several advantages:
- More surface area for buttons
- Better screen visibility
- Reduced steering angle in F1 (180° max vs 900° on road cars)
- Optimized ergonomics for quick actions
The steering wheel is the interface between driver and machine. To understand how drivers use these controls during races, check out our articles on pit stop strategies and DRS.
