Telemetry channels are the individual data streams recorded during each lap. Each channel captures a specific measurement at high frequency, building a complete picture of what the car was doing at every point on the track.
For guidance on interpreting these channels, see Reading Telemetry.
Core Driving
| Channel | Unit | Typical Range | What It Tells You |
|---|---|---|---|
| Speed | km/h | 50–350 | Car velocity. The shape of the speed trace through corners reveals your driving technique |
| Throttle | 0–100% | 0–100 | Throttle pedal position. Shows how progressively you apply power on exit |
| Brake | 0–100% | 0–100 | Brake pedal pressure. The shape of the brake trace reveals your braking style |
| Steering | -1.0 to 1.0 | varies | Steering wheel angle. Smooth traces indicate consistent, confident driving |
| Gear | -1 to 8 | 1–8 | Current gear. -1 = reverse, 0 = neutral |
| Engine RPM | rpm | 3,000–15,000 | Engine speed. Useful for shift point analysis |
| DRS | 0/1 | — | DRS flap state (F1 only). 1 = open |
| Clutch | 0–100 | — | Clutch position. Relevant for race starts |
G-Forces & Rotation
| Channel | Unit | Typical Range | What It Tells You |
|---|---|---|---|
| Lateral G | g | -5 to 5 | Cornering force. Higher values = more grip being used |
| Longitudinal G | g | -5 to 5 | Braking/acceleration force. Negative = braking |
| Vertical G | g | 0.5–2.0 | Vertical load changes from bumps and elevation |
| Yaw | rad | — | Car rotation around vertical axis |
| Pitch | rad | — | Forward/backward tilt (braking pitches forward) |
| Roll | rad | — | Side-to-side tilt during cornering |
| Front wheels angle | rad | — | Actual front wheel steer angle |
Position & Motion
| Channel | Unit | Typical Range | What It Tells You |
|---|---|---|---|
| World Position X/Y/Z | m | varies | 3D car position on track. Used for track maps and racing line visualization |
| World Velocity X/Y/Z | m/s | varies | Speed in each world direction |
| Local Velocity X/Y/Z | m/s | varies | Speed relative to the car (X = lateral, Z = forward) |
| Lap Distance | m | 0 to track length | Distance from start/finish line. The X-axis for most charts |
| Session Time | s | — | Elapsed session time |
Tires (per wheel: FL, FR, RL, RR)
| Channel | Unit | Typical Range | What It Tells You |
|---|---|---|---|
| Surface Temperature | °C | 70–120 | Outer tire temperature. Most responsive to driving style |
| Inner Temperature | °C | 80–110 | Tire carcass temperature. Changes slowly, indicates core heat |
| Tire Pressure | PSI | 20–28 | Inflation pressure. Rises with temperature during a stint |
| Tire Wear | % | 0–100 | Remaining tire life. Track across a stint for degradation rate |
| Tire Damage | % | 0–100 | Damage from lockups, curbs, or contact |
Brakes (per wheel: FL, FR, RL, RR)
| Channel | Unit | Typical Range | What It Tells You |
|---|---|---|---|
| Brake Temperature | °C | 200–1100 | Brake disc temperature. Overheating reduces braking performance |
| Brake Damage | % | 0–100 | Brake wear from sustained use |
| Brake Bias | % | 50–65 | Front brake proportion. Higher = more stable under braking |
Fuel & ERS
| Channel | Unit | Typical Range | What It Tells You |
|---|---|---|---|
| Fuel in Tank | kg | 0–110 | Current fuel load |
| Fuel Remaining Laps | laps | — | Estimated laps at current consumption rate |
| ERS Store Energy | MJ | 0–4 | Current battery charge. Full = 4 MJ in F1 |
| ERS Deploy Mode | enum | 0–3 | Deployment aggressiveness. Higher = more power |
| ERS Deployed/Harvested | MJ | — | Energy used and recovered this lap |
Suspension & Dynamics (per wheel where noted)
| Channel | Unit | Typical Range | What It Tells You |
|---|---|---|---|
| Suspension Position | mm | -20 to 20 | Suspension travel per wheel. Shows weight transfer |
| Wheel Speed | m/s | varies | Individual wheel speed. Differences indicate slip |
| Wheel Slip Ratio | — | -0.2 to 0.2 | How much the tire is slipping longitudinally (braking/acceleration) |
| Wheel Slip Angle | rad | — | Lateral tire slip. The foundation of cornering grip |
| Ride Height (front/rear) | m | 0.02–0.10 | Ground clearance. Drops under braking (front), rises under acceleration |
Data Frequency
Telemetry is captured at the game's native output rate (typically 60 Hz) and compressed for storage:
- High tier (20 Hz) — Core driving inputs, position, velocity, g-forces
- Medium tier (5 Hz) — Temperatures, pressures, wear, ERS, suspension
- Low tier (1 Hz) — Settings, damage, compound, flags
Higher-tier channels give finer detail for fast-changing values like throttle and brake, while slower-changing values like tire wear only need infrequent sampling.
