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.

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.
