At a glance
Public F1 telemetry graphics can show how speed, gear, steering, throttle, braking and time delta vary across a lap. They are selected views, not a public feed of a team’s complete data.

What a lap trace can show
Telemetry is measurement sent from the car while it is running. The FIA’s 2024 Formula 1 Technical Regulations, Issue 4, Article 8.6, require a car-to-team telemetry system and prohibit team-to-car telemetry, except the FIA marshalling system and link handshaking. This tells us about the permitted direction of the regulated telemetry link; it does not publish the teams’ full channel lists or make their live data public.
A reader-facing example is Formula 1’s comparison of Lewis Hamilton and Max Verstappen at the 2021 Bahrain Grand Prix. Its graphic stacks gear, steering input, speed, throttle/brake and a time-delta trace for selected laps. The authors use those traces to discuss particular corners and a time difference. That is an editorial example tied to a specific event, not a standardized public dashboard supplied for every lap.
Read traces together, then ask what is missing
| Trace | Useful first reading | Limit without more context |
|---|---|---|
| Speed | Where the displayed car slows, accelerates or reaches a local minimum along the graph | Does not identify the cause: line, grip, traffic, setup and conditions can all matter |
| Throttle / brake | How the displayed pedal traces change relative to speed and corner phases | Published graphics may simplify or normalize signals; they do not reveal every control or pressure channel |
| Gear | Gear changes and the gear selected through a displayed portion | Not a standalone measure of engine performance or driver skill |
| Steering input | Direction and relative changes in the displayed steering trace | A trace alone does not establish balance, tyre state, grip, or the driver’s intent |
| Time delta | Relative time gained or lost between two selected laps at the points shown | Depends on the chosen reference lap, synchronization and distance axis; not a universal lap-time measure |
A disciplined comparison
Start by checking which cars, laps and session the graphic compares. Then read traces at the same horizontal position: a speed change may coincide with a brake input, gear change or steering adjustment. An F1 writer may interpret those aligned changes using video, team comment or other context. A reader should keep that interpretation attached to the cited lap and corner instead of generalizing it to a driver’s entire style.
The Bahrain article, for example, reports that Hamilton lost time at Turn 10 in a particular qualifying comparison and points to steering correction and throttle timing in the displayed traces. That is a case-specific explanation by F1’s data team. The graphic itself cannot establish every causal step without supporting evidence and the article’s expert interpretation.
Why live data access is limited
Telemetry displays also omit context unless the publisher supplies it. A speed trace alone does not reveal the driver’s target, setup, tyre condition, fuel, deployment mode or traffic. Even when throttle and brake channels are shown, the reader sees selected signals rather than the complete engineering state of the car.
Telemetry is also time-dependent: a trace sampled from one lap cannot automatically be compared with a different tyre age, fuel load or track state. Before drawing a conclusion, identify the session, lap, car configuration and displayed channels. Those labels determine what the plot can support.
The regulations define the car-to-team link and its direction, while FIA technical oversight also requires standardized systems. The article cited here is a public presentation of selected comparative measurements. It is not an invitation to infer access to confidential team channels such as complete sensor histories or setup files. The public traces are useful precisely when their scope is stated.
So telemetry can help answer “where did these two displayed laps differ?” It cannot, by itself, answer “which driver is always faster through this kind of corner?” or “what was the precise mechanical cause?” Those claims require a defined sample, comparable conditions and evidence beyond one plot. For another way to compare evidence carefully, see our Teammate Comparisons hub and Technology hub.
