Car Telemetry Data¶

CarData is the raw telemetry stream from each car. One record is one snapshot of what the car was doing at one moment in time: how fast it was going, how hard the driver was pressing the throttle, whether the brake was on, which gear, what the engine was doing, and whether DRS was open.

Records are produced at roughly 3.7 Hz — about one sample every 270 milliseconds — for the entire duration of a session, for every driver.

Fields¶

Field	Type	Unit / Range	Meaning
`date`	string	ISO 8601 UTC	Timestamp of this sample.
`session_key`	int	—	The session this record belongs to.
`meeting_key`	int	—	The race weekend (`Meeting`) this session belongs to.
`driver_number`	int	1–99	Permanent race number of the driver (e.g. 1 = Verstappen, 44 = Hamilton).
`speed`	int	km/h	GPS-derived ground speed.
`throttle`	int	0–100	Accelerator pedal position. 0 = fully off, 100 = flat out.
`brake`	int	0 or 100	Brake pedal status. Binary — F1 cars do not expose brake pressure publicly.
`n_gear`	int	0–8	Current gear. 0 = neutral, 1–8 = gear number.
`rpm`	int	0–~15 000	Engine revolutions per minute.
`drs`	int	code	DRS status code. See table below.
