F1 Circuit Maps: Speed, Braking and G-Force

About this chart

What it shows. The layout of the circuit traced from the session's fastest lap, drawn nine times with the track coloured by a different measurement each time: speed in three colour schemes, braking, throttle, elevation, and longitudinal, lateral and vertical acceleration.

How to read it. Each map is the car's path seen from above, rotated to the circuit's usual orientation, with corner numbers in black circles. The colour bar at the top gives the scale: speed in km/h, throttle in percent, elevation in metres, acceleration in g. Braking has only two colours because the brake signal is simply on or off. Each scale runs from that lap's lowest value to its highest, so the middle colour is not zero.

What to look for. On the speed maps, the darkest corners are the slowest and decide the gear ratios and downforce level. The braking map shows how short the braking zones are compared with the full-throttle map. The elevation map reveals climbs and drops that a flat layout hides, such as Spa's Eau Rouge or Austin's Turn 1 hill, and the vertical acceleration map highlights crests and compressions.

Data and caveats. Position and car telemetry of the session's fastest lap from the official F1 timing feed, processed with FastF1 and published by TracingInsights; corner positions come from the same source. The acceleration channels are calculated from speed and the car's path, not read from sensors, and all nine maps describe one lap only.
