Sector times

Circuits divide the lap into timed sectors, usually three, and every car's lap is recorded as its sector splits. Sectors localise performance: a car strong in a circuit's high-speed sector but weak in the twisty one is telling you its aero and mechanical trade-offs out loud.

Two derived numbers matter. The theoretical best lap stacks a car's best individual sectors into a lap it never quite drove, and the gap between theoretical and actual best measures execution. Our session pages carry full sector data, which is also what powers sim-racing comparisons against the real field.
