Grand Prix Telemetry & Race Engineering Reference
The Mechanics of F1 Stint Planning
Completing consecutive Grands Prix in modern Formula 1 requires balancing fuel burn-off (gaining approximately 0.033s per lap as 105 kg of fuel burns) against cumulative tyre thermal degradation.
When tyre rubber wears and overheats beyond its working thermal window, degradation accelerates exponentially—creating the strategic "tyre cliff". Drivers adjust engine modes, lift-and-coast, and corner entry angles to balance lap time against tyre conservation.
How Undercut vs. Overcut Works
An undercut occurs when a car pits 1-2 laps earlier than rivals to fit fresh tyres, using the immediate 1.5s - 2.0s pace advantage on warm rubber to jump ahead once the competitor stops. An overcut is preferred when tyre warm-up is slow or fresh tyres suffer early graining.
Tyre Compounds & Pirelli Characteristics
Pirelli allocates three dry compounds per Grand Prix weekend selected from C1 (hardest) to C5 (softest).
- Soft (Red C4/C5): Fastest instantaneous grip (+0.8s vs Hard), but higher thermal degradation (0.12s/lap).
- Medium (Yellow C3): The versatile starting compound, balancing attack phase with a stable 20-25 lap window.
- Hard (White C1/C2): Robust, low degradation (0.04s/lap), ideal for executing one-stop strategies and covering safety cars.
Safety Car & VSC Pit Windows
Under a Virtual Safety Car (VSC) or full Safety Car (SC), the entire grid is restricted by delta times. Because cars on track travel ~40% slower, the relative time lost during a 20-second pit stop drops from ~22s down to ~11s, offering a "cheap pit stop" that alters the optimal strategy.
