Race Fuel Calculator
Plan your race strategy with accurate fuel calculations based on your real driving data.
Enter your average lap time, total race duration, and fuel burn rate per lap.

The results screen shows your one-lap pace, fuel consumption per lap, total race duration, and required fuel.
Endurance Calculator

Enter your average lap time, maximum stint length, and fuel burn rate to instantly see how much fuel is required for each stint. Optimize pit stop timing and maximize your time on track during endurance events.
