Race Fuel Consumption Calculator

Summary

This tool measures how much fuel a car burns relative to distance, not how much fuel to load before a race. Enter the fuel consumed during a stint along with the laps or distance covered, and it converts that into a consumption rate: fuel per lap, fuel per kilometer, fuel per mile, and the equivalent distance-per-fuel-unit economy figure. Race engineers use this rate to build a fuel strategy for later stints once it is known.

How it works

1. Choose your fuel unit, liters or US gallons.
2. Enter the total fuel used during the stint or session.
3. Choose whether you tracked laps or a raw distance, then enter the value.
4. The calculator converts the input into a consumption rate as you type.
5. Read the rate per lap, per kilometer, per mile, and the fuel economy figure.

Use cases

• Work out liters or gallons burned per lap after a practice session.
• Compare fuel consumption rates between two different setups or fuel maps.
• Convert a known fuel burn into a per-kilometer or per-mile rate for a road rally.
• Check whether a car is meeting a target consumption rate for endurance racing.
• Turn logged stint data into a rate that feeds a separate fuel-load plan for the rest of the race.
• Track how consumption rate changes as tire wear or fuel load drops through a stint.
