How it works

This ACC fuel calculator helps you determine exactly how much fuel to put in the car before the start of the race. By analysing your race length, lap times, and fuel consumption, it creates a pit stop strategy to ensure you never run out of fuel on the final lap.

To get the most accurate result:

  • Enter the Race Length set by the server.
  • Input your average lap time from practice or qualifying.
  • Check your Fuel per Lap in the ACC HUD (press [Real Time] button to see usage).
  • Use the Recommended (Safe) fuel figure when refuelling.

Where to find average fuel consumption per lap

In Assetto Corsa Competizione, you can find this data easily during a practice session. Drive 5–10 laps at a consistent race pace. Open the Real Time app on the top screen of the HUD and look at the "Avg Lap" fuel consumption figure. This gives you a precise reading for your specific car and track combination.

Accuracy & assumptions

This calculator assumes constant fuel consumption. However, in ACC, fuel load affects weight, which slightly increases consumption and decreases lap pace at the start of a stint compared to the end. The "Safety Buffer" option is designed to account for these variables, as well as Safety Car periods or Formation Laps.

Worked Example

Sprint Race Scenario

Inputs: 30 minute race, avg lap time 1m 45s, 2.7 litres per lap, 100L tank.

Result: The calculator determines you will complete approximately 18 race laps. With a 2-lap safety buffer and formation lap, you need 57.2 litres (Safe). This fits easily in one tank, requiring 0 pit stops.

FAQs

How do I calculate fuel for an ACC race?
Use the calculator above by entering the total race time or laps, your average lap time, and fuel consumption per lap. It will automatically calculate the total fuel needed, including a recommended safety buffer.
What is a good safety buffer for fuel?
A standard safety buffer is 2 to 3 litres, or roughly 1 to 2 extra laps. This covers Formation Laps, in-laps to the pits, and slight pace variances. Use the "Advanced" options to set this precisely.
Does fuel load affect lap time in ACC?
Yes, a heavier fuel load makes the car slower. A full tank (100L) can add roughly 1–2 seconds per lap depending on the track. Our calculator uses your average lap time input, so ensure this represents a realistic race pace, not just an empty qualifying lap.
Why does the tool recommend "Safe" fuel over "Minimum"?
Minimum fuel is the exact mathematical amount required to finish the distance. Running minimum fuel is risky because yellow flags, safety cars, or formation laps consume extra fuel. The Safe estimate ensures you finish the race comfortably.
How do I plan pit stops for endurance races?
Select "Endurance" preset or increase your safety buffer. The tool will calculate how many litres fit in your tank per stint and suggest the number of pit stops required to cover the total race distance.
Does this account for the Formation Lap?
By default, no. However, you can toggle the "Formation Lap (+1)" option in the Advanced section to automatically add one lap's worth of fuel to your calculation.
