Vehicle route fuel margin
Estimate route consumption and usable range from recorded fuel economy.
How it is calculated
Planned distance = route × (1 + contingency fraction). Fuel = planned distance × L/100 km ÷ 100. Usable range = (stock − reserve) × 100 ÷ L/100 km.
Assumptions & limits
Use a rate suitable for load and conditions. Congestion, idling, road closures and terrain may greatly increase consumption. This does not establish a safe evacuation route. Defaults are illustrative planning inputs, not recommended minimums or a guarantee of safety.
Planning estimates only. Defaults are illustrative, not personalized recommendations. Do not use these calculations as medical, structural, electrical installation or other safety certification.
