Calculation
R = V/v · 100
Range is inversely proportional to consumption: a vehicle using half the fuel travels twice as far on the same tank volume.
R = V/v·100 (Definition des Streckenverbrauchs in l/100 km; Dubbel Kraftfahrzeugtechnik Q 11.2 nur als Kontext)

Result
Select a target and calculate.
Understand the inputs
- Range R — Distance theoretically achievable on one full tank.
- Usable tank volume V — Fuel actually usable from the tank.
- Average consumption v in l/100 km — Average fuel consumption per 100 km driven.
Example
V=50 l and v=6.5 l/100 km give R=50/6.5·100≈769.2 km.
Assumptions and limits
Constant average consumption over the whole trip; driving style, route profile, payload, weather and the final, often unusable fuel reserve are excluded.
Understand Vehicle range from tank volume and fuel consumption
This calculator determines the theoretical range of a combustion-engine vehicle from usable tank volume and average fuel consumption, the counterpart to the existing electric-vehicle range calculators.
What does this quantity describe?
If consumption v in litres per 100 km is known, the range achievable with tank volume V follows as R=V/v·100.
Formula and variables
R = V/v · 100
R = V/v · 100
| Symbol / input | Meaning |
|---|---|
| Range R | Distance theoretically achievable on one full tank. |
| Usable tank volume V | Fuel actually usable from the tank. |
| Average consumption v in l/100 km | Average fuel consumption per 100 km driven. |
Choose the inputs correctly
V is the usable tank volume, v the average fuel consumption per 100 km driven.
How to use the calculator
Take V from the vehicle datasheet, v from the on-board computer, the rated consumption figure, or your own consumption tracking.
Worked example
V=50 l and v=6.5 l/100 km give R=50/6.5·100≈769.2 km.
Understand the result and units
Range is sensitive to consumption: a 10% reduction in consumption increases range by the same factor.
V is a volume, v a dimensionless consumption figure in l/100 km. R is output as a length.
Typical applications
Estimating range before longer trips, comparing different vehicles or driving styles, and planning refuelling stops.
Assumptions, limits and common mistakes
Constant average consumption over the whole trip; driving style, topography, payload, weather, air-conditioning use, and the often practically unusable final fuel reserve are excluded.
Common mistake: Do not take the rated consumption figure (WLTP/NEDC) uncritically as real-world range; actual consumption is often higher in everyday driving.
