Price comparison fuel/motorisation
Standardised price comparison of conventional fuels and alternative fuels
Simple and easily comparable information on the prices of different fuels can play an important role in enabling vehicle users to better assess the relative costs of different fuels available on the market. For this reason, the European Commission has developed a method to display the unit price of different fuels at refuelling stations.
European Commission Implementing Regulation (EU) 2018/732 of 17 May 2018 establishes a common methodology for comparing the unit prices of conventional fuels and alternative fuels, which will apply in all Member States from 7 December 2020. In order to develop recommendations for the harmonised use of price comparison information, the European Union has set up an action to support the programme under the Connecting Europe Facility.
Fuels covered
Only fuels and alternative fuels available in Luxembourg are taken into account and displayed on the unit price comparison sheet.
The fuels currently covered are:
- Compressed natural gas (CNG)
- Diesel (B7)
- Electricity
- Hydrogen (H₂)
- Liquefied natural gas (LNG)
- Liquefied petroleum gas (LPG)
- Petrol - 95 octane (E10)
The list will be adapted according to the marketing of alternative fuels or combustibles in Luxembourg.
Calculation method
In order to compare fuels whose units of measurement are fundamentally different (litres, kilograms, kilowatt hours, etc.), an estimated price is calculated for each fuel, taking into account the cost of refuelling for a 100 km journey. The calculation method for each fuel is as follows:
Estimated price (Euro/100 km) = vehicle consumption (fuel unit/100 km) x fuel price (Euro/100 km)
Comparison of fuel prices by motorisation
Reference period: July 2026
| Logo | Fuel | Estimated price |
|---|---|---|
 |
Petrol 95 octane | 10,90 €/100 km |
 |
Diesel |
10,95 €/100 km |
 |
Liquefied petroleum gas (LPG) | 5,14 €/100 km |
 |
Hydrogen (H2) | 11,08 €/100 km |
 |
Electricity | 5,00 €/100 km |
Estimated prices in the context of European Commission Implementing Regulation (EU) 2018/732 of 17 May 2018
Vehicle consumption
Vehicle consumption' is calculated on the basis of the combined consumption measured according to the WLTP test cycle of new registrations in Luxembourg. From 2026 onwards, the average fuel consumption will be calculated based on the consumption of all vehicles newly registered in the previous year, grouped by engine type.

Fuel price
The "fuel price" taken into account is the average price observed over a monthly period.
For the various fuels, the data comes from:
Petrol/Diesel/LPG: https://data.public.lu/en/datasets/economie-totale-et-prix-prix-prix-de-lenergie/
Electricity: https://data.public.lu/en/datasets/comparaison-des-prix-de-carburants-par-motorisation/
Since electric vehicles are typically charged at private charging stations, especially at home, 80% of the time, the estimated electricity price is calculated as follows:
- 80%: Electricity price for residential customers;
- 15%: Average price of public AC charging stations;
- 5%: Average price of public DC charging stations.
