Until 2023, Total is the official fuel supplier for the FIA World Endurance Championship (WEC), which includes the 24 Hours of Le Mans, a legendary race during which we will be providing close support for our partner teams.



Through this strategic partnership with the ACO, the Group is building on its longstanding commitment to endurance racing. Like an open-air test lab, the track represents a key source of innovation, because the demands of endurance racing – long race times and distances – push us to develop increasingly high-performance fuels that will one day be available to motorists.

The ACO has recently redefined the rules for the WEC, introducing stricter constraints. Now, the objective is to achieve the best performance while minimising fuel consumption. This revolution reflects the current concerns of both manufacturers and motorists: consuming less and reducing their environmental footprint.

To meet these requirements, our engineers have developed a new unleaded FIA WEC fuel, which includes 20% ethanol from renewable sources (plant waste) and delivers increased energy efficiency. This high-octane WEC fuel (RON* of 105) also makes it possible to optimise both compression ratios and ignition settings for turbocharged engines, improving their output (ratio between mechanical power generated and thermal power consumed) and increasing their longevity.

For 24 Hours of Le Mans 2019, TotalEnergies successfully distributed 280,000 litres of this fuel to the 62 cars taking part. And throughout the race, as requested by the ACO and FIA, we carried out more than 150 fuel compliance tests in the various competitors’ garages.

In the LMGTE Pro (Le Mans Grand Touring Endurance) category, Aston Martin Racing benefits from our expertise for its engine oil and gearbox lubricant. Throughout the season, exclusive to the FIA WEC, Total deploys a mobile test lab to analyse the metals contained in the lubricants and provide real-time engine and gearbox assessments.

In the LMP2 (Le Mans Prototype 2) category, we are also supporting our partner team: Signatech Alpine Elf. And our efforts have paid off, with the team winning the LMP2 event at 24 Hours of Le Mans 2019 and securing a second FIA WEC world title.
