WSK Promotion is pleased to announce a major partnership that marks a significant turning point toward sustainability in the world of karting: Aspen Group France, part of the Swedish Lantmännen group and a leader in high-purity alkylate fuels, has been chosen as the Official Fuel Supplier for all its competitions starting from the 2026 season.
The fuel chosen for WSK races will be Aspen+, an innovative high-octane competition fuel, specially formulated to guarantee maximum performance in the most demanding kart engines.
A choice for the Environment and Health
This collaboration is not just a technical choice, but a declaration of commitment to health and the environment. Since 1988, Aspen has been developing and globally distributing alkylate fuels, which are much cleaner than traditional E5–E10 fuels.
The adoption of Aspen+ in WSK competitions will bring immediate and tangible benefits:
Respect the health: Alkylate fuel drastically reduces the emission of harmful substances and aromatic compounds, limiting health risks for drivers, mechanics, technicians, all personnel working in close contact with running engines on the track and for the spectators. Aspen+ is classified as non-CMR (non-carcinogenic, non-mutagenic and non-reprotoxic).
For a better environment: Aspen+ is classified as an ecological fuel. Its chemical characteristics mean that it’s virtually free from benzene, toluene, sulphur and olefins. It has a better combustion and produces less smoke than traditional E5-E10 fuels, contributing to a cleaner motor and surrounding environment, leading to a more responsible race.
Engine protection: The extremely high purity of the fuel not only respects the environment but also produces close to no carbon deposits or resinous residues and ensures greater engine longevity and reliability.
Trusted Partner for Distribution
The distribution of the official Aspen+ fuel will be managed by Panta, a long-standing partner of WSK Promotion and a trusted distributor in the sector, guaranteeing impeccable logistic service and product availability at all WSK events.
Luca De Donno, CEO of WSK Promotion, stated: "We are extremely proud to embark on this journey with Aspen Group France and with their flagship product. The introduction of Aspen+ in our races represents a fundamental step for the future of karting. Combining the pursuit of maximum performance with ecological responsibility and health protection is our priority. We want WSK competitions to be at the forefront not only on the track but also in terms of sustainability."
Jean-François Bonin, President of Aspen Group France, commented: “The partnership with WSK Promotion, one of the most prestigious organizations in the world of karting, offers us an ideal platform to demonstrate how high performance and sustainability can coexist. Aspen+ is proof that it is possible to compete at the highest levels while reducing environmental impact and ensuring a healthier working environment for everyone.”
The agreement will begin with the 2026 season and establishes a new standard of excellence in international karting, demonstrating the commitment of WSK Promotion and Aspen Group France towards a more responsible sporting future.
