INDIANAPOLIS — IndyCar and Shell announced Aug. 21 that an updated formulation of Shell’s 100% Renewable Race Fuel* will be introduced for the 2027 NTT IndyCar Series season.
The new fuel, announced during a ceremony in Washington, D.C., builds on the renewable race fuel program launched in 2023 and continues IndyCar’s commitment to advancing innovation and sustainability in motorsports.
Beginning in 2027, all NTT IndyCar Series entries will compete using an updated fuel formulation supplied by Shell. The new fuel incorporates a significant portion of domestically sourced renewable ethanol produced from the waste stream of a grain mixture-based distilling process and is blended with additional renewable components to create a 100% Renewable Race Fuel*.
The ethanol feedstock used in the updated formulation will now be domestically sourced from Indiana, the home of both the NTT IndyCar Series and Indianapolis Motor Speedway. By drawing on Indiana’s rich agricultural and motorsports heritage, the program creates a powerful connection between the Heartland communities that help produce the fuel and the world-class racing that showcases it on track each May in Indianapolis and at venues across North America.
The updated fuel delivers at least a 70% reduction in greenhouse gas emissions compared to the Renewable Fuel Standard average gasoline baseline.** The fuel will continue to meet the performance and durability requirements of the NTT IndyCar Series and its engine manufacturers.
