IndyCar* and Shell announced today that an updated formulation of Shell’s 100% Renewable Race Fuel will be introduced for the 2027 NTT IndyCar Series season. The Renewable Race Fuel is blended from components derived from biogenic wastes and byproducts that meet the renewable fuel definition in the Renewable Fuel Standard in the Federal Law 40 CFR Part 80 Subpart M. The renewable fuel delivers at least a 70% reduction in greenhouse gas emissions compared to the Renewable Fuel Standard average gasoline baseline.

“From the beginning, IndyCar has viewed racing as a platform for innovation. This next evolution of our renewable race fuel program demonstrates the continued progress that can be made when industry leaders work together to develop high-performance solutions that help advance sustainability goals without compromising competition,” said Mark Miles, president and CEO, Penske Entertainment Corp., which owns the IndyCar series.

Since 2023, every NTT IndyCar Series race has run on Shell’s 100% Renewable Race Fuel – making it the first major U.S.-based motorsports series powered by renewable race fuel.

“The updated formulation reflects the ongoing evolution of the program and the shared vision of IndyCar and Shell to advance fuel technology through competition,” IndyCar said in a ceremony in Washington, D.C. ahead of this weekend’s Freedom 250, which will run past the U.S. Capital building. 

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,” IndyCar said.

“For decades, Shell and IndyCar have worked together to advance innovation through motorsports’ demanding testing environments. That collaboration continues today with renewable race fuel engineered to help deliver the performance and reliability required for motorsports while incorporating renewable feedstocks sourced in the United States.” – Colette Hirstius, president, Shell USA. The Renewable Race Fuel is not available at Shell retail stations.
