“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,” 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.

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 in a release.
