IRL (Indy Racing League) cars use alcohol fuel, specifically ethanol, primarily for its high octane rating, which allows for better performance and efficiency in high-speed racing conditions. Ethanol also has a higher cooling effect, which can help prevent engine overheating. Additionally, using alcohol fuels aligns with efforts to promote renewable energy sources and reduce emissions, making it a more environmentally friendly choice compared to traditional gasoline.
