Why do Indy cars have 22-gallon fuel tanks?

“When the cars ran on methanol tanks had to hold 30 gallons to accommodate the fuel requirements of the cars,” Vervynckt says. “After getting the engines to perform at their full potential, there was a significant gain in mileage. Indy cars now have 22-gallon tanks.
