On Episode 51 of Inside ChampCar -- we talk with Frank Rehnelt about the new ChampCar F-Class. It's a deep dive into the motivation behind the new class, and we talk about some of the cars that are eligible. We also have our tech tip and you'll want to take some notes. Then we look ahead to the National Championship race at Road Atlanta... and there's a pretty solid team that didn't qualify for the big dance.
