Claude Scruggs is number 52. He races for the team "Leakless" in the movie Cars. In the big wreck involving Chick Hicks and Winford Bradford Rutherford, he got rammed by Todd Marcus and still made it through in last place. As McQueen was about to start on his last lap, his rear was shown in the screen.
Some would say that Leak Less Adult Dripping Pans is not a prestigious sponsor, but Claude Scruggs would disagree. He's been the #52 yellow, black, and white for more than two decades, and he wears the Leak Less logo with pride. His fan base might be a bit older, but thanks to the automotive boom of the late 1940s, there are a lot of them. Their enthusiasm for the sport and for Scruggs is so intense they can barely contain themselves.
Claude is seen in the big race at the beginning of the film. He was overtaken by Lightning McQueen and spent most of the race behind No Stall's #123 Todd Marcus. When he was involved in a giant crash, he was tipped upside down by Todd and ended up getting jumped on by McQueen. The names of his pit crew are unknown, except for his crew chief (Earl Filter) and one named Stacy. He races for the team "Leakless Adult Drip Pans". He has a top speed of 160 mph.
