PDM Racing was a racing team in the IndyCar Series and USAC Silver Crown series owned by Paul Diatlovich. Almost always a low budget team and affectionately dubbed "Poor Dumb Mechanics" by Diatlovich, it was known to make the most out of mediocre equipment. The team was founded in 1996 with the inception of the Indy Racing League and ran full seasons until 2002 when rising costs forced the team to scale back to a part-time venture. The team is most known for bringing three-time champion Sam Hornish Jr. into the league in 2000. Hornish earned the team's best finish that season, a 3rd at Las Vegas Motor Speedway.

Samuel Jon Hornish Jr. is an American semi-retired professional auto racing driver. He last competed part-time in the NASCAR Xfinity Series, driving the No. 22 Ford Mustang for Team Penske in 2017.
