Billy Griffin is a Bronze-graded amateur sportscar and endurance racing driver with eight seasons of professional-level competition since 2019. His career centres on Trans-Am racing, where he has contested 21 starts across eight seasons and amassed nine wins and twenty podiums; he also made a brief appearance in IMSA VP Racing SportsCar Challenge in 2023, where he scored two wins from six starts with KOHR MOTORSPORTS. Across all series, Griffin has finished on the podium in 22 of 27 starts, averaging a third-place finish, and secured one championship, the 2022 Trans-Am GT title. His Racer Rating of 3,157 places him among experienced amateur and semi-professional drivers competing in structured national and international grids.[1]
Griffin's record against more established rivals is mixed. He has faced off repeatedly against Francis Selldorff, a Silver-graded professional and former champion, finishing ahead of him twice but behind him four times across six shared races; similar head-to-head records against other Silver-graded professionals Patrick Wilmot and Sebastian Carazo, winning two races each but losing four, show Griffin as a capable but not dominant competitor at that level. He has beaten several stronger drivers in isolated results, including a single victory over Paul Menard, a former champion rated significantly higher, and victories over Silver-graded multiple champions Luca Mars, though these remain outlier performances rather than patterns of superiority. Against Bronze-graded peers and lower-rated rivals, his record is even; he finished ahead of Vincent Barletta and Angus Rogers twice and three times respectively but trailed both drivers in the same number of shared races, suggesting he is a midfield performer within his category rather than a commanding presence.[2]
Griffin remains active in Trans-Am racing into 2026, where he has scored two wins and two podiums across two contested rounds so far this season, maintaining his competitive pace in the series that has formed the backbone of his career.
