Bob Michaelian is an entry-level professional competing in multiclass endurance and sprint racing across IMSA's national championships and Trans-Am, rated 3,547. He races GT4-specification production-based sports cars in IMSA Pilot Challenge and IMSA VP Racing SportsCar Challenge for KOHR Motorsports, a small team that has fielded 18 drivers across multiple series. Graded FIA Bronze, he competes alongside established professionals and semi-professional regulars in fields mixing amateurs through to graded drivers.[1]
Over six seasons from 2020, Michaelian has made 47 starts in IMSA Pilot Challenge, recording four podiums in its GS class. His most significant results came in IMSA VP Racing SportsCar Challenge, where he took a win and two additional podiums across three starts in 2023 and 2024, racing in the GSX class. A single Trans-Am start in 2022 yielded a podium and a fourth-place championship finish. His total across all series stands at 51 starts, one win and seven podiums.[2]
Michaelian races regularly against entry-level professionals of comparable standing: Gregory Liefooghe, graded FIA Silver with substantial experience across IMSA Pilot Challenge and VP Racing SportsCar Challenge, and Sean Quinlan, Bronze-graded like himself, who has run NASA regional racing alongside his IMSA starts. Against this peer group Michaelian runs closely matched. His single starts against much stronger opposition, the 2016 ARCA champion Chase Briscoe and the 2020 NASCAR Xfinity champion Austin Cindric, produced one podium each, results that reflect the occasional opportunity against established drivers rather than a consistent pattern.
