Bob Michaelian is a Bronze-rated endurance racing driver competing in IMSA series since 2020. His Racer Rating of 3,707 places him in the semi-professional band; this level describes drivers who win in pro-am and one-make classes and run mid-pack among full professionals. Michaelian has logged 47 starts across IMSA Pilot Challenge, IMSA VP Racing SportsCar Challenge, and Trans-Am, recording one win and seven podiums with an average finishing position of P13.3. He has raced primarily for KOHR MOTORSPORTS, which holds 44 of his starts.[1]
Michaelian's record against regular rivals shows a competitive mid-pack presence in endurance racing fields. Against Sean Quinlan, a fellow Bronze-graded driver, Michaelian finished ahead 25 times to 19 behind across 44 shared races. He held a slight advantage over Gregory Liefooghe, another regular competitor, with 23 wins to 21 losses in 44 races. Most tellingly, Michaelian finished ahead of Stevan McAleer, a Gold-graded professional driver, on 33 occasions across 42 shared races; this pattern suggests Michaelian is reliable and competitive in mid-field endurance racing, though he trails the stronger drivers in the field. Against higher-calibre rivals such as Matt Plumb, the 2024 IMSA Pilot Challenge GS champion, Michaelian finished ahead 24 times to 19 behind, indicating he can hold his own against a championship-level competitor on individual occasions rather than as a pattern.
Michaelian's single win came in IMSA VP Racing SportsCar Challenge in 2023 or 2024. His most recent start was a podium finish in Trans-Am in 2022. The body of his work sits firmly in the endurance racing category where his Bronze grading applies; he has occasionally finished ahead of much stronger drivers from single-seater and stock car backgrounds when their paths have crossed in IMSA events, but these remain isolated results rather than evidence of movement up the grid.
