Hannah Greenemeier is an entry-level professional, graded FIA Silver, a rung below the two full-professional grades in sportscar racing. She races multiclass, shared-car endurance racing in the United States for Heart of Racing Team, campaigning GT4 cars in GT4 America's Am and Silver classes and a GT4-level production-based sports car in the GS class of IMSA Pilot Challenge. Her record also includes a season of solo open-wheel racing in US F4 and karting starts at SKUSA SuperNationals across the Pro Shifter, Pro X30 and X30 Senior classes.[1]
Her most substantial results have come in GT4 America, where two seasons with Heart of Racing produced a win and five podiums from twenty-two starts. Before that, she spent 2023 in US F4 with Crosslink/Kiwi Motorsport, finishing 18th in the championship standings after a full thirteen-round season. She has also carried six starts across eight years at SKUSA SuperNationals. Her current IMSA Pilot Challenge campaign with Heart of Racing is still in progress; she has taken back-to-back GS-class poles at Watkins Glen and Canadian Tire Motorsport Park in 2026, and shared a podium finish with Hannah Grisham after a third consecutive pole.[2]
Her most frequent opponent, Luca Mars, is a professional graded FIA Silver who has won championships in IMSA VP Racing SportsCar Challenge GSX and IMSA Pilot Challenge GS, and the two run closely matched. Against Tyler Gonzalez, an entry-level professional and 2023 TGRNA GR Cup North America Am champion with a heavy load of Pilot Challenge and GT4 America starts, she usually finishes behind. Her best scalps include Kenton Koch, an FIA Gold-graded established professional and champion in IMSA Prototype Challenge LMP3, GT World Challenge America Pro and GT4 America Silver, beaten three times, and Guilherme Salas, an established professional from Stock Car Pro Series, beaten twice.
