🏳️ William Peluchiwski

William Peluchiwski races in national semi-professional sportscar championships. His primary campaign is in the Porsche Sprint Challenge North America Cayman class for Kellymoss, where he drives the Cayman in solo sprint racing across multiple venues in the United States. He has also competed in the Lamborghini Super Trofeo NA LB Cup class and the Porsche Endurance Challenge North America, the latter a multiclass endurance series in which his car is shared among drivers.[1]

Across three seasons from 2021 to the present, Peluchiwski has taken six wins and thirteen podiums from nineteen starts. His breakthrough came in 2025, when he won three races and took nine podiums across the Porsche Sprint Challenge season. That form has carried into 2026; he currently sits third in the Porsche Sprint Challenge championship standings after ten rounds, with two wins and seven podiums so far. In the Porsche Endurance Challenge this year he has taken both available starts as victories. His early success in Lamborghini Super Trofeo in 2021 included one win and two podiums across four races.[2]

Peluchiwski operates in a field of club-level racers and semi-professionals. He regularly races against Greg Cecchi, a club-rated driver he remains closely matched with, and typically finishes ahead of Tom Kerr, another club competitor with substantial experience across multiple Porsche and Lamborghini series. He has beaten Mark Kvamme and Terry Olson, both entry-level professionals who won the 2021 Lamborghini Super Trofeo LB Cup championship, twice each; Kvamme has since raced in IMSA's top prototype and GT categories, while Olson has started in IMSA Prototype Challenge and NASA competition. Kellymoss, the established team fielding his car, has won 66 races across the index with a roster that includes established professional drivers.
