Australian
Patrick "Pat" Heuzenroeder (born 17 November 2005) is an Australian racing driver who lived out a fairytale at the 2026 Australian Grand Prix, making a last-minute FIA Formula 3 debut on home soil with Campos Racing.
The climb
Heuzenroeder's route into motorsport was late and unconventional. He didn't catch the racing bug until he was 13, during a family visit to Sydney's Eastern Creek go-kart circuit, and spent the next three years karting, including an outing in the 2022 Australian Kart Championship. Rather than serve the long, expensive European karting apprenticeship most of his rivals went through, he jumped almost straight into cars, contesting seven races of the 2022 Formula Ford Australian Championship before setting his sights on the European single-seater ladder.
GB3 breakthrough
The defining chapter of his junior career came in British F3 (GB3). He first joined JHR Developments, then switched to Xcel Motorsport for 2025 and delivered the season that put him firmly on the radar of European team bosses: he finished the year as GB3 vice-champion, with a race win, multiple podiums and a long run of top-five finishes against a deep and competitive field. That runner-up campaign marked him out as one of Australia's most promising open-wheel exports and, by his own account, drew interest from several leading teams across the European championships.
2026 / temporada actual
For 2026 Heuzenroeder committed to Campos Racing, the Spanish squad with whom he had already finished fourth in Eurocup-3 in 2025; a full Eurocup-3 title bid is his primary programme. His FIA Formula 3 break, however, arrived by chance rather than design. Campos regular Ernesto Rivera suffered a vertebral injury racing in Formula Regional Oceania over the off-season and was ruled out of the season-opening round in Melbourne. Heuzenroeder, who had already deputised for Rivera during pre-season testing, was drafted in at short notice, handing him an F3 debut at his home Australian Grand Prix at Albert Park, racing for reigning F3 teams' champions Campos in front of a partisan crowd. It was a dream stage for a young Australian on the Formula 1 support bill, even if his confirmed F3 mileage so far remains limited to that one-off stand-in role. With a Eurocup-3 title push and an early taste of F3 behind him, he is firmly part of the long-term conversation as a potential championship regular.
