🇩🇪 Stefan Aust

Stefan Aust is a professional-grade sportscar driver rated 4,572, placing him among the sharp end of competitive professionals. His FIA Bronze categorisation denotes an amateur or gentleman driver racing in endurance and GT competition, where he competes alongside full professionals graded Silver, Gold and Platinum. Across eight seasons from 2019 to 2026, Aust has made 13 starts in three series; his work has centred on the Nürburgring 24 Hours, where he has contested eight editions for Walkenhorst Motorsport without a podium finish. His average finishing position of P15.4 reflects the difficulty of breaking through in these competitive fields, yet his head-to-head record against front-running professionals tells a different story. Against multiple Platinum-graded rivals he has compiled a winning record: he has finished ahead of Raffaele Marciello (2023 GT World Challenge Europe champion and former FIA Formula 3 European champion) in five of five shared races, ahead of Antonio Fuoco (also Platinum) in all five encounters, and ahead of Lucas Auer (2024 GT World Challenge Europe champion, also Platinum) in four of six races. He has also beaten Thomas Preining, the 2023 DTM champion, and Laurin Heinrich, the 2024 IMSA WeatherTech GTDPRO champion, multiple times.[1]

Aust's record against Klaus Bachler, the 2024 WEC LMGT3 champion and a Platinum professional, stands at five wins to two losses across seven shared races, underlining his ability to compete at the level of established champions despite his own amateur status. His 2026 activity has extended to the Asian Le Mans Series with Proton Competition, a team that has fielded strong drivers and accumulated 19 wins across its index record. While Aust has not yet recorded a podium finish in the major endurance races where he competes, his consistent performances against world-class professionals of higher grades suggest a driver capable of running with the established elite of his chosen discipline.[2]
