In 2026, Martin is competing in GB3 (former British F3) with Rodin Motorsport, the reigning 2025 championship-winning team. During the season, the series visits iconic circuits such as Silverstone, Spa-Francorchamps, and the Hungaroring. In the official pre-season tests, the 17-year-old Hungarian driver set the fastest-ever GB3 lap at both Donington and Brands Hatch.
