Following the conclusion of the 2025 NXT Gen Cup there was one additional race weekend held at Mantorp Park to crown the Swedish Junior Champion for the 2025 season. This marked the first race on Swedish soil for the series since its inaugural campaign, having shifted to a German-based calendar for 2024 onwards. Most of the field consisted of current or former NXT Gen Cup drivers, with a few drivers making their debuts in the cars.
Three races were held over the course of the weekend to determine the title winner, in what was billed as a grand finale for the main championship’s season. Experienced NXT Gen Cup competitor Alex Gustafsson claimed the crown, finishing second in all three races. Other notable entrants included 2023 NXT Gen Cup champion Elias Adestam - who took a race win and finished fourth overall - and TCR racer Viktor Andersson, who had a slightly underwhelming weekend.
