Hilmer Wiberg (born 2005) is a Swedish powerboat racer who has achieved multiple world championships across different racing categories. He is best known for winning the 2022 GT30 World Championship and being the runner-up in the 2025 UIM F2 World Championship, where he finished second to his sister Mathilda Wiberg in a dramatic season finale.[1] Wiberg is a prominent member of the Swedish powerboat racing scene and represents the Wiberg Racing team alongside his sister.
Wiberg comes from a powerboat racing family based in Åkersberga, Sweden, located about 40 km north of Stockholm. His father introduced both Hilmer and his sister Mathilda to the sport, and the entire Wiberg family travels to races together as a team under the banner of Wiberg Racing.[2]
Hilmer began his powerboat racing career in the mid-2010s, competing alongside his younger sister Mathilda in various junior categories before progressing to senior-level competition.
Racing career
Junior championships (2016-2020)
Wiberg's breakthrough year came in 2019 when he achieved multiple championship successes. He won the GT15 European Championship, demonstrating his skill in the junior category where drivers compete until age 16.[3] The same year, he earned a silver medal in the UIM Class 3J World Championship, partnering with William Sjöström while his sister Mathilda and Stefan Arand won the gold.[4]
The racing media noted that this gave "the family another medal" and highlighted the competitive nature of the Wiberg siblings even in their early careers.[4]
GT30 dominance (2020-2022)
After aging out of GT15, Wiberg moved to the GT30 category where he achieved considerable success. In 2022, he dominated the GT30 World Championship, with racing media reporting that "Hilmer Wiberg from Sweden won the GT 30 Worldchampionship" ahead of Laura Lakovica from Latvia in second place and Kärol Soodla from Estonia in third.[5]
His dominance in GT30 was also evident in other competitions, with reports of him taking "all three heat victories in GT30" at various race meetings.[6]
Formula 2 career (2025)
Wiberg's transition to the premier UIM F2 World Championship category marked the next phase of his career, where he would ultimately compete directly against his sister Mathilda for world championship honours.
2025 season
In 2025, Wiberg achieved a bronze medal in the F2 European Championship in his rookie season, finishing third behind Nikita Lijcs and Edgaras Riabko.[7].
Throughout the World Championship, he secured multiple podium finishes, including a third-place finish in the season opener at Brindisi, Italy, where he finished behind winner Matthew Palfreyman and runner-up Peter Morin.[8]
Going into the championship-deciding final race in Vila Velha de Ródão, Portugal, Wiberg held the championship lead with 39 points, ahead of his sister Mathilda (34 points) and Peter Morin (32 points).[9]
The dramatic finale
The championship-deciding race on 21 September 2025 proved to be one of the most dramatic in F2 history. Starting from fifth position on the grid, Wiberg was in contention for the title when disaster struck.[1] On lap 25, "championship leader Hilmer Wiberg's title challenge unravelled when technical gremlins forced his retirement, ending his hopes."[1]
The mechanical failure eliminated Wiberg from the race at the crucial moment, allowing his sister Mathilda to take control and ultimately claim both the race victory and the world championship.[1] Despite the disappointment of losing the title, Hilmer was classified as the championship runner-up, finishing second in the final standings.[10]
