Mads Siljehaug is a Norwegian racing driver currently competing in GT World Challenge America with Chicago Performance and Tuning Co. Prior to this stage of his career, he spent time with Reiter Engineering, where he built a background in GT4 and LMP3 machinery. Among his notable achievements are the 2019 ADAC GT4 Germany championship and a runner-up finish in the 2022 Le Mans Cup, both of which mark him as an experienced hand across GT and prototype categories in Europe before his move to North American competition.[1]

In GT World Challenge America, Siljehaug remains without a championship, race win, or podium finish through two career starts. His 2026 season has begun with a single round completed, no wins or podiums, and a tenth-place position in the standings. His Racer Rating stands at 2,412, placing him 4,467th among active drivers on the platform's Elo-style scale. As an active competitor still building his results in this series, Siljehaug's American campaign remains in its early stages, with his prior European success suggesting room for growth as he continues to gain experience with Chicago Performance and Tuning Co.[2]
