Nils Andersson began his motorsport career racing in Crosskart as a 13-year-old, with the Arvika native steadily progressing up the ladder in domestic competitions before winning consecutive RallyX Nordic CrossCar titles in 2018 and 2019.
Andersson then stepped up to the Supercar Lites category in 2020, helped by the support of sponsor Thorén I Kil, and reached the final on his series debut at Höljes.
A frustrating campaign followed but a switch to Kristoffersson Motorsport prior to the 2021 season saw a dramatic upturn in results, with Andersson emerging as a genuine title contender under the guidance of three-time FIA World Rallycross Champion Johan Kristoffersson.
A maiden podium in Round 3 at Höljes was followed by his first win in the series during the second leg of the double-header at the famous Värmland circuit, and another rostrum finish at OuluZone left him as the closest challenger to dominant points leader Tommi Hallman. Andersson went on to clinch the Swedish Championship during the RallyX Nordic season finale at Arvika.
