Karting
Born in Våler, Norway, Olsen began karting in his native Norway, aged six.[1][2] After winning numerous junior titles, he stepped up to the KF3 class in 2009, winning the Norwegian title. He retained his title in 2010, a year which also saw him finish second in the Junior Monaco Kart Cup and third in the German Junior Karting Championship. In 2011, Olsen won his third consecutive Norwegian KF3 title, the German KF3 championship and the WSK Cup Final KF2 titles. For his final year of karting in 2012, he successfully defended his WSK Cup Final KF2 title and also won the prestigious German KF1 karting championship.[3]
Toyota Racing Series
Olsen began his single-seater career in early 2013, racing in the New Zealand-based Toyota Racing Series, becoming the first Norwegian driver to enter the series. He finished the championship in thirteenth place, scoring a best race result of fifth in the final round of the series at Manfeild.[4]
For 2014, Olsen graduated to the Eurocup Formula Renault 2.0 championship with Prema Powerteam.[8] He finished second in the standings, behind champion Nyck de Vries, after taking three podium places including race wins at Spa-Francorchamps[9] and the Nürburgring.[10] At the final round of the season in Jerez, he finished second in the first race, a result that initially earned him the runner-up spot in the championship, but was later disqualified for a technical infringement.[11] He did, however, secure second in the championship the following day after finishing seventh in the final race of the season.[12]
He also contested a partial campaign in the Formula Renault 2.0 Alps championship with Prema, taking six top ten finishes in the six races he took part in.
Olsen remained in Eurocup Formula Renault 2.0 for a second season in 2015, switching to ManorMP Motorsport.[13]
For 2024, Olsen would switch to become a Ford factory driver, competing with the new Ford Mustang GT3 for Proton Competition alongside Mikkel O. Pedersen and bronze-ranked Giorgio Roda.[16] Following a slow start in the first three rounds, Olsen led the team towards its first podium of the season, finishing third at the 24 Hours of Le Mans.[17][18]
