At the age of 19 in 2013, Huttunen decided to retire from go-kart competition and put a primary focus on rallying.
Despite middling results, Huttunen obtained enough funding to make his debut in the Finnish Rally Championship.
Still a member of the AKK Academy, Printsport hired Huttunen as a full-time driver in the 2015 Finnish championship in the R2 junior class, driving a Citroën C2 R2, like he did the previous season.
Huttunen opened the 2015 season with a podium finish at the Arctic Lapland Rally, his first long-distance event.
In the ERC however, he found himself regularly outpaced by Ingram, and with half the year by, he only took 2nd at the Canary Islands Rally.
Much to the surprise of many people, he won the WRC-2 class on his début in Finland, winning by 2 minutes and 17.8 seconds over Quentin Gilbert.
Huttunen ran the rest of his course with the Opel Junior Team, eventually finishing 3rd in the European Rally Championship-3 class.
Against stiff competition from the likes of Karl Kruuda, Gus Greensmith, Kalle Rovanperä and Pierre-Louis Loubet, Huttunen was chosen for the program.
Huttunen struggled in these rallies, failing to overcome the more competitive packages of Škoda Motorsport and Tommi Mäkinen Racing at Sweden, coming home 6th in the WRC-2 class.
In Mexico, Huttunen was forced out of both legs 1 and 2 early due to mechanical failures, and finished 6th once again, this time over an hour behind class winner Pontus Tidemand.
Huttunen was in the running for victory the entire rally, his closest opponent being Nikolay Gryazin in Sports Racing Technologies.
In his initial start for the 2019 season, he returned to Škoda customer team Printsport for Rally Sweden on a one-rally deal.
[12] He performed very strongly and even won the SS8 outright over the main WRC field, an unprecedented feat in R5 rallying.
