Career
Like many aspiring motor racing drivers, Mustonen began his career with kart racing at the age of 11. The two back-to-back victories helped him to be named Finnish Karting Driver of the Year in 2003. The following year, 2004, was pivotal in Mustonen"s career, with him winning the Finnish Formula A Championship and being named Finnish Karting Driver of the Year once again.
He also competed in the Winter, Constructor and Pomposa International Cups, where he registered on the international radar for the sport.
The following year, he competed in the European version, where he registered a few podiums in another successful season. Mustonen was signed by Raikkonen Robertson Racing for the 2007 British Formula 3 Championship, as a teammate in the Championship class to Jonathan Kennard and Stephen Jelley.
He impressed with his fast but often erratic races, not uncommon for a young racing driver. He ended the year ranked 7th in the overall standings.
He returned for a second season in 2008, but had a largely uneventful season.
Mustonen moved to the Formula Three Euroseries for the 2009 season, driving for the Motopark Academy team alongside Christopher Zanella. Mustonen missed the rounds at Oschersleben due to health problems, and was replaced by Renger van der Zande. Mustonen returned for the rounds at the Nürburgring and Brands Hatch, before van der Zande returned to replace him from Barcelona onwards.
