Formula Renault After an early career in
karting, Marsoin made his racing debut in 2005 in the
Formula Renault Campus France series, finishing the year in eighth position. The following year he moved up to the
French Formula Renault championship with the Epsilon Sport team, taking a single podium finish and fastest lap on his way to twelfth in the standings. He also took part in two races of the
Eurocup Formula Renault 2.0 championship. For
2007, Marsoin continued in French Formula Renault whilst also taking part in a full Eurocup Formula Renault season. Driving for
SG Formula in the French series, he took six podiums, including two race wins, to finish third in the championship, behind team-mate and champion
Jules Bianchi. In the Eurocup standings, he finished the year fourteenth overall.
Formula Renault 3.5 Series In late 2007, Marsoin took part in Formula Renault 3.5 Series testing at the
Circuit Paul Ricard and
Circuit de Valencia with the
Belgian KTR team, and in February 2008, he was signed by
Spanish team
Epsilon Euskadi to partner fellow rookie
Mario Romancini. During the
2008 season, Marsoin finished in the points on five occasions to end the year in nineteenth position, with his best race result being sixth-place finishes at both
Spa-Francorchamps and
Hungaroring. In the offseason, he tested for
Tech 1 Racing,
Prema Powerteam and
Comtec Racing before signing for the latter in January 2009. However, he did not appear at any of the pre-season tests or the first round in
Montmeló. He returned for the second round at Spa, but fell out with the team which led to him leaving the team during the weekend. He was replaced by
Max Chilton for the next round.
Formula Three Euroseries Marsoin replaced
Jon Lancaster for the opening round of the
2009 Formula Three Euroseries season at
Hockenheim. However, he left the team at
Lausitz. ==Racing Record==
