Career

Born in Saint-Brieuc, near Côtes d'Armor, Boullion started karting in 1982 and moved to cars in 1988 after attending a racing school outside Paris. He started racing in Formula Ford 1600 in 1989. The following year he won the French title and moved to Formula 3. In 1993 he entered Formula 3000 and won the FIA International Championship in 1994. Although he was signed to test for Williams, he was loaned to Sauber to replace Karl Wendlinger for much of the 1995 season, scoring points twice but rarely matching his team-mate Heinz-Harald Frentzen. The following year he returned to his testing role at Williams, and he later tested for Jordan and Tyrrell.

In 1997 he raced briefly in the Renault Spider Eurocup, and he campaigned a Renault Laguna touring car for the Williams team in the British Touring Car Championship (BTCC) in 1999, acquiring the nickname 'JCB' from commentator Charlie Cox. In 2000 he turned to sports car racing with some success, and has raced several times in the 24 Hours of Le Mans. He earned a third place in the 2007 24 Hours of Le Mans, along with Emmanuel Collard and Romain Dumas a Pescarolo Sport entry.

After a stint with Rebellion Racing, he returned to Pescarolo Team for 2012, driving in the FIA World Endurance Championship.
