Jules Bianchi. Coletti felt that Bianchi had said "bad words" to him, and struck the
ART Grand Prix driver and championship leader. Coletti was then stripped of his third place, and was excluded from the rest of the meeting. He originally finished in eleventh place, but after
Marco Barba received a 25-second penalty, Coletti was promoted into the final points paying position in tenth. Coletti returned to the series for a full season in
2010, driving alongside

Dani Clos before taking this penalty. In his third GP2 race, at the
Circuit de Spa-Francorchamps, Coletti crashed heavily with two laps remaining causing the race to finish under
safety car conditions. He escaped with compressed vertebrae and minor bruising, missing the following day's sprint race as his car's
monocoque was written off by the impact. He also missed the
Brands Hatch rounds of the F3 Euroseries due to his injury. He was due to return to GP2 at
Monza having originally been passed fit, but pulled out due to recurring pain during Thursday scrutineering. Coletti returned to GP2 in 2011, driving for

main series strongly, winning the sprint race of the first round of the championship, held at
Istanbul Park. After winning the sprint race in
Hungary, he crashed heavily during the feature race at
Spa-Francorchamps and sustained two
vertebral compression fractures, two years after sustaining a similar, but more minor injury. He missed the rest of the season as a result. His seat was taken by compatriot
Stéphane Richelmi. in
2015. Coletti's injury healed, and he returned to GP2 for the
