Filippi drove for the ART Grand Prix team in the first half of the 2008 GP2 Series season, alongside Romain Grosjean. Following a disappointing first half of the season, Luca left the team in favour of Sakon Yamamoto after ten races. Filippi was confirmed as a driver at the Arden International team two days later, where he replaced Yelmer Buurman. His results failed to improve and he finished nineteenth in the championship.
