On 8 March 2007 it was announced that Gommendy had been signed to drive for PKV Racing in the 2007 Champ Car season as a teammate to Neel Jani.
With Champ Car merging with IndyCar the following year, resulting in fewer available race seats, Gommendy joined Superleague Formula driving for F.C. Porto, winning a race at ACI Vallelunga Circuit in 2008 and Donington Park in 2009.
