 After returning the German F3 in 2002, and finishing fifth overall, van Hooydonk was again promoted to F3000 and remained there for the 2003 and 2004 seasons, with moderate success.This was not enough to get him a drive in the new GP2 Series which replaced F3000 in 2005, and, despite a test with the MF1 Formula One team, he returned to tin-top racing by competing in the European Mégane Trophy for that year, finishing the championship in fourth whilst driving for ex-F1 driver Thierry Boutsen's team.Van Hooydonk has also competed in some endurance races at Zolder, Spa-Francorchamps and Le Mans.
