Christian Klien made it a double victory for former Formula 1 drivers in the International Superstars Series round at the Hungaroring – even though he went into the final lap in fourth place.

Colombian Camilo Zurcher had crossed the line first to record his first win in just his second weekend in the series, but the Romeo Ferraris Mercedes driver was subsequently penalised 30 seconds for contact with polesitter Domenico Ferlito's Jaguar on the opening lap of the race.

That handed victory to Klien, who was making his Superstars debut this weekend in the #1 Swiss Team Maserati Quattroporte. The Austrian had already inherited two places on the last lap after Thomas Biagi spun race one winner Vitantonio Liuzzi around in their battle for second.

They crossed the line third and fourth respectively, before the stewards penalised Biagi eight seconds in order to reverse their positions. After Zurcher's penalty, Liuzzi then inherited second place behind Klien, the man he shared a Red Bull drive with back in 2005.

Franco Fumi took fourth on his debut weekend with the same Dinamic BMW team that Biagi drives for, ahead of the team's other driver Stefano Gabellini.

Zurcher ended up sixth after his penalty, ahead of Paolo Meloni's privateer BMW and the Chevrolet Lumina of Francesco Sini. Zurcher's teammate Andrea Larini was ninth, while Thomas Schoffler was classified tenth in his Audi despite stopping four laps from home.

The other two RS5s also failed to finish, with points leader Johan Kristoffersson stopping on the formation lap and Gianni Morbidelli suffering yet another technical retirement, this time while running second. Local hero Norbert Michelisz saw his one-off appearance come to an end on lap five.
