Team BMW Italia repeated their result from the first International Superstars Series race at Portimao in Race 2, as Thomas Biagi won again with Alberto Cerqui and Stefano Gabellini second and third once again to complete another 1-2-3 for the team.

Cerqui started on pole again, but this time the youngster lost the lead to Andrea Bertolini in the Swiss Team Maserati on the opening lap, before losing second to teammate Biagi on lap two. Biagi chased down Bertolini and soon took the lead from the Maserati driver.

Just like in Race 1 Bertolini suffered a tyre problem, this time forcing him out of the race. This left Biagi to win with Cerqui not far behind him. Luigi Ferrara held third in his Caal Racing Mercedes but would eventually be passed by Gabellini to allow the BMW man to complete a double podium lockout for his team.

Max Pigoli (Romeo Ferraris) got past Ferrara on the penultimate lap to finish fourth. Andrea Chiesa finished sixth in his Maserati, with Ferrara's teammate Riccardo Romagnoli seventh. Andrea Dromedari was eighth in his Romeo Ferraris Mercedes ahead of Mauro Cesari in the MRT by Nocentini Chrysler 300C and Sandro Bettini in his Movisport BMW.

Johnny Herbert had been fighting with Gabellini for fifth early on until suffering another puncture, just as he did in Race 1.

Biagi's double win has moved him to the top of the standings, nine points ahead of Ferrara with Pigoli a further ten points behind. The next Superstars race takes place at Misano on 5th June, counting for the Italian championship only. The next International Superstars Series round is at Donington Park on 19th June.
