Alberto Cerqui recorded the quickest lap time in free practice for the International Superstars Series at Donington Park.

The 18-year-old Team BMW Italia driver posted the fastest time of 1m34.334 during the first of the two sessions. He was 0.194s quicker than teammate and standings leader Thomas Biagi.

Max Pigoli was third quickest in his Romeo Ferraris Mercedes, 0.324s off Cerqui, with Friday test pacesetter Andrea Bertolini fourth in his Maserati Quattroporte just 0.027s behind. Johnny Herbert was fifth for Romeo Ferraris, three hundredths behind Bertolini.

Christian Montanari was sixth, with Luigi Ferrara a second off the pace in seventh. The Caal Racing Mercedes driver was still adjusting to the circuit having missed Friday’s test.

The second session was only ten minutes old when the circuit was hit by the English weather which brought heavy rain. Ferrara was quickest at that point, meaning he was on top when the session ended. His 1m39.272 was nearly five seconds off Cerqui’s time from the first session.

Biagi was second again, with Francesco Sini third in his Ferlito Motors Jaguar XF. Montanari was fourth, ahead of Stefano Gabellini and Riccardo Romagnoli.
