Bruno Senna (Arden International) and Timo Glock (iSport International) have both taken wins on Bridgestone Potenza slick tyres at Circuit de Catalunya this weekend. Senna took his first GP2 Series race win and Glock had his first victory of the season.
Saturday's 39 lap race was won by Senna after starting from sixth on the grid. Glock finished over five seconds behind Senna taking second place after starting in pole position, while Lucas Di Grassi (ART Grand Prix) finished third for a place on the podium. Saturday's race was eventful as five drivers had retired by Turn 2 and the safety car was out on the first lap.
Sunday's 26 lap race was won by Timo Glock who started in seventh due to the reverse grid for the top eight finishers from race one. Glock finished over eight seconds ahead of Javier Villa (Racing Engineering), and Di Grassi took another third place finish.
Glock now leads the Drivers' Championship with 31 points followed by Senna on 18. The third round of the GP2 Series takes place at Monte Carlo, alongside the Monaco Grand Prix 24-26 May with just one race scheduled for the weekend (Saturday 25 May).
Hirohide Hamashima, Director of Bridgestone Motorsport Tyre Development said: "I think the Bridgestone Potenza tyres worked well this weekend. The majority of drivers commented that after the safety car in race one the tyres warmed up within one lap. Due to an incident and the safety car being deployed at the beginning of the race most drivers changed their tyres on the second lap. After 15-20 laps the car balance was going to oversteer but many drivers said it was controllable. At the end of the race, a few drivers found the cars hard to control as they had run most of the race on the same set of tyres from lap two. The drivers competed hard today (Sunday) and the race itself was spectacular. In terms of lap time the tyres worked very well. Bridgestone is very happy to support the young drivers in the GP2 Series."
