Bruno Senna, R31-01 P17, 1:53.835, 21 laps
Vitaly Petrov, R31-05 P24, 2:02.234, 12 laps
Bruno Senna emerged as the faster Lotus Renault GP race driver after ongoing variable weather conditions at the Spa Francorchamps circuit during the second practice session for the Belgian Grand Prix.
Bruno enjoyed a trouble-free run to set a 1min 53.835secs lap whilst Vitaly Petrov had his session curtailed as the team investigated an issue with the power steering system on his R31.
Bruno ended the day with the 17th fastest time of the session, despite being baulked when the circuit was drying; Vitaly missed out on setting a lap time on dry tyres due to his steering investigation, and ended the session with the 24th fastest time, set on intermediate tyres.
Both drivers used the soft slick Pirelli and the intermediate tyres, Bruno also used the wet tyre during the course of the 90 minutes.
On the eve of his 35th birthday, Mark Webber set the fastest lap time of the session, a 1min 50.321secs, ahead of Fernando Alonso and Jenson Button.
