Jarno Trulli matched team mate Ralf Schumachers pace on Wednesday to keep Toyota at the top of the timesheets after a second day of testing at Silverstone. Trulli clocked a quickest lap of 1m 21.420s around the British circuit - just over one-tenth of a second better than Ferraris Kimi Raikkonen.
Though the forecast showers did finally arrive during the afternoon, Trulli covered 49 laps as he continued vital set-up work for Julys British Grand Prix. The Italian also worked through an engine evaluation.
The morning went pretty well for us testing set-up and tyres and I felt pretty comfortable with the car, explained Trulli. Then we changed the suspension settings so we lost some time around the lunch break. After the rain in the afternoon we only had about a half an hour more of meaningful work.
Raikkonen completed 62 laps as he concentrated on development of new mechanical and aerodynamic components on the F2007. With Felipe Massa expected on Thursday, it was the Finns first and final day at the Silverstone test.
Alexander Wurz finished third fastest for Williams. The team were testing a new aero package and tasked Wurz with evaluating its proficiency and working through a variety of set-ups to compliment it. The Austrian covered 45 laps and will now hand over testing duties to team mate Nico Rosberg.
Tuesdays second-fastest driver, McLaren tester Pedro de la Rosa, took up the fourth slot on Wednesday. De la Rosa completed 58 laps as he assessed aerodynamics, race set-up and tyres for the forthcoming British race. Fellow countryman Fernando Alonso will replace him on the final day.
Renaults Heikki Kovalainen finished fifth after evaluating new aerodynamic components in the R27. Although Kovalainen, who was delayed by the wet weather and an unscheduled engine change, managed just 53 laps, he remained positive about the French teams progress.
We have enjoyed two important days of testing, the Finn explained. We didn't do as many laps as we would have liked, but there were some very good tests even so. The car is more consistent to drive, and moving forward bit by bit. I think it's an encouraging sign for the next few races.
Vitantonio Liuzzi was the sixth-quickest driver for Toro Rosso. Despite interruptions, Liuzzi was one of the most productive runners of the day, covering 83 laps. With the STR2's new quick-shift gearbox continuing to work well and the aero optimization for the British race progressing positively, the team are hopeful they will finish their programme on Thursday, when Scott Speed takes over driving duties.
Liuzzis Red Bull stable-mate Mark Webber was seventh fastest. Webber continued to evaluate the team's new aerodynamic package but only covered 33 laps due to two engine-related problems. BMW Sauber test driver Timo Glock, meanwhile, finished in eighth as he completed tyre testing and began some suspension and aero development work.
Completing the days line-up was Adrian Sutil, ninth quickest for Spyker. Sutil carried out brake system evaluations, tyre work and set-up adjustments. Tester Giedo van der Garde and race driver Christijan Albers will share driving duties on Thursday during the third and final day of the test.
