Toyota’s Jarno Trulli endured a woeful opening day of practice for the 2008 British grand prix.
The Italian, despite finishing on the podium two weeks ago at Magny-Cours, looked slow at Silverstone, and then crashed at Stowe corner when his rear wing fell off.
Toyota’s misery was compounded by a gearbox problem for teammate Timo Glock.
Toyota-powered Williams racer Kazuki Nakajima also crashed during the second 90-minute practice session, after losing control on the approach to Bridge corner.
At the very top of the times, McLaren’s Heikki Kovalainen set the pace throughout the afternoon; half a second quicker than home hero Lewis Hamilton, who was beaten to second spot by Mark Webber’s Red Bull.
Felipe Massa sat much of the session out following his morning crash, ultimately doing 18 laps for the eighth quickest time. His Ferrari teammate Kimi Raikkonen was just 12th.
