Canada practice notes: Friday

(GMM) Robert Kubica failed to set a lap time in the morning practice session in Montreal when he struck BMW engine trouble.

Williams' Nico Rosberg was the only other driver with even less fortune — he had to sit out the entire 90 minutes after handing over his car to test driver Kazuki Nakajima.

In front of already-bustling grandstands, McLaren's Fernando Alonso – despite a spin – and Lewis Hamilton led the pace, ahead of Kimi Raikkonen and Felipe Massa's Ferraris. Best of the rest was Mark Webber, for Red Bull.

Under-pressure Ralf Schumacher's decent pace for eighth quickest, meanwhile, was achieved with a set of so-called 'super-soft' Bridgestone tires.
