Spanish Grand Prix:Formula One's practice king this season again ruled the roost ahead of Sunday's Spanish showpiece as for the eighth time in 14 sessions this year, it was Williams' Nico Rosberg who topped the timesheets.
Come the end of the second 90-minute session at Barcelona’s Circuit de Catalunya, the 23-year-old had set the fastest time of the day overall with a lap of one minute 21.588secs.
But Rosberg did not have it all his own way because just minutes prior to the session coming to a close, he was forced to trundle off the track and park his car on the grass due to an apparent electrical problem.
Despite that issue, it proved to be a productive day for Williams as Kazuki Nakajima was second quickest, just 0.152secs adrift of his team-mate.
Williams’ concern this season, though, is they have yet to transfer their practice pace into a decent qualifying performance or race result.
Rosberg has managed just 3.5 points so far, with his best finish a sixth in the season-opening Australian Grand Prix, whilst Nakajima has yet to get off the mark.
If they can finally deliver on the promise they present, then they could still come into the championship reckoning.
Behind the Williams’ duo it was Fernando Alonso in his Renault as he gave his fans something to cheer, followed by Rubens Barrichello for Brawn GP and Red Bull Racing’s Mark Webber.
Championship leader Jenson Button, quickest in first practice with a time that proved to be the third best of the day, was sixth in the second session, narrowly ahead of one of his main title rivals in Red Bull’s Sebastian Vettel.
As for the big guns, Kimi Raikkonen headed that particular list, but hardly something to be proud of as he was tenth for Ferrari.
Current world champion Lewis Hamilton was down in 13th in a McLaren he rightly predicted would not be competitive on this track, with team-mate Heikki Kovalainen 14th, and Felipe Massa a place further back in his Ferrari.
After finishing second, third and fourth in first practice, Jarno Trulli of Toyota and the BMW Saubers of Robert Kubica and Nick Heidfeld, were 19th, 16th and 17th in the afternoon.
Clearly experimenting with different set-ups and heavier fuel loads, their times later in the day were all a second off those posted in the morning.
Adrian Sutil was again last, albeit without setting a time as a fuel cell problem in his Force India that materialised in first practice, forced him to sit out the entire second session.
