Kimi Raikkonen [ Images ] put a revived McLaren [ Images ] back on top of the timesheets in practice for the team's home British Grand Prix [ Images ].

The young Finn, overall runner-up last year but little more than an also-ran in an uncompetitive car for the first half of this season, lapped in one minute 18.655 seconds on Friday, a mere 0.005 of a second quicker than Sauber's Italian Giancarlo Fisichella [ Images ].

Fisichella's day was bittersweet, his car finding its pace only after the engine was changed in the morning -- a move imposing a 10 place penalty on the starting grid after Saturday's qualifying.

Ferrari's [ Images ] world champion Michael Schumacher [ Images ], dominant winner of nine of the season's 10 races and seeking his 80th career victory on Sunday, was third fastest.

Raikkonen's British team mate David Coulthard [ Images ], twice a winner at Silverstone, was fourth while compatriot and home favourite Jenson Button [ Images ] in a BAR was fifth.

Ferrari's Rubens Barrichello [ Images ] had earlier fired up his challenge for a second successive win in Britain with the fastest time in the day's first practice.

The Brazilian, without a victory so far this season, won from pole position with a lap record time in 2003 and is eager to repeat the feat after finishing runner-up six times in the last 10 races.

Williams looked strong in the first session, with Colombian Juan Pablo Montoya [ Images ] third and Spanish stand-in Marc Gene fourth quickest in his second race in a row as a replacement for injured Ralf Schumacher.

Germany's [ Images ] Timo Glock [ Images ] crashed with eight minutes remaining in the second session when his Jordan lost a rear wheel. The test driver emerged from the car unscathed.
