Jenson Button set the pace in the first free practice session for the German Grand Prix at Hockenheim as McLaren used its updated MP4-27 on track for the first time. The Briton's 1m16.595s lap was 0.498s faster than his team-mate Lewis Hamilton, with championship leader Fernando Alonso third on the timesheets for Ferrari. Intermittent rain showers rendered times fairly irrelevant in terms of determining form, with teams frequently having to cut short evaluation runs for the updates they have brought to Germany.
