Lewis Hamilton edged out teammate Nico Rosberg as Mercedes took command of the first German Grand Prix practice session.
The Briton finished more than one second clear of the entire field bar Rosberg, with whom he traded fastest laps as the squad hit the front at the halfway stage. Hamilton eventually settled the fight with a 1m31.754s which put him two tenths clear of Rosberg, victorious last time out at Silverstone.
Red Bull’s Mark Webber prevailed in what was a much tighter fight for third, eclipsing the lead Force India of Adrian Sutil by just 0.033sec.
Kimi Raikkonen, Felipe Massa and Jenson Button all got within four tenths of Webber’s time. Despite Massa’s pace it was an unhappy session for Ferrari, however, as Fernando Alonso failed to complete a lap due to electrical issues.
The Spaniard lost power and abandoned his car just four minutes into the session, and then suffered an almost identical failure 40 minutes later on what was his second attempt at a first installation lap. This time he was at least able to revive the car and return to the pits, but was unable to return and ended the session with just two aborted laps under his belt.
Sebastian Vettel, Alonso’s chief championship rival, ended the session in eighth ahead of Romain Grosjean, who slipped in front of Sergio Perez and Paul di Resta as the checkered flag fell.
