Mercedes driver edges team-mate Hamilton as German GP gets underway at Hockenheim.
Nico Rosberg topped the timesheet in the opening practice session of the German Grand Prix weekend, the German beating Mercedes team-mate Lewis Hamilton by just 0.065s.
Rosberg’s time of 1:19.131 beat his title rival team-mate's best lap by six hundredths of a second as Hamilton frequently aborted quick laps as he worked through his morning programme.
Behind the Mercedes pair, Fernando Alonso was third-fastest for Ferrari, the Spaniard finishing just under three tenths of a second adrift of Hamilton.
Fourth place went to Red Bull Racing’s Daniel Ricciardo who was over half a second down on Rosberg's time. Jenson Button was fifth, with team-mate Kevin Magnussen seventh as McLaren continued the good form they showed in Silverstone a fortnight ago.
Splitting the McLarens was Sebastian Vettel in the second Red Bull. The 2013 German Grand Prix winner finished the opening session four tenths of a second behind his team-mate and almost a full second behind compatriot Rosberg.
With Magnussen in seventh, eighth place went to Kimi Raikkonen, back at the wheel of his Ferrari after he was forced to sit out last week’s Silverstone test in the wake of a heavy accident at the British Grand Prix. The final two top-10 places went to Toro Rosso’s Daniil Kvyat and Sauber’s Adrian Sutil.
Elsewhere, Williams development driver Susie Wolff made a second and far more successful FP1 appearance for the Grove team.
At Silverstone the Scot’s grand prix weekend debut lasted just four laps before an oil pressure problem sidelined her and early on at Hockenheim it seemed as if she was destined for more heartbreak as an issue on her installation lap forced her back to the pits.
The problem was rectified, however, and she was able to complete a total of 22 laps, with a best time of 1:20.76. That left her in P15, just 0.227s off the best time set by team-mate Felipe Massa.
