British GP: Nico Rosberg leads practice, Lewis Hamilton only fourth
Nico Rosberg set the pace again in Friday afternoon British Grand Prix practice at Silverstone, with his Mercedes Formula 1 team-mate Lewis Hamilton only fourth behind the Ferraris.
Rosberg, quickest in first practice, clocked a 1m34.155s on the medium compound tyres to finish 0.466 seconds and three places clear of Hamilton, who made a mistake in the final sector on his low-fuel run.
Ferrari’s Kimi Raikkonen, who has endured torrid weekends at the last two races in Canada and Austria, was second quickest, 0.02s clear of team-mate Sebastian Vettel.
It was a frustrating day for Hamilton, who was unhappy with the stability of his Mercedes and reported during his long run that "the car is all over the place", although he had been quickest on the hard tyres at first.
The session, held in beautifully sunny conditions with air temperatures hovering around 23C, was red-flagged early on when Romain Grosjean beached his Lotus at Luffield.
On the resumption, Red Bull’s Daniil Kvyat popped up into second on the hard tyres. Though he was unable to improve on mediums, that time still kept him fifth until the end, a tenth clear of team-mate Daniel Ricciardo.
Toro Rosso’s strong day continued as Max Verstappen finished seventh and Carlos Sainz Jr ninth with Nico Hulkenberg splitting the duo in eighth in the revised Force India after an early spell in third behind the Mercedes.
Felipe Massa was the highest-placed Williams, which does not traditionally show its true pace on Fridays, in 10th with Valtteri Bottas, who missed first practice as Susie Wolff was in the car, 12th.
Pastor Maldonado was 11th, two seconds off the pace, with Grosjean rejoining the fray after his earlier off to end the session 14th, one place behind Force India’s Sergio Perez.
McLaren continued its plan to limit its running, after both Fernando Alonso and Jenson Button changed engines to older units, with Alonso 15th and Button 17th and just 34 laps between them. Alonso had a minor excursion at Luffield but avoided getting stuck.
Sauber expected the sweeping turns of Silverstone to prove challenging for its car and so it proved with Felipe Nasr 16th and Marcus Ericsson 18th.
Roberto Merhi brought out a second red flag when he spun at Luffield, beaching the Manor in the gravel.
But he was able to get going again when marshals pushed him back onto the track.
The Spaniard propped up the timesheets, 5.7s off the pace and 1.6s slower than his team-mate Will Stevens in 19th.

British GP: Nico Rosberg recovers from problem to top practice
Nico Rosberg recovered from an early hydraulic problem to top the first free practice session for Formula 1’s British Grand Prix with a series of late fast laps.
The German was ordered to stop the car with a loss of hydraulic pressure on his sixth lap of the day shortly after the 15-minute mark, having just set the fastest first-sector time seen to that point.
While Rosberg was recovered to the pits, the way seemed clear for Lewis Hamilton to top the 90-minute session.
He was fastest during the first 30 minutes, when everyone was on their first set of hard-compound Pirellis, improving by just under eight tenths on his second run.
That looked to be enough to guarantee top spot, only for Rosberg to hit the track late on after time in the pits ensuring his car was operational.
By that time, Rosberg had slipped to seventh, but on his first serious flier he jumped to second before banging in two laps quicker than Hamilton’s best – the first one hundredth faster, the second seven hundredths quicker.
Having expected to go well on the high-speed track thanks to the strength of the chassis, Toro Rosso drivers Max Verstappen and Carlos Sainz Jr backed up their claims by showing strong pace in third and fifth places respectively.
They were down in seventh and eighth after the first runs, but both set their best times on the second set of tyres early in the final hour.
It seemed they would end the session third and fourth only for Ferrari driver Kimi Raikkonen, who lost time on his second set of tyres with an MGU-H problem, to improve his pace late on and split the pair.
Sebastian Vettel was not able to match his team-mate’s raw speed, ending up in sixth place.
Red Bull’s lead driver, Daniel Ricciardo, was 1.5s off the pace but not far behind Ferrari in seventh place, with team-mate Daniil Kvyat barely slower.
Nico Hulkenberg, in the much-vaunted B-spec Force India, was ninth fastest ahead of Williams driver Felipe Massa.
Several non-race drivers ran during the session, with Susie Wolff the best-placed in 13th overall for Williams, just under eight tenths off Massa.
Lotus reserve Jolyon Palmer was just two hundredths behind, with Sauber’s Raffaele Marciello 15th.
McLaren endured a troubled session. Fernando Alonso and Jenson Button completed only 22 laps between them and outpaced only the two Manor entries of Will Stevens and Roberto Merhi.
Button lost time with a leak, while Alonso trialled an experimental suspension configuration that then had to be changed once the team had gathered data on it.
