British Grand Prix: Bottas pips Hamilton in second Friday practice
Valtteri Bottas stayed on top in second practice for Formula 1’s British Grand Prix, beating Mercedes team-mate Lewis Hamilton by only 0.047 seconds.
Bottas’s benchmark from the morning was beaten around 15 minutes into the afternoon session at Silverstone, as Hamilton posted a 1m28.780s on soft tyres before quickly improving to a 1m28.543s.
That put Hamilton a full six tenths clear of the field, led by Ferrari’s Kimi Raikkonen, until Bottas switched from mediums to super-softs at the 30-minute mark and set a new best of 1m28.496s.
When Hamilton took super-softs, he ran off the track at Chapel and told his engineers he feared he had damaged the car in the process. His soft-tyre time still kept him in second place.
With teams shifting their focus towards longer runs for the latter half of the session, Bottas’s best effort stood as the quickest time of the day.
Raikkonen was third-quickest, going 0.338s slower than compatriot Bottas on his super-soft run and 0.128 faster than the second Ferrari of Sebastian Vettel.
There was late drama for Raikkonen when he suffered a moment of snap oversteer at Becketts and span into the gravel, although he got going again without outside assistance.
Max Verstappen was best of the Red Bull drivers in fifth, 0.602s off the pace on super-softs, while team-mate Daniel Ricciardo was sixth, nearly half a second down on the sister car on the same tyre.
Nico Hulkenberg, Felipe Massa, Fernando Alonso and Esteban Ocon completed the top 10, all using super-softs, with Williams driver Massa spinning at Chapel late in the session after setting his best time.
Massa also attracted the attention of the stewards for impeding Verstappen, having passed the Red Bull driver around the outside at Club while both drivers were on long runs.
Carlos Sainz Jr had a major off-track excursion at the Maggotts/Becketts complex at the very start of the session, which consigned the Toro Rosso driver to the pits until the final 40 minutes.
He emerged to set the 11th quickest time, ahead of team-mate Daniil Kvyat in 12th.
Renault’s Jolyon Palmer also had a spin at Brooklands, ending up 18th ahead of only the two Saubers.

Bottas sets British GP practice pace as Vettel tries F1’s shield
Valtteri Bottas set the pace in opening practice for the British Grand Prix as Sebastian Vettel became the first Formula 1 driver to trial the shield cockpit protection device.
Bottas used the soft compound Pirelli tyres to clock a 1m29.106s at an overcast Silverstone, 0.078 seconds quicker than Mercedes team-mate Lewis Hamilton.
Championship leader Vettel, who was sixth fastest, headed out of the garage at the start of the session with the screen, which extends along the car’s nose in front of the driver, attached to his Ferrari.
He completed a single installation lap and then returned to the garage where Ferrari removed the device and switched attention to its weekend programme.
The medium compound – the hardest tyre available this weekend – was the rubber of choice for the early installation laps before Kimi Raikkonen fitted the super-softs and set the first time of the session with a 1m32.533s.
He traded quickest laps with the Red Bulls of Daniel Ricciardo and Max Verstappen, with Verstappen coming out on top initially.
Mercedes then sent Bottas out and he went quickest on the soft tyres with a 1m30.788s.
Hamilton lapped three tenths faster with his first real effort on the softs but his team-mate responded immediately to become the first driver to dip into the 1m29s.
Bottas continued to improve, gradually bringing his time down to a 1m29.106s, quicker than last year’s pole position time of 1m29.287s.
Red Bull emerged as Mercedes’ closest challenger, with Verstappen and Ricciardo third and fourth quickest respectively, but both their laps were set on the super-softs.
Raikkonen was the leading Ferrari in fifth, 1.031s off the pace but four tenths quicker than team-mate Vettel, who spun at Becketts and flatspotted his tyres.
Fernando Alonso, running the more-powerful ‘spec 3’ Honda engine in his McLaren again this weekend, was eighth quickest on the super-softs, a tenth behind Toro Rosso’s Daniil Kvyat.
Felipe Massa, whose Williams team adopted a split approach with its upgrades after a troubled Austrian GP by running different configurations on his and Lance Stroll’s cars, was ninth.
Stoffel Vandoorne made it two McLarens in the top 10, just half-a-tenth slower than team-mate Alonso.
Antonio Giovinazzi borrowed Kevin Magnussen’s Haas and set the 17th quickest time, nearly half-a-second off team-mate Romain Grosjean.
Jolyon Palmer missed much of the opening part of the session with his Renault up on stands in the garage, but the team eventually got him back out and he ended up 18th quickest after 16 laps.
