Valtteri Bottas led a Mercedes one-two in front of Lewis Hamilton to complete Friday's practice sessions ahead of this weekend's British Grand Prix.
Hamilton leads the world championship by 31 points from the Finn as he looks to win in Britain for a record sixth time this weekend, but he was pipped his team-mate to top spot at Silverstone by just 0.069 seconds following second practice.
The Silverstone track has been resurfaced ahead of the race and drivers struggled for grip in the session as the asphalt required cars to lay down rubber on the track through accumulated laps.

But no driver struggled more than Romain Grosjean who suffered the embarrassment of spinning out in the pitlane during the first session in the morning.
The Haas driver was making his way to start an outlap only to spin once he had passed the pitlane speed limit and negotiated what was otherwise a basic right turn.
After losing his front wing by crashing into a barrier, the Frenchman had no choice but to drive a short way back down the pits, where he could turn round and make a second attempt at joining the track.
A nip and tuck battle but it's Bottas who prevails in FP2 ??#BritishGP

Bits of his damaged front wing were littered onto the track as he made his way round before pitting to get his car fixed in a wasted run.
To make matters worse, once he did exit the garage he spun again on the circuit, perhaps showing a complete lack of confidence in his car as he ended the morning 19th fastest.
It sums up his worst season in F1 so far, where he has just two points - 12 less than team-mate Kevin Magnussen leaving him 17th in the championship.
But he was not the only one to suffer. The likes of George Russell, Lando Norris and Charles Leclerc were caught out by the lack of grip on the track with minor errors early on.
Although Mercedes later proved unbeatable in the afternoon, Ferrari have hopes of challenging the Silver Arrows this weekend with Leclerc less than two tenths off the pace of Bottas in third.
Team-mate Sebastian Vettel however was over four tenths down on the Monegasque driver in fourth, hinting that Mercedes were the team to beat this weekend following their curious under performance at the Austrian GP where Hamilton was fifth and Bottas third.
While Grosjean showed signs of feeling the pressure, another in Gasly ended the morning on a high with the fastest time. The Red Bull driver is in much need of a confidence boost after being lapped by team-mate Verstappen on his way to winning the Austrian Grand Prix last time out.
Gasly enjoyed the afternoon session too, recording the fifth best time three tenths quicker than Verstappen in seventh, who later claimed it was his 'worst Friday of the season.'
Splitting the Red Bull duo was rookie Lando Norris in the McLaren who will be looking to shine ahead of his home race.
His team-mate Carlos Sainz was eighth quickest, with Alex Albon and Sergio Perez rounding off the top 10.
Another Brit in George Russell was less fortunate with the struggling Williams team, ending the session slowest following gearbox troubles.
It proved to be an incident filled session in the morning, one that left Ferrari powered teams concerned when Kimi Raikkonen's power unit in his Alfa Romeo appeared to fail, bringing him to a stop out on track.
