SILVERSTONE -- Lewis Hamilton topped final practice for the British Grand Prix before drizzle in the final 20 minutes of the session made conditions too treacherous for slick tyres.
The top three drivers were split by 0.074s, with Sebastian Vettel just 0.032s off his title rival Hamilton and 0.042s ahead of the second Mercedes of Valtteri Bottas. The quick times were all set on super-soft tyres before a band of light rain swept across the circuit and put an end to meaningful qualifying simulation runs.
All drivers returned to the track on intermediate tyres in the final five minutes, but only managed a handful of laps to gauge grip levels before completing a practice start at the end of the session.
