Mercedes driver Nico Rosberg continued to set the pace during the second practice session for this weekend’s British Grand Prix at Silverstone.
Rosberg, who was victorious at the circuit in 2013, posted a time of 1:34.155 to end the session 0.347s clear of Ferrari rival Kimi Räikkönen.
Sebastian Vettel was third while Lewis Hamilton finished in fourth place to ensure that the leading Mercedes and Ferrari quartet was covered by less than half a second.
Daniil Kvyat was fifth for Red Bull, ahead of team-mate Daniel Ricciardo, as the squad ensured it remained within a second of Rosberg’s leading time.
Toro Rosso slipped back compared to its first practice pace but still had an encouraging session as Max Verstappen was seventh and Carlos Sainz Jr. took ninth, with the pair split by Force India’s Nico Hülkenberg.
Felipe Massa survived a couple of lurid moments early on in the session to round out the top 10 for Williams.
Pastor Maldonado finished in 11th place, ahead of Valtteri Bottas and Sergio Pérez.
Romain Grosjean caused a red flag early in the session after he went into the gravel at Luffield and got stuck; the Frenchman informed his Lotus squad that the rear end of the car felt unusually unstable.
Grosjean's car was returned to the garage where he assisted the mechanics in removing the dust from the E23 Hybrid before heading back out on circuit.
Fernando Alonso was 15th in the wayward McLaren via making a similar error to Grosjean.
Unlike Grosjean, Alonso was able to work his way through the gravel and make it back onto the circuit.
Sauber took 16th and 18th with Felipe Nasr and Marcus Ericsson, who returned to the cockpit of the C34 after handing over to Raffaele Marciello in the first session.
Jenson Button split the Sauber drivers but spent a large portion of the session in the garage after complaining about the feel of the MP4-30.
Will Stevens was 19th fastest, a second behind Ericsson, and he ended 1.5 seconds ahead of Manor Marussia team-mate Roberto Merhi.
The Spaniard suffered a spin at Luffield and caused the session to be red flagged, though he was able to re-join the track and return to the pits.
