Hamilton leads Mercedes lock-out in Spain

The Mercedes driver posted a 1:25.232 to beat team-mate Nico Rosberg, who had topped final practice, by 0.168 seconds. Third-placed Daniel Ricciardo was more than a second down on the top spot, while reigning World Champion Sebastian Vettel stopped out on track in Q3.

Heading into the final shootout, it was Rosberg who held the upper hand, the German topping both Q1 and Q2 as Hamilton struggled to get to grips with his tweaked car.

But on the final Q3 runs, Hamilton put his lap together perfectly to surge clear and deny Rosberg pole.

Ominously for the remainder of the field, 1.053 seconds separated Hamilton and the Red Bull of Ricciardo, suggesting that tomorrow's race will be no more than a battle between the two Silver Arrows machines.

Valtteri Bottas took an impressive fourth for Williams, ahead of Lotus's Romain Grosjean and the Ferrari's of Kimi Räikkönen and Fernando Alonso – the latter unable to make an impact in front of his home supporters.

Jenson Button did well to haul his McLaren into the top ten positions, placing just ahead of Felipe Massa's Williams and the Red Bull of Vettel, which came to a halt in the opening minutes of the top ten phase.

Force India's challenging weekend continued, with Nico Hülkenberg and Sergio Pérez failing to make it past Q2.

Toro Rosso rookie Daniil Kvyat ended the day in 13th, ahead of Sauber's Esteban Gutiérrez, McLaren's Kevin Magnussen and team-mate Jean-Éric Vergne, who will drop to the back with his 10-place grid penalty.

Pastor Maldonado was the biggest name to drop out of the running in the opening knockout session, signalling a short red flag period after running wide at Turn 3, sliding across the track and hitting the concrete wall.

The former Spanish Grand Prix winner will join Vergne on the final row of the grid for tomorrow's race.

Adrian Sutil also fell at the first hurdle, the German lacking pace in Sauber's overhauled, lighter car.

Max Chilton comfortably beat Marussia team-mate Jules Bianchi to 18th, while rookie Marcus Ericsson out-qualified fellow Caterham driver Kamui Kobayashi for the first time in his Formula 1 career.
