Nico Rosberg secured pole position for the Spanish Grand Prix, with team-mate Lewis Hamilton setting the second fastest time.
Rosberg's time of 1:20.718s was over two tenths of a second quicker than Hamilton, with reigning champion Sebastian Vettel in third place.
Kimi Raikkonen took fourth, while home favourite Fernando Alonso was fifth. The Spaniard edged out Felipe Massa by just a thousandth of a second.
Romain Grosjean as seventh, ahead of Red Bull's Mark Webber. Sergio Perez surprised many by making Q3 and he set the ninth quickest time. Paul di Resta rounded out the top 10.
Neither Toro Rosso driver made it through to Q3 although Daniel Ricciardo and Jean-Eric Vergne came close with eleventh and twelfth. Adrian Sutil was thirteenth, while Jenson Button was only fourteenth.
Sauber's struggles continued. Nico Hulkenberg set the fifteenth quickest time, while Esteban Gutierrez was sixteenth.
It proved to be another disastrous qualifying session for Williams. 2012 race winner Pastor Maldonado could manage only eighteenth, behind team-mate Valtteri Bottas.
At the back, Giedo van der Garde was nineteenth, ahead of Jules Bianchi, Max Chilton and Charles Pic.
