Daniel Ricciardo secured his maiden pole position for Sunday's Monaco Grand Prix with a stunning fastest lap for Red Bull in an incident-filled qualifying session on Saturday.
The 26-year-old Australian, driving with supreme aplomb and great speed, mastered the unforgiving Monte Carlo street circuit with a best lap in one minute and 13.622 seconds.
This was enough to beat both Mercedes drivers comprehensively, championship leader German Nico Rosberg winding up second behind him by 0.291 seconds and defending three-time champion Briton Lewis Hamilton third, after suffering another engine problem.
Four-time champion Sebastian Vettel of Germany was fourth for Ferrari ahead of compatriot Nico Hulkenberg of Force India and Finn Kimi Raikkonen, in the second Ferrari.
Ricciardo set his time on a set of 'super soft' tyres with greater durability than the 'ultra softs' used by his rivals - a likely tactical advantage in Sunday's classic 78 laps race.
His Red Bull team-mate record-breaking Dutch teenager Max Verstappen crashed in the opening Q1 session and will start from the back of the grid.
Spaniard Carlos Sainz was seventh for Toro Rosso ahead of Mexican Sergio Perez of Force India and Russian Daniil Kvyat in the second Toro Rosso.
Two-time champion Spaniard Fernando Alonso was tenth for McLaren Honda.
