- Rosberg on pole by 0.059s but runs off at Mirabeau on final laps to bring out yellows
- Hamilton unable to improve under yellows but beats both Red Bulls and Ferraris
- Massa taken out by Ericsson in Q1
for full Qualifying times.
Nico Rosberg took pole position at Monaco for the second year in succession after beating team-mate Lewis Hamilton in qualifying.
While the Red Bull pair of Daniel Ricciardo and Sebastian Vettel had looked quick throughout practice, it was left to the two Mercedes' to fight it out in the final part of qualifying and it was Rosberg who had the edge after the first runs. Then, on his second run, Rosberg ran down the escape road at Mirabeau to bring out yellow flags which scuppered Hamilton's attempts to improve. Rosberg was later investigated for the incident but the stewards decided no action was necessary.
Hamilton will line-up second on the grid ahead of the two Red Bulls – Ricciardo ahead of Vettel – while Fernando Alonso outqualified Kimi Raikkonen in an all-Ferrari third row. Jean-Eric Vergne will start from seventh ahead of Kevin Magnussen, Daniil Kvyat and Sergio Perez.
The Mercedes pace was first displayed in Q2 as both Hamilton and Rosberg finished over half a second clear of the rest of the field, with the two Red Bulls and Ferraris closely matched. Kvyat impressed with the seventh quickest time as both Toro Rossos progressed, while Perez and Magnussen also went through but Jenson Button struggled to put together his final lap and crawled across the line having aborted his attempt.
It was a disappointing session for Williams as Valtteri Bottas dropped out in 13th place and team-mate Felipe Massa failed to run at all having been forced to stop on track after being hit by Marcus Ericsson in the first part of qualifying.
Q1 was punctuated by two main incidents, with the first coming when Kvyat lost control of his Toro Rosso under braking for the Nouvelle Chicane and eventually slid sideways after almost catching the car twice. The front wing was wiped off against the barrier but Kvyat escaped more serious damage and still progressed.
Ericsson had already held up Nico Hulkenberg when he managed to collect Massa in an incident at Mirabeau. With Massa holding a wide line to allow the Caterham through, Ericsson carried too much speed in to the corner and lost the rear, sliding wide and forcing both cars in to the barrier. Massa attempted to continue but soon stopped on track a few corners later, which meant the end of his session despite having made it through to Q2.
The incident was part of a poor session for Caterham as they set the slowest two times, getting outqualified by both Marussias. Jules Bianchi was comfortably the best of the bottom four, 0.6s quicker than team-mate Max Chilton and ending the session closer to the two Saubers ahead of him than any of the other three cars behind.
