Team Rosberg's Jamie Green has denied Antonio Felix da Costa pole position in dramatic circumstances after snatching the top-spot away from the BMW driver in the dying seconds at the Red Bull Ring.
Da Costa set what turned out to be his best lap early in the session, meaning the Portuguese driver led the vast majority of the running.
Having initially survived the threat posed from his BMW stablemate Timo Glock posed during the final minutes, Da Costa looked odds on for pole position agonisingly missed out as Green saved his best till last.
Green's first two sectors were actually marginally slower than Da Costa's but a powerful end to his flyer allowed the Brit to leapfrog the BMW by a mere 0.002s.
Glock was third aboard his RMG prepared BMW M4 but could quite easily have gone to pole had the former F1-driver not lost the rear at the final corner.
Maxime Martin joins his BMW counterpart on the second row in fourth while Edoardo Mortara - unable to translate his practice pace into raw qualifying speed - had to settle for fifth.
Mortara's best time set during practice would have been good enough for pole position.
BMW occupied all but one of the remaining top-ten grid slots with Audi's Mike Rockenfeller proving to be the only exception in tenth.
Rockenfeller shares the fifth row with BMW's race one winner Marco Wittmann but trails Augusto Farfus, Bruno Spengler and Tom Blomqvist.
As Audi and BMW fought it out at the front, Mercedes notably struggled to generate the last push they needed to surge up the order.
In what was a ferociously contested session, Robert Wickens ended up as the top Mercedes runner in 15th despite setting a time just 0.378s away from pole.
The lack of Mercedes speed was compounded by championship leader Paul di Resta qualifying plum last for the second race.
