Team Abt's Edoardo Mortara leads an all Audi front row alongside DTM points leader Jamie Green after converting upon his weekend-long practice stranglehold at the Red Bull Ring.

The Audi driver went marginally quicker than he managed during FP2 and duly set a 1 minute 24.714 second lap to hand himself his first pole position of 2015 and the primary grid slot for this evening's opening race.

Unlike his strategy in practice, Mortara kept his powder dry until his very last run of the 20 minute session, where he disposed of the high flying Mercedes C63's of Pascal Wehrlein and Paul di Resta.

The two HWA C63's had set the benchmark following the first plethora of runs after the pair both set low 1 minute 25's within 0.006's of each other.

A red flag triggered by the stricken Audi RS 5 of Miguel Molina prolonged the tension between the first and second runs with eight minutes to go, but it wasn't enough to deter the mindset of Mortara's final act.

Although Wehrlein and Di Resta did both manage to improve it wasn't enough to keep the leading Audi's charge at bay as Team Rosberg's Green also demoted the pair to the second row.

Wehrlein's effort at the top was all the more impressive considering his Mercedes C63 - along with Audi's Mattias Ekstrom - carries the most amount of performance ballast this weekend.

Team RBM's Augusto Farfus took over the mantle as the lead BMW from Marco Wittmann in fifth. Like Wittmann's practice exploits, Farfus was also the only driver the fly the flag for the M4 within the top-ten.

The next BMW to feature was, in fact, Wittmann but the defending champion could fare no better than twelfth.

HWA's Christian Vietoris will share the third row with the Brazilian while Robert Wickens and Gary Paffett locked out the fourth row for Mercedes.

Audi had the final say in the positioning for the remainder of the top-ten and it was Abt's Ekstrom and Team Phoenix's Mike Rockenfeller who completed the upper echelons of the 24-car field.
