- Rosberg wins by 1.9s as Hamilton recovers from ninth
- Bottas takes first F1 podium in third ahead of Massa
- Alonso fifth while Vettel retires
Nico Rosberg won the Austrian Grand Prix from team-mate Lewis Hamilton to extend his championship lead to 29 points.
It was a case of damage limitation from Hamilton, who started the race in ninth place but was directly behind his team-mate within a lap and remained no more than 2.5s behind throughout the race. However, once the two Mercedes cleared the Williams pair of Valtteri Bottas and Felipe Massa, Hamilton never looked likely to threaten Rosberg as both managed braking issues.
Bottas took the first podium of his F1 career with third place, beating pole-sitter Massa in to fourth as Massa had to withstand late pressure from Fernando Alonso. Sergio Perez capped a fine race with sixth place having started from 15th, opting to run long on the soft tyre at the start of the race.
It was a strong showing from Williams, with Massa leading the first stint and Bottas slotting in to second place after losing out to Rosberg off the line but repassing the Mercedes before Turn 2. Hamilton made a storming start to go from ninth to sixth after the first corner, fifth after Turn 2 and fourth out of the penultimate turn.
Rosberg was first of the leading four to pit, releasing Hamilton in to clear air and straight on to the back of Bottas. However, a slower stop ensured Hamilton rejoined behind his team-mate, with Massa next to stop and both Mercedes able to get ahead.
Bottas stopped last of the leaders and emerged between Rosberg and Hamilton, with Perez holding the pack up as he inherited the lead having yet to pit. Rosberg and Bottas both got through at Turn 2 on lap 27, but Rosberg failed to gap the Williams and even came under pressure from Bottas having run wide at Turn 1.
It was after the second round of pit stops that both Mercedes finally were ahead of the two Williams and could ease away, with Hamilton staying close behind Rosberg but unable to put enough pressure on his team-mate.
Bottas was able to manage his pace in the final stint to take third - 8.1s behind race winner Rosberg - while Massa faded in fourth but had enough pace in hand to keep his former team-mate Alonso at bay.
Running on the supersoft tyres for the closing laps, Perez passed Kevin Magnussen with five laps to go after getting a better exit from Turn 1. Behind them, Daniel Ricciardo snatched eighth place from Nico Hulkenberg on the final lap with an impressive pass around the outside of Turn 4.
It was another frustrating day for Ricciardo's team-mate Sebastian Vettel, however, as he retired midway through the race. Having ground to a halt on the second lap due to a loss of drive, Vettel managed to get the car moving again a lap down before Red Bull called him in to the garage on lap 35.
Kimi Raikkonen took the final point in tenth ahead of Jenson Button and Pastor Maldonado, while both Toro Rossos retired as Daniil Kvyat suffered a right rear puncture and Jean-Eric Vergne was hit by brake failure.
The result extends Rosberg's championship lead beyond a race win, while Williams moves up to fifth place in the constructors' championship - 13 points off third-placed Ferrari - after scoring its first podium since 2012.
