Mercedes boss Toto Wolff says he is delighted with the speed shown by the manufacturer at the Austrian Grand Prix, as the squad secured another 1-2 finish.
Nico Rosberg beat Lewis Hamilton to victory, while Felipe Massa's Mercedes-powered Williams collected third, as seven of the top 10 finishers used Mercedes power units.
"I'm very happy with the result, especially at my and Niki [Lauda]'s home circuit here in Spielberg.
"It's even more special because we have three Mercedes engines in the top three for the second year in a row; it couldn't be better.
"Nico drove a brilliant and dominant race - he got a great start, had the upper hand on pace and made no mistakes at all.
"Both boys were right on the limit, as you could see when Nico came into the pit lane sideways for his pit stop! As for Lewis, his race boiled down to the start and the pit stop; he lost out off the line, which we will need to analyse, then looked to have a snap oversteer as he left the pit lane and put two wheels over the line.
"From there, he just brought the car home and managed the gap to Felipe behind.
"Like in 2014, we are seeing the advantage swing from driver to driver across the races, and I'm sure they'll be battling all the way to the end of the season."
