SPIELBERG, Austria (AP) — Formula One returned to business as usual Sunday as Nico Rosberg led Lewis Hamilton at the Austrian Grand Prix for the sixth 1-2 finish by Mercedes.
Red Bull's Daniel Ricciardo won the Canadian GP two weeks ago and Williams' Felipe Massa took pole position for Sunday's race but this had little effect on Mercedes which had missed out on the front row of the grid for the first time this season.
"I was still very confident going into the race and knew I could win starting from third," said Rosberg, who celebrated his third win of the year and sixth overall as he extended his lead in the drivers' championship over Hamilton to 29 points — 165 vs. 136.
"I am extremely happy," the German said. "Extending my lead was the main goal coming into this race."
Williams' Valtteri Bottas came third for his first career F1 podium while teammate Massa took fourth. Four-time champion Sebastian Vettel quit the race on lap 36 after overcoming engine problems early in the race.
Rosberg succeeded where his father Keke had just failed 32 years ago, when he came up 0.05 short of Elio de Angelis at the 1982 Austrian GP.
However, Keke Rosberg went on to become world champion that year, a feat Nico Rosberg is reluctant to think about yet.
"29 is a nice gap but it's still so early in the season," he said.
Hamilton, who was ninth after qualifying, earned four places from a blistering start and won another place to work his way up to fourth in the opening lap.
"It was a good start, one of the best starts I've ever had," the 2008 F1 champion said. "To get from ninth to second and then pressure Nico shows the pace I had this weekend."
Rosberg immediately overtook Bottas but lost that position again shortly after the first turn. Massa dropped from pole to fourth after the top four had their first pit stops and never threatened the leaders again.
Sergio Perez remained in the lead until the 27th, overtaken by Rosberg who accelerated for the fastest lap so far to create distance on Hamilton, who got stuck behind Perez.
The Mercedes drivers went 1-2 from lap 47 on but Rosberg kept Hamilton at bay, denying him a chance to overtake. The British driver saw his chances reduced as the two pit stops in the race cost him 1.9 seconds more than Rosberg who relaxed at the end.
"I felt comfortable in the last lap," Rosberg said. "It wasn't that close."
The race once more confirmed Mercedes has best adapted to the introduction this season of the 1.6-liter turbocharged V6 engines with the build-in energy recovery system. Hamilton won four races in a row while Rosberg never finished worse than second.
