"It was a perfect weekend," said Rosberg. "Perfect to be on pole and then to win the race like this. The car has been awesome all weekend. Really perfect."Finally I got a perfect start, it's been a long time coming.

"I'm just enjoying the day today. Winning here in Barcelona is great and then we'll look forward to the next race."
