Nico Rosberg says he expected Red Bull to be more competitive after Mercedes was comfortably quickest during practice for the Hungarian Grand Prix.

Lewis Hamilton topped the timesheets at the end of both sessions, with Rosberg within a quarter of a second on each occasion and no other car inside 0.6s of the fastest time. Speaking after FP2, Rosberg said he had been pleasantly surprised by the pace shown by Mercedes on a tight track with few straights.

"It seems that we are quick today, which is surprising because I thought the engine wouldn't count for much on this track," Rosberg said. "I thought the others would be much closer, especially Red Bull. It seems like we're quick and that's great to see."

Rosberg said the main focus of his work during practice was to set the car up for qualifying as he expects pole position to be crucial between himself and Hamilton.

"I have to focus more on qualifying here because it's important to be ahead. It's like a city track here because there are so many corners and bumps and kerbs and no straights to relax."

And Rosberg added he believes Mercedes has been helped by the ban on FRIC suspension systems based on the performance on Friday.

"If anything it has given us an advantage which is awesome to see for now, although I don't know about tomorrow."
