Nico Rosberg: 'Consistency is key for title'

Nico Rosberg believes that consistency is key to winning the world championship this season, as the German prepares for the Hungarian Grand Prix.

Rosberg has been involved in a constant battle with Mercedes teammate Lewis Hamilton this campaign, but remains ahead in the drivers' rankings by just 14 points.

Rosberg told reporters: "We each have strengths and weaknesses, which is normal.

"It is always going to be a tight battle and I just need to be a little more consistent than the other guy."

Hamilton is without a pole position during the last five races but holds a strong record at the Hungarian Grand Prix, winning four of the last seven.

Hamilton was fastest in the second practice on Friday.
