Ross Brawn is convinced Mercedes can carry their momentum into the second half of the season in their pursuit of this year's Formula One world titles.

Seven pole positions in the last eight grands prix and three wins in the last five have made Mercedes the main challengers to Red Bull.

Heading into the summer break, Mercedes driver Lewis Hamilton trails Red Bull's championship leader, Sebastian Vettel, by 48 points, with Mercedes 69 adrift of the reigning champions in the constructors' race.

"We're starting to convert the pole positions into race results," said Mercedes' team principal Brawn. "But we're far from perfect. We've still a lot to do, but the momentum for the second half of the season is really strong."
