Button determined to continue push for title despite gap to Vettel

Button scored his second win of the season in last weekend's Hungarian Grand Prix, but Red Bull rival Vettel finished in second and increased his lead in the championship.

The McLaren driver is 100 points behind the German.

Button conceded it will be a challenge to catch Vettel, but he insists he is not giving up.

"I'm 100 points behind Sebastian, so that's going to be challenging, but we like a challenge," said Button. "I never give up, so let's see what happens.

"I'll take each race as it comes and then look at the points at the end of the year."

Button admitted he was very encouraged by McLaren's progress in the last couple of races, with the team having won back-to-back events in Germany and Hungary.

"Our race pace was very strong, but I don't think there was much between us, Ferrari and Red Bull," he said. "We've won three of the last five races and each of our major rivals has won just one apiece during that time, so we're doing something right.

"To win with Lewis in Germany and me in Hungary proves that McLaren is pushing, developing and challenging the cars around us with genuine pace in the car."

Team-mate Lewis Hamilton, the winner at the Nurburging, is also bullish about his prospects for the upcoming races, the Briton adamant that he can score more victories.

"There are 200 points up for grabs and I enter all of the races believing I can win them," he said. "We're about to visit some really special venues: Spa-Francorchamps, Monza, Suzuka and Interlagos are some of the greatest tracks in the sport. You really feel their soul and their history.

"We're going to these tracks with three teams battling with similar pace at the top, it's going to be a competitive and dramatic run down to Brazil and the end of the season."
