Jenson Button says McLaren is working hard to fix the reliability issues which have plagued the squad across recent events, as it bids to improve at its home race in Britain this weekend.
Button scored McLaren's first points in Monaco but failed to finish in Canada and Austria.
Team-mate Fernando Alonso has not reached the end of a race since Bahrain, with three mechanical failures followed by a crash-related retirement in Austria.
Button says that McLaren needs to work on its reliability but has been encouraged by the mileage racked up in testing last week.
"It was great that Fernando and Stoffel [Vandoorne] were able to do some positive running in Austria during the test, so we’ve firmly put the disappointments of race day behind us and I’m really looking forward to arriving in Silverstone," said Button.
"We’re still struggling to achieve consistent reliability, so we’re working really hard to find solutions to the issues we’ve been facing.
"Saying that, having two trouble-free days of running at the test has been a great motivation, and we’re continuing to push for more progress in this area."
Button added that irrespective of his position in the pecking order, he relishes racing in front of his home crowd.
"It feels great to be heading back to Silverstone – a place I love going to every year – and it’s a real privilege to be able to race in front of my home fans," he said.
"No matter what happens during a race weekend, the fan support always makes the whole event extra special: even though this will be my 16th outing at the British Grand Prix, seeing the Union Jacks out in the grandstands and the roar of the crowd still gives me goose bumps every time - it really is a magical feeling."
