McLaren managing director Jonathan Neale says the team hopes to benefit from a series of upgrades at Silverstone this weekend having trialled a series of tweaks during a straight-line test in Spain ahead of the British Grand Prix.
The session at the Idiada facility allowed the team to look at ways in which it can try and improve the performance of the MP4-28 after a tough start to the campaign that has seen both Jenson Button and Sergio Perez off the pace of the front-runners so far.
Having failed to even score last time out in Canada, which ended its long run of points scoring finishes, the team will now aim to try and bounce back on home soil and Neale said the straight-line session was being used to try and gain a better understanding of the car.
"The only issue with our car is we lack downforce and that is what we are trying to create at the moment," he explained in a Vodafone McLaren Mercedes phone-in session. "We've got a range of upgrades for the weekend but we're not there [in Spain] just testing parts, but testing some fundamental understanding issues as well.
"We'll wait and see on Friday afternoon at Silverstone as to what remains on the car for Saturday to know how successful it has been, but we won't know until the running is over finally what package we'll take to Silverstone."
Neale admitted that points had to be the aim for the team in the British Grand Prix but admitted it may be a step too far to think that a podium finish could be on the cards.
"We want to get both cars into Q3 and then race hard for good points," he said. "It would be great if the guys could get a podium out of it but I think on recent performance that could be quite challenging.
"There isn't going to be a golden bullet. We are pushing hard but the reality of the situation is there is still a big gap from us to the front of the grid."
