McLaren boss Martin Whitmarsh has said several factors are to blame for the teams' woes this season.
McLaren opted to go radical with the MP4-28 and that decision has backfired badly. Indeed the Woking-based squad is currently only sixth in the Constructors' Championship with 37 points on the board, 22 points behind Force India and a massive 182 points behind the leaders, Red Bull.
The last two races have been particularly painful and both Jenson Button and Sergio Perez failed to score in Canada and Britain.
“Well I have my own views," Whitmarsh replied to Sky Sports F1
ahead of this weekend's German GP at the Nurburgring, when asked if the squad has pinpointed the issue with the MP4-28, "and I have expressed those to the engineering team as you might imagine.”
“There are a number of things [wrong with our car], it is not usually one issue, and you have to remember F1 is a massively competitive environment and if you are one or two per cent out of that sweet-spot you are nowhere and that is unfortunately where we are.
“We took some decisions looking back on now that we regret and the important thing is to learn from that.
“We don't give up, we want to race, we want to win a race this year but we have made it pretty tough for ourselves, but importantly with the brand new regulations for next year we need to make sure we come out strong and put our resources into that.
“Next year is an important year and of course 2015 is another important year for McLaren and we have to look ahead. I think we have an exciting future ahead of us. We are used to coming to races and thinking we can win - when you are thinking you need to luck in to do that it is a different mentality.”
Asked about the plan now for the remainder of 2013, Whitmarsh reiterated that the team's focus is on 2014, although he added that it doesn't mean the MP4-28 won't benefit from some upgrades during the rest of the season.
“Clearly we have to make sure we come out strong in 2014. We have some development bits here and there like development angles that are relevant to next year. But there are areas of normal development like the exhaust that we are not going to spend too much time on because the exhaust is very different next year and not significant,” he explained.
"Whereas the front-wing for example, we have a radically new front-wing coming that is relevant to next year so we can still do that. So what we are doing is developing parts for next year, but anything we can bring to this car we are going to do so.
“We are going to carry on fighting and bringing parts to this car but we have to be realistic about where we are this year - and probably a break from convention for McLaren as normally we are fighting for wins of the championship and you don't have the luxury of taking the foot off the gas, and it doesn't feel good to be doing that - but we have to make sure we are doing the right things for next year.”
