Jenson Button has revealed Ron Dennis' determination to get McLaren back to the front of the Formula One grid.
Button's fourth place on home turf at Silverstone earlier this month matched his best result since the season-opening race in Australia, where he was elevated to third in the wake of Daniel Ricciardo's disqualification.
The 34-year-old missed out on a place on the podium, and what would have been his first top-three finish at the British Grand Prix in his 15 years in F1, by just 0.8secs to Red Bull driver Ricciardo.
Although the result was agonising, it was another step in the right direction for a McLaren team who genuinely believed ahead of the race the circuit would not prove to their liking.
Fourth, however, is naturally far from good enough for McLaren, who have now endured 28 races without a victory, an eternity for a team accustomed to success.
Despite progress being made, it is not to the satisfaction of Group CEO Dennis as Button said: "There's still a lot of work to do.
"The philosophy has to be 'we did all right (at Silverstone), but tomorrow has to be a better day, and the day after, and the day after that', otherwise we're not going to catch the guys at the front.
"Looking at the speed of the Mercedes I would say we're not going to win this year, not unless they both fail.
"But they are so much quicker and, to be fair, we are going to have to build a better car than they have to beat them.
"That's not going to happen, but I suppose anything is possible. We were 0.8 of a second away from a Red Bull.
"But we all know we've a lot to do. I sat down with Ron at the end of the race and he's determined to make it happen, as we all are.
"We don't want to be fourth, and happy with fourth, even though it was a great weekend for us at our home grand prix.
"So he's pushing very hard, everyone's pushing very hard. It's not like we are limited with resources either.
"There is a lot going into this year to see improvements to ensure we start next year strong."
It is towards next year where McLaren are focusing, preparing a car for the arrival of Honda as power-unit suppliers to ensure they and the Japanese manufacturing giant hit the ground running in 2015.
It means any advantages and know-how acquired now will stand McLaren in good stead.
Racing director Eric Boullier said: "It says a lot about the strength of our race team we've recently managed to achieve some respectable results at circuits where we perhaps didn't expect to shine.
"We're aware those results weren't fully representative of the pace of our car, but were achieved because our race team has the experience and commitment to make things count when it really matters.
"Even if, on paper, the track in Germany suits us better than it seemingly did in Great Britain, we still need to maximise everything to be in a strong points-scoring position on Sunday afternoon.
"But there are no short-term answers: we're still pushing the development of the car and are hopeful the lessons we learn during this season will have a positive effect on the development of next year's car."
Ahead of the race, home star Nico Rosberg has signed a multi-year extension to his contract with Mercedes.
Currently in his fifth campaign with the team, and in with his best opportunity of landing the world title as he leads team-mate Lewis Hamilton by four points, Rosberg said: ''I am very proud to drive for the Formula One Silver Arrow of the modern era.
''As a German, the heritage of Mercedes-Benz is very special for me, and I am proud to be able to represent the best car brand around the world.
''It has been a difficult road to get to where we are now, but everybody kept believing and thanks to the fantastic support from Mercedes-Benz, we are now leading the way in F1.
''There has been big progress during the past year, building up our structure, management and capability for the future.
''We have an awesome team and I am confident we have the right people in place at every level.
"I'm looking forward to the next years together, when we will keep pushing to win even more races and, hopefully, championships.''
