Jenson Button says that there has been "no stone unturned" in the development of the Vodafone McLaren Mercedes MP4-28 that he will drive this season.
The team unveiled the car at the McLaren Technology Centre last Thursday after a parade of previous incarnations demonstrated the changing look of the vehicles over the years.
Button, who comes from Frome, admitted that the team will still have to work hard to ensure reliability when the Formula 1 season gets under way but added that lessons have been learnt from last year's campaign.
"We'll be working extremely hard during pre-season to ensure we go to the first race with bulletproof reliability," he said.
"Operationally, too, I think we've learned and developed from last year and that will help us run a much smoother and stronger campaign.
"We were extremely strong throughout the whole of the 2012 season but, for one reason or another, we couldn't quite pull it all together to challenge for the championships.
"That's something we want to address for 2013. I've seen just how closely everybody has been working together on this car and I think we've got the basis for a very strong season.
"The demonstration of some classic McLarens makes me feel incredibly proud to be a Vodafone McLaren Mercedes driver. I don't think anybody with a love for motorsport could fail to be moved by the sound and fury of the cars we saw.
"This year's car is the best we've ever made – I know the engineers have left absolutely no stone unturned in wringing out every ounce of performance from every available area.
"I cannot wait to get behind the wheel and attempt to carry forward the incredible legacy that lives beneath the skin of every single man and woman who works at McLaren."
Button has a new team-mate this year, with Mexico's Sergio 'Checo' Perez joining from Sauber, and says that the early signs indicate they will get along well.
But having been at McLaren since 2010 himself, the Frome Flyer believes that his knowledge of the team will stand him in good stead this year.
"I'm going into my fourth season as a Vodafone McLaren Mercedes driver and, more than ever, I know and understand the strengths and abilities of this team," he said. "This year is really about continuity and consolidation.
"Obviously, the biggest change for 2013 is my new team-mate, Checo. It's always interesting and inspiring to begin working with a new face and it already feels like a very positive working relationship."
Button began pre-season testing at Jerez on Tuesday ahead of the start of the first Formula 1 race of the season in Australia on March 17.
