Jenson Button has described McLaren's MP4-28 as "the best [car] we've ever made" after its launch on Thursday.

The new car was unveiled at the McLaren Technology Centre in Woking by Button and his new team-mate Sergio Perez. Button won three races in 2012 but was unable to challenge for the championship as reliability problems undermined the pace of the MP4-27. Button said that McLaren has worked hard to eradicate those issues and that he's eager to start testing the car at Jerez next week.

"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," Button said. "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.

"We'll be working extremely hard during the pre-season to ensure we go to the first race with bulletproof reliability. Operationally, too, I think we've learned and developed from last year, and that will help us run a much smoother and stronger campaign.

"This year's car is the best we've ever made - I know the engineers have left absolutely no stone unturned in wringing 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."
