Honda say they have the best driver line-up in Formula One as they embark on their first season as a constructor since 1968.

Boss Nick Fry said he was "optimistic" Jenson Button and Rubens Barrichello would break a seven-year win drought for the team formerly known as BAR.
"This is the best driver line-up in our team's history. It is also the best team of drivers on the grid," Fry said.
Button also said he was "confident" of winning his first Grand Prix in 2006.
Fry said that the combination of Honda's two race drivers together with their experienced and highly-rated English test driver Anthony Davidson was better than that of any other team.
"You can debate the merits of any one individual but I think our three put together is the best team," he said.
Fry said the addition of Barrichello, who has moved after six years as Michael Schumacher's number two at Ferrari, had made a big difference.
"Rubens has been exactly what we expected. He's technically very strong, he knows exactly what he wants," Fry said.
"Technically he's a big asset to the team and he's working very well with both Jenson and Anthony. His maturity and his depth of experience is going to be a huge asset to the team.
"We are pleased we've got two great drivers so we go forth optimistically. There's a great atmosphere between the two of them at the moment," Fry added.
Honda took complete control of BAR last year in an attempt to end six years of frustration as an engine supplier.

Honda racing chief Yasuhiro Wada said: "I personally cannot stand not winning for more than five years. Ideally I would like to see a win this year."
The Englishman has not won a race since his debut in 2000, but said the work Honda had done with an interim car so far in pre-season testing had encouraged him.
"We've achieved a lot in winter testing with our concept car," he said.
"I'm confident that all the determination will be rewarded this year and I've done my part by working even harder on my fitness to ensure that I'm in the best possible shape for the season ahead."
