Lewis Hamilton has no regrets over his jump to Mercedes next season, again dismissing comments from McLaren team principal Martin Whitmarsh that the Englishman was having second thoughts about his move.
In an interview with the official Formula One website, Whitmarsh said he believed Hamilton had at times regretted his decision.
Speaking ahead of this weekend's US Grand Prix in Texas, Hamilton says he was a little surprised to hear that, it's absolutely not the case.
Hamilton says he's been with McLaren such a long time so he's sure everyone has some emotions within the team and he's still giving 100 percent for the last two races.
He says while it's quite emotional, he's very, very happy with the decision to move to Mercedes.
Hamilton will replace retiring seven-time world champion Michael Schumacher at Mercedes next season, ending a long-standing relationship with McLaren, who spotted his talent as a youngster racing go-karts.
Hamilton will start Sunday's race at the new Circuit of the Americas as the last driver to win a US Grand Prix with his victory at Indianapolis in 2007.
