Lewis Hamilton is relishing challenge of faster Formula One cars
Lewis Hamilton says he believes the new faster Formula 1 cars this year will be a "massive challenge". The Mercedes driver said he had trained hard but had no idea whether he was fit enough for cars which could be four seconds a lap faster than 2016.
"I don't know if I'll be easily fit enough, or will struggle a bit or be super-underneath and need to work harder," the 32-year-old British driver said.
While confident, he said he did not know if Mercedes would remain in front. Hamilton lost the world title last year at least partly because he had worse reliability than Nico Rosberg.
But asked how much that hurt, he said: "Nowhere near as much as you think. It doesn't change my life. You just move onwards and hopefully upwards."
Hamilton said it would be "strange" not having Rosberg in the team following the German's retirement but added: "I have rivalry with everyone so it doesn't really matter who it is against."
