Lewis Hamilton has delivered a warning to his F1 rivals by vowing to improve on his title-winning show. The British driver emerged from his winter hibernation at Silverstone on Wednesday to get his first taste of the car that he hopes will fire him to a sixth world title.

Hamilton, 34, won 11 of the 21 races in 2018 for his fifth title, with two rounds to spare. As he enters the first campaign of the new two-year Mercedes deal that will earn him £40 million (Rs 370 crore) per season, he's ready to extend his dominance. "2018 was a great year, but 2019 can be even better. I want to continue to keep pushing. I'm energised and ready to attack."
