Silverstone, England - Lewis Hamilton has delivered an ominous warning to his Formula One rivals by vowing to improve on his almost flawless championship-winning campaign in his Mercedes.
The British driver emerged from his winter hibernation at Silverstone on Wednesday to see the car he hopes will fire him to a sixth world title.
The 34-year-old won 11 of the 21 races in 2018 to beat Ferrari's Sebastian Vettel and secure his fifth championship with two rounds to spare.
And as he enters the first campaign of the new two-year Mercedes deal that will earn him £40 million (R712m) a season, a fully refreshed Hamilton is ready to extend his dominance of the sport.
"2018 was a great year, but I feel like 2019 can be even better," he said. "I want to achieve more, I want to continue to keep pushing. I feel energised and I am ready to attack."
