Lewis Hamilton has delivered an ominous warning to his Formula One rivals by vowing to improve on his dominant championship-winning campaign in his Mercedes car.

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.

Hamilton, 34, 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 (Dh190m) 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."

Hamilton, who will be partnered at Mercedes for a third successive season by Valtteri Bottas, was set to get his first taste of the new Silver Arrows during a private filming event at Silverstone on Wednesday.

The British driver has kept a relatively low profile over the off-season, spending time in America, while also attending the Super Bowl earlier this month.

"I had a great Christmas with my family and then I went snowmobiling, I went skiing, I went surfing with Kelly Slater, which was amazing," Hamilton said. "I completely switched off from racing for a while, trying to focus and re-centre myself and training hard for the new season.

"I'm really looking forward to the next step of our journey together with Mercedes and embarking on what's not been done before.

"This is my seventh year with the team and the energy and the determination within the team are really inspiring."

Mercedes team principal Toto Wolff said: "When we met after the winter break, Lewis was refreshed. He's extremely hungry and wants to start racing again."

Pre-season testing gets under way in Barcelona on Monday before Hamilton starts his championship defence in Melbourne on March 17.
