Having switched from McLaren to Mercedes this season, the changes for the British driver have been quite evident.
Signed with the German manufacturer for three years, the 2008 world champion is sure that his move was the right one suggesting that the current environment is much better suited than it was at Woking.
"We still have sponsors, we still have sponsor appearances and filming days, so there is not a huge, huge difference in the way they go about their business,” Hamilton was quoted saying by Sky Sports.
"But the focus is on the driver, the driver's performance, the driver being ready for the job at hand - that's the one thing I'm noticing is a little bit better here,” he pointed out. “They want me to be as ready as I can possibly be physically and mentally and want to do everything possible for that be taken care of - and that's something great to experience.”
The 28-year-old added that he feels he can now “improve as a person and as a driver as whole” at Mercedes indicating that he was stifled at McLaren.
Mercedes was the quickest car in the final two days of the pre-season tests emerging as a potential threat to the frontrunners, and Red Bull acknowledged that challenge.
"Their car looks quick, and with Lewis joining the team they will naturally take a step forward. He is worth lap time, which is why they signed him,” Red Bull team principal Christian Horner was quoted saying by Reuters.
"Lewis, as we all know, is a world-class driver, and he is going to raise their level, and they will be a factor this year," he added.
