Speaking at the Circuit de Catalunya after testing on Thursday, Hamilton – who had been asked about the difference between the two teams – said that he now had more time to concentrate on his driving.
"We still have sponsors, sponsors' appearances and filming days. There is not a huge difference." But he then added: "The focus is on the driver, the driver's performance, the driver being ready for the job at hand. That's one thing I'm noticing is a little bit better here.
"It's just a new environment. I'm absolutely loving it. They're making a huge effort at communicating with me and making sure we're up to speed ahead of the first race."
Hamilton also made a peace offering to his former friend Adrian Sutil after the German's return to Formula One had been confirmed by Force India.
Hamilton, fast and combative, is hardly the sport's most obvious disperser of olive branches. But he had emailed Sutil, saying: "I had said a prayer for him, that I really hoped he got the seat because he deserved it."
Their friendship was fractured, perhaps terminally, a year ago when Sutil said: "Lewis is a coward. I don't want to be a friend of such a person. He is not a man." Sutil had been upset by Hamilton's refusal to appear as a defence witness after he had been given an 18-month suspended prison sentence and fined £167,000 after being found guilty of grievous bodily harm. He had assaulted the Lotus executive Eric Lux in a Shanghai nightclub in 2011.
Sutil suggested that his relationship with Hamilton was still extremely cool when he said: "I'm not in contact with him any more, so we have no relationship at the moment. I've not seen him, I've not spoken to him. For sure, I will meet up with him but I don't know what will happen."
But Hamilton appeared keen to be friends again. He said: "I emailed him on the way here as soon as I found out and congratulated him. I haven't heard back from him but I am sure at some stage we will get to talk."
Sutil said he deserved a second chance in Formula One. "Everyone can make mistakes in life," he said. "If you never make mistakes you will never grow. I don't think there is a single person here who never made a mistake. My one was maybe a different one and was very public. There are others probably even worse but no one talks about them."
Meanwhile, the future of the Marussia driver Luiz Razia is in considerable doubt. The team signed the Brazilian earlier in February but it is now understood the driver has run into difficulties with his sponsors.
