The 40-year-old finished second overall for the day but only 0.031 seconds behind Williams’ Carlos Sainz. Hamilton replaced Sainz at Ferrari as Sainz joined Hamilton at the end of last season.
The new season of the Formula 1 begins on March 16 in Australia.
“I am really enjoying the car. We’re slowly bonding, I think,” Hamilton told television reporters at Bahrain’s Sakhir circuit.
“Yesterday was a so-so day, it was just OK. But yesterday we got through all our run-plan.

“Today was a bit more of getting to explore a bit my interaction with my engineer. But so far I really enjoy driving this car,” added Hamilton, who won six of his titles with Mercedes and one with McLaren.
The enjoyment was limited for much of last year, with the Briton unhappy with his Mercedes’ handling.
Hamilton said he was getting up to speed gradually with his new surroundings.
“We’re really just focused on doing our job, we’re not watching everything else that’s happening. We’re literally just trying to make sure that we’re learning our processes in the car,” he explained.
“With every lap and every session that I get, I’m learning more about the car, getting more and more comfortable with all the completely different control systems that we have.
“I’m still in the learning phase of understanding the rear suspension, the front suspension, all the different settings that they have for those and the terminology that they use for them as well,” he added.
“It likes to be driven differently. And that’s a really fun journey, learning that… I feel that the car is responding to my inputs. Today was a positive day and making those incremental steps with the setup.”
