Despite the typically damp Spring climate in Brackley, spirits were high in the factory as Lewis arrived for his final visit to HQ before the season begins.
Amongst the engineering meetings, sponsor appearances and team kit review meetings, Lewis spent time checking out the work being done around the factory ahead of the season-opener in Australia.
And just after lunch, in the team's post-testing debrief, he took a moment to deliver some words of encouragement to his team-mates.
"When I come to the factory at the beginning of the year and see the car being designed and built in all these different areas, I am always fascinated," he admitted.
"The parts are brought together and make such a work of art. I am just amazed at what everyone is able to achieve and I can only say that it is the greatest feeling in the world when I get to that first test and get in the car.
"I feel incredibly blessed to be one of only two people to get to drive this machine."
