The W15 car is due to be given its track debut on the short international version of the circuit, with Hamilton and his team-mate George Russell both making brief appearances on what is classed as a 15km demo day.
The first proper running will be in the form of a 200km filming day in Bahrain on Tuesday, on the eve of the start of official testing.
This year's car is hugely significant for the Brackley team after two disappointing years since the start of the current ground effect regulations era in 2022.
The W13 struggled badly with bouncing and porpoising, and while Russell scored a victory at Interlagos, the team slipped to third in the constructors' championship.
Last year's W14 did not represent the hoped for step in performance and underwent a major revamp after just a few races.
