The 40-year-old will team up with Charles Leclerc at the Scuderia this year as he targets an elusive eighth world title, having endured three seasons of frustration at his former employers.
Hamilton is set to make his first appearance in a Ferrari car at the team's private test track in Fiorano, albeit in their 2023 car, and will complete further testing in Barcelona.
Hamilton begins Ferrari era
The seven-time world champion was unable to participate in the 2024 post-season tyre test in Abu Dhabi last December, after he embarked on a farewell tour with Mercedes.
Hamilton has been eager to share his excitement about the prospect of lining up for Ferrari in 2025, but also admitted it was an incredibly difficult decision to leave Mercedes, with whom he won six drivers' championships.
His shock departure was also felt by his former boss Toto Wolff, who spent much of last season trying to find a replacement for the Brit, with Kimi Antonelli eventually selected.
