Sainz begins new chapter with Williams in Abu Dhabi test
Carlos Sainz makes his Williams F1 debut in Abu Dhabi, completing seven laps and beginning a new chapter after leaving Ferrari, marking a significant career transition.
Ferrari departure sets stage for fresh F1 challenge
Carlos Sainz has officially kicked off his Williams Formula 1 journey, making his debut with the British team during the post-season test at the Yas Marina Circuit.
The Spanish driver completed his first laps in a plain white race suit, signaling a definitive break from his four-year tenure with Ferrari.
Maiden Williams run
On his first official day with Williams, Sainz completed seven laps, recording a best time of 1m26.484s.
While significantly slower than his qualifying time from the previous weekend's Abu Dhabi Grand Prix, the run represented an important first step in his new racing partnership.
The test provides a unique opportunity for Sainz, with teams now allowed to enter two cars, enabling a more comprehensive preparation for the 2025 season.
Tyre testing and etchnical preparations
Sainz benefits from a privileged position in the test, able to run the homologated version of Pirelli's 2025 tyres.
He will have access to 10 sets of tyres, including the new ultra-soft C6 compound, which represents an exciting technical addition to Pirelli's range.
This strategic testing allows teams to collect valuable data for the Italian tyre manufacturer without a predefined programme.
Career transition and team dynamics
The Abu Dhabi test marks a significant milestone in Sainz's career, representing his fifth team in Formula 1.
His move to Williams came after being displaced at Ferrari by seven-time world champion Lewis Hamilton, a transition that underscores the constantly shifting dynamics of top-tier motorsport.
Broader F1 context
The test also provides insights into other team strategies, with Williams introducing Formula 3 race winner Luke Browning as its designated rookie driver.
Meanwhile, the RB team's Yuki Tsunoda is getting his first opportunity to test the Red Bull F1 car, amid speculation about potential driver changes in the energy drink giant's flagship team.
Sainz's arrival brings a wealth of experience to Williams, a team looking to rebuild its competitive position in the championship.
His extensive background with Toro Rosso, Renault, McLaren, and Ferrari positions him as a potentially transformative figure for the British squad.
