The FW48 will hit the Madring in white and green this weekend, a colour scheme borrowed from the championship-winning FW07C driven by Alan Jones and Carlos Reutemann in 1981.

That season was also the last time Formula 1 raced in Madrid. Williams took Jones and Reutemann to the Circuito de Jarama and left the year with a successive constructors’ title in the bag.

Carlos Sainz pulled the covers off the one-off design at the Williams Fan Zone on Plaza del Callao in the Spanish capital on Tuesday evening, alongside title partner Atlassian.

The FW07C carried Williams through the defence of their constructors’ championship in a season the team still treats as foundational. Team principal James Vowles tied that era to the current rebuild.

“Our mission to get back to the front of the grid is drawn from, inspired by and informed by everything we’ve done before,” Vowles said.

“I am incredibly proud to celebrate that, through Atlassian’s special livery, connecting the team we were at Jarama with the team we are becoming today through focused collaboration, improved technological innovation, and real creativity.”

Sainz races at home, in Madrid, for the first time

For Sainz, the Madring is a home race in the most literal sense. It is his 13th Spanish Grand Prix but the first held in his home city.

Team-mate Alex Albon arrives chasing Williams’ first points since his eighth place at Monaco earlier in the season.
