Williams honors its 1981 championship-winning car with a distinctive livery for the Spanish Grand Prix.

Williams will unveil a special 1981-inspired design on its FW48 during this weekend's Spanish Grand Prix in Madrid.

The unique color scheme of white, green, and navy blue pays tribute to the FW07C, the vehicle that secured the constructors' championship in 1981. Notably, that year also marks the last occasion Formula 1 graced the Spanish capital, with Alan Jones and Carlos Reutemann racing at the nearby Circuito de Jarama.

F1 is set to return to Madrid for the 2026 season at the newly built Madring, featuring a 22-turn configuration that combines permanent circuit sections with public roadways.

The Grove team showcased the new livery at a fan event held in Madrid's Plaza de Callao on Tuesday evening. 

"Our goal to reclaim our position at the front of the grid is fueled by, inspired by, and shaped by everything we've accomplished in the past," team principal James Vowles stated.

"I am extremely proud to celebrate this through [title sponsor] Atlassian’s special livery, linking the team we were at Jarama with the team we are evolving into today through focused collaboration, enhanced technological innovation, and genuine creativity.

"The car looks amazing, and I am eager to see it racing around Madrid."

Carlos Sainz, gearing up for his home grand prix, serves as an ambassador for the Madring circuit. "It's a significant race for me this week - my first genuine home race in Madrid, and it's been even more special witnessing this circuit come together over the last few months," the Spaniard expressed.

"It's an honor to bring F1 back to Madrid, the place where I first drove a kart, and to compete in front of the incredible home crowd."

Both Sainz and his teammate Alex Albon will don new race suits that reflect the distinctive livery.

The Spanish Grand Prix is scheduled for Sunday, September 13.
