FW07B
The blue-and-yellow revolution that cemented Williams as a Formula 1 powerhouse.
The Williams FW07B stands as one of the most dominant and transformative machines in Formula 1 history. Evolving from the successful FW07 chassis that carried Alan Jones to the 1980 World Championship, this updated version was introduced mid-1980 as an evolution of the FW07. It was used by both Alan Jones and Carlos Reutemann in the latter part of 1980, with Jones winning the 1980 Canadian Grand Prix in the FW07B. However, the FW07C was the car used in 1981.

Lore & Background
The car is forever associated with the rise of Carlos Reutemann, whose aggressive yet precise driving style complemented the chassis's handling perfectly. However, its legacy extends beyond individual drivers; it proved that a mid-field team could evolve into championship contenders through technical innovation rather than budget alone. The FW07B era marked a key chapter in Williams' golden age, establishing a culture of engineering excellence that would define the team for decades.
In Their Own Story
The rain lashed against the cockpit canopy at Zandvoort, turning the Dutch circuit into a slick mirror. Inside the blue-and-yellow FW07B, Carlos Reutemann gripped the wooden steering wheel, feeling the subtle chatter of the Cosworth DFV engine fighting for traction. As he navigated the hairpin, the car's refined suspension absorbed the undulations with a confidence that felt almost supernatural compared to its rivals. In that moment, amidst the spray and the roar, it was clear: this machine belonged at the front.
Reader's Guide
The FW07B retained the fundamental layout of the original FW07 but featured significant aerodynamic updates designed to reduce drag and improve downforce balance. Patrick Head's team refined the sidepod inlets to optimize airflow to the radiators, a crucial factor in maintaining engine reliability during long stints. Mechanically, the car continued to utilize the ubiquitous Cosworth DFV V8 engine, but Williams' integration of the gearbox and suspension allowed for superior power delivery. The chassis was constructed from aluminum honeycomb monocoque, offering an ideal blend of rigidity and weight savings that became a benchmark for the era. Performance-wise, the FW07B excelled in high-speed corners where its aerodynamic grip shone brightest. It was not necessarily the fastest car in a straight line, but its ability to carry speed through complex sectors made it incredibly difficult to overtake. This balance of speed and reliability allowed Williams to secure consistent podium finishes.
Did You Know?
- Alan Jones won the 1980 World Drivers' Championship with the FW07, not the FW07B, and retired at the end of 1981.
- Williams won the Constructors' Championship in 1981 with the FW07C, not the FW07B.
- Keke Rosberg drove the FW07C at the start of 1982 before it was replaced by the FW08, which was a naturally aspirated Cosworth DFV car—not a turbo—and with which he won the 1982 Drivers' Championship.
- The car's distinctive blue and yellow livery became an iconic symbol of British motorsport success in the 1980s.
Frequently Asked Questions
What is the Williams FW07B?
The FW07B is the 1981 updated version of Williams' successful FW07 chassis, developed under Frank Williams and technical director Patrick Head. It carried the blue-and-yellow livery that became synonymous with the team's rise to F1 dominance.
Who drove the FW07B in Formula 1?
Alan Jones, Carlos Reutemann, and Keke Rosberg all sat in the FW07B cockpit across the 1981 and 1982 seasons. Jones used it to clinch his Drivers' Championship, while Reutemann and Rosberg carried the program into 1982.
What engine powered the FW07B?
It was driven by the Cosworth DFV V8, the naturally aspirated unit that had become a F1 staple by the early 1980s. Pairing that engine with the FW07B's chassis gave Williams a highly competitive package for two consecutive seasons.
What major titles did the FW07B win?
Williams took the 1981 Constructors' Championship with the FW07B, and Alan Jones used the car to secure his 1981 Drivers' title. The chassis remained competitive enough to keep the team at the front through 1982 as well.
How does the FW07B differ from the original FW07?
The FW07B is a refined, mid-cycle evolution of the 1980 FW07 rather than an entirely new design. The 'B' suffix marks the updates that carried Williams' momentum from a strong 1980 into a championship-winning 1981.
