Williams team principal James Vowles expressed confidence that the team will avoid repeating their 2026 struggles, which included missing pre-season testing, starting 28kg overweight, and taking six months to reach minimum weight. The team introduced a brand-new chassis at the Azerbaijan Grand Prix in late September after falling from fifth to ninth in the constructors' championship.
Vowles credited significant changes to software systems and working methods, along with the arrival of Piers Thynne as chief optimization and planning officer in August. Thynne, son of former Williams commercial director Sheridan, spent nearly two decades at McLaren rising from gearbox specialist to chief operating officer before joining Williams.
The team possesses information they lacked a year ago that allows better decision-making, though Vowles acknowledged uncertainty remains until the first race of 2027. Williams focused their cost cap dollars on elements needed for next year rather than adding aerodynamic performance late in 2026, leaving performance in the wind tunnel at home.
The Azerbaijan upgrade marked forward investment into making the 2027 chassis correct, with much of the work carrying over to next year's car. While the upgrade brought the car to minimum weight with ballast, it arrived too late in the season to add significant aerodynamic improvements for the remaining races.
