Williams will introduce an almost entirely new car by the Formula 1 Azerbaijan Grand Prix in late September. The team will roll out a medium-sized upgrade package at this weekend's British GP, followed by smaller updates at subsequent races.
Williams team principal James Vowles confirmed the timeline while speaking to Sky Germany. He outlined a sequence of developments starting with Silverstone and continuing through Spa, Budapest and Zandvoort before the major package arrives in Baku.
The Grove-based squad currently sits eighth in the constructors' standings with 11 points. It has scored no points in the last two races and delivered no upgrades in Austria.
Alex Albon said the British GP updates would not reach the midfield but could bring the team closer to Haas. He noted that Williams was lapped by Racing Bulls in Austria.
