Williams completed a double constructors' coronation at Spa: 368 points secured the Season 5 D1 title by 56 over Ferrari, while 330 took D2 by 64 over Haas.
FatCatBatMan465 won the D1 finale from third for Williams, with UKTUS second for Alpine and Techubi third for McLaren. The chequered flag gave the first of those team titles a matching race result.
D1 splits the drivers' and constructors' crowns
Sammy278 finished D1 drivers' champion on 190 points for Ferrari, 14 ahead of FatCat. Williams therefore took the team title while Ferrari supplied the individual champion—a clean division of Spa's two season honours.
One badge, two constructors' trophies
The D2 table added the second half of Williams' double. Its 330 points beat Haas on 266, making the final margin eight points larger than the 56 separating Williams and Ferrari in D1.
Neither championship was a decorative first-place label. Spa closed both calendars, removed the remaining scoring ceiling and converted the two leading totals into titles.
Season 5 ended with Williams owning two of the six constructors' crowns, earned through different division campaigns but confirmed on the same final weekend.
