David Coulthard warns "heads will roll" if Williams FW48 upgrade fails

David Coulthard has issued a stark warning regarding the Williams FW48 upgrade, stating that significant consequences could follow if it fails to improve the team's performance. The Grove-based team has struggled throughout the season, currently sitting ninth in the constructors' championship with only 11 points, largely due to the car's overweight issues.

The upgrade, described by team principal James Vowles as nearly a B-spec car, is aimed at enhancing performance at the Azerbaijan Grand Prix. Coulthard, drawing comparisons to Aston Martin's previous upgrades, believes that the changes should yield a notable improvement. However, he cautioned that if the expected results do not materialise, there could be serious repercussions for the team.
