Why Red Bull has challenged FIA's ADUO verdict: 'No data sample shows us ahead of Mercedes'

The handling of Formula 1's first Additional Development and Upgrade Opportunities (ADUO) period, covering the races through the Canadian Grand Prix, continues to dominate discussions in the paddock. The FIA informed all manufacturers of the results in Monaco, but a public announcement is still pending.

This is because Red Bull-Ford is highly dissatisfied with the initial outcome and has asked the FIA to review the decision, arguing that no data sample shows it ahead of Mercedes.
