Red Bull RB22 weight loss could unlock key Verstappen and Hadjar gains

Red Bull’s RB22 still fighting a significant weight penalty

Red Bull’s 2026 Formula 1 car remains caught in one of the defining technical battles of the new rules cycle: weight. The issue affecting the 2026 grid has been clear since pre-season testing, driven primarily by the need to retain, or even slightly increase, battery dimensions and volume compared with 2025 as the electric-power contribution has grown.

Among the cars understood to have suffered most heavily is the Red Bull RB22. At the start of the season, it was reported to be more than 10kg above the minimum weight, with estimates around 13kg overweight during the Barcelona shakedown and Bahrain tests.

Updates aimed at more than aerodynamics

The latest understanding is that the RB22s of Max Verstappen and Isack Hadjar are now around 6-8kg overweight. That remains a significant margin in Formula 1 terms, but it also suggests progress has been made from the car’s earliest specification.

Red Bull’s next step is expected to centre on a further underbody evolution, alongside redesigned components that would allow thinner materials to be used than those initially adopted. That direction fits naturally with the team’s broader upgrade push, which has already placed the RB22 under close scrutiny; for more context, see our analysis of Red Bull’s Austria upgrade and why it may not be enough.

Why weight loss could change the car’s behaviour

The implications go beyond a simple lap-time gain from carrying less mass. Weight reduction has a direct impact on vehicle dynamics, and Red Bull’s engineers believe that trimming the excess could also ease problems linked to the car’s dynamic response.

In practical terms, a lighter RB22 may allow setup options that were previously unworkable, particularly if the car’s weight distribution changes as part of the process. That means some dynamic limitations could potentially be reduced without requiring additional changes such as suspension revisions.

For Verstappen and Hadjar, the most important benefit may come through tyre utilisation. A better-balanced car, with less excessive weight transfer, should give the drivers a stronger platform from which to manage performance across a stint.

Energy management is another direct consequence. A lighter car requires less energy on the straights and should make it easier to maintain energy balance across a lap — a simple principle, but one with potentially significant competitive value for Red Bull’s 2026 recovery.
