Red Bull is now openly being tied to Formula 1's most drastic engineering option: starting over. F1 Insider's Ralph Buch, reporting on internal conversations at the Milton Keynes outfit, claims the team is considering abandoning its 2026 car concept entirely and developing a full B-spec replacement mid-season — a step Christian Horner's team has not had to contemplate in the Verstappen era.
Buch's assessment of the mood inside the team is blunt: the view is that the current car is so fundamentally off the pace that incremental upgrades will not save the season, and that engineers may need to tear up the concept and restart. That is the argument being made for a full B-spec car — not a floor tweak, not a sidepod revision, but a genuinely new chassis philosophy wearing the same livery.
The data backing that conversation came from Suzuka, where Red Bull brought its first significant 2026 upgrade package. Only Verstappen's car received the full specification, including new sidepod geometry and floor changes. In the cockpit, the reigning champion was unconvinced. Verstappen felt the upgrade had, if anything, made the car worse — a damning verdict on a package the team has been building towards all winter.
The wider context is not helping. The 2026 regulations have produced a field in which qualifying pace and race pace are increasingly decoupled, and where energy deployment strategy determines as much of the lap time as aerodynamic downforce. Damon Hill, covering the Japanese Grand Prix, captured the problem visually during one of the closing-speed incidents: it was, he said, basically like getting brake-tested — describing what was happening to cars emerging from boost mode behind drivers in energy-saving mode.
In that environment, a car that is slightly off in multiple areas can look catastrophic on television. Red Bull's 2026 chassis has been described by both Verstappen and rookie teammate Isack Hadjar in strongly critical terms over recent weekends, and the in-race evidence has been consistent — the car is not behaving as a Red Bull is expected to behave.
A full B-spec would be a huge undertaking. It would consume most of the remaining budget cap headroom, require wind-tunnel and CFD programmes to be restarted on new reference geometry, and functionally cost the team the rest of the current season while it is built. There is an argument that 2026 is already unwinnable in the drivers' championship and that protecting 2027 is the more valuable play — but pulling the trigger on a wholesale rebuild is still a decision no Red Bull leadership has had to publicly justify in a decade.
It also has to be weighed against the Verstappen situation. With the Dutchman openly admitting he is considering his F1 future and a performance-linked exit clause reportedly in the contract, Red Bull is being pushed into a binary choice: go for a desperate, expensive overhaul and try to stop the slide, or accept the season and risk handing Verstappen the trigger he needs to walk. The B-spec conversation is not really about a car. It is about whether Red Bull still believes it can make 2026 competitive in the time available.
