Red Bull’s 2026 Gamble: Horner Faces F1’s Biggest Reset

Christian Horner is leading Red Bull into F1’s biggest transformation yet, with a bold move to develop an in-house engine for 2026.

Red Bull isn’t off to a strong start in 2025, with the RB21 struggling to deliver the expected performance. But that’s not the only challenge the team is facing.

Team principal Christian Horner admits he’s already deeply immersed in preparations for 2026. Beyond designing an entirely new chassis, Red Bull is also working on its first in-house engine, developed under the Red Bull Powertrains banner in collaboration with Ford for the hybrid components.

“For me, this new chapter is incredibly exciting. It’s by far our biggest challenge yet, and it’s not for the faint-hearted. It’s going to be an epic journey, one that I’m looking forward to and truly enjoying.”

Red Bull’s Bold Gamble: Building Their Own Engine

Over the years, Red Bull has seen massive success designing its own chassis while partnering with different engine suppliers, from Renault to, more recently, Honda. But with the new 2026 engine regulations, the team felt it was the right time to take full control of its destiny.

“It’s a race against time because, this time next year, these engines will be running in our Grand Prix cars.”

This shift is monumental. In 2026, Formula 1 cars will be 30 kg lighter, 10 cm narrower, run on fully sustainable fuels, and feature a 50-50 hybrid-electric and combustion engine setup. Red Bull must adapt to all these changes in one go—a major technical challenge.

A Steep Learning Curve Ahead

Horner remains realistic about the uphill battle Red Bull faces against established engine manufacturers.

“The challenge is massive, and it would be naive to think we’ll instantly outperform rivals who have been both constructors and engine suppliers for years.”

However, this long-term commitment is about securing Red Bull’s future in F1. By producing its own power unit, the team ensures it won’t be dependent on external manufacturers, safeguarding its independence even if another engine supplier exits the sport.

“The 2026 regulations are a complete reset. Forget everything you knew before—this is a clean slate. Nothing carries over.”

With the clock ticking, Red Bull is racing against time to be ready for the first Grand Prix of 2026. But with a strong team, world-class facilities, and a winning culture, Horner is confident they’ll rise to the occasion.

“This is the ultimate race against time. We have incredible people, an amazing culture, and top-tier facilities. Now, it’s about pushing to be ready for that first race in 2026.”
