Ford has delivered a carefully worded reality check on Red Bull’s all-new 2026 Formula 1 power unit, admitting that while development targets have been achieved on paper, the project’s biggest test is still to come.
Ford Hints Red Bull’s New Engine May Reveal Surprises Once It Hits the Track
Red Bull Ford Powertrains will enter a new era in 2026 as Formula 1 introduces sweeping power unit regulation changes, including increased electrical deployment and revised combustion rules. Despite extensive development work, Ford Performance Director Mark Rushbrook acknowledged that uncertainty remains inevitable until real-world data can replace simulations.
Talking to the media, Rushbrook said, “We are to plan, so where we need to be, but it all comes together when it’s actually in the car and on track. So that first day of testing is an important date, and an important week. It’s when we get to see how all this hard work in the past three years is going to pay off.”
Rushbrook’s comments highlight the key challenge facing Red Bull’s first in-house engine programme and the struggles of translating lab performance into competitive lap times. While Ford and Red Bull have leaned heavily on advanced simulation tools, dyno testing, and calibration software, Rushbrook emphasized that no level of development environment can exactly replicate race-track conditions.
“There’s always some level of nervousness or anticipation anytime there’s a new car or engine on track,” he said. “Our computer tools are great for designing; our labs are great for evaluating and developing the hardware, and the calibration that goes with it, so we can simulate a lot.”
He added, “But until you get it all together on an actual race track, you haven’t seen everything. And it’s a question of what are you going to see on track that you didn’t see in the lab.”

That unpredictability, according to Rushbrook, is where new manufacturers like Ford are most vulnerable. Even the most minor, unforeseen issue, such as thermal behavior, energy deployment efficiency, drivability, or integration with the chassis, can expose weaknesses that never appeared in any of the numerous testing sessions.
Despite those concerns, Rushbrook confirmed that Red Bull Ford Powertrains has met its internal objectives under the 2026 regulations, and if any performance gaps did crop up, they would be marginal. “But it would only be slight, I think. Because yes, existing engine manufacturers have all those years of experience, but it’s still a bit different again with these rules for 2026,” he explained.
Although Ford’s remarks stop short of raising alarms, they did subtly highlight Red Bull’s biggest unknown heading into the new F1 era. Now, only time will tell whether Red Bull’s bold step into engine independence delivers immediate success or exposes early growing pains.
