The debut of the Red Bull Powertrains-Ford power unit in 2026 is fast approaching. In the days leading up to the high-profile launch, scheduled during the private tests at Montmeló (see the full winter testing calendar), there is no sign of triumphalism. Yet neither are there alarm signals: the words of Mark Rushbrook, the head of motorsport at the Dearborn-based giant, convey an honest vision of the starting point and the real challenges facing the new engine manufacturer. From the outset, Red Bull Powertrains will compete against established giants like Ferrari, Mercedes, and Audi, as well as the future entry of Cadillac.
F1 2026: is Red Bull-Ford slightly behind on the ICE?
Rushbrook does not hide what is seen in Milton Keynes as a natural risk: a potential slight delay on the internal combustion engine (ICE). However, this gap is framed as small and recoverable, especially given the opportunities presented by the new technical regulations.
“It would only be small, I believe. Existing engine manufacturers have all those years of experience advantage, but with these rules for 2026, it’s a bit different. We also have many experienced people coming from other programs. So, if we are slightly behind with the combustion engine, we don’t think it will be by much, and we will catch up,” explained Mark Rushbrook, Global Director of Ford Motorsport, to Autosport.
The key point lies in the regulatory context. The technical cycle that will open in 2026, while complex and heavily regulated, is perceived as less rigid compared to the one that just concluded. It is not a deregulation—the Formula 1 authorities still aim to control potential technical and cost escalations—but it is a framework that offers more room for development and adjustments than the era of near-total freezes that characterized the last few years. In other words, the legislation allows a small margin of flexibility for teams that may start slightly behind, helping them get back on track. The aim is to avoid an “Alpine effect,” reminiscent of the early turbo-hybrid era of F1.
Starting slightly behind doesn’t mean a technical or sporting sentence
In this scenario, starting slightly behind on the ICE does not automatically equate to a technical or sporting setback. The condition, however, is that the gap remains contained and that the team can respond rapidly. This is where Red Bull Powertrains-Ford plays a crucial role, leveraging a mix of expertise from various engine programs and an extremely advanced industrial approach regarding development tools and know-how on the electric component.
Yet the project has not yet faced its true moment of truth: the track. Rushbrook describes this stage with remarkable honesty, acknowledging the tension that accompanies every new engine during its first contact with asphalt.
For now, everything is progressing according to plan within the engine department, but the lack of real-world validation inevitably leaves questions. Less than a month remains until the first collective tests in Barcelona and just a few weeks before the Red Bull and Racing Bulls launch event in Detroit—a symbolic choice that reinforces the partnership with Ford in a city iconic to the brand’s history (see the full presentation calendar).
“We are meeting deadlines where necessary, but everything must fall into place when the car is on track. The first day of testing is important, the first week of testing is important in general; that is when all the work of the past three years starts to pay off. There will always be a certain level of nervousness or anticipation when a new car or a new engine runs on track,” Rushbrook admitted.
The technical challenge: bridging the gap between simulation and reality
The central point from a technical perspective is the gap between simulation and reality. Red Bull Powertrains-Ford has top-level design tools and laboratories capable of covering a huge portion of development work. However, Formula 1—especially when it comes to power units—remains a sport where overall integration can reveal unexpected issues.
“Our tools are excellent for design, as are our laboratories for evaluating and developing the hardware and calibrations. We can simulate a lot. Of course, until everything is together on a real race circuit, you haven’t seen anything. The question is, what will you see on track that you haven’t seen in the lab?” Rushbrook concluded.
This statement perfectly summarizes the mindset of the project: thorough theoretical preparation, strong industrial capability, but also the awareness that the track remains the ultimate judge. In this context, optimism does not stem from the illusion of already being at the level of the best, but from the belief that the 2026 regulations allow credible technical recovery over time and that engineers already know where to intervene if necessary.
If the debut takes place with a reliable power unit and a limited performance deficit on the ICE, Red Bull Powertrains-Ford will be able to play a real game. Not necessarily to dominate immediately, but to grow quickly in a Formula 1 era that will once again reward those who know how to develop, adjust, and respond. For a highly ambitious project built from scratch, this could be exactly the ideal environment.
