On the Tuesday earlier than Silverstone’s British Grand Prix at Silverstone, a handful of media are welcomed into the Jochen Rindt constructing. It’s the location on the Purple Bull Campus in Milton Keynes the place Purple Bull Powertrains and Ford are working away with lots of of staff on Purple Bull’s personal engine undertaking for 2026.
That 12 months, each the engine and chassis laws will endure a significant overhaul in F1. On the engine aspect, the MGU-H will disappear, however the proportion of electrical energy will go up significantly to an nearly fifty-fifty break up with the inner combustion engine. The V6 has to run on sustainable fuels.

Simply as massive a change for Red Bull is that Honda leaves as its engine associate that 12 months. Presently, all Red Bull Racing and RB engines are nonetheless produced in Japan. However as Honda will be part of forces with Aston Martin, Purple Bull has taken its destiny into its personal fingers by creating its personal engines, for the primary time in its 20-year existence.
Because the vitality drinks big faces its largest problem to this point, Purple Bull Powertrains is providing a uncommon look behind doorways which might be usually closed.
The day begins with a reception in MK7, the constructing the place many Purple Bull automobiles from earlier F1 seasons are on show. After that it’s time to head over to the Purple Bull Powertrains facility, the place Christian Horner and Ford Motorsports chief Mark Rushbrook clarify that work on the constructing began early 2022.
Work on the ICE part (inner combustion engine) started first, adopted by the ERS division early this 12 months, coping with {the electrical} elements of the engine that can turn into much more vital underneath the 2026 laws.
After we’re instructed that it’s strictly forbidden to take images – with work in full swing – we stroll in the direction of ‘Brodie’s Boulevard’.Â
This hallway is called after Steve Brodie, one of many first staff to return over from Mercedes HPP in August 2021, who performed an vital position in organising the Powertrains facility. His official title is ‘Head of Energy Unit Operations’, which suggests Brodie is answerable for the ICE and ERS construct outlets to ensure Purple Bull-Ford construct it to the right specs, requirements and consistency.

One of many engines may be seen instantly upon getting into.
“This was the very first combustion engine we made,” Horner explains. “The hearth-up of this V6 was in August 2022. Dietrich Mateschitz was in a position to hear this primary ever Purple Bull engine simply earlier than he handed away. After his loss of life, we determined to label all our engines as DM, so Dietrich will at all times be on the coronary heart of Purple Bull automobiles.”
Horner provides that after preliminary talks, the engine on show additionally performed a task in convincing Ford to hitch the undertaking when negotiations between Purple Bull and Porsche broke down.
Rushbrook explains: “When it grew to become clear that it would not work for Purple Bull with Porsche, I actually acquired Christian Horner’s e mail tackle, despatched him an e mail and requested ‘hey, possibly you need to speak to us?'”
It has led to the present partnership, which is completely different from the sooner plans with Porsche. Ford doesn’t demand a say within the F1 staff itself to the extent that Porsche did.
“We aren’t saying ‘you need to do it like this’. No, Purple Bull has been in Method 1 for years, so we primarily ask them what they want from us to achieve success collectively,” provides Rushbrook.
“Primarily based on our preliminary discussions, we have been solely going to contribute to {the electrical} elements of the 2026 engine, however now we’re additionally contributing to the turbocharger and testing rigs for the combustion engine, additionally as a result of Ford already had data or tools for that.”
Brodie’s Boulevard results in the engine retailer, the place numerous engine elements are sorted. From there, it goes to the cleansing space after which to the construct store, the place the inner combustion engines are assembled. As every little thing needs to be spotless and exact, this meeting space seems to be extra like a laboratory than a daily workshop. One half is for a V6 engine, the opposite for a single cylinder, which is used to make improvement extra environment friendly.

“I am clearly a bit biased, however the set-up now we have right here seems to be much more state-of-the-art than what Mercedes has,” Brodie smiles. “But it surely needs to be, as I had lots of freedom to provide you with this set-up myself.”
On the subject of testing, Brodie fingers over to Florian Niehaves. The German engineer beforehand labored at AVL, the place Purple Bull additionally purchased gear for the engine facility, and now works instantly for the Powertrains undertaking.
He leads us into the following room, which is considerably harking back to mission management for area missions. That is the hub for a number of testing rigs of particular person engine elements earlier than they go onto the total energy unit.
Producers should adjust to strict testing guidelines in Method 1. Every engine facility is simply allowed to have three take a look at benches for a full energy unit, three for a single cylinder and two for the ERS. Purple Bull Powertrains signifies that it’s near the restrict of what’s allowed when it comes to tools.Â
With the infrastructure at the moment in place within the Jochen Rindt constructing, Purple Bull Powertrains says it could actually provide a complete of 4 F1 groups with engines. It implies that subsequent to Purple Bull Racing and the RB staff, there’s room for 2 extra buyer groups, though that’s not the plan for 2026.
“Now we have been approached by completely different groups, some are probing to see who can have essentially the most aggressive engine,” Horner explains. “However our focus is totally on the 2 Purple Bull groups in the meanwhile, as a result of we need to stroll earlier than we run. If one thing would possibly come up later, then we’re open to the proper associate.”
Horner provides that the monetary guidelines for engine provides additionally want altering “as a result of supplying an engine to a buyer is a loss making train based mostly on the FIA pricing”.
“I now nearly have sympathy for Cyril”, he jokes, referring to former Renault F1 chief Cyril Abiteboul with whom he entertained a frosty relationship.

After the meeting and take a look at areas, the tour is nearly over, however Horner says: “This was not on the preliminary programme, however let’s take a look on the design places of work as properly.” Taking images is as soon as once more strictly forbidden, because the screens are filled with figures and design sketches which might be far too difficult for the standard journalists attending, however can be of curiosity to rivals.
The Purple Bull Campus has grown significantly for the reason that Jaguar staff was acquired in 2005, with a complete of 1,800 staff working there immediately. The journey has required an increasing number of buildings in Milton Keynes and the in-house engine undertaking needs to be the most recent step.
After frustrations with Renault’s efficiency and Honda’s resolution to give up, Purple Bull is banking on this undertaking to combine the engine and chassis even higher and, above all, to not be depending on an engine provider.
“We take destiny totally into our personal fingers now; other than Ferrari, we’re the one staff in F1 to have the engine and chassis departments on the identical campus heading into 2026. Even Mercedes has two completely different places,” Horner refers to Brackley and Brixworth. “It could appear an unimaginable job, however we expect it has long-term advantages.”
Extra vital is simply how aggressive the engine will probably be, however that may be a query nobody can reply – not in Milton Keynes, nor at another producer.
“We’re at the moment assembly all our personal targets and milestones, however we don’t know the place the opposition stands,” says Rushbrook. “Our motto needs to be: under-promise and over-deliver.”
