Purple Bull engine chief Ben Hodgkinson says he “can’t perceive” why a row has damaged out on the eve of the brand new season, describing the wording of laws surrounding F1’s new energy models as “crystal clear”, and insisting “any engineer price their salt” ought to have understood them.
Talking forward of the launch of Purple Bull’s new livery for 2026 at Michigan Central Station (beneath), Detroit, the place engine associate Ford relies, Hodgkinson added there was most likely a “political” facet to the row.

Method One is getting ready for the most important technical shake-up within the sport in a era, with all-new energy models and chassis for 2026. However as is usually the way in which, a livid row has damaged out forward of the brand new marketing campaign, with and understood to have stolen a march on rival energy unit producers because of the exploitation of a “loophole” within the laws.

The particular rule in query, C5.4.3, issues the compression ratio of the cylinders within the new energy models.
New guidelines mandate a most 16:1 ratio, to be measured at “ambient temperature”. Rivals suspect Mercedes and Purple Bull are exploiting thermal growth, decreasing the clearance quantity and successfully rising the compression ratio to one thing nearer to the previous 18:1 restrict.
Whereas it’s unclear how a lot doing so may assist them – estimates vary from wherever as much as 0.4sec per lap, relying on the circuit – it’s clearly sufficient to have rattled Ferrari, Audi and Honda, who’re understood to have written a joint letter to the FIA asking for clarification.
The trio level to a separate standalone sentence within the laws which clearly states: “No cylinder of the engine might have a geometrical compression ratio greater than 16.0.”

Taken at the side of Article C1.5, which states that “Method One vehicles should adjust to these laws of their entirety always throughout a contest”, their argument is that anybody working with a compression ratio above 16:1 when out on circuit is in breach of the principles.
The FIA says it’s reviewing the state of affairs, however has to this point left the principles as they’re.

Hodgkinson, the technical director of Purple Bull’s new Powertrains division, says he can’t perceive why everybody isn’t on the identical web page.
“It’s irritating, actually, some of these items,” he instructed media throughout a convention name on Thursday forward of Purple Bull’s automotive launch. “For me as an engineer, it’s irritating that the press has bought maintain of this. I believe any engineer price their salt that doesn’t perceive about thermal growth doesn’t belong on this sport. Doesn’t should be an engineer, actually.

“Virtually each materials adjustments with temperature. So it’s understanding how supplies behave in several temperatures, pressures, stresses, hundreds. That’s actually our job.
“The laws are tremendous, tremendous clear about compression ratio. You’ve bought a 16 to 1 restrict. The laws say that 16 to 1 is measured in a really particular approach. There’s a doc that describes precisely the way you measure it. And it needs to be measured at ambient temperature. So, it’s tremendous clear.”
Requested why, if it was so clear, different groups had taken a unique view, Hodgkinson added: “Gosh, I believe my actual opinion I most likely can’t say. However I believe there’s various noise within the press about the truth that it’s believed that Mercedes are going to be the benchmark [engine in 2026]. I believe loads of that speak originated from Mercedes themselves. In all probability as a result of the motive force market is de facto powerful, and so they needed to attempt to entice individuals in a automotive that was at present not performing.
“So, it’s important to kind of layer it on the political positioning that everybody has to make. After which, in fact, in the event you say the hearsay sufficient, it begins being believed as a reality, after which individuals begin searching for causes for it. So, I believe that’s a little bit of a idea as to the way it all occurred.

“However there’s an inventory of what you’re allowed to do. So, I don’t actually perceive why everybody’s so up in arms about it.”
Hodgkinson, who spent almost 20 years at Mercedes AMG Excessive Efficiency Powertrains (HPP) earlier than leaving in Might 2022 to affix Purple Bull Powertrains, mentioned he was not sure who would have the very best engine in 2026, however was assured Purple Bull would ultimately be the benchmark.
“I’m assured that the staff I’ve constructed is unimaginable,” he mentioned. “I’m assured the services now we have put collectively are going to be the benchmark. However we’re a newcomer [in terms of power units]. We needed to construct factories whereas individuals began creating their engines. So, I believe we began behind. However I believe the individuals and the services we’ve bought are higher than all people else. So, watch this house. Will now we have overtaken them by race one? I don’t know. We’ll have to attend and see.”
Hodgkinson added that the brand new laws ought to swimsuit the drivers “with essentially the most cognitive bandwidth”, which he famous ought to put Purple Bull in a superb place with four-time world champion on the wheel.

Purple Bull, in the meantime, mentioned RB22’s new livery was “impressed by Purple Bull’s authentic look in F1” and marked a “defining second” for the staff as they made the “daring transfer” into being a PU producer. The 2026 season will even be the staff’s first with out on the helm.

In an announcement, the staff mentioned RB22 “harks again to a extra basic Purple Bull Racing presence, sharpening reflections, boosting distinction below the lights and making heritage components of the brand new livery really feel richer and extra premium at pace”.
Mercedes are launching their automotive on January 22, then Ferrari a day later and McLaren on February 9.
