Pink Bull is for certain the compression ratio of its 2026 Method 1 engine is inside the laws, as Pink Bull Powertrains director Ben Hodgkinson says the current controversy is “numerous noise about nothing”.
With Pink Bull’s season launch in Detroit, the partnership between Pink Bull Powertrains and Ford is formally being kicked off, though in apply work on the engine undertaking has already been going for 4 years on the Pink Bull Campus in Milton Keynes.
The query stays how aggressive a newcomer will be from the beginning – particularly given the elevated share {of electrical} energy and the relative inexperience of each Pink Bull and Ford on this space, a minimum of in Method 1.
Within the build-up to winter testing in Barcelona, nevertheless, a lot of the consideration has targeted on the interior combustion engine, and extra particularly on the compression ratio. It’s the ratio between the most important and smallest quantity within the cylinder. Below the earlier set of laws that ratio was nonetheless 18:1, however for 2026 it has been lowered to 16:1 – amongst different causes to make the foundations extra accessible for newcomers.
Different producers have develop into conscious that Mercedes and Pink Bull Powertrains would adjust to the 16:1 restrict throughout static assessments at ambient temperature – which, because it stands, is the one means the FIA checks it – however that they might obtain a better ratio whereas operating at increased temperatures.
Audi, Ferrari and Honda have collectively raised the problem with the FIA, after which it has been positioned on the agenda for a gathering with technical consultants on 22 January – which covers a number of matters, together with the aero facet of the brand new ruleset.

Forward of the season launch, Pink Bull Powertrains director Ben Hodgkinson advised a choose group of media, together with Motorsport.com, that he’s satisfied Pink Bull’s new energy unit is inside the laws.
“I feel there’s some nervousness from numerous energy unit producers that there is perhaps some intelligent engineering happening in some groups,” he mentioned. “I am not fairly positive how a lot of it to hearken to, to be trustworthy. I have been doing this a really very long time and it is virtually simply noise. You simply must play your individual race actually.
“I do know what we’re doing, and I am assured that what we’re doing is authorized. After all, we have taken it proper to the very restrict of what the laws enable. I might be shocked if everybody hasn’t accomplished that. My trustworthy feeling is that it is numerous noise about nothing. I anticipate everybody’s going to be sitting at 16, that is what I actually anticipate.”
The crux of the matter is that completely different PU producers discuss with completely different elements of the technical laws. Article C5.4.3 states that checks are carried out solely when the engine is stationary and at ambient temperature, which means Mercedes and Pink Bull can argue that they’re working inside these boundaries.
Rivals, nevertheless, level to Article C1.5, which states that “Method 1 Automobiles should adjust to these laws of their entirety always throughout a contest.” As a result of the 16:1 compression ratio is explicitly talked about, they imagine this also needs to apply whereas operating.
Usually phrases, Hodgkinson just isn’t impressed by the compression ratio as it’s included within the new PU guidelines. In his view, scaling it again for 2026 was a very pointless step.
“From a purely technical viewpoint the compression ratio restrict is just too low,” he defined. “Now we have the know-how to make the combustion quick sufficient, so the compression ratio is means too low. We may make 18:1 work with the velocity of combustion that we have managed to get, which suggests there’s efficiency in each tenth of a ratio that you would be able to get. Each producer ought to actually be aiming at 15.999 so far as they dare when it is measured.”
