Method 1 is looking for its id: the brand new rules are nonetheless unclear, although engine producers have been engaged on the 2026 energy models for no less than 4 years, investing closely. But it surely’s not simply the producers (Mercedes, Ferrari, Honda, Audi, Crimson Bull Powertrains) engaged within the analysis—suppliers are additionally working silently, with out visibility, on modern options, driving supplies analysis that might remodel merchandise and contribute to efficiency features.
Whereas discussions proceed over how energy needs to be divided (rumors recommend 50% electrical and 50% inner combustion in qualifying, however 150 kW can be faraway from the electrical aspect throughout races to keep away from charging points at circuits with decrease power restoration like Monza, Jeddah, Las Vegas, and Baku), some are already deeply concerned in defining options that might want to work whatever the closing guidelines accredited…
Because of its experience, UFI Filters has earned the belief of all ten groups at the moment on the F1 grid: the Verona-based firm provides every workforce with round a dozen filters (starting from 11 to 17), every of which is “tailor made” via co-design with the groups, making each factor distinctive.
The 2026 rules elevate the technological problem with more and more excessive fields of analysis. UFI Filters will intervene on a number of elements of F1 automobiles: engine oil, engine air filter, and hydraulic circuits that management DRS, energy steering, and brakes, the place filtration is crucial to make sure driver security. There are additionally filters for dielectric fluids utilized in thermal administration of the battery and hybrid system temperatures.
In brief, the scope of motion may be very large, and it’s attention-grabbing to find what is going to change for UFI Filters with the brand new energy models and the introduction of e-fuels…
“Within the inner combustion engine, we assist optimize efficiency,” explains Davide Moletta, Excessive Tech Division Supervisor at UFI Filters. “At this stage, speaking about 100% artificial gas is extra of a advertising and marketing operation. From 2026 to 2030, fuels will comprise solely 20% ethanol and can nonetheless be petroleum-derived. The true shift to artificial will are available 2030, when ARAMCO will launch the bottom recipe to different producers. It gained’t be a single-spec gas, however fairly a base chemical components launched by ARAMCO, the Saudi firm working with the FIA. Then, producers will be capable of customise their fuels in response to their wants: detonation, combustion sort, and timing.”
Are paddock rumors true that the perfect gas may supply a 30-horsepower benefit?
“Within the high-pressure gas circuit, not one of the producers have reached the five hundred bar restrict allowed by the principles. Some have pushed to 300–320 bar, however that’s already a threshold the place issues begin. Inside a fluid, which consists of assorted chemical components, it’s important to management the strain and temperatures. Past a sure level, chemical reactions can ignite, resulting in fluid acidification or NOx emissions within the exhaust.”
“The engine is sort of a violin that wants tuning,” provides UFI Filters president Giorgio Girondi. “Some handle it properly, others much less so. We use metal for the filtering half and titanium for the metallic parts. Their traits be sure that even with full filter blockage on the circuit’s most upstream pump strain, there isn’t any leakage. Our filter gained’t collapse or explode, so the automotive stops, however the engine isn’t compromised. You simply want to exchange the filter, and the automotive can restart…”
Are you testing modern options by no means utilized in F1 for subsequent 12 months?
“With filtering media,” continues Davide Moletta, “we always obtain up to date formulation from groups: we’re speaking about fiberglass as a substitute of polypropylene. As soon as a polymer is chosen, we instantly perform buyer testing with 20% ethanol gas. We do the identical with adhesives. Updates are almost every day, making dimensional research extra agile. Air filters, for instance, are available very totally different shapes due to every workforce’s aerodynamic design. Each engine maker defines a selected house: filtration is likely to be comparable, however sizes are very totally different.”
What’s essentially the most crucial factor?
“The filter that protects the motive force. We will afford an engine challenge that stops the automotive, however not a failure in driver security: the DRS and brake circuits should all the time be good. For the hydraulic circuits, we collaborate with Brembo: security is paramount, in order that a part of the circuits is certainly essentially the most difficult.”
Will there be adjustments on this space in 2026?
“The assorted hydraulic manifolds have particular technical filtration necessities. In braking, there’s now a twin rear circuit—the place as soon as the pedal immediately managed the caliper, at the moment there’s brake-by-wire, which provides power restoration braking: two hydraulic circuits, another conventional and a second multi-pass. The 2 techniques require totally different filters. The primary lasts longer, whereas the second is far more high-performance.”
The 2026 improvements gained’t cease on the energy models—there will even be lively aerodynamics on the entrance, along with the rear DRS flap. This gained’t essentially enhance the variety of filters on the automobiles. It’ll rely on the hydraulic circuit configuration developed by groups and the necessities of the hydraulic manifolds, the management models that regulate fluid circulation. To keep away from points with the valves that open and shut the circuits (and thus, the moveable wings), the oil inside have to be extraordinarily clear. For reference, the baseline filtration requirement is 3 microns—this is applicable to the braking system too.
The workforce of technicians led by Davide Moletta and devoted to F1 consists of about fifteen specialists working from the Nogarole Rocca headquarters. However the Verona multinational additionally depends on three R&D facilities in Ala di Trento, Shanghai, and New Delhi…
“We contain engineers in India for fluid dynamics and mechanical analyses, boosting our work energy with 40–50 native technicians. On the subject of designing with metallic or plastic filter supplies, the Nogarole Rocca workers collaborates with the Ala di Trento workforce.”
UFI Filters believes within the two-way change of technical information between the automotive and motorsport worlds…
“We’re pushed by ardour and love tackling the hardest analysis,” says Girondi. “We’re learning filtration for hydrogen, which will likely be essential for future e-fuels.”
Are you exploring new supplies?
“There are numerous attention-grabbing options for filtering media,” concludes Moletta. “With 3D-printed supplies loaded with carbon and Kevlar, we’re years forward of present necessities. You should by no means cease. And F1 pushes us to all the time go additional.”
One instance is the try to scale back the burden of 2026 automobiles by about thirty kilos: weight discount, past dimensional research, will contain refining each single part. Crew chief designers are evaluating transferring hydraulic circuits and filters to extra advantageous positions for automotive steadiness.
“Normally, the shopper drives the event of the hydraulic circuit to optimize the scale of the filter housings. As soon as the best spot is discovered to benefit from out there house and optimize weight distribution,” concludes Davide Moletta, “UFI receives weight targets. To satisfy them, we work on filtering media and more and more thinner aluminum partitions.”
