While the FIA will discuss Formula 1\u2019s ongoing compression ratio controversy<\/a> with manufacturers at an engine meeting later this week<\/a>, even those pushing for a change to the rules are not anticipating much movement.<\/p>\n

The FIA\u2019s gathering that takes place on Thursday will include engine technical experts and is aimed at addressing concerns that have been lodged by Ferrari, Audi and Honda about a potential exploitation of F1\u2019s compression ratio limit.<\/p>\n

The three manufacturers are unhappy that Mercedes and Red Bull may have found a way to run their engines at a higher compression ratio<\/a> \u2013 which brings added performance \u2013 than the 16:1 ceiling that is theoretically laid down in the rules.<\/p>\n

But with the FIA appearing to have initially backed the views of Mercedes and Red Bull (that compliance of the 16:1 limit is based on measurements taken at ambient temperatures), there has been little expectation from outside of anything changing in the short term.<\/p>\n

One manufacturer source who has good knowledge of the discussions taking place behind closed doors suggests that the best hope realistically is for the FIA to lay down firmer guidelines to put everyone on the same page for 2027.<\/p>\n

However, it is understood that the FIA does not want the issue to drag on into 2027 so is evaluating a potential response that could come in to play for this year.<\/p>\n

FIA single seater director Nicolas Tombazis seemed to hint on Wednesday that something could be changed as soon as this season.<\/p>\n

“When we have new regulations, I think it is normal that there will be some discussion points, some areas which need a bit of clarification or adjustment, and that’s what we are currently discussing with the various stakeholders,” he told The Times.<\/p>\n

“We have an objective to make sure that procedures are interpreted and understood in the same way.<\/p>\n

“We are confident the rules can be clarified and I would say that I’m sure it will no longer be a talking point very soon.”<\/p>\n

Quite what this response would be is unclear, but discussions on the topic will certainly advance on Thursday.<\/p>\n

A move to get something in place for 2026 would be a welcome move for rivals like Audi F1 project leader Mattia Binotto, who has said ahead of the meeting that he only expects things to change over the long term.<\/p>\n

\u201cIt’s simply we are trying, all together, to really develop a methodology where we can measure it in real time while the car is running,\u201d he said.<\/p>\n

\u201cMy hope in that meeting is not clarity on the regulation itself, but more to define a methodology for the future.\u201d<\/p>\n

The choice then will be whether those manufacturers who are not happy decide to challenge things with race stewards at an event, potentially through a formal protest, or simply accept they have missed a trick and set about trying to pursue that route as quickly as possible.<\/p>\n

That latter option appears to offer the line of least resistance and would avoid a flashpoint controversy, especially with F1\u2019s 2026 rules offering potential for those manufacturers who are on the backfoot to be given additional development opportunities in-season.<\/p>\n

A matter of time<\/p>\n

While some paddock insiders have suggested that F1\u2019s additional development and upgrade opportunities (a system known as ADUO) are so generous that they could allow a struggling manufacturer to leapfrog their way to the front, not everyone agrees with that.<\/p>\n

In fact, Red Bull Powertrains\u2019 technical director Ben Hodgkinson reckons that the rules do not really fit in with the reality of just how difficult and time-consuming it is for engine manufacturers to make design improvements.<\/p>\n

\u201cThe bit that I don\u2019t think is fully understood amongst the rulemakers is that the gestation time of an idea in power units is much longer than it is for the chassis,\u201d he said.<\/p>\n

\u201cSo if I need to make a change, firstly, I\u2019ve not just got two cars to update, I\u2019ve got a whole fleet of engines in the pool. So I could have 12 engines that I need to update. That takes time.<\/p>\n

\u201cBut also, because we\u2019re homologated, you can\u2019t really take a flyer on something that isn\u2019t well proven, because you could be signing up to a world of pain.\u201d<\/p>\n

Hodgkinson thinks it can take up to 12 weeks to produce the right high-precision internal components, that time again to check their durability on the dyno, and then a further 12 weeks to bring new units to the race pool.<\/p>\n

So even if Audi, Honda and Ferrari all knew exactly what Mercedes and Red Bull were doing (which it is understood they don\u2019t), and were ready to revamp their engines right now, it could take six months to bring new designs through.<\/p>\n

This is why Hodgkinson believes that any advantage locked in at the start of this season by a manufacturer will stay intact for quite a while.<\/p>\n

\u201cI think that if a team has an advantage on the power unit in race one, it\u2019s going to take some time before anyone else can catch up,\u201d he said.<\/p>\n

\u201cSo a way to peg them back is kind of what\u2019s necessary, which the ADUO does offer in some respects.<\/p>\n

\u201cAfter six races it\u2019s assessed, so technically at the seventh, you can introduce the update. But I think that it\u2019s quite challenging to come up with an update in a couple of weeks.\u201d<\/p>\n

The cost factor<\/p>\n

Even a late-season effort to bring a newly homologated engine \u2013 should a manufacturer get permission under ADUO \u2013 will bring complications in terms of how a supposedly better power unit\u00a0gets slotted into a race pool.<\/p>\n

F1\u2019s 2026 regulations limit drivers to four internal combustion engines for the entire campaign \u2013 and they likely will have cycled through most of those by the latter part of the season.<\/p>\n

And while having a much better engine specification on tap would be grounds to swallow a grid penalty, changes to the cost cap rules mean there will be a downside to doing that now.<\/p>\n

Last year, as Red Bull showed when it gave Max Verstappen a fresh engine<\/a> in Brazil for performance reasons, the switch was pretty straightforward to bring in as it fell outside the cost cap.<\/p>\n

For 2026, the arrival of financial restrictions for manufacturers means that there is now a huge disincentive for extra engines to be brought into the pool if not done on reliability grounds.<\/p>\n

Additional supply costs borne by manufacturers bringing in engines that are just for added performance will come directly out of their budget cap \u2013 so they would impact spending on further developments.<\/p>\n

It is yet another reason to think that any major reset in terms of the divided approach to engine combustion across all manufacturers will not come until 2027.<\/p>\n

Key area<\/p>\n

The situation surrounding potential to be unlocked from the ICE is why many senior figures think this area will be a key performance differentiator early on.<\/p>\n

\u201cThe ERS [Energy Recovery System] side, I think everyone will be 99% efficient on their power electronics and motor,\u201d Hodgkinson said.<\/p>\n

\u201cThe best [combustion] engines last season were around 50% [efficiency], so there is still quite a lot to go at.”<\/p>\n

Haas technical director Andrea De Zordo believes that those missing out on power could find themselves facing an uphill battle.<\/p>\n

\u201cInitially with the PU, as it\u2019s all so new, there is – not necessarily more to gain, but a lot more to lose if you don\u2019t do well,\u201d he explained earlier this week.<\/p>\n

\u201cTo understand how it works and how to maximize that will probably be the most important part.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"While the FIA will discuss Formula 1\u2019s ongoing compression ratio controversy with manufacturers at an engine meeting later…\n","protected":false},"author":2,"featured_media":428022,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[572],"tags":[64,63,806,805,803,804,85],"class_list":{"0":"post-428021","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-motosport","8":"tag-au","9":"tag-australia","10":"tag-motor","11":"tag-motor-sports","12":"tag-motosport","13":"tag-motosports","14":"tag-sports"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/428021","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=428021"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/428021\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/428022"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=428021"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=428021"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=428021"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
