Before a wheel has turned in anger, there are fears that Mercedes \u2013 who also provide engines to defending champions McLaren, Williams and Alpine \u2013 and <a href=\"https:\/\/www.theguardian.com\/sport\/red-bull\" data-link-name=\"in body link\" data-component=\"auto-linked-tag\" rel=\"nofollow noopener\" target=\"_blank\">Red Bull<\/a> have gained a vital advantage.<\/p>\n<p class=\"dcr-130mj7b\">The new generation of hybrid engines are likely to be the key to performance in 2026 and a dispute over how Mercedes, Red Bull, Honda \u2013 who are supplying Aston Martin \u2013 Ferrari and Audi have built their new units has been growing during the close season. There is mounting apprehension that Mercedes and Red Bull may have found a way to gain as much as between 0.3 and 0.4 seconds of a lap \u2013 a huge advantage in F1 terms \u2013 over their competitors.<\/p>\n<p class=\"dcr-130mj7b\">The technical gain is centred around engine compression ratios, the difference between the maximum and minimum volume of the cylinder during the piston stroke. This season it is set at 16:1, measured at an ambient temperature when the car is at rest, but other manufacturers believe Mercedes and Red Bull have used materials that give them an edge. When running on a track, they take advantage of the thermal expansion of components to increase the compression ratio and an engine\u2019s power but adhere to the rules when not running.<\/p>\n<p class=\"dcr-130mj7b\">It is understood that Ferrari, Audi and Honda were so alarmed that they have written to the FIA and their concerns will now be aired at the meeting.<\/p>\n<p>Honda\u2019s Toshihiro Mibe (right) shares his thoughts with Aston Martin\u2019s Lawrence Stroll at the Japanese manufacturer\u2019s F1 launch in Tokyo.  Photograph: Takashi Aoyama\/Getty Images<\/p>\n<p class=\"dcr-130mj7b\">Red Bull are developing their own engines for the first time and their technical director, Ben Hodgkinson, who worked on Mercedes\u2019 engines for 20 years, was bullish that all their works was entirely within the rules. If their rivals had missed a trick, it was their failing not Red Bull\u2019s.<\/p>\n<p class=\"dcr-130mj7b\">\u201cI know what we\u2019re doing. I\u2019m confident that what we\u2019re doing is legal,\u201d he said. \u201cOf course, we\u2019ve taken it right to the very limit of what the regulations allow. I\u2019d be surprised if everyone hasn\u2019t done that.<\/p>\n<p class=\"dcr-130mj7b\">\u201cAny engineer that doesn\u2019t understand about thermal expansion doesn\u2019t belong in this sport, doesn\u2019t deserve to be an engineer really. Understanding how materials behave in different temperatures, pressures, stresses, loads \u2013 that\u2019s literally our job.\u201d<\/p>\n<p class=\"dcr-130mj7b\">That this was no small matter was emphasised by Honda as they launched their new engine. \u201cRegulations do not have everything listed very clearly, bit by bit,\u201d said their chief executive Toshihiro Mibe. \u201cThere is a lot of room for interpretation as well and this is a part of the race. So for the FIA, it\u2019s up to them to decide on whether it\u2019s good or bad. For Honda, we have a lot of different ideas, and we would like to discuss with the FIA to understand if our ideas are accepted or are not OK.\u201d<\/p>\n<p>Audi launch their new F1 car in Dresden but behind the scenes the German team are troubled by rivals\u2019 interpretation of new engine regulations.

Koji Watanabe, president of Honda Racing Corporation, warned that the regulations were challenging and that \u201cperhaps we will struggle\u201d.<\/p>\n<p class=\"dcr-130mj7b\">All of which will concern Aston Martin, and at Ferrari if they find themselves off the pace in what in the worst case scenario might almost be a two-tier field.<\/p>\n<p class=\"dcr-130mj7b\">With Audi also building their power unit for the first time, they expressed their misgivings at their car launch on Tuesday night in Dresden. \u201cIf it\u2019s real, it is certainly a significant gap in terms of performance and lap time, and that would make a difference when we come to competition,\u201d said their chief operating officer, Mattia Binotto. The German team\u2019s technical director, James Key, was already looking to the FIA. \u201cI think if it\u2019s sort of bypassing the intent of the regulations, then it has to be in some way controlled,\u201d he said. \u201cWe trust the FIA to do that.\u201d<\/p>\n<p class=\"dcr-130mj7b\">Crucially, it is unlikely there will be any change to the measurement procedures nor regulations in the short term. Although the FIA has stated that the regulations could at some point be revised. For the moment, however, if Mercedes, their customers and Red Bull really do enjoy a significant advantage in the early races, it might yet prove a gulf that cannot be bridged.<\/p>\n","protected":false},"excerpt":{"rendered":"Unveiling their new engine in Tokyo should have been a significant moment for Honda to celebrate but behind&hellip;\n","protected":false},"author":2,"featured_media":428435,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[573],"tags":[64,63,817,813,816,85],"class_list":{"0":"post-428434","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-formula-1","8":"tag-au","9":"tag-australia","10":"tag-f1","11":"tag-formula-1","12":"tag-formula1","13":"tag-sports"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/428434","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=428434"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/428434\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/428435"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=428434"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=428434"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=428434"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
