<\/p>\nFormula 1 has spent the better part of the year listening to complaints about its 2026 technical regulations, particularly around the power unit philosophy and all the complications with it and its 50\/50 split between electrical and combustion power.<\/p>\n
Many of those criticisms have merit. Some are overstated. None of them is likely to change much. The regulations are pretty much locked. The manufacturers have spent hundreds of millions building to them, and what many consider bugs are in reality features that were part of the regulatory framework long before the cars took to the track in public for the first time.<\/p>\n
The sport\u2019s bosses may tweak the rules slightly, but fans and drivers will have to adapt and move on.<\/p>\n
Experts have offered all types of possible \u2018fixes\u2019 to F1\u2019s current issues, from obvious ones to left-field ideas.<\/p>\n
Among them, a particular idea has resurfaced: if F1 needs to please the car manufacturers with its hybrid regulations, why not allow an alternative formula to run alongside the prescribed one?<\/p>\n
Let teams and manufacturers choose their own technical path, compete under a unified sporting framework but divergent engineering philosophies, and let the best solution win.<\/p>\n
It sounds, in theory, like a liberating proposal. In practice, however, Formula 1 already tried it and the results were far from encouraging.<\/p>\n
A two-tier series<\/p>\n
Between 1987 and 1988, Formula 1 ran two engine formulas simultaneously. It was not a grand philosophical experiment but a managed retreat: the FIA\u2019s attempt to wind down the turbo era gracefully while nurturing its successor.<\/p>\n
<\/p>\n
Turbo engines were still the way to go in 1987<\/p>\n

The turbocharged 1.5-litre formula that had dominated since Renault\u2019s pioneering efforts in the late 1970s had, by the mid-1980s, produced power outputs that were becoming genuinely alarming.<\/p>\n
In qualifying trim, the most extreme engines were producing something in excess of 1,000bhp from an engine barely larger than a modern road car\u2019s and without many of the safety measures currently protecting drivers.<\/p>\n
The FIA had concluded that the escalating power of the turbocharged engine was getting out of hand, and needed to find a way of bringing power down to more sane levels without alienating the car manufacturers who had recently brought unprecedented wealth to the series.<\/p>\n
The solution was a phased withdrawal.<\/p>\n
A glide-path was set out that would progressively neuter the turbos, ready for the blanket standardisation in 1989 of the normally-aspirated 3.5-litre motors that were permitted alongside the turbos from 1987.<\/p>\n
The dual formula was therefore not a permanent settlement but a transition mechanism, a device to give teams time to prepare, amortise existing turbo investment, and move predictably toward a single, standardised formula.<\/p>\n
In 1987, the turbo boost pressure was limited to 4 bar while the naturally-aspirated cars could use engines of up to 3.5 litres with no fuel restriction. The turbo runners were limited to 195 litres per race.<\/p>\n
To give the naturally-aspirated runners some symbolic recognition, the FIA created two supplementary championships contested solely by naturally-aspirated runners: the Jim Clark<\/a> Trophy for drivers and the Colin Chapman<\/a> Trophy for constructors.<\/p>\n The intention was to give the underdogs their own scoreboard, encourage investment in the new formula, and signal where things were headed.<\/p>\n The press was largely unimpressed, frequently referring to the naturally-aspirated runners as \u201cGroup B\u201d. Jonathan Palmer<\/a> won the Jim Clark Trophy driving for Tyrrell<\/a>, but almost nobody noticed.<\/p>\n The naturally-aspirated engines ran at the back of the field. Here, Palmer in the Tyrrell-Ford at Monza in 1987<\/p>\n \n Grand Prix Photo\n <\/p>\n The fundamental problem was that equivalent performance between two radically different power unit philosophies could not be legislated into existence with any precision.<\/p>\n The turbos were still enormously powerful even under restriction, and the non-turbo field was operating off essentially customer Cosworth architecture. The only naturally-aspirated engine in 1987 was the DFV-derived Ford-Cosworth DFZ 3.5-litre V8, producing around 575bhp. The turbo runners, even in their constrained state, were delivering considerably more.<\/p>\n Williams<\/a>\u2018 Honda<\/a>-powered cars won both championships as the dual formula had produced one class that competed for wins and another that competed against itself.<\/p>\n For 1988, the restrictions tightened even more. The boost limit was reduced to 2.5 bar, and the fuel allowance for turbo engines fell to 150 litres, while naturally-aspirated runners continued to carry and use unlimited fuel.<\/p>\n The explicit intention was to compress the performance gap so significantly that the transitional year would effectively serve as a preview of the new order, or at least something resembling a competition.<\/p>\n When initially announced, it was believed the restrictions would be so prohibitive as to render the turbo uncompetitive and bring the naturally-aspirated era in one year early.<\/p>\n Honda had other ideas, however. The Japanese manufacturer looked at what was possible for its turbo V6 within the tight restrictions and it decided it could still be competitive.<\/p>\n The result was the RA168E, an engine that used the severe fuel and boost constraints as an engineering brief rather than an obstacle. It achieved around 30% thermal efficiency, well ahead of the competition, and began the year with 640bhp in race trim, rising to 685bhp by season\u2019s end, with over 700bhp available in qualifying.<\/p>\n Ferrari<\/a> also stayed with turbos, modifying its 1987 unit with revised combustion chambers, though with less dramatic gains.<\/p>\n The outcome was the most one-sided season in Formula 1 history at the time.<\/p>\n The Honda-powered McLaren was unbeatable in 1988<\/p>\n \n Grand Prix Photo\n <\/p>\n Honda\u2019s RA168E, powering the McLaren<\/a> MP4\/4 driven by Ayrton Senna<\/a> and Alain Prost<\/a>, won 15 of the 16 races.<\/p>\n Four teams gambled on switching to naturally-aspirated power early, hoping to gain a development head-start ahead of the mandatory naturally-aspirated formula in 1989. Williams, having moved to Judd engines after losing Honda, went from constructors\u2019 champion to also-ran in a single winter.<\/p>\n The dual formula had not created a competitive spectacle. As a transition mechanism, it worked, as the grid was broadly prepared for 1989, and the entry list expanded considerably once the turbo complexity was stripped away, but as a framework for competitive racing, it was a study in the difficulty of equivalency.<\/p>\n It showed that you can\u2019t write a regulation that makes two fundamentally different technologies equal without one of them finding the gaps.<\/p>\n An unrealistic option<\/p>\n Which brings us back to the present\u2026<\/p>\n The appeal of a dual formula today is understandable, particularly when one side (drivers and fans) wants something completely different to the other (manufacturers and powers-that-be).<\/p>\n It\u2019s a simple argument: If the sport finds the 2026 regulations unworkable, why not allow a simpler alternative, perhaps a normally-aspirated or less hybridised unit, to compete alongside them?<\/p>\n The current rules are unlikely to change anytime soon<\/p>\n \n Grand Prix Photo\n <\/p>\n The answer is that the conditions that make such a thing viable barely exist.<\/p>\n The 1987-88 dual formula succeeded administratively because it had a fixed endpoint: everyone knew the turbos were going in 1989, and the whole exercise was about getting there in good order.<\/p>\n","protected":false},"excerpt":{"rendered":"Formula 1 has spent the better part of the year listening to complaints about its 2026 technical regulations,…\n","protected":false},"author":2,"featured_media":594731,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[573],"tags":[64,63,817,290265,813,816,85],"class_list":["post-594730","post","type-post","status-publish","format-standard","has-post-thumbnail","category-formula-1","tag-au","tag-australia","tag-f1","tag-f1-engine-regulations","tag-formula-1","tag-formula1","tag-sports"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/594730","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=594730"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/594730\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/594731"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=594730"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=594730"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=594730"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"Jonathan](\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2026\/04\/19870101F1-0078-800x450.jpg\"\/)
