Classes, rules and the road"},"content":{"rendered":"<p>On Sunday 14 June 2026 the number 7 Toyota of Mike Conway, Kamui Kobayashi and Nyck de Vries won the 94th 24 Hours of Le Mans after a nail-biting finish against BMW. In twenty-four hours it had covered 381 laps, more than 5,190 kilometres, and it ended a run of three consecutive Ferrari wins. For Toyota it was a sixth victory at the Sarthe, the first since 2022.<\/p>\n<p>Once the race was over, the straight on which the Hypercars had spent a good share of those kilometres went back to what it is for the rest of the year: a stretch of the RD 338, a French departmental road open to traffic. That is the simplest way to understand why <strong>Le Mans cars<\/strong> are different from every other race car: they race on a track that is largely road, for a whole day, alongside cars that have little in common with them.<\/p>\n<div class=\"new-blog-inline-cta\"><\/p><div><strong>In short<\/strong><\/p><ul><li>Three classes race together at the 24 Hours, each with its own classification: Hypercar, LMP2 and LMGT3. In 2026 there were 62 cars: 18 Hypercars, 19 LMP2s and 25 LMGT3s.<\/li><li>Hypercars follow two different rulebooks, LMH and LMDh, which the Balance of Performance levels race by race.<\/li><li>The Circuit de la Sarthe is 13.626 kilometres long and part of the layout is a public road for the rest of the year.<\/li><li>None of the cars in the race is road legal. The LMGT3 cars, however, are derived from models you can buy at a dealership.<\/li><\/ul><\/div><p><\/div>\n<h2>Three races inside the same race<\/h2>\n<p>The first thing to know is that there is no single Le Mans car. There are three classes on track that start together, lap each other constantly and each have their own classification. In 2026 the grid counted 62 cars: 18 Hypercars, 19 LMP2s and 25 LMGT3s.<\/p>\n<p>The Hypercars are the prototypes fighting for overall victory, the ones run by manufacturers such as Toyota, Ferrari, BMW and Cadillac. The LMP2s are simpler, cheaper prototypes designed for private teams: they all use the same Gibson V8 engine and in 2026 they were all Oreca 07s. Since 2024, in the World Endurance Championship, they only race at Le Mans, because their class no longer exists for the rest of the season. Finally, the LMGT3s are the grand tourers, Porsche 911, Ferrari 296, Corvette Z06 and the rest: racing cousins of cars you can also find at a dealership, which arrived in 2024 in place of the old GTE cars.<\/p>\n<p>Three families this different on the same track, for twenty-four hours, are already reason enough not to resemble anything else. The Hypercars lap the LMGT3s constantly, by day and by night, and drivers have to factor in traffic as much as the stopwatch.<\/p>\n<h2>A track that is a road for the rest of the year<\/h2>\n<p>The Circuit de la Sarthe is 13.626 kilometres long and mixes sections of permanent circuit with roads that stay open to traffic when there is no racing. The most famous is the Hunaudi\u00e8res straight, known abroad as the Mulsanne: it once ran straight for about six kilometres and cars reached close to 400 km\/h on it, with tyres and engines that did not always survive. In 1990 two chicanes were added to break it up, partly because the FIA would no longer approve circuits with straights that long.<\/p>\n<p>On a track with so many fast sections, drag matters above all, but the shape of a Hypercar is decided first of all by the rules: they set the same aerodynamic efficiency window for everyone and a single homologated configuration for the season, and the bodies are long, low and clean. Then there is the duration: a twenty-four-hour race demands brakes, gearbox and suspension that make it to the end, headlights that allow drivers to run at race pace at night, and cockpits in which drivers swap several times.<\/p>\n<h2>Two rulebooks, one classification<\/h2>\n<p>Two ways of building a car coexist inside the Hypercar class. The LMH rules leave the design of chassis, engine and hybrid to the manufacturer: this is the route taken by Toyota, Ferrari, Peugeot and Aston Martin, which races without a hybrid. The electric motor, if there is one, goes on the front axle and can only be used above a certain speed. The LMDh rules, written by the ACO together with the American IMSA championship, start instead from a chassis supplied by one of the four approved constructors, Dallara, Ligier, Multimatic and Oreca, and from a hybrid system that is the same for everyone: a Bosch electric motor delivering 50 kW under power, a Williams battery and an Xtrac gearbox. It is the route chosen by BMW, Cadillac, Alpine and Genesis, partly because it costs less: chassis and hybrid come from common suppliers.<\/p>\n<p>What holds the two families together is the Balance of Performance: before every race the FIA and the ACO adjust the power, weight and energy available to each model, so that all of them can lap in similar times. That is why a Hypercar is not the fastest car a manufacturer could build, but the fastest the rules allow it to bring to the track.<\/p>\n<h2>Slower than ten years ago, and not by accident<\/h2>\n<p>The lap record at the Sarthe, by average speed, still belongs to Kamui Kobayashi in 2017: 3:14.791 in qualifying, at an average of almost 252 km\/h, in the Toyota TS050 Hybrid, an LMP1 car from the era when manufacturers spent almost without limits. In 2026 pole went to the number 15 BMW with Dries Vanthoor in 3:22.564, after Jack Aitken&#8217;s Cadillac, five thousandths faster, had been demoted for an infringement. Almost eight seconds of difference, despite everything technology has done in the meantime.<\/p>\n<p>It is not a step backwards. In the final years of LMP1, from 2018, Toyota had been left as the class&#8217;s only factory manufacturer; the Hypercars were created partly to bring many of them back, with rules that keep costs under control. Judging by the grid, the sums have added up.<\/p>\n<h2>Are Le Mans cars street legal?<\/h2>\n<p>No, none of those in the race. Hypercars and LMP2s are prototypes built for the track: no road homologation, no number plate. The LMGT3s are a separate case, because the GT3 rules require them to be derived from series models in production and on sale. The racing version, however, is a different car, and to drive it on the road it would have to be rebuilt almost from scratch: lights, emissions, noise, pedestrian safety, insurance.<\/p>\n<p>It was not always like this. In the 1990s the GT1 class rules required manufacturers to build road versions of their race cars as well, and that is how the Porsche 911 GT1 Stra\u00dfenversion and the Mercedes CLK GTR, which raced in the FIA GT championship, came about: race cars with number plates and homologated headlights, sold to a few very wealthy customers.<\/p>\n<p>Today the road runs in both directions. Ferrari sells customers the 499P Modificata, derived from the car that won Le Mans in 2023, but for the track only: it is not road legal and cannot race in any championship. Aston Martin did the opposite: from the Valkyrie, a road-going hypercar with a 6.5-litre Cosworth V12, it derived the Valkyrie AMR-LMH, which has raced in the World Championship and at Le Mans since 2025 and is homologated as a prototype, not as a modified series car.<\/p>\n<h2>What a brand sees<\/h2>\n<p>For a company this variety is an advantage. In the same week and on the same circuit you find the car manufacturers of the Hypercars, the private teams of LMP2 and the customer teams of LMGT3, with very different budgets and audiences. What a brand can buy at the 24 Hours is covered in our guide to <a href=\"https:\/\/rtrsports.com\/en\/blog\/sponsorship-at-the-24-hours-of-le-mans-what-a-brand-can-buy-and-what-it-gets-in-return\/\">sponsorship at the 24 Hours of Le Mans<\/a>; anyone thinking about the whole season will find the picture on our page about <a href=\"https:\/\/rtrsports.com\/en\/fia-world-endurance-championship-wec-sponsorship\/\">WEC sponsorship<\/a>.
