The 2021 championship was due to see a significant overhaul of the technical regulations in the top class of competition. TheLMP1 Prototypes used in the top class for the first eight years of the championship had been phased out and replaced by a new prototype specification known asLe Mans Hypercars (LMH). However, non-hybrid LMP1 cars were permitted to be "grandfathered" into the season.[1]
The 2021 championship also marked the return to an annual calendar for the World Endurance Championship, switching back to a summer calendar after the late running of theprevious season due to theCOVID-19 pandemic.[2]
A calendar was revealed in December 2019 at the8 Hours of Bahrain.[3] Due to theCOVID-19 pandemic, theprevious season was extended into November 2020. However, the 2021 season returned to an annual calendar entirely instead of a winter calendar.[2] A calendar for the 2021 season was announced during the2020 24 Hours of Le Mans event. The calendar featured six rounds as opposed to eight and saw the removal of the6 Hours of Silverstone,6 Hours of Shanghai andLone Star Le Mans when compared with the 2019–20 calendar as well as the addition of the6 Hours of Monza.[4] The decision to run a six-round series was made to save on costs due to the financial impact of the pandemic.[5] The1000 Miles of Sebring was initially scheduled for 19 March 2021 as the first round of the season, but was cancelled in response to theCOVID-19 pandemic and replaced by a race of the same length at Portimão on 4 April 2021.[6] That same race would also be itself later postponed to 13 June, making Spa the site of the preseason Prologue and the first race of the season.[7] The 24 Hours of Le Mans was originally scheduled to be run on the 12 and 13 June but was later postponed until 21–22 August for an increased chance of running the race with spectators.[8] The 6 Hours of Fuji was cancelled due to ongoing travel restrictions in Japan, and was replaced by a 6-hour event in Bahrain.[9]
The championship introduced theLe Mans Hypercar category as a replacement for theLe Mans Prototype 1 class.[15][16] Manufacturers are free to build and enter bespoke designs withouthomologation requirement or cars based on existing road-going models subject to a homologation requirement of building at least twenty road-legal models over a two-year period.[17] The cars have a minimum weight of 1,030 kg (2,270 lb), and power output is capped at 680 hp (510 kW) in order to achieve a benchmark lap time of three minutes and thirty seconds at theCircuit de la Sarthe.[17] Hybrid energy-recovery systems are allowed on the front axle only, and cars can derive up to 272 hp (203 kW) of their total power output from those systems. A Balance of Performance system modelled on the system used by the GTE class is applied to ensure parity between hybrid and non-hybrid models.[17] Manufacturers are given greater freedoms in designing the bodywork of Hypercars compared to Le Mans Prototypes provided that bodywork styling does not affect safety standards.[17] LMP2 cars received a power decrease of 40 horsepower, to 560 horsepower, in order to maintain the performance gap between the new top class and LMP2. A specification tyre was introduced in LMP2, produced byGoodyear, ending the tyre war between Goodyear andMichelin.[18]
Toyota announced plans to enter the championship under the Hypercar regulations with a bespoke car based on theGR Super Sport Concept.[19] Toyota launched their GR010 Hybrid on 15 January 2021.[20] In June 2020, boutique car manufacturerScuderia Cameron Glickenhaus committed to a two-car effort with theSCG 007 LMH, in partnership with 1989 24 Hours of Le Mans winnersSauber Motorsport, 15-time Le Mans winnersJoest Racing, and engine specialists Pipo Moteurs.[21][22][23][24] At the 2020 24 Hours of Le Mans, LMP1 competitors ByKolles Racing Team committed to a hypercar programme with its own car, the PMC Project LMH, but the team were not present on the entry list announced ahead of the 2021 season.[25][26][27]Aston Martin initially planned to enter a car based on theValkyrie road-going model.[19] However, the British manufacturer later decided to put its Le Mans Hypercar program on hold.[28][29] Long-time LMP1privateer teamRebellion Racing will end its racing operations at the end of the2019–20 season,[30] despite having previously announced the joint development of a Hypercar withPeugeot.[31] Peugeot itself has announce plans to compete from 2022 onwards, and announcedLigier Automotive as a partner in its project.[32][33][34][35]Alpine announced that it will enter the championship using a single rebadgedRebellion R13 LMP1, run bySignatech Alpine.[36][37][38] In LMGTE Pro,Aston Martin Racing ended its factory GTE Pro program run byProdrive to focus on their Formula One team and their LMGTE Am program.[39]
