GTE regulations required competitors to field genuine production-based grand touring cars — road-legal sports cars with two doors, homologated by the ACO in minimum production volumes. Factory entries with full works engineers ran in GTE Pro; customer or semi-works entries with older-specification cars and mixed amateur/professional driver pairings competed in GTE Am. Both classes ran simultaneously at each WEC round and at Le Mans, creating intra-class battles layered inside the prototype hierarchy.
The class traces to earlier GT designations — GT2, then Group GT — before receiving the GTE name at the WEC's founding in 2012. The underlying technical framework drew from the FIA GT3 rules philosophy: controlled homologation, Balance of Performance equalisation, and a strong link to the road car.
The GTE golden era from roughly 2016 to 2022 featured five major factory programmes:
[[ferrari-488-gte|Ferrari 488 GTE Evo]] — AF Corse's flat-plane-crank turbocharged weapon, successor to the 458 Italia GTE. Won back-to-back GTE Pro manufacturers' titles in 2017 and 2018.
[[porsche-911-rsr|Porsche 911 RSR]] — the Porsche GT Team's Le Mans weapon, distinguished by its mid-rear engine positioning (ahead of the rear axle, unlike any road 911) and natural aspiration into the late 2010s before switching to a twin-turbo unit.
[[corvette-racing|Corvette Racing]] C8.R — GM's entry built around the mid-engine C8 platform, representing a generational shift from the front-engine C7.R that had dominated the parallel GTLM class in [[imsa-weathertech-sportscar-championship|IMSA]].
[[aston-martin-vantage-gte|Aston Martin Vantage GTE]] — Prodrive-developed, run by Aston Martin Racing, using a Bamford-built twin-turbo V8 in the Vantage AMR body.
Ford GT — Ford's centenary programme entered for 2016–19 to return to Le Mans 50 years after 1966. Won GTE Pro outright on its Le Mans debut.
The ACO announced in 2021 that LMGTE Pro would conclude after the 2022 season, citing declining manufacturer interest as factory investment shifted toward the new Hypercar category. GTE Am ran one final season in 2023, its last race the 8 Hours of Bahrain. From 2024 the slot became LMGT3, opening to customer-accessible [[gt3-class-history|GT3]] machinery with cost-capped bodywork conversions.
GTE cars translate exceptionally into simulators. Their regulations are transparent, factory data well-documented, and the class sits between outright prototype pace and a relatable driving experience. [[iracing|iRacing]], Assetto Corsa Competizione, and rFactor 2 all feature GTE-specification cars. The [[ferrari-488-gte|488 GTE]] and [[porsche-911-rsr|911 RSR]] are among the most raced cars in competitive online endurance sim racing.
