The regular 2026 World Endurance Championship grid is deliberately simple. Seventeen Hypercars from eight manufacturers contest the top class, while eighteen LMGT3 cars from nine manufacturers form the second category. Outside the 24 Hours of Le Mans, that is the full championship structure. LMP2 remains part of Le Mans, but it has not been a regular WEC class since 2024.

The simplicity ends there. Both categories use Balance of Performance, yet the mechanisms around it are not identical. Hypercar is primarily controlled through the measured performance of the machine. LMGT3 adds another layer: the composition and recent results of the crew.

Hypercar: controlling the car

Hypercar brings two technical routes into one competition. LMH allows a manufacturer to define the complete vehicle concept. LMDh uses a licensed chassis platform and common hybrid components. BoP exists so those different engineering solutions can race within the same performance range.

TECHNICAL DIAGRAM: BOP AND POWER MEASUREMENT

The category is built around a minimum design weight of 1,030 kg and a regulated power framework. Event-specific BoP can then adjust mass and power. Torque meters on the driveshafts allow the FIA and ACO to monitor the output that actually reaches the wheels rather than relying only on declared engine figures.

The 2026 sporting regulations also allow a success handicap to be imposed in Hypercar. The handicap can be converted into mass, power or both. It applies at championship rounds other than the 24 Hours of Le Mans.

LMGT3: controlling the car and the crew

LMGT3 starts with the FIA GT3 platform. It is production-based, uses Goodyear tyres in WEC and is also subject to BoP. The technical equalisation therefore still matters, but it is not the only instrument shaping the class.

Driver categorisation is part of the sporting structure. A crew of two or three drivers must include at least one Bronze-rated driver, plus another Bronze or Silver driver. Hypercar crews are free in composition as long as they do not include a Bronze driver.

That changes strategy. An LMGT3 team must plan around minimum driving times and the abilities of differently graded drivers. The Bronze-rated driver is not a weakness to hide, but a mandatory part of how the category is designed. Qualifying and race strategy have to account for that reality.

Success handicap is a second correction

LMGT3 combines BoP with a result-sensitive success handicap. The 2026 regulations permit the system in both categories, with the calculated lap-time effect translated into mass, power or a combination of the two. Le Mans is excluded.

This distinction matters because BoP and success handicap answer different questions. BoP asks whether different cars have a comparable performance potential. Success handicap responds to recent competitive results. One starts with the technical object; the other reacts to what the object and its crew have achieved.

What the result sheet cannot show

A finishing order lists positions, gaps and lap times. It does not show every regulatory input that helped create them. In Hypercar, architecture, homologation, power control and BoP sit behind the number. In LMGT3, the same technical framework is joined by driver grading, mandatory driving time and a result-sensitive handicap.

That is the real difference between the classes. Hypercar asks how far manufacturers can diverge while being brought back into one performance window. LMGT3 asks the same technical question, then adds a sporting structure built around mixed driver grades.
