Quibbles over Balance of Performance and accusations of sandbagging have been a near-constant feature of GT racing in recent times. Openly discussing the BoP isn’t permitted under the World Endurance Championship’s sporting regulations, but that’s not the only reason for grumbles being notably reduced this year as LMGT3 replaced GTE Am.
MagCanica is the FIA’s current supplier of torque meter sensors, which have been utilised since the outset of the Hypercar class in 2021 and have now migrated into the GT realm. Measuring torque from the driveshaft, they allow for live monitoring of power outputs so any spikes beyond what is allocated in the BoP are visible to the FIA and co-legislator Automobile Club de l’Ouest in real time. This is enforced by penalties, as seen with Toyota’s #8 Le Mans Hypercar at Spa in May.
