FIA mandates Torque Sensors for this year’s edition of Macau’s GT World Cup
Torque sensors, devices enabling monitoring of powertrain parameters on track, will be mandatory in this year’s eighth running of the FIA GT World Cup, which will traditionally be held as part of the Macau Grand Prix

Torque sensors offer very high accuracy in measuring power, allowing the FIA to ensure that the power of each car does not exceed the Balance of Performance-allocated values and that that external factors like atmospheric conditions do not influence performance.
The sensors are installed on the driveshafts of the cars and are the most effective tool to measure power at the wheel, allocated individually by the BoP process to each car model taking part in the world’s most prestigious sprint race for GT3 machinery. The decision to mandate torque sensors followed consultations with the manufacturers involved in the GT3 Technical Working Group.
The FIA has extensive experience using torque sensors, with the devices being mandatory from a regulatory standpoint in the FIA World Endurance Championship’s Hypercar and LMGT3 classes, as well as in the ABB FIA Formula E World Championship and the FIA World Rally-Raid Championship’s Ultimate class.
The introduction of mandatory torque sensors is the second major FIA GT World Cup regulatory change for 2025, following the approval of the new Super Pole qualifying format by the FIA World Motor Sport Council this February.
The eighth edition of the FIA GT World Cup will take place from November 13–16 as part of the 72nd Macau Grand Prix.
Lutz Leif Linden, FIA GT Commission Chairman, said: “I'm delighted that we will be using torque sensors in the FIA GT World Cup in Macau this year. The FIA made this decision in consultation with the manufacturers. For us, this means even greater fairness and improved control of BoP values which is particularly important in such a prestigious and high-profile event and on a circuit as demanding as the one in Macau, where high-speed straights contrast with tight, narrowing corners. Following last year’s extremely competitive entry, this, along with the recently approved qualifying format, marks another key step in the FIA GT World Cup's ongoing growth."
Fabrice van Ertvelde, FIA Technical Circuit Sport Manager, said: “As always with competitions relying on Balance of Performance, our goal as the regulator is to ensure a level playing field for all participants. The implementation of torque sensors is a very effective tool to achieve that target, allowing us to realign all the very different cars on parameters such as pure power but also on top speed, which is a crucial factor on a track such as the Guia Circuit. The manufacturers we are expecting to see in Macau this year are already familiar with this innovation through their experience in the LMGT3 class in the FIA World Endurance Championship, and the decision to go with the torque sensor route is a result of a dialogue we had with them.”
