Torque sensors

Torque sensors are measurement devices fitted to the driveshafts of Hypercar-era machinery that record the power actually delivered to the wheels, continuously, in the regulator's data. They are the enforcement layer that makes Balance of Performance more than an honour system: declared power curves can be checked against physical reality.

Their arrival changed the balancing argument's terms. Sandbagging by under-reporting performance is far harder when deployment is measured at the axle, and penalties for exceeding permitted power are grounded in sensor data rather than inference.
