In the current season of the WeatherTech SportsCar Championship, both GTD Pro and GTD cars are now equipped with torque sensors on their rear axles, a first-time addition aimed at aligning performance balancing methods with those used in FIA WEC and ELMS LMGT3 classes. These sensors provide real-time data on acceleration, horsepower, and torque curves to aid in the Balance of Performance process throughout the season. Despite the substantial cost for teams estimated at $250,000 per car annually, this move has been generally well-received within the racing community. While most manufacturers have smoothly adapted to this new system due to similarities with LMGT3 components, Mercedes-AMG faces a learning curve as they navigate this technology for the first time in 2025, particularly evident in Daytona with their AMG GT3 entries. Mercedes-AMG acknowledges the need to gather data and adapt quickly to match the pace set by competitors, expressing optimism for a fair and competitive season once the kinks are ironed out. Teams like Winward Racing are working fervently to optimize the sensor system and overcome challenges encountered during the Roar sessions, showcasing a collective effort to tackle uncertainties ahead of the Rolex 24 event.
