At this week’s three-day IMSA test at Daytona International Speedway, approximately 30 cars from all four WeatherTech SportsCar Championship classes will be in attendance. A new twist for this outing is the implementation of torque sensors on the supercars in the GT Daytona and GT Daytona Pro categories. IMSA introduced torque sensors in 2023 within its hybrid Grand Touring Prototype cars, and now aims to expand this technology to include all GTD models in 2025 for improved Balance of Performance information gathering. These miniature chassis dynamometers attached to the rear axles provide constant performance data and help detect any BoP violations. IMSA’s technical staff will use Magcanica torque sensors to balance the wide array of GT entries from different manufacturers. The sensors will track engine output and acceleration figures, ensuring compliance with BoP limits set by IMSA. The November test at Daytona serves as an opportunity for GT teams to familiarize themselves with this new technology before the Rolex 24 At Daytona in January.
