How virtual energy has become a defining principle in Hypercar racing
The IMSA SportsCar Championship underwent significant changes for the 2023 season, implementing new rules and regulations. The introduction of a spec hybrid system and the transition from DPi to LMDh resulted in a shift in energy usage calculations. The focus is now on how a car utilizes energy from a virtual tank, which includes fuel consumption and torque produced by the hybrid system. Maximum Stint Energy is measured by sensors attached to the rear axle and determines the primary concern for race strategy rather than fuel numbers alone. The Balance of Performance sets the stint energy and replenishment rate for each car and track, ensuring a level playing field. Exceeding the stint energy limit incurs penalties, starting with a 100-second hold during pit stops. Engineers play a vital role in managing the complex parameters and providing guidance to drivers. These changes have required teams to adapt and understand the new system, relying on both real and virtual tank figures to navigate the race.
