The SRT05e is designed to get twice the range of its predecessor, the first-generation Spark Renault SRT01, which has been in use for the series’ first four seasons. As the Verge notes, drivers currently have to switch vehicles mid-race in order to have enough charge to make it over the finish line, but bigger batteries currently in development are expected to make that headache a thing of the past. According to Spark, the SRT05e compensates for a heavier battery by dropping some weight from the chassis and getting more efficient with the aerodynamics and the drivetrain.”
