Powertrain
R2026bPowertrain systems include propulsion, drivetrain, and transmission subsystems. To configure the drivetrain subsystem, you can use the limited slip or open differential blocks. The propulsion blocks include mapped motor, compression-ignition (CI) engine, and spark-ignition (SI) engine blocks. For the transmission subsystem, you can use the ideal fixed gear transmission block.
