An electrical drive train 200 for providing power to the wheels 60A, 60B of an electrical vehicle. An electrical motor 210 provides torque at its output shaft. A clutch arrangement 30 has an input shaft for receiving the torque from the electrical motor and an output shaft for providing a coupled output torque. The clutch arrangement couples torque from its input shaft to its output shaft when in an engaged state. The drive train further includes a gearbox arrangement 40 with an input shaft for receiving the coupled output torque from the clutch arrangement and an output shaft for providing a geared output torque. A differential gear arrangement 50 has an input shaft for receiving the geared output torque from the gearbox arrangement, and a pair of output shafts for driving the wheel arrangement. A drive train management system 250 may be included for providing clutch slip control, manual and automatic modes for the gearbox, and temporal filtering for changing the responsiveness of an acceleration signal. The drive train may be converted from an internal combustion engine drive train by replacing the engine with an electric motor. Regenerative braking may be provided. A corresponding method is also disclosed.
