Question

Quizplus · Accepted Answer

Technician A is correct because in a series hybrid, the combustion engine powers a generator to produce electricity for the electric motor, primarily extending the driving range rather than directly propelling the vehicle. Technician B is incorrect because in a parallel hybrid, both the engine and electric motor can drive the wheels, with the engine often being the main power source during normal driving conditions, not the electric motor and batteries.
