Technician A says that in a parallel hybrid design, only the electric motor is connected to the transmission. Technician B says that in a parallel hybrid design, the vehicle can be propelled by the electric traction motor, the internal combustion engine, or both. Which technician is correct

Answer: Technician B is correct

Explanation:

Parallel hybrid systems have both an internal combustion engine and an electric motor that can both individually drive the car or both coupled up jointly giving drive.

The hybrid drive train consists of two separate power sources to propel the vehicle at various modes of driving. This type of transmission consists of gears, shafts and clutches that perform various operations such as gear selection much like a conventional transmission.
