Parallel drive system

Parallel drive system

• A. Uses only the vehicle's internal combustion engine to drive the wheels.
• B. Uses the vehicle's ICE or electric motor to power the transmission to provide propulsion.
• C. Uses separate propulsion motors for each axle
• D. Is independent of the drivetrain

Answer: (B)

A parallel drive system means propulsion can come from either the internal combustion engine or an electric motor, with both sources connected to the same drivetrain through the transmission. This setup lets the wheels be driven directly by the engine, or by the electric motor, or by a combination of both, depending on speed, load, and battery state. That’s why the description stating that propulsion comes from the vehicle’s ICE or electric motor powering the transmission to move the car best captures the concept. It’s different from a series system, where the engine mostly powers a generator that feeds the motor, and from configurations with separate motors for each axle, which imply a different drivetrain arrangement.
