Frontwheel Drive Propulsion Rear Wheel Rotation Generate Energy

It's technically possible to have a front-wheel drive propulsion system and use the rear wheels to generate energy on an electric vehicle (EV). Here's how it could work:

  1. In-Wheel Motors on Rear Wheels: The rear wheels could be equipped with in-wheel electric motors. While the front wheels propel the vehicle, the rear in-wheel motors would act as generators when not actively driving the vehicle.

  2. Regenerative Braking on Rear Wheels: Even without in-wheel motors, regenerative braking could be applied to the rear wheels. When the driver brakes, the system could engage the rear brakes to create resistance, turning the rear wheels into generators that convert kinetic energy into electricity.

  3. Energy Transfer: The electricity generated by the rear wheels would be transferred to the battery or directly used to power onboard systems, increasing the overall efficiency and range of the EV.

Potential Challenges and Considerations:

  • Complexity: Implementing such a system would add complexity and cost to the vehicle's design and manufacturing.

  • Efficiency: The efficiency of energy generation from the rear wheels might not be as high as with dedicated regenerative braking systems on all wheels.

  • Weight and Space: Adding in-wheel motors or additional regenerative braking components to the rear wheels would increase the vehicle's weight and require extra space.


While theoretically possible, this concept is not widely implemented in current EVs due to the challenges mentioned above. However, with advancements in technology and increasing demand for energy-efficient vehicles, we might see more innovative solutions like this in the future.
