Is a Hybrid 4x4 the Future of Efficient and Versatile Driving?

Click For Summary
SUMMARY

Peugeot has introduced a new hybrid 4x4 system that combines a traditional front-wheel drive with an electric motor powering the rear wheels. This innovative design allows for multiple driving modes: internal combustion engine (ICE) with front-wheel drive for highway efficiency, electric-only rear-wheel drive for urban driving, and a combination of diesel front and electric rear for full 4x4 capability. The system also features regenerative braking using the rear wheels, enhancing energy efficiency. This approach reduces the cost and weight associated with conventional 4WD systems while improving traction through battery placement over the rear wheels.

PREREQUISITES
  • Understanding of hybrid vehicle technology
  • Knowledge of electric motor applications in automotive engineering
  • Familiarity with regenerative braking systems
  • Basic principles of vehicle dynamics and weight distribution
NEXT STEPS
  • Research Peugeot's hybrid 4x4 technology and its specifications
  • Explore the impact of weight distribution on vehicle grip and handling
  • Learn about regenerative braking systems and their efficiency in hybrid vehicles
  • Investigate other manufacturers' hybrid systems, such as Lexus's SUV models
USEFUL FOR

Automotive engineers, hybrid vehicle enthusiasts, and anyone interested in the future of efficient driving technologies.

Peugeot have a new hybrid 4x4
They took a regular front wheel drive car and added an electric motor driving the rear wheels only.
It can run ICE + front wheel only for freeways without the extra drag of permanent 4wd
Electric rear wheel only for in-town/traffic low speed, or Diesel front + electric rear for 4x4.
It can also do regenerative braking with the rear wheels.

The idea is that the cost+weight of the electric system + batteries is less than fitting a conventional 4wd system. And the weight of the batteries over the rear wheels helps the grip.

I'm pretty sure lexus did this a few years ago with one of their SUVs.
