Understanding the Electric All-Wheel Control System

The Electric All-Wheel Control system in the Mitsubishi Outlander PHEV is a hallmark of the vehicle’s engineering excellence. Unlike traditional mechanical AWD systems that rely on complex driveline components like differentials and transfer cases, the Electric AWC employs two independent electric motors—one powering the front wheels and the other driving the rear wheels. This setup allows the system to deliver instant and precise torque adjustments to each axle, optimizing traction and handling without the lag associated with mechanical linkages.

Key Components and Functionality

  • Dual Electric Motors: One motor is mounted on the front axle and another on the rear axle. This arrangement allows for independent torque delivery, enabling seamless transitions between front-wheel drive, rear-wheel drive, or all-wheel drive modes as needed.
  • Advanced Traction Control: The system continuously monitors wheel speed, steering angle, throttle input, and road conditions through a network of sensors. Based on this data, the onboard computer dynamically allocates torque to prevent wheel slip and maintain stability.
  • Instant Torque Vectoring: Electric motors can vary torque output almost instantaneously. This means the system can adapt in real-time to changes in road grip, providing enhanced cornering performance and reducing understeer or oversteer tendencies.
  • Regenerative Braking Integration: The Electric AWC works in harmony with regenerative braking systems to recover energy when decelerating, channeling it back to the battery while maintaining vehicle stability.

Benefits of Electric All-Wheel Control

The Electric AWC system offers multiple advantages compared to traditional AWD setups, such as:

  • Improved Efficiency: By precisely controlling power delivery, the system minimizes energy waste, extending the vehicle’s electric driving range.
  • Enhanced Safety: Better traction and stability reduce the risk of skidding or losing control, especially in adverse weather conditions like rain, snow, or ice.
  • Smoother Ride Quality: The instant torque adjustments result in fluid and responsive handling, improving driver confidence and comfort.
  • Reduced Mechanical Complexity: With fewer moving mechanical parts compared to traditional AWD systems, there is less wear and tear, which can translate into lower maintenance costs over the vehicle’s lifespan.

Driving Modes and Adaptability

The Outlander PHEV’s Electric All-Wheel Control system is integrated with several driving modes that allow drivers to tailor the vehicle’s behavior based on terrain and driving preferences:

  • Normal Mode: Balances power distribution for everyday driving with an emphasis on efficiency and comfort.
  • Snow Mode: Optimizes torque to reduce wheel spin and maximize grip on slippery or snowy surfaces.
  • Gravel Mode: Adjusts the system to maintain stability and traction on loose or uneven gravel roads.
  • Lock Mode: Engages a more aggressive torque split for challenging off-road conditions where maximum traction is required.

These modes demonstrate the system’s adaptability, ensuring the Outlander PHEV performs confidently whether navigating city streets, highways, or rugged backroads.
