Mitsubishi PX-MiEV II AWD Hybrid SUV Concept unveiled

Mitsubishi Motors' unique Mitsubishi Plug-in Hybrid EV System is derived from the control systems used on EVs. For low to medium speed driving in town or residential areas, the vehicle operates in EV Mode where motive power comes from the two electric motors using power from the drive battery. When the residual charge in the drive battery drops to a predetermined level or when the driver needs more gutsy acceleration, the system switches to Series hybrid Mode where the gasoline engine automatically starts up and serves as a generator feeding power to both motors and to the battery.

At higher vehicle speeds, the system switches to Parallel hybrid Mode where the gasoline engine, with its better high-end energy efficiency, supplies supplementary drive torque to assist the motors. In addition when the driver applies the brakes, the front and rear motors act as generators recovering kinetic energy and using it to charge the drive battery.

The Mitsubishi Plug-in Hybrid EV System employs a high-capacity battery that is capable of powering the vehicle in EV Mode for distances of 50 kilometers. This range allows the vehicle to operate in EV Mode in most everyday situations. The driver can switch manually to Battery Mode for quiet and emissions-free all-electric driving in residential areas or the countryside.

The driver can also switch to Battery Charge Mode when he or she wants to reduce battery power consumption and use the engine to generate electricity. A socket on the vehicle allows electricity stored in the drive battery to be used to power electric appliances when camping or pursuing other outdoor activities, or to provide an emergency power source. The system is also vehicle-to-home (V2H) compatible.

EV Mode

The front and rear motors drive the vehicle using electricity from the drive battery. The car operates in this mode for commuting, shopping and most other everyday driving situation.

Series Hybrid Mode

In this mode the motors are powered by electricity from the drive battery and from the engine generator when residual charge in the battery is low or when accelerating and other times when higher motor output is needed.

Parallel Hybrid Mode

The car is driven by its electric motors and by the gasoline engine at higher vehicle speeds where the engine offers better efficiency.

Twin Motor 4WD

The Mitsubishi Concept PX-MiEV II uses a Twin Motor 4WD system in which two motors drive the front and rear axles independently. Being virtually lag-free and offering superior control, the motors ensure finer more precise control of the 4WD system. The Twin Motor 4WD system does away with the propeller shaft, hydraulic system and clutch plate used to connect the front and rear axles in conventional 4WD systems. This helps to reduce the drive torque losses associated.
S-AWC

Mitsubishi's S-AWC (Super All Wheel Control) system maximizes safety, stability and handling performance by using on-board sensors to constantly monitor driving patterns, road surfaces and other conditions as well as integrating control of its 4WD, Active Stability Control (ASC) and ABS (Anti-lock Braking System) component systems.

The Mitsubishi Concept PX-MiEV II uses a new version of Mitsubishi's S-AWC system which improves safety and driving performance for almost effortless handling. Working in tandem with the Mitsubishi Plug-in Hybrid EV System, S-AWC also contributes to better fuel efficiency.
