Mitsubishi's Concept PX-MiEV is another addition to the company's MiEV concept hybrid vehicle range. The concept went on display for the first time at the 2009 Tokyo Motor Show.

The exterior styling of the PX-MiEV is not that interesting, but at least it sticks to the design brief of something that is "solid, safe and simple". Mitsubishi wanted a vehicle which eschewed all the usual rugged features of typical SUVs, and instead had basic and simple uncluttered lines. The silver paint was specially developed for the vehicle and is designed to give the car a metal shell-like appearance.

Thankfully despite the dull exterior styling the Mitsubishi Concept PX-MiEV has some interesting technology underneath.

The PX-MiEV has a plug-in hybrid drivetrain which uses two electric motors and a 1.6 litre MIVEC internal combustion engine. The Mitsubishi Concept PX-MiEV also utilizes the MiEV OS (MiEV Operating System) which selects the optimum drive mode at all times.

The different drive modes of the Concept PX-Miev include:

Full Electric Mode: At low to middle vehicle speeds the Mitsubishi Concept PX-MiEV’s drive battery powers the front motor using front-wheel drive. When driving on snow, in the rain or in other low surface friction situations where maximum vehicle stability is required, the system automatically switches to four-wheel drive mode by feeding power to the rear wheel motor as well when sensors detect any front wheel slip.

Series Hybrid Mode: When the remaining energy in the drive battery falls to a predetermined level the system starts the gasoline engine to generate electricity and automatically switches to the series hybrid mode using the electricity generated to power the motors. In this mode as well, the system switches to four-wheel drive by driving the rear motor depending on driving conditions.

Parallel Hybrid Mode: At higher vehicle speeds the car is supported by the gasoline engine which operates more efficiently than the electric motors at high revolutions. In this mode, the gasoline engine also helps drive the wheels. When the driver makes sudden lane changes or other maneuvers requiring greater vehicle stability the system switches to four-wheel drive by bringing in the rear motor to drive the rear wheels, improving stability. In addition when overtaking at higher speeds or in other situations requiring faster acceleration the system switches in both front and rear motors to provide additional power and assist the gasoline engine, providing high acceleration.

Regenerative Mode: When the vehicle is slowing or coasting down a long descending slope the system switches to regenerative mode in which kinetic energy reclaimed from the wheels is stored in the drive battery.

The interior of the Mitsubishi PX-MiEV features the company's peculiarly named 'cocochi-interior' design. This system is designed to offer the occupants a "Clean, Stress-free and Safe & Reassuring" environment, but why Mitsubishi have to give their interior design a stupid name is beyond me.

The seat coverings have a special fabric which is designed to deactivate allergens, break down offensive odor molecules, and kill bacteria.

In order to cut down on electrical power consumption the interior of the PX-MiEV is protected by heat and infrared reflecting glass which helps keep the interior cool and reduce the need for air-conditioning.
