Mitsubishi Motors Corp exhibited a structural model of the "Mitsubishi Plug-in Hybrid EV System," which will be mounted in a plug-in hybrid electric vehicle (PHEV) that the company plans to release in fiscal 2012.

The structural model was showed at Automotive Engineering Exposition 2012, which took place from May 23 to 25, 2012, in Yokohama, Japan.

The system will be mounted in an SUV (sport-utility vehicle) that can travel about 50km (approx 31 miles) with only the electricity stored in the battery. When its gas tank is full and its battery is fully charged, it can travel 800km (approx 497 miles). Mitsubishi Motors aims to realize a "plug-in hybrid fuel consumption rate" of 60km/L (approx 141mpg). The rate is calculated based on the fuel efficiencies of a vehicle as both an electric vehicle and a hybrid vehicle.

The structural model was made by adding an engine, motors, etc to a simple chassis made with pipes. The engine, which was mounted on the front side of the chassis, was designed based on the "4B," which is used for Mitsubishi Motors' "RVR." The structural model has two permanent-magnet synchronous motors. The output powers of the front and rear motors were 70kW and 60kW, respectively.
