Concept PX-MiEV
"At the heart of the Concept PX-MiEV there are three power systems, one permanent magnet synchronous electric motor in the front, another in back, and the highly efficient MIVEC gasoline engine which can power the front wheels and also serve as a generator. Controlled and optimized by the remarkable MiEV Operating System, the engine, electric motors and batteries work together to maximize efficiency and deliver impressive range."
"Here's how it works: At slow and moderate speeds (for example, a morning commute in the city), the Mitsubishi Plug-in Hybrid System operates in all-electric EV Mode. Here the Concept PX-MiEV becomes a front-wheel-drive vehicle, powered by its battery pack and the front electric motor. In short, it offers fun-to-drive power with zero tailpipe emissions. Furthermore, the Concept PX-MiEV monitors road conditions and adapts to them. So if it's raining, or if the road is slick with snow, electric power is automatically provided to the rear motor, supplementing the front-wheel-drive operation and effectively turning the car into an electric four-wheel-drive vehicle."
"Mitsubishi Concept-RA is powered by a new high-output, low-emission 2.2-liter 4-cylinder DOHC 16-valve turbo diesel engine. This engine features the Mitsubishi innovative Valve timing Electronic Control (MIVEC) system valvetrain that offers continuously-variable valve-timing control. The new diesel engine is equipped with piezoelectric injector common-rail direct fuel injection that allows a lower compression ratio and a VD (Variable Diffuser)/VG (Variable Geometry) turbocharger. The 2.2-liter engine delivers a maximum output of 201 hp and maximum torque of 310 ft.-lbs."
