Mitsubishi unveils hybrid MIEV 4WD sport compact concept

MIEV Powertrain Hints at High-Tech Mitsubishi Future

Mitsubishi is actively developing its MIEV technology to address future demands for improved fuel efficiency and reduced emissions, without sacrificing driving performance and fun. The series/parallel hybrid drive in the Concept-CT uses a special transmission to harness the 50 kW (67 horsepower) output of a 1.0-liter three-cylinder gasoline engine to drive the rear wheels and the generator. Engine power is 20kW per wheel. A 40 kW (54 horsepower) generator charges high-energy-density, lithium-ion batteries to offer high capacity and long life. Total combined peak power is 100kW (134 horsepower).

The MIEV system provides both economical cruising capability and high capacity power for short bursts of acceleration when needed. A regenerative brake system captures energy that would otherwise be lost as heat through the brake discs and channels it to the batteries.

Each of the Concept-CT's wheels houses an electric motor, effectively providing computer-controlled all-wheel drive (AWD) that can transfer optimal traction independently to each tire as needed. Such individual wheel control opens up new possibilities to enhance vehicle stability and performance.

In addition to a gasoline-electric hybrid powertrain featured in the Concept-CT, MIEV technology can be applied to pure battery electric vehicles and fuel cell electric vehicles to suit a wide variety of world market needs and infrastructures in the future. Mitsubishi is testing a MIEV powertrain in the Lancer Evo MIEV rally car acclaimed at the 2005 Tokyo Motor Show as an environmentally conscious, high-performance vehicle.

Adventurous Yet Practical Interior

The Concept-CT interior design is as adventurous as the exterior, starting with structural elements that also serve as design elements. The main controls take inspiration from motorcycle front forks and controls and are supported by a structure fashioned in parallel strips. For a clean, modern image, the interior features pearl finish, ribbed vinyl and soft-touch surfaces with copper accents.

The Concept-CT instrument panel is unlike anything seen in current vehicles. A wide format "wall to wall" screen displays information for navigation, rear/side-view mirror functions, and entertainment functions (when in park). Flat-screen gauges are placed well forward of the driver for optimal visibility. In addition, a flat screen in the center panel displays climate control and audio information. Reflecting Concept-CT's futuristic theme, the ultra-thin center console houses a fingerprint-reading security key and computer touch pad interface.
