2009 Mitsubishi i MiEV Sport Air

Press release

The i MiEV SPORT AIR is a concept for a sporty electric vehicle (hence SPORT) that gives an indication of the direction EVs may take in the future. It also gives shape to MMC’s "Drive@earth" tagline announcing the company’s intention to deliver fun-to-drive motoring while at the same time placing a new emphasis on environmental issues. The concept model is distinguished by its detachable "clear cutaway" roof panel which brings a wide open feel to the interior (hence AIR) for an exhilarating motoring experience,other features include a second-generation lithium-ion battery module with improved electrodes, while the body uses a number of new weight-reducing technologies.

Design

i MiEV SPORT AIR takes i MiEV’s rear-midship platform and mounts on it a dramatic teardrop-shaped body that tapers towards the rear in a design that yields outstanding aerodynamic performance. The styling also crafts a sporty image by seamlessly integrating an extensive glazed area with the body. Other design features include the front and rear lamp units cleanly styled to produce a three-dimensional look; as well as the "clear cutaway" roof panel, designed to provide an exhilarating motoring experience. The panel incorporates a solar inlay that uses printed circuit board graphics in its design.

Inside, i MiEV SPORT AIR offers a welcoming ambience in a design that uses organic shapes and lighting to create a comfortable and restful space. The wrap-around cockpit design, on the other hand, is styled to alert the driver to the high performance potential of the car the moment he sits behind the wheel. The main controls and switches are all ergonomically grouped around the dial-type shifter, making for more positive location and operation by the driver.

i MiEV SPORT AIR features exterior and interior coloring that takes "Japanese Technology" as its theme in projecting both a friendly, approachable image and high-tech looks. The blue exterior color evokes the image of an exhilarating clear blue sky, while the use of pearl finish paint gives a sheen to the body highlights for an overall appearance that is both friendly and futuristic while also projecting an eco-friendly image. The interior uses a high-contrast color scheme of greyish blue and "greige" (an intermediate color between grey and beige.) With the use of blue illumination for the instruments and interior lighting this two-tone scheme imparts an advanced and high-tech look to the cabin while at the same time producing a relaxing and reassuring atmosphere.

EV system

i MiEV SPORT AIR employs the same rear-midship layout as i MiEV but uses a more powerful version of the permanent magnet synchronous electric motor that powers the base model, generating 60 kW of power (against i MiEV’s 47 kW) and 230 Nm of torque (180 Nm.) The car also exploits its long wheelbase to locate the large-capacity lithium-ion battery system under the floor deck.

Body

To lower the center of gravity and increase driving stability the main EV system components (battery module, inverter, battery charger) are located as low as possible. The roof panel is made of lightweight plastic to facilitate fitting and removal as well as to further lower the car’s center of gravity.

i MiEV SPORT AIR ’s modular body structure uses tailgate panels and plastic body to reduce weight around the rear axle where the powertrain and EV system components are installed and thereby achieve an ideal 50:50 front/rear weight distribution. Of hybrid design, the body uses aluminum for the rear suspension and rear body.
