1. i MiEV SPORT world first
Based on the i MiEV, the i MiEV SPORT enhances the "driving" image of Mitsubishi's electric vehicles. The car features Mitsubishi Motors' unique in-wheel motors in the front plus S-AWC (Super All Wheel Control) — the company's vehicle dynamics control system — to achieve high maneuverability as well as high levels of both environmental and running performance. The car brings a new closeness between people and cars; allowing them to become more a part of daily life.
The "fastback" exterior design expresses the quickness of the car with an appearance that is pleasing and lively. An efficient, environmentally friendly electric vehicle thanks to its compact size, it also possesses exceptionally fluid styling. A simplified interior styling creates a pleasant space, allowing occupants to feel at home. Geometry, metallic materials and body epitomize the futuristic electric vehicle. Interior lighting, too, has been carefully thought out, with the use of many blue LEDs suggestive of nature, creating a sophisticated, cutting-edge atmosphere.
The light green exterior marks another association with nature. The pearlescent paint, which shines when hit with direct light, brings feelings of advanced, futuristic technology and environmental peace of mind. The interior is sporty and dynamic as a result of the substantial use of mesh materials, while the space, with various natural elements, fosters feelings of both security and comfort.
Like the i MiEV, i MiEV Sport uses a rear-midship design in its layout. Making use of the relatively long wheelbase of this platform, a high-capacity lithium-ion battery is installed in the lowest area under the floor, and components including a motor and inverter are arranged beneath the luggage compartment. This layout provides optimal distribution of weight, front and rear, and a lower center of gravity for stability, sporty performance, and a spacious interior.
An aluminum space frame — a combination of aluminum extrusions and aluminum die casting — is light, rigid and strong; helping to improving performance by minimizing weight.
The optimum layout of structural members, including front-side and cross members, efficiently absorbs crash energy in the event of front-end or side collision. In a collision from the rear, EV components under the back seat and rear floor serve as a barrier to ensure the integrity of the passenger compartment. By making use of the rear-midship layout and utilizing Mitsubishi's latest RISE (Reinforced Impact Safety Evolution) body, the concept realizes excellent occupant protection in collisions from any direction, even when colliding with a vehicle of different height or weight.
Powertrain / S-AWC
The system employs a structure consisting of three permanent magnetic synchronous motors. One in-wheel motor is placed at each front wheel; a single motor drives the rear wheels, as is used in the "i MiEV" system. An E-4WD system electronically optimizes the output of all motors. In addition, a new E-AYC (Electric Active Yaw Control) system is employed to directly regulate torque at the left and right rear wheels via an electric motor. In addition to the E-4WD and E-AYC, the S-AWC system integrates ABS and ASC (Active Stability Control) systems, thus independently controlling driving force, traction and braking at all four wheels, for total maneuverability and maximum stability.
Energy Saving Technology/Environmental Technology
Energy-saving environmental considerations are seen throughout the i MiEV SPORT. Effective use of energy is achieved by installing an auxiliary photovoltaic generator on the roof, a power-generating fan inside the front grill, and regenerative braking functions to recover energy when the car is slowing down. Much of the lighting is by bright, power-saving LEDs, including in the rear combination lamps and vehicle interior, and the efficiency of the air conditioning is enhanced by the use of heat-absorbing window glass. In addition, Green Plastic — Mitsubishi Motors' unique plant-based resin technology — is used wherever possible for interior components in another nod to the environment.

2. MITSUBISHI Concept-ZT world first
By combining a high-powered, fuel-efficient, 2.2-liter clean diesel engine and Twin Clutch SST, and using significant quantities of Green Plastic in the interior, a high level of running and environmental performance is achieved. In addition to advanced active safety technology, Concept-ZT achieves a high level of passive safety. Features include pre-crash safety; a lane-drift warning system; driving assistance technology, including new all-around multi-monitors and a parking assistance system; and crashworthiness safety technology including a pop-up hood. Moreover, equipped with the S-AWC system combining front E-LSD (Electric control - Limited Slip Differential), ABS and ASC, based on Mitsubishi Motors' 4WD electronic control system, the MITSUBISHI Concept-ZT is a premium sedan that possesses dramatically improved driving, environmental and safety performance.
The basic exterior form, simple and flowing with a low center of gravity, yields a sense of stability and sportiness fitting Mitsubishi Motors' premier sedan This base is combined with a powerful shoulder line, substantial side panels and projecting fenders. Sculptured headlights, grill and aluminum wheels proclaim quality and status created out of "Japanese" sensitivity — a sophisticated and adult sensibility.
In the interior, the goal was a level of "hospitality" that would resonate with all the senses of the occupants. Combinations of designs with clear contrasts — simple forms with overall continuity gently embrace passengers and precise, hard functional parts — express the melding of quality, comfort and the pleasure of driving. Meters and monitors are of clear materials, futuristically stacked, with the beauty of industrial art.
Minute quantities of a new reflective material add elegance to the body color. In combination with decorative parts, including wheels and grill, a radiant presence is realized with a sense of quality and refinement, like jeweled layers of precious metals. Interior colors are a combination of grained black wood, metal and leather, making maximum use of materials expressing boldness, sophistication and grace.
The concept's powerplant is a newly developed 2.2-liter 4-cylinder DOHC, 16-valve with VD (Variable Diffuser)/VG (Variable Geometry) clean turbodiesel engine with common-rail direct fuel injection (piezoelectric injector) that delivers a maximum output of 140 kW and maximum torque of 400 Nm.
The power unit is mated to Mitsubishi's new Twin Clutch SST, which delivers superior power transmission efficiency in a powertrain that realizes smooth, responsive, effortless power and acceleration, whether on the highway or in urban areas, together with good fuel economy. The S-AWC system combines front E-LSD (Electric control - Limited Slip Differential), ABS and ASC with the 4WD electronic control system also used in Outlander and Delica D:5. This optimally controls driving force, traction and braking at all four wheels, and provides stable driving on various road surfaces under various conditions, realizing a pleasurable and safe driving experience.
As in the i MiEV SPORT, the aluminum space frame structure combines aluminum extrusion and aluminum die casting, not only realizing a body of great strength and rigidity, but contributing to weight reduction and crashworthiness. In addition, for the outer panels of hoods, fenders, doors and trunk lids, shock-resistant, recyclable resin is used, as seen on the front fender of the Delica D:5.
Safety Technology/Driving Assistance Technology
Pre-crash Safety System: Using millimeter-length radar waves, the system detects cars far ahead as well as obstacles in the adjacent lane. When it determines that objects near the car are too close and there is danger of a collision, it warns the driver to take action. If the system determines that the possibility of a collision is nevertheless quite high, it pretensions seat belts and activates crash-restraint seat cushions to increase passenger restraint, and initiates emergency braking to reduce the impact of an imminent collision.
Lane-Drift Warning System: The system consists of a front camera, steering angle sensor, speed sensor, yaw rate sensor and ECU. The front camera recognizes lane markings (white lines, etc.), and the system, based on information from the other sensors, calculates the possibility of the vehicle drifting out of its lane, warns the driver, and adds steering torque in the direction such that the car stays within the lane.
Pop-Up Hood: If the car should hit a pedestrian, the hood pops up before the person's head strikes the hood, acting as a buffer and minimizing injury to the head.
New All-Around Multi-Monitors: In addition to a nose-view camera and a rear-view camera, cameras with extremely wide-angle lenses are positioned at the left and right sides. Optical distortions of the images from the four cameras are corrected, and the information is converted into a display of the situation all around the car as seen from the top — thus enabling clear confirmation by the driver. The nose camera is also part of the proximity-detection function for approaching objects.
Parking Assistance System: A distance sensor, embedded in the bumper, assesses the space available for parking. If parking is possible, the system will automatically maneuver the wheels (steering) while all the driver must do is control braking.
