Mitsubishi has just revealed the production model of its i-MiEV electric car in Japan and it plans to have models on the road by July. Initial sales of 1,400 vehicles will be to government entities with public sales starting in April of 2010.
As a full-electric vehicle the i-MiEV creates zero emissions and is powered by an electric motor and a lithium-ion battery pack that makes 63hp and 133 ft-lbs of torque.
It is based on Mitsubishi’s “i” minicar and by locating the drive battery under the floor and the power unit under the luggage compartment, it not only retains a great deal of usable cargo space, but is also a well-balanced vehicle.
Mitsubishi calls it the “ultimate eco-car, a solution to the various challenges the automobile faces today including environmental pollution, global warming and the depletion of petroleum-based energy supplies.”
The battery can be recharged using either a conventional household outlet, a 200-volt outlet or it can be quick-charged at special stations – which Mitsubishi is currently setting up in Japan. With a standard household outlet, charge time is 14 hours, but can be sped up to 7 hours using a 200-volt outlet. Quick-charge stations will be able to make the charge in just half an hour.
The i-MiEV is priced at 4,599,000 Yen ($47,600) but is eligible for a $14,400 tax break.
Mitsubishi did not give any details on when the car might go on sale outside Japan, but company representatives have already said the the i-MiEV is scheduled to be sold in North America.

1. Principal product features
(1) Zero drive-time CO2 emissions
The i-MiEV is a zero-emissions vehicle (ZEV) which produces no CO2 emissions while being driven. Even when the CO2 gas emitted at power generating stations is taken into consideration, the i-MiEV generates approximately one-third of the CO2 produced by the gasoline “i” minicar (Calculated in-house based on the average of electric energy frameworks in Japan).
(2) Driven 100% by electrical power
The i-MiEV is very economical because it only uses electrical energy as its power source. Also, depending on electric power company rate fees, the running cost can be reduced further by charging the battery when off-peak (late night) rates apply*5.
|*5 ||An application must be submitted to the electric power company to qualify for domestic late night rates. |
(3) Quiet, agile, comfortable performance
The i-MiEV delivers the quiet and comfortable motoring experience only possible from an internal combustion engine-less EV. Maximizing the excellent response and high low-end torque inherent to its electric motor i-MiEV enables a level of responsive and powerful performance that surpasses that of the gasoline-powered turbo engine “i” minicar.
(4) Ample range for everyday minicar use
The i-MiEV has a single-charge range of 160 km*6 in the Japanese 10-15 mode urban driving pattern. This gives it a range that is ample*7 for everyday minicar use.
|*6 ||Actual range will vary depending on weather conditions, road congestion and on how the driver operates his vehicle (use of accelerator, climate control system, etc.) |
|*7 ||A nationwide survey in Japan indicates that on average 90% of car drivers cover less than 40 km/day on weekdays and that 80% cover less than 60 km/day at weekends and holidays (in-house research). |
(5) 3 ways to charge the battery
The i-MiEV uses a 3-way charging system that allows the drive battery to be charged at home or when out and about. For normal charging i-MiEV is connected to either a standard 100-volt or 200-volt domestic outlet using the charging cables supplied with the vehicle. The i-MiEV‘s battery can also be “quick charged” at quick-charge stations which are currently being established throughout Japan.

2. Advanced technology
(1) Main powertrain components
a. Drive battery
The i-MiEV is powered by a very high energy-density lithium-ion battery manufactured by Lithium Energy Japan*9. The large-capacity drive battery is comprised of 88 lithium-ion cells connected in series and is installed under the floor in the center of the vehicle. This configuration contributes to outstanding handling and stability due to the car’s low center of gravity.
|*9 ||Joint venture established on December 12, 2007 between Mitsubishi Motors, GS Yuasa Corporation and Mitsubishi Corporation to develop, manufacture and sell large-capacity and high energy-density lithium-ion cells for EV use. |
b. Motor (power unit)
The i-MiEV uses a high-efficiency compact and lightweight permanent magnet synchronous electric motor specially developed for the vehicle. It generates maximum torque from low engine speeds to deliver powerful response and a comfortable ride experience. When the vehicle slows down the regenerative brake system causes the motor to operate as a generator. The electrical energy recovered is stored in the drive battery.
The i-MiEV uses a lightweight and compact single-speed reduction gear transmission, exploiting the high low-end torque inherent to the electric motor and eliminating the need for complex gear shifting mechanisms as found in internal combustion engine powered vehicles.
d. On-board charger
The i-MiEV comes with a compact, lightweight on-board charger that allows the drive battery to be charged using a domestic 100V/200V AC line.
e. DC/DC converter
The DC/DC converter is used to charge the 12-volt auxiliary battery and power electrical equipment. It is integrated with the on-board charger in a single unit to reduce size and weight.
The i-MiEV ‘s motor is driven by an alternating current. The inverter converts high-voltage direct current from the drive battery to alternating current and supplies motor with the power required to drive the vehicle.
(2) Combination meter display
The combination meter instrument cluster is comprised of a power meter that presents a visual display of power consumption and energy recovery status, a drive battery residual charge indicator that indicates how much remaining power there is left in the drive battery, and an available range indicator that displays an estimate of how far the vehicle can be driven on the basis of average power consumption over the last few kilometers.
(3) Shift selector
The shift selector provides the three positions described below that allow the driver to choose between maximum fun, maximum economy or maximum regenerative brake bias.
| D-position: ||Generates gutsy torque in direct response to accelerator input and allows the driver to enjoy i-MiEV ‘s performance potential to the maximum. |
| Eco-position: ||Reduces power output and consumption to deliver maximum economy. |
| B-position: ||Increases the regenerative brake bias. Power output is the same as for D. |
(4) Climate control
The i-MiEV ‘s climate control system features air conditioning with an electrically powered compressor and a heating system which circulates warm water heated by an electric heater. The control dial provides six-step manual adjustment of both cooling and heating temperatures. The system reduces power consumption by minimizing occasions when both cooling unit and the heater operate together.
(5) Safety features
a. Drive battery protected by sturdy frame
The high-voltage system, battery pack included, is located inside the body frame and is further protected by a well-crib frame against damage from any direction of impact.
b. Integrated vehicle management system: MiEV OS
The MiEV OS (MiEV Operating System) gathers data and information from all the major EV components to provide integrated management of the i-MiEV ‘s performance. The advanced management system constantly monitors battery status and the energy recovered from the regenerative brakes while regulating output to ensure smooth and powerful acceleration from a full stop. As a result the system optimizes and minimizes energy consumption while delivering road performance that is comfortable, safe and reassuring.
3. Other equipment and trim
(1) Body colors
The range of 8 body finishes includes monotones and two types of 2-tone color schemes.
Three monotone colors are offered: White Solid, Cool Silver Metallic and Raspberry Red Pearl (factory option).
b. 2-tone schemes (factory option):
| Type A: ||The two 2-tone color schemes that have been used to date to highlight the i-MiEV ‘s originality are available: Red Solid / White Solid and Cool Silver Metallic / White Solid. |
| Type B: ||In addition two new 2-tone color schemes are available. – “Clean image:” White Pearl / Ocean Blue Metallic and White Pearl / Mint Green. – “Premium image:” Cool Silver Metallic / Black Mica. |
(2) LED headlamps and rear combination lamps
The i-MiEV is the first minicar*10 and the first Mitsubishi Motors model to use LED headlamps, which throw a longer and wider low-beam pattern while also cutting power consumption. The rear combination lamps also use fast-illuminating LED emitters for the tail and stop lamps, making these lamps more instantly visible to following vehicles.
|*10 ||As of end May 2009, according to Mitsubishi Motors research. |
(3) PBS-bamboo fiber Green Plastic tailgate trim
The i-MiEV uses PBS (polybutylene succinate)-bamboo fiber Green Plastic for the tailgate interior trim. The use of PBS-bamboo fiber cuts life-cycle emissions (from extraction of raw materials to final disposal of product) of CO2 by some 10 percent compared with polypropylene.
(4) Mitsubishi Multi-Entertainment System (MMES)
The i-MiEV is available with the Mitsubishi Multi-Entertainment System (with a 7-inch display and SSD navigation) that is built around solid state drive (SSD) technology to offer outstanding power saving and shock resistant properties. MMES is a factory-fitted option. The navigation database can be updated using SD flash cards and the company plans to use this feature to display the location of battery charging stations as they become available.
