The journey has begun to a new world where cars are clean
and quiet, and i-MiEV is leading the way. 100% electric, yet offering
surprising power and a smooth, quiet ride, i-MiEV is redefining the way
the world drives.
The Future
i-MiEV. Experience the future of motoring today
Engineered to be the perfect car for the urban
environment, the i-MiEV can park in the tightest spaces, breeze through
traffic like a dream and can still comfortably accommodate four adults.
Over 3,000 i-MiEVs have been sold worldwide and
in the UK it has been involved in official government trials since
mid-December 2009.
Testing the i-MiEV against typical UK urban usage has proved the benefits are real:
Costs just £376 to charge for 12,000 miles
driving (£2.91 per full charge based on an average of 14.39p per kWh).
If you are using the Economy 7 tariff then the cost for 12,000 miles
could be as little as £223 (£1.73 per full charge based on an average of
8.54p per kWh)
Low servicing costs and downtime – only 4 major working parts compared to over 300 in a typical internal combustion engine
The i-MiEV Mitsubishi Service Plan (MSP) covers the first three years servicing at a cost of just £300
Servicing carried out by any one of Mitsubishi's 133 service dealers
Exempt from road tax
First year capital allowances for fleet vehicles
Zero benefit-in-kind company car tax
Exempt from London Congestion Charge
Free parking in some London boroughs and cities such as Milton Keynes
5 year battery warranty and 3 year vehicle warranty
i-MiEV will fully charge in approximately 7 hours
at a typical cost of £2.91 (£1.73 using Economy 7). Fully charged
i-MiEV will drive up to 93 miles. Maximum range of 93 miles will vary
with load, road conditions, driving style and other factors.

i-MiEV Technology
Motor
The AC synchronous permanent magnet motor
develops 49kW (66bhp) and a high 180Nm (133 lb.ft) of torque - but
importantly all of the latter is available instantly, from 0rpm right up
to 2,000rpm, enabling the i-MiEV to easily keep up with city traffic.
The motor continues to pull strongly beyond 2,000rpm ensuring a relaxed
driving experience.
Transmission
The motor’s high torque output and ability to
spin to 8,000rpm means no gear changes are necessary, and the single
gear ratio (6.066:1) delivers optimal performance. The transmission
includes a conventional differential but no reverse gear is required
since the motor spins in the opposite direction when R (Reverse) is
selected via the gearshift.
Traction Battery
The traction battery pack, located below the
i-MiEV’s floor, consists of 88 lithium-ion 3.7V/50Ah cells connected in
series to deliver 330V/16kWh, and powers the electric motor (via the
inverter), air conditioning and cabin heater. Other devices are powered
by a conventional 12V auxiliary battery, charged by the traction battery
via a DC-DC converter integrated with the on-board charger. Safety
features include a cell monitoring device, electrical leakage detector
and a very strong protective casing.
Inverter
The inverter unit converts the traction battery’s DC output voltage into a 3-phase AC supply required by the electric motor.
On-board Charger
Battery charging from a normal domestic
electricity supply is achieved via an on-board charger which converts
mains AC voltage to a suitable charging voltage for the traction
battery. A full charge from at or near empty can be achieved in around 7
hours. i-MiEV is supplied with a dedicated 5-metre domestic charging
cable (N.B. A conventional extension cable must never be used!) The
normal charging socket is located on the rear right-hand side of the
vehicle.
Rapid Charging
If access to a rapid charging point is
available, i-MiEV can be charged from empty to 80% in as little as 30
minutes. The rapid charging socket is located on the rear left-hand side
of the vehicle, and is designed to be compatible with the standardised
connector on the end of the rapid charging unit's heavy-duty cable.
Driving Modes
When the accelerator is released the vehicle
will slow down due to the regenerative braking effect - under this
condition the inertia of the vehicle turns the motor into a generator
which momentarily recharges the traction battery. i-MiEV has three
driving modes, marked D, B and C on the gearshift panel. D mode is for
urban driving, tuned to be energy efficient; B mode increases
regenerative braking during downhill driving; C mode decreases it for
smoother driving characteristics on longer runs.
Energy Usage Indicator
The large central display includes an array
of conventional warning lights, a large central digital speedometer and
the semi-circular Energy Usage Indicator - keeping the needle within the
green ’Eco’ zone as much as possible while driving extends the usable
range. Releasing the accelerator initiates regenerative braking which
moves the needle into the blue ‘Charge’ zone.
Energy Level Gauge
Range Remaining Display
Pressing a button scrolls the small circular
screen to the right of the main display through milometer, trip A, trip
B, illumination control, service reminder (in miles and months
remaining) and range remaining on current traction battery charge level,
which is calculated on energy consumption over the last 15 miles and
air conditioning usage.
ABS with EBD
Lateral slippage can easily occur if the rear
wheels lock up due to braking hard on slippery surfaces or braking hard
when at high speeds. ABS suppresses this by controlling the brakes’
hydraulic pressure. EBD adjusts the rear wheels’ braking force to the
number of occupants and load to deliver braking force that is ideally
matched to almost any situation.
M-ASTC
Active Stability Control -
If sensors located throughout the car detect unstable movement, such as
lateral slippage, the Stability Control function automatically controls
the brakes and motor torque to stabilise the car. Traction Control - If the
sensors detect wheel slip when starting on slick surfaces, such as a
snow-covered road, the Traction Control function automatically brakes
the slipping wheel and governs motor torque to enable a smoother start.
Unlike other vehicles it also functions while decelerating, to improve
stability during regenerative braking.
Suspension
The i-MiEV adopts a MacPherson strut design
for its front suspension which, assisted by a stabiliser bar, provides
excellent on-road handling characteristics. The rear suspension employs a
3-link de Dion system. The traction battery position also provides
i-MiEV with a low centre of gravity for stable cornering performance.
Six Airbags
To keep occupants in every seat safe in the
event of a collision, the i-MiEV is equipped with a 6-airbag system to
provide protection from all sides. Curtain airbags extending along both
sides protect front and 2nd-row occupants in a side collision, while the
1st-row occupants are additionally protected by front and side airbags.
