2012 Nissan LEAF™ A New Era of Mobility Continues With No-Compromise
Performance, Best-in-Class Combined MPG Equivalency Rating of 99 MPG
The
2012 Nissan LEAF™, the world's first affordable, zero-emission car, continues in
its second year of production to lead the drive into the "no gas, no tailpipe"
zero-emission era. Designed specifically for a lithium-ion battery-powered
chassis, the Nissan LEAF is a medium-size hatchback that comfortably seats five
adults and has a range of 100 miles (U.S. LA4 cycle) on one full charge to
satisfy real-world consumer requirements.
Enhancements for the 2012
model year include the addition of a standard battery heater, heated steering
wheel, heated front and rear seats, heated outside mirrors and rear HVAC duct on
all models. Also, a Quick Charge Port is now standard on the LEAF
SL.
Best-in-Class MPG Equivalency Rating, Numerous First Year
Awards
The Environmental Protection Agency (EPA) has rated the
Nissan LEAF as "best" in the mid-size vehicle class for fuel efficiency and
"best" for the environment with a 99 miles-per-gallon (MPG) equivalency rating
(combined city/highway), along with a rating of 106 MPG city and 92 MPG highway.
The MPG equivalency rating was developed by the EPA as a way to provide
a standard so consumers can compare vehicles across the spectrum and make an
educated purchase. The calculation is based on the EPA's formula of 33.7kW-hrs
being equivalent to one gallon gasoline energy based on five cycle tests using
varying driving conditions and climate controls. The vehicle was also rated
best-in-class for the environment based on emitting zero greenhouse gases or
other traditional tailpipe emissions.
Nissan LEAF was also named "2011
World Car of the Year," edging out the BMW 5-Series and the Audi A8 for the top
spot. The award is just one of a string of accolades for the vehicle, which was
also named "2011 European Car of the Year."
In addition, Nissan LEAF's
100-percent electric, zero-emission drive system is included on Ward's Auto
World magazine's prestigious "10 Best Engines" list for 2011. It is the first
time in the 17-year history of the magazine's "10 Best Engines'" that the
selection committee has chosen a power system which doesn't have an engine and
will never burn a drop of gasoline.
Nissan LEAF was also chosen as one
of the 2011's "10 most transformative products" by a panel of experts in
addition to members of the Popular Mechanics magazine's editorial board of
advisers.
"Transformative is a great word when describing Nissan LEAF.
Consumers do not want to compromise on space, driving enjoyment or technology
features, regardless of a vehicle's power source," said Al Castignetti, vice
president and general manager, Nissan Division, Nissan North America, Inc.
(NNA). "We've developed the Nissan LEAF to offer stimulating acceleration
performance and a quiet, refined interior with the latest amenities and room for
five adults while still carrying cargo - all in a vehicle that is totally
electric, produces zero carbon emissions while driving and has 100 miles of
range."
A Dedicated EV Platform, Innovative Battery
Design
The front-wheel drive Nissan LEAF utilizes a dedicated EV
platform with batteries housed in the floor for optimum vehicle packaging and
weight distribution. The highly rigid body design includes a rigid-mounted
battery frame, which helps provide greater body rigidity compared to a
conventional compact car. LEAF rides on a 106.3-inch wheelbase, with a
175.0-inch overall length, 69.7-inch width and 61.0-inch height. Dimensionally,
the Nissan LEAF falls in between the Nissan Altima and Nissan Versa, and like
those vehicles provides room for five adults and a good-sized cargo area.
Placing the batteries in the floor of the vehicle provides optimum weight
distribution to help enhance handling and allows for five-passenger seating by
not intruding into the cabin space.
Nissan LEAF's 24 kWh lithium-ion
(Li-ion) battery is comprised of 48 compact modules of four cells each, which
allows a high degree of packaging flexibility. The batteries are designed to
maximize drive time and minimize charging time. The battery was developed by the
Automotive Energy Supply Corporation (AESC), a joint venture of Nissan and NEC.
Unlike conventional cylindrical batteries, the thin, compact laminated cells
offer more flexibility in design applications.
The battery powers a
high-response 80kW AC synchronous motor, rated at 107 horsepower and 207 lb-ft
of torque, which drives the front wheels through a single speed reducer. Unlike
a conventional internal combustion engine, Nissan LEAF delivers 100% of its
torque from start, delivering smooth, consistent acceleration and the driving
feel similar to a conventional V6 engine.
Range is rated at 100
miles/charge based upon US EPA LA4 City cycle conducted in laboratory tests.
(Battery capacity decreases with time and use; actual range will vary depending
upon driving/charging habits, speed, conditions, weather, temperature, and
battery age.)
The Nissan LEAF offers a number of charging options. A
charge port is located in the front body for the 200V charger and portable
trickle charge cable (110V). The available Quick Charge Port (standard on SL)
allows charging to 80% capacity in 30 minutes at public charging stations.
There's also a standard photovoltaic solar panel spoiler on SL models, which
supports charging of the 12-volt battery for car accessories.
The Nissan
LEAF utilizes an independent strut suspension with stabilizer bar in front and a
torsion beam rear suspension with integrated stabilizer bar. Responsive steering
is provided by a vehicle-speed-sensitive electric power steering system. Braking
is provided by power-assisted front vented disc/solid rear disc brakes with
Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and
Brake Assist (BA). "Nissan LEAF steers, brakes and handles like a 'real' car
because except for the engine, fuel tank and exhaust, it essentially is one,"
said Castignetti. "The Nissan LEAF does have an advantage in that braking force
is used to re-power the battery, rather than wasting it like in a traditional
vehicle."
Nissan LEAF's standard regenerative braking system helps
increase range. By applying the brakes or reducing speed by letting off the
accelerator, the electric motor acts as an electric generator, converting energy
that would otherwise be wasted into battery energy. To increase regenerative
braking, there's a driver-controlled Eco mode setting, which can also be used to
reduce air conditioning and thus improve driving range when driving in urban
areas.
Because Nissan LEAF does not have an internal combustion engine,
Nissan has incorporated an "Approaching Vehicle Sound for Pedestrians" system,
which is designed to alert pedestrians that a vehicle is approaching. When
driving at low speeds, the system emits a sound from a speaker at the front of
the vehicle. When the vehicle's speed reaches 19 mph, pedestrians are able to
hear the car moving and the "approaching sound" automatically turns off. If the
vehicle speed drops below 16 mph, the sound comes on
again.
Exterior Designed for "Smart Fluidity"
Nissan
LEAF's dedicated EV body is designed to offer "smart fluidity" - a fusion of
sophisticated aerodynamic management and aerodynamic acoustics with the freedom
provided by the new EV layout. The smooth, elegant movement of the body starts
from the low, compact hood, moves through the iconic shoulder character line and
on toward the large rear spoiler.
The distinctive exterior styling is
characterized by sharp, upright V-shaped design featuring long, up-slanting LED
headlights with a blue internal reflective appearance. The headlights split and
redirect airflow away from the door mirrors, reducing wind noise and drag. The
headlights also consume about 50 percent of the electricity of conventional
halogen headlights. Heated outside mirrors have been added for 2012.
In
the rear, the slim-type aerodynamic LED taillight design and crisp corners
combine with the aerodynamic muffler-less rear bumper with rear diffuser to
manage the aerodynamics of the rear end without compromising rear interior
roominess. The coefficient of drag is just 0.29.
The exterior also
utilizes a flat underbody (including a large front flat floor cover, motor area
undercover, front undercover and rear diffuser with fins) to help manage airflow
under the vehicle. An innovative vortex-shedding roof-mounted antenna is one of
many design elements utilized to help reduce wind noise. Other noise reduction
features include a quiet-operation windshield wiper motor, a sound insulation
windshield design and a dual-isolated motor-mounting system.
"Because the
operation of the Nissan LEAF powertrain itself is so quiet, the engineers paid
extra attention to management of wind noise in the exterior design, since it
would be more noticeable than with a traditional internal combustion vehicle,"
explained Castignetti.
Nissan LEAF's charging point is hidden under a
small door located in the front of the vehicle. The 5-door hatchback design also
features chrome door handles, aerodynamic outside mirrors and a large greenhouse
to provide a bright interior environment. Attractive 5-spoke 16-inch
aluminum-alloy wheels mounted with P205/55R16 Bridgestone Ecopia tires are
standard. Five exterior colors are available for 2012: Glacier Pearl, Blue
Ocean, Brilliant Silver, Super Black and Cayenne Red.
Distinctive
"EV Touch" Interior
The roomy Nissan LEAF interior offers a
pleasingly modern design created to provide a unique "EV touch" with "simple and
human flow." The bright, welcoming atmosphere starts with the wide, high tech
instrument panel design - which is dominated by a twin combination meter display
in front of the driver and a center "floating" piano black C-stack with a 7-inch
information display.
The digital "eyebrow" display at the top of the
instrument panel provides high visibility for the Eco indicator and speedometer,
while the lower liquid crystal meter display houses the power meter, battery
temperature gauge, multi-function display, remaining energy gauge, capacity
level gauge and distance to empty display.
The flat panel center C-stack
cluster continues the "EV touch" feel with the color monitor for the standard
navigation system, available RearView Monitor and control of the audio and
climate systems.
The display also provides access to the CARWINGS
telematics system, which is connected to a global data center, (subscription
required, no charge for 36 months). Through CARWINGS, Nissan LEAF drivers are
able to use mobile smart phones to turn on air conditioning and set charging
functions remotely, even when the vehicle is powered down. The system also
displays "reachable area," as well as showing a selection of nearby charging
stations. An on-board charging timer can also be programmed to start the
charging event whenever desired.
The Nissan LEAF interior also includes
comfortable heated front bucket seats and a 60/40 split folding heated rear seat
and rear HVAC duct. The seat fabric is made with partially recycled materials.
Recycled materials are also used for the back door trim, roof trim and
headliner, carpeting and a number of other interior pieces such as the door
panels and center console storage cover.
The center console area includes
the palm shifter (inspired by a PC mouse) for the "by wire" drive selector. The
3-spoke heated steering wheel houses controls for the cruise control, audio
system and standard Bluetooth® Hands-free Phone System. XM® Satellite Radio (XM®
subscription required, sold separately) is also standard, with HomeLink®
Universal Transceiver standard on Nissan LEAF SL models. One interior color is
offered, Light Gray.
Five Star Safety Rating
The
100-percent electric Nissan LEAF has earned a 5-star overall vehicle rating for
safety as part of the National Highway Traffic Safety Administration's New Car
Assessment Program (NCAP). Nissan LEAF is the first fully electric vehicle to
earn this highest distinction from the program. Starting with 2011 models, NHTSA
introduced tougher tests and requirements in order to earn 5-star ratings.
The Nissan LEAF has also been named a "Top Safety Pick" by the Insurance
Institute for Highway Safety (IIHS), the first 100-percent electric vehicle to
do so. The rating is given to vehicles that achieve the Institute's highest
rating of "Good" in front, rear and side impact protection as well as being
equipped with electronic stability control and earn a good rating in roof
strength.
Standard Nissan LEAF safety systems include Nissan Advanced Air
Bag System (AABS) with dual-stage supplemental front air bags with seat belt
sensors and occupant classification sensor, front seat-mounted side impact
supplemental air bags, roof-mounted curtain side impact supplemental air bags
