Nissan's Pivo concept car explores
further potential for future electric vehicles, starting
from its cabin that revolves 360 degrees. No need to

technology and navigation and audio systems that are
simple to operate while driving. These features are
supported by Nissanís environment-friendly technologies
such as the Compact Lithium-ion Battery.
Obviously, Pivo is an urban car par
excellence. It can pass oncoming traffic even on the
narrowest streets as it can find its parking space in the
tightest of spots. It seats three passengers despite an
overall length of just 2,700 mm - roughly the wheelbase of
an upper medium, D-segment passenger car.
The driver sits front and center with
two passengers side-by-side in the rear. Tall,
electrically-powered sliding doors make it easy to get in
and out. With Pivo, thereís no going back for parking;
the entire cabin pivots Ė as the conceptís name
Pivo, because it pivots: parking without
This ability to park while always
looking forward is enabled by Nissan's advanced
drive-by-wire technologies that preclude the need for
mechanical connections between cabin and chassis.
Easy to operate with no hidden dangers
or distractions, Pivo manages the flow with a host of
telematics features that deliver the right information at
the right time. The driver can control the information
flow without taking the eyes off the road. Whatís more,
visibility is enhanced by see-through pillars, Nissan's
Around View Monitor and other innovations that reduce
Front and rear lamps feature a clear,
clean-looking design. The exterior even features oval
recesses both front and rear that are covered with soft
materials Ė comfy places to sit outside when Pivo is
parked. You find the same thoughtfulness in a soft,
organic interior that extends from the center of the
revolving egg-shaped cabin, which is the Pivo's most
Because the platform has a
longitudinally symmetrical design, the driver's perception
of the car's corners does not change even when the
cabin is rotated 180 degrees.
Technologies - Pivo is powered
by a Nissan-developed high-performance Compact
Lithium-ion Battery and Nissanís unique Super Motor.
The result is zero emissions.
The electric powertrain enables a
highly compact body. Nissanís Compact Lithium-ion
Battery Ė which, being flat, requires much less space
than conventional cylindrical cells Ė to achieve
remarkable packaging efficiency.
Even more space and weight savings are
achieved with Nissanís Super
Motor. One Super Motor on each axle
delivers power to two shafts, each of which can be
controlled independently. This allows efficient
distribution of torque to all four wheels with two (not
four) electric motors.
Pivo's unique revolving cabin is just
one of the myriad possibilities enabled by Nissanís
multiple drive-by-wire technologies. These include steer-by-wire,
brake-by-wire and shift-by-wire systems that
replace mechanical linkages with electronic signals.
By eliminating the need for mechanical
links between cabin and chassis, designers were able to
create the unique pivoting passenger compartment.
Drive-by-wire technologies afford even
more flexibility inside the cabin as the layout of
steering, braking and other functions is no longer
governed by mechanical linkages. Even better,
drive-by-wire systems mean less weight and fewer
See-through pillars and Nissanís
Around View Monitor
helps to reduce dangerous blind spots. Cameras mounted on
the outside of each A-pillar feed an accurate image of the
surroundings to screens mounted on the inside of the
The net effect is pillars that become
virtual windows. The Around View Monitor meanwhile
generates a 360-degree view of the carís
surroundings on a dashboard monitor. Cameras positioned
front and rear on both sides of the car capture images of
the surroundings. An innovative image processing technique
synthesizes these images into a single birdís-eye view.
A dash-mounted infrared (IR) commander
allows drivers to operate the navigation system and audio
system without taking an eye off the road or fumbling
around for controls. Itís a new type of human-machine
interface (HMI) that uses an infrared camera and
Nissanís "Magic 4" concept. You simply point
fingers at the infared commander to choose from any of
four items on a menu. If you want item number three, hold
up three fingers. Or, for example, if you want the music
louder, just motion upwards with your hand.
Thanks to Nissan's Horizontal
Display there is even less need to take an eye off the
road Ė because information is displayed along the bottom
of the windshield. This system, first featured in the Serenity
concept shown at the Tokyo Motor Show two years ago,
displays information in the manner of movie subtitles.
This innovative display system supports Nissan's future
telematics interface concept.
For example, in ďCity Browsing mode,Ē
the system can display information transmitted live from
Whatís that building up ahead? City
Browsing labels it.
What does the future have in store?
Pivo points the way.
