XTRONIC CVT
The
CVT
(Continuously
Variable
Transmission)
provides
smooth
and
"stepless"
ratio
changes,
unlike
conventional
transmission
systems
that
use
sets
of
fixed
gears.
Nissan
appreciated
the
CVT's
benefits
of
fuel
economy
and
seamless
acceleration
from
an
earlier
stage,
and
was
the
world's
first
to
offer
CVTs
for
engine
displacements
as
large
as
3.5
liters.
Today,
Nissan's
CVT
technology
offers
smooth
and
fuel-efficient
"fun-to-drive"
performance
in
an
extensive
range
of
Nissan
models,
from
the
compact
class
all
the
way
up
to
high-powered
luxury
vehicles.
CVT for 3.5-liter class engine
Seamless acceleration
The CVT is an automatic transmission that uses two pulleys with a steel belt running between them. To continuously vary its gear ratios, the CVT simultaneously adjusts the diameter of the "drive pulley" that transmits torque from the engine and the "driven pulley" that transfers torque to the wheels. With stepless shifting of gear ratios, the CVT can avoid the shift-shock and deliver smooth driving, making it an exceptional transmission solution.
In the XTRONIC CVT, the gear ratio range* from low to high gear is expanded, attaining a top-of-class final gear reduction ratio of about 6, thanks to pulley and steel belt improvements and the use of high performance ATF (Automatic Transmission Fluid). This ratio spread is among the world's widest for a CVT designed for use with 1.5-liter to 2.0-liter class engines. With a wide ratio spread and highly precise control, the CVT delivers outstanding acceleration and fuel economy.
Expanded gear ratio range
We improved the electronic control system and the hydraulic system components under its control. In addition, adoption of a high-performance ATF (Automatic Transmission Fluid) enhances response and stability. As a result, the CVT shifts ratios about 30% faster than the previous version. With this, Nissan's CVT technology provides instantaneous response to the driver's intention, in addition to a natural feeling of powerful acceleration.
