ENHANCED
SAFETY AND CONVENIENCE MAKE GMC YUKON AND YUKON XL EVEN BETTER
TRANSPORTATION CHOICES FOR 2005
Families love
GMC Yukon and Yukon XL because they deliver extraordinary roominess,
along with plenty of comfort and entertainment choices. For 2005,
GMC’s lineup of Professional Grade full-size sport utilities
also delivers even more of what families demand from their vehicles:
increased safety features, including the availability of StabiliTrak
(including the G80 locking differential) for every model and a
standard enhanced passenger safety belt reminder, which provides
a repetitive, progressively strident message to any unbuckled
front seat occupant, as a reminder to fasten safety belts.
"Agility and
comfort, along with exceptional roominess, have always been the
cornerstones of the Yukon family's success," said Craig Bierley,
GMC product director. "This year, we also enhance safety and convenience
factors by making StabiliTrak available on all Yukon and Yukon
XL models, as well as offering a DVD-based touch-screen navigation
system."
StabiliTrak,
Quadrasteer enhance driver control
GM’s
StabiliTrak stability enhancement system – previously available
only on select Yukon models – assists the vehicle in maintaining
the driver’s intended path by applying a brake force at
any corner of the vehicle independent of the driver’s use
of the brake pedal. StabiliTrak uses an accelerator pedal position
sensor, a brake master cylinder pressure sensor and a steering
wheel angle sensor as inputs to interpret the driver’s desired
path and whether to accelerate or decelerate the vehicle. StabiliTrak
also uses these sensors plus a lateral accelerometer and yaw rate
sensor to determine the vehicle’s actual path. Yukon and
Yukon XL models equipped with StabiliTrak also receive the G80
locking differential.
If the difference
between the driver’s desired path and the vehicle’s
actual path becomes great enough, StabiliTrak takes appropriate
action to assist the driver with maintaining the desired path.
If the vehicle begins to “snowplow,” or understeer,
StabiliTrak applies the inside rear brake to help turn the vehicle.
If the vehicle begins to fishtail, or oversteer, StabiliTrak applies
the outside front brake to straighten the vehicle. StabiliTrak
is integrated with the traction control and ABS systems.
On two-wheel-drive
models, traction is controlled by transferring torque across the
rear axle (rather than all differentials on 4WD models) to whichever
rear wheel has the most traction. In four-wheel-drive models,
drivers get full StabiliTrak benefits in 4AUTO. StabiliTrak can
be partially turned off in 4AUTO and on two-wheel-drive models
and still provide partial yaw stability and traction control,
plus full ABS control. Only the engine management is deactivated,
allowing drivers to freely spin the vehicle’s wheels when
in deep snow, sand or gravel. In four-wheel-drive models, selecting
4LO completely shuts off StabiliTrak, creating a low-gear ratio
with extra torque for better hill climbing, towing a boat up a
launch or controlling vehicle speed for descents down steep declines
without constant use of the brakes.
Yukon XL continues
to offer the segment-exclusive Quadrasteer four-wheel steering
system. It is available on Yukon XL 2500 models with either two-wheel-
or four-wheel-drive. The Quadrasteer four-wheel-steering system
offers low-speed maneuverability and high-speed stability, handling
and control ideal for pulling a trailer. At low speeds, Quadrasteer
enables the rear wheels to turn in the opposite direction of the
front wheels. That helps the vehicle make tighter turns such as
when cornering or getting into a tight parking space. At higher
speeds, the system reduces vehicle yaw, or rotational motion,
for more control during lane changes and demanding conditions.
In the Yukon
XL, Quadrasteer reduces the turning circle from 44.3 feet (13.5
m) to 36.5 feet (11.1 m).
Enhanced
touch-screen navigation radio
Also new to
Yukon and Yukon XL models for 2005 is an available DVD-based touch-screen
navigation radio. The easy-to-use system employs touch-screen
functionality and will map routes with 2-D and 3-D full-color
map views on a large, 6.5-inch (165-mm) display screen. Once the
navigation DVD is inserted and the address entered on the system's
screen, a route map is generated and audio commands are provided.
Instructions in English and French are available.
The verbal
commands tell drivers when to turn and alerts them if they stray
from the calculated route; the system automatically recalculates
a new route from their current position if they make a wrong turn.
Additionally, drivers can instruct the navigation system to plan
a route using the shortest path or one using major roads.
Improved
fuel economy
Already a
class leader in fuel economy, the 2005 Yukon and Yukon XL extend
that leadership with three enhancements that lead to approximately
a 1-mpg fuel economy improvement.
Electric
cooling fans
This model
year’s Yukon and Yukon XL models feature an all-electric
cooling system (compared to fan and fan clutch on 2004 models).
The all-electric cooling system consists of two 200-watt electric
fan packages and an improved dissipation radiator. The new cooling
system provides a number of advantages:
-
A reduction
in parasitic losses due to disengaged fan speed with a corresponding
increase in combined city/highway fuel economy
-
A significant
improvement in idle air conditioning performance (driver/passenger
comfort) as well as an ability to idle with the air conditioning
on for extended periods in very high ambient temperatures
-
Quieter
operation
Regulated
voltage control
A new voltage
control system monitors the battery’s charge status and
controls the vehicle’s generator to minimize parasitic voltage
loss.
Aerodynamic
improvements
Other changes
designed to improve fuel economy include improved sealing of the
vehicles’ front end. For example, tow hook openings are
now sealed when not ordered on the vehicle. In addition, the center
hole in the front air deflector has been sealed, an extension
has been added to the front air deflector, and the aerodynamics
for the running boards have been improved.
Additional
changes
Yukon and
Yukon XL’s other content changes for 2005 include:
-
17-inch
wheels: Ultra Bright Polished 17-inch cast aluminum wheels –
an all-new appearance – are offered as a stand-alone option
for 2005.
-
New exterior
colors: Yukon and Yukon XL are available in two new colors for
2005: Sand Beige Metallic and Blue-Green Crystal.
-
OnStar
with sixth-generation hardware: OnStar-equipped Yukon and Yukon
XL models feature new sixth-generation hardware with digital
and analog coverage. OnStar’s Gen 6 hardware also includes
upgraded hands-free voice recognition capabilities including
more intuitive continuous digit dialing and improved voice recognition
accuracy. OnStar is the leading provider of in-vehicle safety,
security and information services in the United States and Canada.
Using the GPS satellite network and wireless technology, OnStar
features core safety services and OnStar Personal Calling that
allows drivers to make and receive hands-free, voice-activated
phone calls using a powerful three-watt digital/analog system
and external antenna for greater reception.
