Description:
The newly introduced 1998 Lincoln
Navigator plots a fresh course by merging the
comfort and luxury of a premium sedan with the
go-anywhere ability of an advanced fullsize sport
utility vehicle (SW).
Navigator
was designed and engineered to satisfy customers
who have expressed a desire for luxury and
comfort, safety, space for up to eight passengers
or a week's worth of adventure gear, power,
performance, towing capability and a quiet ride.
Sport
utility vehicles are the fastest growing segment
of the U.S. automotive market. By the end of this
year, SW sales likely will account for 2.3
million vehicles or 16 percent of the total
market. Within this segment, the strongest
expansion is in the full-size category, expected
to grow to a half-million units by the end of
1998.
In
just 23 months--from design approval to Job
One--Navigator was engineered to be the first
full-size SW capable of combining deep-seated
luxury and uncompromised function. Navigator
efficiently fits in a standard-size garage.
Instead
of reinventing the wheel, the Navigator
engineering team began with the successful Ford
Expedition platform introduced for sale for the
1997 model year. Key attributes included
box-section frame rails running from the front of
the vehicle to about the rear-axle centerline, a
coilspring short- and long-arm (SLA) front
suspension, speed-sensitive power steering, a
state-of-the-art SOHC V-8 powertrain, and
best-in-class towing capacity of up to 8,000
pounds.
Standard
Navigator equipment includes a 5.4-liter SOHC
V-8, 2x2 rear load-leveling suspension,
four-wheel disc brakes with four-wheel
antilock-braking system, special shock-absorber
tuning, tires unique to Navigator, a distinctive
Lincoln exterior appearance, and a luxurious
interior.
Navigator's
5.4-liter SOHC V-8 engine is an outgrowth of the
original modular V-8 that made its debut in the
1991 Lincoln Town Car. Core features are a
deep-skirt cylinder block with cross-bolted
main-bearing caps, long cylinder-head retention
bolts threaded into the most robust area of the
block, a forged-steel crankshaft with
induction-hardened journal surfaces,
cast-aluminum cylinder heads, a chain-driven
single-overhead cam valvetrain with roller-type
cam followers and hydraulic lash adjusters,
powdered-metal connecting rods with a cracked
cap-to-rod interface engineered for optimum
alignment, all-aluminum connecting rod and main
bearing inserts for maximum durability, and
rubber-isolated cam covers to minimize radiated
engine noise. An innovative dual-volume intake
manifold plenum is equipped with a
computer-controlled valve to provide two small
induction chambers at low engine speeds and one
large chamber at high speed. The lower portion of
the intake manifold is plastic for thermal
isolation. Long intake runners are tuned to boost
low-rpm output.
The
Navigator's V-8 is engineered for low maintenance
and high reliability. Its fail-safe cooling
system permits the vehicle to continue running at
reduced speed for a short distance after total
cooling loss with no permanent engine damage.
When the engine control computer detects a
precipitous rise in coolant temperature, it
commands cylinders to fire alternately only half
produce power while the other half pump cooling
air through the engine. A six-quart oil pan
provides extra lubrication reserve, longer life
for internal components, and a hedge against high
engine operating temperatures. Under normal
driving conditions with regular oil and filter
changes at 5,000-mile intervals, Navigator needs
no additional tune-up service for the first
100,000 miles.
Navigator's
5.4-liter SOHC V-8 balances smooth and quiet
operation with excellent fuel efficiency and
enough power and torque to handle tough
assignments. With 230 horsepower at 4,250 rpm and
325 foot-pounds of torque at 3,000 rpm, Navigator
delivers enthusiastic throttle response and
spirited performance to demanding drivers.
Electronically
Controlled Powertain
The
same fifth-generation electronic engine control
computer (EEC-V) that regulates engine operating
variables also governs the automatic
transmission. The 4R100 transmission teamed with
the 5.4-liter V-8 has a lock-up torque converter,
four forward speeds, an overdrive top gear for
maximum highway fuel efficiency, and a handy
overdrive lock-out button on its shift lever.
Evev
Keel at All Times
The
Navigator standard load-leveling suspension
senses weight distribution and automatically
makes the necessary adjustments. The control
module collects height sensor output and air is
added to or subtracted from rear springs as
needed to maintain proper height in back.
An
estimated 75 percent of Navigator customers are
expected to select the Control Trac four-wheel
drive system. (Many SW owners in the south and
southwestern areas of the United States prefer a
4x2 driveline configuration, so the 4x4
alternative is offered as optional equipment.)
With 4x4, Navigator's load-leveling is a
four-comer system. In addition to the rear air
springs, front shock absorbers are fitted with
air bladders to permit leveling at each comer,
separately as needed.
A
"kneel-down" feature automatically
lowers ride height 1 inch for easier exit and
entry when the ignition key is fumed off. At
speeds below 25 mph with the four-wheel drive
system in low range, the load-leveling air
suspension automatically elevates ride height 1
inch above the normal ride height to improve
ground clearance for adverse driving conditions.
Front and rear gas-pressure shock absorbers and
anti-sway bars are tuned for a smooth ride and
supple control to handle the broadest range of
road surfaces and driving conditions.
Control
Trac
The
Navigator's 4x4 driveline is one of the most
advanced systems on the U.S. market and capable
of providing four-wheel-drive traction at the
twist of a dash-mounted control knob. Four modes
are available.
The
2H setting is used for normal on-road driving
with no unusual traction demands; torque is
delivered only to the rear axle.
In
the A4WD mode, Control Trac automatically selects
between two-wheel drive and four-wheel drive as
needed. The transfer case monitors driveshaft
speed and reports the onset of slippage at the
rear. When that occurs, a computer-controlled
electromagnetic clutch engages to add torque to
the front wheels. If the rear wheels regain grip,
the clutch automatically disengages. When
high-slippage conditions persist below 35 mph,
Control Trac keeps front drive engaged for five
minutes or until vehicle speed exceeds 45 mph.
This mode can be engaged at any time with the
vehicle in motion.
Control
Trac's 4H mode is preferred for snow, ice,
shallow mud or sand at normal driving speeds.
Drive to the front wheels is kept in permanent
engagement. Like A4WD, this mode can be engaged
on the fly.
A
4L setting is provided for the most adverse
conditions. To engage this low range, the vehicle
must be stopped, the shift lever must be placed
in neutral, and the brake pedal must be
depressed. Engine torque is multiplied by a
factor of 2.64, which is ideal for climbing or
descending steep grades or in deep snow, mud or
sand. To shift out of 4L, the procedure is the
same as the one used to engage this mode.
Many
SUV buyers are new to four-wheel drive systems,
so the Navigator driveline is simplified to do
the best job with minimal demands on the driver.
The A4WD setting is particularly helpful to those
who have a genuine need for maximum traction but
don't necessarily want to become an expert on the
fine points of transfer cases and differentials.
Wheels
and Tires
P245/75R-16
all-season tires mounted to cast-aluminum wheels
provide a balance between ride, quiet running and
all-around traction. Special effort went into
tuning these tires to help reduce tread noise
generated by textured pavement. Navigator models
equipped with Control Trac may be fitted with
17-inch cast aluminum wheels or 17-inch chrome
cast-aluminum wheels and larger all-terrain tires
with an outlined-white-letter sidewall design. In
addition to the traction benefits with these
P255/75-17 tires, their larger section and
diameter also provide a smooth, plush ride
quality.
Instantly
Recognizable as a Lincoln
A
chrome turbine-vaned grille topped with the
Lincoln star gives Navigator an unmistakable
Lincoln signature. This prominent grille is
mounted directly to a steel hood.
Flanking
the grille are clear-lens, complex-reflector
halogen headlamps, which lend a jewel-like
appearance in front. Large fog lamps below also
use a clear-lens complex-reflector design. The
front bumper fascia and fenders are smoothly
sculpted to coordinate not only with the
front-end design but also the bodyside moldings,
wheel-arch flares, and illuminated integrated
running boards in the side view. The 4x4 models
also have front tow hooks integrated into the
lower front bumper design.
The
Navigator liftgate is a one-piece design
supported by dual gas struts for easy opening. A
central toggle handle used to open either the
tailgate or the smaller liftglass is mounted
within the bright center applique panel. An
inside pull-down handle permits closing the
liftgate without stretching. Navigator's flip-up
rear glass panel is ideal for loading small
items. The full-size spare tire is stowed beneath
the rear of the vehicle so it doesn't take up
cargo space or necessitate unloading luggage in
the event of a flat.
Complex-reflector
designs for both the tail and back-up lamps are
repeated for a jewel-like appearance. The center
applique houses the license plate and back-up
lamps, while the rear glass surround is topped
with a light-emitting-diode type center brake
lamp. The rear bumper fascia integrates a Class
III trailer-tow hitch and a seven-wire harness.
Also included are a heavy-duty flasher, super
engine cooling and an auxiliary transmission
cooler. A roof-mounted luggage rack with
200-pound capacity is standard Navigator
equipment.
An
Upscale Interior
A
special Sound Isolation Package helps block the
intrusion of powertrain, wind and tire noise. The
Navigator interior has 18-ounce carpeting, a
soft-touch instrument panel fitted with genuine
burled walnut inserts and leather upholstery.
Navigator's
instrumentation cluster contains easy-to-read
analog gauges, including speedometer, tachometer,
odometer, trip odometer, coolant temperature
reading, oil pressure, charging and fuel level.
Instruments and controls are backlit.
The
center stack supports the audio system, the
Electronic Automatic Temperature Control panel, a
digital clock and Control Trac switch for 4x4
models. The glove box release is within easy
reach of the driver. Two slide-out cup holders
and a driver's-side storage bin and power point
are built into the dash.
The
front consoles are positioned both on the floor
and overhead to place other convenience features
within easy reach. The lower unit has open and
closed storage areas, two large cup holders, and
map pockets. The optional six-disc CD changer is
housed inside this unit. The rear edge of the
center console supports fan controls and vent
registers that direct cool or warm air to
rear-seat passengers, radio controls, two
headphone jacks, dual cup holders and a 12-volt
power receptacle. Overhead are map lamps,
switches for the power rear-quarter window, a
receptacle for sunglasses, and open storage. A
smaller electronic display reports average and
instantaneous fuel economy, distance to empty and
compass heading.
Bucket
seats are provided for both front- and middle-row
occupants, a first in the full-size SW segment.
Seating surfaces are upholstered in luxurious
leather trim as standard equipment. The front
seats are low-back designs with inboard armrests,
six-way power adjustment and two-way-adjustable
head restraints. Front lumbar adjusters are
manually operated. The rear console located
between the middle-row bucket seats provides dual
cup holders, a cavernous storage area and
removable tray. A 60/40 bench seat is available
for those interested in transporting up to three
middle-row passengers. This seat has
two-way-adjustable head restraints for outboard
passengers, a reclining seat back and a fold-down
center armrest with two cup holders. In addition,
all or part of the seat back can be folded to
increase storage.
A
memory system retains up to three settings for
the power driver's seat and the electrically
heated outside mirrors. In the event an interior
or under-hood lamp is left on, a battery-saver
feature automatically switches it off after 40
minutes.
Basic
safety equipment includes driver and passenger
air bag supplemental restraints and three-point
lap/shoulder belts for all outboard seating
positions. Shoulder belt height adjustment is
provided for front- and middle-row outbound
passengers. Rear-door child safety locks,
intrusion-resistant door beams, and
speed-sensitive interval wipers are also standard
equipment.
A
third-row bench seat providing space for three
more passengers is standard. Navigator can seat
up to eight people. By removing the third-row
bench and folding the second-row bench seat, the
cargo volume can be stretched to 116.4 cubic
feet. The 4x2's payload capacity is 1,800 pounds;
the 4x4's, 1,600 pounds. Tie-down hooks recessed
below carpet height and a removable net that can
be positioned up to beltline height help secure
cargo. Storage bins are built into the rear
sidewalls.
Navigator
offers a top-notch level of comfort and
convenience features. Among these:
Solar-tinted and privacy
glass blocks infrared rays from
Navigator's interior. That reduces heat
build up and fabric fading in sunny
climates.
The standard AM/FM stereo
audio system has a cassette player, four
speakers, and duplicate controls--both in
the steering wheel (volume, memory, band
selection) and at the rear of the console
for second-row passenger use with
supplied headphone jacks.
A premium 290-watt
audiophile sound system with cassette
deck and seven speakers is available
along with a six-disc disc CD changer
(mounted in the center floor console bin.
Power door locks and windows
are provided. There's a one-touch
driver's window for convenience at such
stops as a toll booth, bank or restaurant
drive-through window. After the ignition
is switched off, accessory power is
available for 10 minutes (or until a
front door is opened) to close the
windows and the optional moonroof. Remote
keyless entry is standard equipment.
The SecuriLock passive
anti-theft system uses a specially coded
ignition key to thwart vehicle theft. Any
attempt to start the vehicle without the
proper key automatically immobilizes the
engine.
Electronic speed control has
a tap-up/tap-down feature to provide more
comfortable cruising.
Options include an
electrochromic inside rearview mirror
that automatically cuts glare from rear
headlamps at night and a power moonroof.
The overhead glass panel can be opened
fully with one touch or tilted up for
extra ventilation. A universal garage
door opener built into the driver's sun
visor is included with the moonroof
option.
Auxiliary climate control
also is offered as optional equipment
without the moonroof. Heating and air
conditioning is delivered through the
headliner for increased comfort of
second- and third-row passengers. Five
registers--three ahead of and two behind
the second-row seats--add comfort.
Redundant controls are provided: one set
for the driver and another in a pod over
the second seat.
Genuine burled walnut wood
accents are fitted on the Navigator
instrument panel, floor console front
tray and door trim surfaces.
Navigator's wood and
leather-trimmed steering wheel also
includes duplicate audio and climate
control switches. |
