JEEP
LIBERTY
| By
the time you read this new,Jeep---the Liiberaty---should have
been at the dealership for around 2 1/2 months. You've probably
seen one driving down the road, and if you are a true Jeep freak
you already own one. If you've got one outside we can hopefully
help you learn a thing or two about your new ride. If you don't
have one, pay attention and take notes since you will be tested
on this stuff later. |
| Generally
speaking, hard-core Jeep fans are scared of phrases like "superior
on-road refinement," or "independent front suspension."
Have no fear --- somewhere under that cute facade beats the
heart of a true Jep. How do we know, you ask? Well a few months
ago, the DaimlerChrysler corporation allowed us to drive the
new KJ both on-and off-road. The result was that we were pleased
with how the Liberty dealt with the obstacles of modern road
driving and some fairly tough off-road trails that would make
many of the new car-based SUVs pee in their car-based pants. |
| WHY
THE LIBERATY HAS BIG SHOES TO FILL |
- The
Cherikee won 4-Wheel & Off-road's 4x4 of the Year
both times it was entered.
|
- The
first time the XJ won it had a GM 2.8L V-6. If that
didn't keep it from winning we can't imagine what
could.
|
- The
Grand Cherokee won 4 Wheel & Off-road's 4x4 of
the Year five times.
|
- the
Cherokee was frist introduced in'84 --- that's 17
years without a major body or frame redesign.
|
|

| THE
COMPETITION |
| Jeep
provided us with a few examples of what they consider
the KJ's competion, and we have chosen this as an opportunity
to make fun of them. |
| We
have said it time and time again : Do not attempt to convert
your car into a truck. Now, not only do we have to deal
with some joker from Alabama with a Renualt Le Car that
runs 35-inch mud tires and wants into Jp because it's
got a Dana 30 from a Leep, we also have to deal with huge
car companies trying to make cars more off-road worthy. |
|
| ON
- ROAD DRIVING IMPRESSIONS |
| We
had the opportunity to drive the KJ with both the 3.7L
V-6 and the 2.4L i4. the V-6 model was an auto although
we pined for the manual, which would definitely be a bit
more spirited. The V-6 provides plenty of power, but lacks
the flat torque band of the older 4.0L I-6. The automatic
did a good job of shifting, and even seemed to |
downshift
while on the highway when a steep decent was encountered
with the cruise control engaged. The four-cylinder provided
good lowend power but was left struggling up longer higher-speed
inclines to the point of somewhat aggravated downshifts
and hands patting the dash while chanting "come on,
come on, come |
on."
both KJs had smooth but sportive on-road handling
despite being somewhat heavier than a Cherokee. this extra
weigh of the KJ seems to nullify the added 20 or so horsepower
that the KJ's new V-6 has over the XJ's straight-six. |
| OFF-ROAD
DRIVING IMPRESSIONS |
| With
4 inches of compression and 4 inches of drop this
may be one of the better IFS setups for off-road,
but like most IFS trucks the KJ gets most of its
flex from the rear suspension. The visibility is
great but the lack of a definitive |
front corner makes sharp turns between trees difficult
without compromising the front fender flares. We
used the skid paltes a lot off-road, but with good
approach and departure angles, and |
with
the optional limited slip we were able to get through
some very tough sections of the trail without too
much troble. For a stock truck the Liberty works
darn well on the trails. |
|
|

| LIKES |
- Some
cool new ideas have been employed on the KJ.
- Comfortable
ride on-road and off-road.
- The
four-cylinder has good low-end power for four-cylinder.
- Good
approach and departure angles.
|
|
| DISLIKES |
- The
hood is rounded at the corners for visibility
like a TJ, which is good. The problem is now
you can't see where the fender ends. this increases
the chance that you will unintentionally introduce
your fender to a rock or tree along twisty trails.
- All
four-wheels-drive KJs should come with tow hooks
and skidplates.
- Where
is the Up-Country suspension?
|
|
|
| SOME
COOL NEW STUFF |
- The
2.4L four is borrowed from other Chrysler cars such
as the PT Cruiser and brings with it the NV1500 Manual
five speed, which features a dual-mass flywheel said
to absorb harsh shifting, sort of like a torque converter
does in an automatic.
|
- When
you shift into 4-Lo the KJ's computer system modifies
the idle speed and adjusts the antilock braking system
for better off-road performance.
|
- Despite
the IFS, the Dana 30 centersection should accept just
about any aftermarket traction-adding device for the
good ol'Dana 30 straight-axle.
|
- The
3.7L V-6 offers aluminum heads, a composite molded-plastic
intake manifold, counter rotating balancing system,
dual-knock sensors, and a Zero-:eak engine sealing
system.
|
- the
exhaust has resealing coupler that will separate if
the muffler gets hung up on a rock. this break in
the exhaust makes the KJ grumble like a street rod
until the rock is passed and the coupler reseals the
exhaust system.
|
|
 |
| HONDA
CRV |
| A
civic-based cute-ute for the masses. We're sure that it
gets great gas mileage, but our precious masculinity would
be far too damaged be seen in one regularly. |
| GRIPES |
- the
halfshafts make good toothpicks.
- "Real
Time 4WD," A two=legged hamster with one eye
and irritable bowel syndrome has more off-road prowess.
|
|
 |
| RAV4 |
| Toyota
is a phenomenal car and truck manufacturer, but you can't
make a Camry an SUV by adding a few half shafts and some
plastic fender flares. |
| GRIPES |
- Someone
put the motor in sideways.
- That
is not a tow hook.
|
|
 |
| FORD
ESCAPE |
| We
are not sure which car Ford based the Escape on, but who
cares? It is more of a car than it could ever be a truck.
At least it has aV-6 available which means you may be
able to use momentum to get further off-road before the
thing gets hopelessly stuck. |
| GRIPES |
- Could
be a fun car but it's too high off the ground to corner
wall and ti's too low to be of any practiceal use
off-road unless you think wet grass is an extreme
off-road adventure.
|
|
 |
| NISSAN
XTERRA |
| OK,
finally we have a contender. This actually can be considered
an SUV. It has a transfer case which seems to be as elusive
on so-called SUV as a sane cabdriver in New York City.
Thankfully, this SUV is based on a truck, Nissan's Frintier.
Unfortunately, the Frontier is nit very capable off-road. |
| GRIPES |
- The
low-range ratio is too high and does not afford the
slow speed and vehicle control that most transfer
case-equipped rigs do.
- It's
got a V-6, but where's the beef?
