2012 Jeep Wrangler delivers unmatched off-road capability with
legendary four-wheel drive and is produced with more than seven decades
of 4x4 engineering experience. Wrangler continues to offer a

offers a six-speed manual transmission ? in addition to its new
five-speed automatic transmission.
new automatic transmission benefits the 2012 Wrangler as much as the
new engine with more refined shifting and gear selection. By increasing
the number of speeds from four to five, the transmission allows the
engine to operate in a more efficient RPM range, which helps increase
fuel economy. More speeds also enable the engine to remain in the torque
curve, increasing acceleration. The 2012 Jeep Wrangler boasts a
25-percent improvement in 0?60 mph time, which is now 8.4 seconds. Also,
a lower first-gear ratio in the new automatic transmission gives the
Wrangler more off-road capability via a lower overall crawl ratio.
Wrangler is now available with more axle gear ratios allowing customers
to optimize fuel economy and/or vehicle capability. Wrangler is
available with 3.21, 3.73 or 4.10 ratios depending on model. Also,
Wrangler offers towing capability up to 3,500 lbs.

2012 Jeep Wrangler underwent millions of durability testing miles
during development in the company's scientific labs, at its proving
grounds and on public roads in various climates.
Wrangler's 3.6-liter V-6 Pentastar engine recorded more than 12 million
customer-equivalent miles on engine dynamometers prior to production.
Testing was increased by 50 percent compared to previous Chrysler Group
V-6 engines, to guarantee a long life against severe conditions and
accommodate high-load applications such as trailer towing. Reducing
noise, vibration and harshness was a key objective for every engine
component and was achieved using advanced computer-aided engineering
the Wrangler approached production, the company also tested day and
night, on- and off-road to put the equivalent of three years of wear and
tear on the vehicle in approximately three months time. This
accelerated testing occurred on public roads, paved and unpaved, in an
attempt to find and fix any issues before the first SUVs were delivered
to customers. The test drivers checked all the functional aspects of the
vehicle, such as heating and cooling, window operation, convertible and
removable hardtop operation and navigation system.
The 2012 Jeep Wrangler and Jeep Wrangler Unlimited are built in the Toledo Supplier Park in Toledo, Ohio.
The plant features the flexibility to integrate the all-new powertrain
with the addition of new engine carriers and transmission lift
The 3.6-liter V-6 engine is manufactured at the Trenton engine plant in Michigan. The five-speed automatic transmission is produced in Kokomo, Indiana (ITP2), and the manual six-speed transmission is produced in Gaggenau, Germany.
Sahara and Rubicon models offer a body-color hardtop and fender flares.
A new paint process was developed to match the body color to the sheet
molded compound (SMC) hardtops that exceeds the corporate quality
standards of paint adhesion and UV resistance in the harshest
environments. The body and top are painted separately with blended and
matched paint to assure color continuity.

2012 Jeep Wrangler: First Drive
for the Porsche 911, no vehicle has preserved its purity of essence
like the Jeep Wrangler, an original creation as American as jazz and Kim
Kardashian's ass. Now its new Italian don has blessed it with the
latest corporate power parts. Could change actually make the Jeep
Disclaimer: Jeep wanted me to drive the Wrangler so bad they flew me to Oregon and housed me...[in a hotel.]
Last year, the funslayers at Consumer Reports proclaimed the Jeep
Wrangler the worst vehicle for sale in America, even over the Smart
ForTwo. Noisy! Harsh! Vibrate-y! ? which, to Jeep enthusiasts, are
features, not bugs. But the funslayers have a point.
Since it came home from World War II and began civilian life as a
glorified farm implement, the Wrangler has lured thousands of buyers
promising a jamboree of toughness, only to reward them with the on-road
manners of a surly mule and the durability of a box of pinot grigio at a
Josh Grobin concert.
Fiat saved Chrysler from its death wobble, the Jeep has undergone an
inside-out transformation meant to address its faults among the
Philistines, leading to this: a Wrangler with more standard horsepower
than a Nissan 350Z sported just five years ago.
True Wrangler acolytes embrace changes with the giddy enthusiasm of
Popes. Fans have never stopped mourning the death of the antique AMC
4-liter inline six motor, and with reason; The advent of the 3.8-liter
V6 in 2007 with the heavier JK chassis and its cranky four-speed
automatic transmission dragooned from Mopar minivans left Wranglers
feeling as if forward motion came from a hundred junebugs bridled to the
front tow hooks.
The new 3.6-liter Pentastar V6, now the go-to power for all things
Chrysler, sports 285 hp and 260 lb-ft of torque, weighs 90 pounds less
that the boat-anchor 3.8. Changes for Wrangler duty include new intakes,
exhaust and an alternator that will give mechanics a "hey, lookit"
moment: To ensure the engine could survive the Wrangler plowing into 30
inches of water, the alternator was not only raised but reversed, with
its pulley facing the block. Behind it is Chrysler's five-speed
automatic transmission, the one 80% of buyers will take, along with the
carryover six-speed manual for those who want to keep the mule whip in
pavement, the Wrangler now gallops to 60 mph in 8.4 seconds ? a full
three seconds faster than the previous edition. Combined with last
year's extreme interior improvements and some additional soundproofing,
no longer does driving a Wrangler on a freeway resemble marshaling
mountain goats through a windstorm. There's still more noise than a
family sedan, and the Bridgestones' chatter comes through the floor, but
it's at a dinner-table level, not "Bad Girls Club." The five-speed
plays well with the V6, blipping the throttle before downshifts and
letting it brush redline under a full boot.
The steering still remains more truck than car, but the suspension
doesn't attempt to exhaust passengers with urgent updates about road
seams; it also tracks towards just slight understeer. The weakest link
is the brakes; soft as a deep-fried butter stick, you find the pedal
down a few inches before the orders arrive to the wheels.
But Jeep purists want to know about going slow, which is how I ended
up in a Wrangler Rubicon on a clear-cut hillside in Oregon's Tillamook
forest with my nose closer to zenith than the horizon and wheels
spinning on rocks the size of garden gnomes. Those of us who like cars
attached to the ground aren't used to windshields of nothing but blue
sky, and a few days of journosaur trampling had left the trail with a
slick coat of dust.
It's situations like this where the utter genius of Jeep engineering
kicks in. At 2,000 rpm, the new 3.6 is pumping 96% of its total torque.
Thanks to the extra lubed ring in the five-speed gearbox, a 2012 Jeep
with the standard 3.73 rear axle sports a better crawl ratio ? the
measure of how that torque is multiplied through the axles to the rocks ?
than last year's Rubicon with the heavy-duty 4.10 axle. With the front
sway bars electronically disconnected, the catawampus tires simply took
an extra swig from the accelerator and moved on. Yes, the track was
arranged by Jeep for Jeep ? but few vehicles can survive crawling
through holes large enough to swallow a Smart.
The good news on prices is that Chrysler held the base sticker at par
with the old model, around $22,000. The bad news is that fully loaded
varieties quickly ascend to heights of $34,000, and since Chrysler is
setting sales records for Jeep Wranglers and struggling to keep up with
demand, there's no plans to either adapt the four-cylinder diesel those
sooty Europeans get or build a pickup truck at the factory.
By taming its on-road manners while preserving its off-road skills,
Chrysler has finally made the Wrangler a truck that people can live
with, not in spite of. After seven decades of hauling everything from
farm implements to Daisy Duke, the 2012 Jeep Wrangler is the most
