Treading a fine line between tradition and technology and ever-ready to
dispatch inhospitable terrain in its stride, the
Jeep Wrangler Rubicon is the
best off-roader from the American manufacturer whose name has long been a
byword for rugged off-roaders. Launched in 2018 with more tech and refinement,
the latest Wrangler Rubicon is as capable as factory-spec passenger off-roaders
get.

Boasting an
extensive complement of off-road hardware and three fully detachable roof
choices, it also delivers a true al fresco off-road experience that includes
detachable doors and a fold-down windscreen.
Tracing its
origin back to the iconic 1941 Willys Jeep, the current “JL” series Jeep
Wrangler is the most advanced yet. However, it remains true to tradition as a
highly capable authentic off-roader with rugged body-on-chassis construction
and integrated rollover bars. Incorporating some lightweight material and a
slightly more raked-back design as a small concession to aerodynamic efficiency,
the Wrangler’s hallmark design cues are accounted for and include its
seven-slot grille, tapered bonnet, protruding wheel-arches, short overhangs,
and a boxy, upright body.
Offered in two-
or four-door guise, the Wrangler Rubicon is aesthetically better resolved in
the former. Its shorter wheelbase is better proportioned and sits with a more
classically rearwards orientation. Driven on Austrian alpine routes, the
smaller two-door also proved maneuverable on narrow off-road trails, with good
sightlines and a tighter 10.36m turning circle. Crucially, its shorter
wheelbase also provides a more generous 25.85° break-over angle for traversing
deep ruts and sharp peaks.
Rugged and
responsive
The most off-road capable
Wrangler, the Rubicon is powered by the same
familiar 3.6-liter V6 ‘Pentastar’ engine and slick-shifting eight-speed
automatic gearbox as other variants. Developing 285HP at 6,400rpm and 347Nm
torque at 4,100rpm, the Rubicon’s naturally-aspirated engine is responsively
eager and progressively linear from tick-over to the rev limit. Allowing
precise throttle control to modulate power over tricky terrain, the Rubicon is
nevertheless versatile and muscularly confident in mid-range. It can also be
driven in rear-wheel-drive for on-road efficiency or “auto” four-wheel-drive
for most circumstances.

The Wrangler’s
four-wheel drive features full-time high and low ratio four-wheel drive modes
for more demanding off-road driving. In conjunction with an aggressive
Rubicon-spec 4.1:1 final drive ratio, the latter provides a very low and steady
77.2:1 crawl ratio for extreme traction or incline requirements. The more
aggressive final drive also delivers more responsive acceleration but
conversely limits top speed to 156km/h and slightly increases fuel consumption.
The Rubicon meanwhile rides on chunkier LT285/70R17C off-road tires with big,
wide-spaced treads for mud and snow.
Thoroughly
capable off-road with heavy gauge tubular steel rock rail underbody protection
and increased 255mm ground clearance, 762mm water fording capability, and great
36.4° approach and 30.8° departure angles, it is, however the Rubicon’s locking
differentials and electronically-controlled disconnecting anti-roll bars that
make it so special. With individually lockable front, center, and rear
differentials keeping wheels turning in unison, the Rubicon can keep driving
over difficult terrain, even if only one wheel maintains traction or ground
contact.
Capable and
comfortable
Gaining longer wheel travel, significantly improved axle articulation,
and better ground contact over sharply uneven surfaces, the Rubicon also rides
in a more forgivingly supple and fluent manner over rough dirt roads when
anti-roll bars are disconnected. That said, anti-roll bars are best kept
connected on faster, less demanding, and more winding routes — and on tarmac —
to ensure better cornering body control and steering precision. Requiring more
turns than many modern systems, the Rubicon’s slow ratio steering is forgiving
over rough surfaces, but remains accurate on the road.
Rare even among
most off-road capable SUVs in riding on live axle suspension at both rear and
front, the Wrangler tempers this rugged design with comfortable, longer
traveling coil springs. With each side reacting to movement on the opposite
side, the Wrangler can be a busier ride than some less hardcore SUVs, but is
nevertheless surprisingly refined, with anti-rebound dampers proving effective
in keeping it vertically settled over crests and dips. Chunky tires might
meanwhile make the Rubicon noisier than other Wranglers, but they nevertheless,
comfortably absorb imperfections.

Nimble with tidy
turn-in, short wheelbase, and high driving position, the Rubicon is easily
placed on- or off-road. Stable on the highway and well insulated inside, the
Wrangler’s driving position is supportive and ergonomic. Featuring sportier
designs and improved quality and textures inside, the Wrangler is well-equipped
and includes an enhanced infotainment system with off-road gauges. It also
features dedicated storage space for its detachable roof bolts and tools.
Available driver assistance systems meanwhile include rear cross path
detection, parking camera, and Electronic Roll Mitigation.
