2018 Jeep Wrangler Sahara Unlimited – Excellent Levels of Comfort and Superior Driving Dynamics. 2018 Jeep Wrangler Sahara Unlimited – Drive. Subscribe.
Engineered to master the most challenging off-road tracks, Jeep Wrangler is the result of more than seventy-five years of leadership in the development of 4×4 systems. Two four-wheel drive systems are available: Command-Trac – on the Sport and Sahara trim levels, and Rock-Trac – standard on the Rubicon trim configuration, the most rugged and capable model for off-road driving. Both systems feature the new Selec-Trac full-time two-speed transfer case for a continuous monitoring and management of the torque sent to front and rear wheels.
In details, Command-Trac four-wheel drive system features a two-speed transfer case with a 2.72:1 low-range gear ratio, heavy-duty next-generation Dana front and rear axles with 3.45 rear axle ratio for the petrol version, and 3.73 for the diesel versions.
Jeep Wrangler Rubicon models provide additional off-road prowess and are equipped with the Rock-Trac 4×4 system, featuring a two-speed transfer case with 4.0:1 low-range gear ratio and front and rear heavy-duty next-generation Dana 44 axles and Tru-Lok electric front- and rear-axle lockers to tackle the most extreme off-road trails. The standard equipment also includes a front and rear axle ratio of 4.10 for the petrol models and 3.73 for the diesel versions, Tru-Lok electric front- and rear-axle lockers to tackle the most extreme off-road trails.
Rubicon models also offer added articulation and total suspension travel with help from an electronic sway-bar disconnect. This system allows drivers to disconnect the front sway bar to deliver additional wheel travel for traversing the toughest trails. Wrangler Rubicon petrol models have a maximum and improved crawl ratio of 77.2:1 and of 70.3 on the Rubicon diesel versions – both of which makes scaling any obstacle on the trail easy.
On the all-new Jeep Wrangler, the Trail Rated badge includes the following features:
Command-Trac 4×4 system with 2.72:1 crawl ratio standard on the Sport and Sahara models;
Rock-Trac 4×4 system with “4LO” ratio of 4:1 and Tru-Lok locking differentials standard on Rubicon models;
Skid plates and rear tow hooks;
Benchmark approach angle (2-door Rubicon) of 36.4 degrees, breakover angle of 25.8 degrees, departure angle of 30.8 degrees and ground clearance of more than 25 cm;
Up to 76 cm of water fording;
Up to 1,500 kg of towing capacity (2-door models) and 2,500 kg (4-door models)
The Jeep design team gave the legendary seven-slot grille a more modern look that now shows both of the outer grille slats intersecting with the headlights, paying homage to the legendary CJ model. The top of the keystone-shaped grille has been gently swept back for improved aerodynamics.
In the Sahara and Rubicon versions, the available headlights and LED fog lights feature crisp white lighting and add to the Wrangler’s distinctive look. The daytime running lights are positioned on the front of the trapezoidal wheel flares. From behind, traditional square tail lamps feature available LED lighting.
The windshield is tilted to an optimal degree to improve aerodynamics, and features a new four bolt design at the top of the windshield’s frame to allow the windshield to fold down quickly and easily. The new header bar now connects the A-pillars and remains in place even when the windshield is folded down. This allows the rear-view mirror can remain in place even when the windshield has been folded away. Two-piece body-color fender flares with a black lower insert are standard on Sahara.
New lightweight, high-strength aluminum doors feature the size of the Torx bit tool size stamped directly onto the hinge to easily remove the doors.
All Wrangler models now feature body-colored sport bars, which are welded to the body and feature integrated grab handles.
Jeep Wrangler is a unique vehicle thanks to the several combinations offered to owners to enjoy open-air adventure, and features different windshield and top solutions that allow customers to choose multiple configuration possibilities.
As the only authentic full open-air 4×4 SUV available on the market, the all-new Jeep Wrangler offers various top combinations to ensure even more open-air freedom.
The all-new, easy-to-use Sky One-Touch powertop strengthens Wrangler’s promise of utility and adventure by allowing occupants to retract the full-length open canvas roof with a push of a button.
It will join two additional roof configurations available on the all-new Wrangler: a new Zipperless Premium Sunrider soft top and a lighter and easy-to-use Freedom Top, a removable, three-panel hard top.
Specifically, the Zipperless Premium Sunrider soft top has been improved by adding two additional bows to manage the fabric. This new design helps to quieten wind noise and allows for easier access to partial and full open top positions.
