And all of this with a factory guarantee.

Away from the asphalt, the powerful four-wheel drive train of the Trail Rated® Wrangler Rubicon 392 shows what it can do, with heavy-duty Dana 44 axles, an axle ratio of 3,73, a torque converter lock-up control, the body lift by five centimeters and the 33 Inch tires on 17 inch beadlockable wheels. This drive makes the Wrangler Rubicon 392 together with 26,2 centimeters of ground clearance, 44,5 degrees front and 37,5 degrees rear Approach angle, 22,6 degree ramp angle and a wading depth of up to 82,5 centimeters to the most powerful Jeep in the history of the brand to date. The Jeep Wrangler Rubicon 392 confidently masters steep inclines and declines with minimal use of gas and brakes. The Jeep Wrangler Rubicon 392 unveiled today will go on sale in North America from the first quarter of 2021.

Top performance and lots of torque

With the introduction of the 6.4 V8, an eight-cylinder engine can be ordered as a factory option for the Wrangler for the first time. The V8 was adapted for the installation space under the bonnet of the Wrangler Rubicon 392, where it develops 346 kW (470 hp) and delivers 637 Newton meters of torque. Almost 75 percent of the torque is already available just above idling speed. This results in exciting performance values, regardless of whether the Wrangler Rubicon 392 accelerates from a standstill to 4,5 kilometers per hour in 96 seconds or crawls up steep inclines.

active intake manifold, variable camshaft control

The 6.4 V8 is built on a cast iron block with aluminum cylinder heads. An active intake manifold, variable camshaft control, two spark plugs per cylinder, sodium-filled exhaust valves, intake valves with a hollow shaft and oil spray cooling for the piston crowns ensure performance as well as thermal resistance. If only a small part of the power is required when swimming in everyday traffic, a shut-off device for four of the eight cylinders ensures lower fuel consumption.

Air scoop on the hood

The 6.4 V8 gets the cool, dense air it needs to breathe, among other things, from an air scoop on the bonnet. The challenge for the Jeep engineers was to ensure this air supply in all circumstances that the Wrangler Rubicon 392 could be exposed to - regardless of terrain and weather. To do this, they developed the Hydro-Guide ™ air intake system, which in the Wrangler Rubicon 392 consists of a three-stage duct system with a number of drains, including a drainage outlet in the air box that can divert any incoming water away from the intake air. Due to the high capacity of this drain with up to 56 liters per minute, the Wrangler Rubicon 392 can wade through water up to 82,5 centimeters deep, even if the bow wave should slosh over the bonnet and thus also into the air intake hood. Also, when the hood air scoop is compromised by snow, mud, or other debris, a secondary air path within the hood structure supplies the V8 with air. The Wrangler Rubicon 392 can reach its top speed even with a completely blocked primary airway.

A Jeep Wrangler with a V8 has an inspiring and unmistakable sound. This is ensured by the active dual-mode exhaust system with valves that open automatically when the engine is loaded to reduce the exhaust gas back pressure. The driver can also activate the system at the push of a button. The double-flow exhaust system ends with a four-way exhaust pipe.

Well equipped for performance

The proven TorqueFlite 8HP75 eight-speed torque converter automatic transmission with high torque capacity enables quick, precise gear changes under all driving conditions. For the first time, a Wrangler driver can also manually select gear changes using aluminum paddles on the steering wheel.

The fully electronic transmission control selects different shift schemes depending on the respective input parameters for different driving conditions and thus ideally adjusts the transmission to the performance requirements of almost every situation. The drive calibration of the Wrangler Rubicon 392 includes a torque reserve and a so-called AMax switching logic (Acceleration Maximizing) for dynamic starting with the brake and increased speed, which provides maximum acceleration for starting on solid ground. The torque reserve, an engine strategy used by drag racers, controls the fuel flow to the cylinders as well as advanced or retarded ignition in order to adjust the engine speed and torque to maximum driving performance. The AMax gearshift is already used in the launch control of the Jeep Grand Cherokee Trackhawk.

Power for the asphalt, ready for the Rubicon

The drive of the Jeep Wrangler Rubicon 392 brings its power to all four wheels, constantly. The heart of the fully automatic four-wheel drive is the active Selec-Trac transfer case with an off-road reduction ratio of 2,72: 1. The transfer case has four driver-selectable modes: 4WD Auto, 4WD H, Neutral and 4WD L. The Selec-Trac transfer case also allows the Wrangler Rubicon 392 to be towed.

Off-road, the Wrangler Rubicon 392 has the legendary capabilities Jeep is known for.

This includes:

  • Offroad Plus, with the modes sand and rock: One push of a button maximizes the traction capabilities of the Jeep Wrangler Rubicon 392. The modes set the accelerator pedal, gear shift points and traction control so that the best performance is achieved both on faster passages on sand and when crawling over rock . The “Offroad Plus” driving mode also gives the driver the option of locking the rear axle differential in 4WD High at high speeds.
  • The cruise control Selec-Speed ​​Control controls the vehicle speed in "4WD Low" without having to press the accelerator or brake. Selec-Speed ​​Control is activated via a button, the automatically maintained crawling speed can be set from one to eight kilometers per hour and easily changed while driving.

Reinforced frame for the most powerful Wrangler

To take full advantage of the Wrangler Rubicon 392's engine power and torque, Jeep engineers reinforced the ladder frame, upper front wishbones, and cast iron steering knuckles. In addition, heavy-duty brakes reliably bring the Wrangler Rubicon 392 to a standstill. Its off-road capability is supported by the wide track and the high-performance Dana 44 axles with thicker axle tubes as well as the electronic Tru-Lok limited-slip differentials. An electrically decoupling anti-roll bar on the front axle maximizes suspension travel and axle articulation for demanding terrain conditions.

In addition to the tried and tested five-link front and rear suspension, a lift height of five centimeters and single-tube high-pressure gas shock absorbers from FOX maximize the handling and comfort of the Wrangler Rubicon 392.

Bronze as a sign of something special

If the factory elevation of five centimeters gives an initial indication of the Wrangler Rubicon 392 from a distance, bronze accents are noticeable as a clear characteristic of the most powerful Jeep Wrangler when you get closer. The lettering 'Jeep', 'Rubicon' and '392' shimmer in a bronze-colored outline, the 'Trail Rated' emblem and the tow hooks are also in bronze.

Adopted from the Jeep Gladiator Mojave, an engine hood that is 40 millimeters higher arches over the V8, with an air intake scoop for fresh air supply to the engine and for wading ability. The bronze-framed '392' lettering on the sides of the air scoop indicate the largest displacement that Jeep has ever offered for a Wrangler: 392 cubic inches or 6,4 liters.

The 17 x 7,5 inch, beadlock-capable wheels are also kept in bronze. The original black locking ring is available from Mopar.

The interior remains with the bronze tone for the accent stitching of the leather upholstery and the 'Rubicon 392' emblem in the front seat backrests in the theme of the exterior design. New - and exclusive - for the Rubicon 392 are the shift paddles for the first time to be found on a Wrangler steering wheel for quick manual intervention in the gear changes of the eight-speed automatic transmission.

The modern Uconnect infotainment system with a full-color TFT touchscreen with a screen diagonal of 21 centimeters is of course also standard in the Top-Wrangler. Rubicon drivers in particular appreciate the off-road pages contained in the software, which display parameters such as body inclination, height above sea level, GPS coordinates, drive force distribution and a lot more in attractive and intuitive graphics.
