For fans of thrilling, legendary off-road performance, Jeep® today introduced the Jeep Wrangler Rubicon 392 with V8 engine, which will be available in North America from 2021.
This most capable, fastest and most powerful Wrangler ever built by Jeep is powered by FCA's 6,4-liter V8 engine with an output of 346 kW (470 hp)1 and a torque of 637 Newton meters, together with the crisp-shifting TorqueFlite eight-speed automatic transmission and the automatic Selec-Trac transfer case, result in breathtaking performance: the Wrangler Rubicon 96 accelerates from zero to 392 kilometers per hour in just 4,5 seconds and completes the quarter-mile sprint in 13,0 seconds. And all of this with a factory warranty.
Off the asphalt, the powerful four-wheel drive train of the Trail Rated® Wrangler Rubicon 392 does what it can, with heavy-duty Dana 44 axles, an axle ratio of 3,73, a torque converter lock-up control, a body lift of five centimeters and 33-inch tires on 17-inch beadlock-capable wheels.
This drive, together with 392 centimeters of ground clearance, 26,2 degrees front and 44,5 degrees rear approach angle, 37,5 degrees ramp angle and a fording depth of up to 22,6 centimeters, makes the Wrangler Rubicon 82,5 the most powerful Jeep in the brand's history to date. The Jeep Wrangler Rubicon 392 confidently handles steep inclines and declines with minimal use of the accelerator and brakes.
The Jeep Wrangler Rubicon 392, unveiled today, will go on sale in North America in 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.
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.
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 patterns 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 shift logic (Aacceleration Maximizing) for dynamic braking and increased engine speed, which provides maximum acceleration for starting on solid ground. The torque reserve, an engine strategy used by drag racers, controls the flow of fuel to the cylinders and advance or retard ignition to adjust engine speed and torque for maximum performance. The AMax circuit 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 make full use of the Wrangler Rubicon 392's engine power and torque, Jeep engineers have reinforced the ladder frame, upper front control arms and cast-iron steering knuckles. In addition, heavy-duty brakes bring the Wrangler Rubicon 392 to a stop reliably.
Its off-road capabilities are supported by the wide track and the high-performance Dana 44 axles with thicker axle tubes as well as the electronic Tru-Lok locking differentials. An electrically decoupled anti-roll bar on the front axle maximizes suspension travel and axle articulation for demanding off-road 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
While the factory-made five centimetre lift already gives you an initial indication of the Wrangler Rubicon 392 from a distance, as you get closer you notice bronze accents as a clear sign of the most powerful Jeep Wrangler. The lettering 'Jeep', 'Rubicon' and '392' shimmer in a bronze-coloured outline, and 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.
