The 2021 Jeep Wrangler Rubicon 392 marks the return of a production V8 to the Wrangler engine bay after nearly 40 years.

For enthusiasts who crave soul-stirring, legendary off-road performance and a new level of on-road performance, Jeep introduces the V8 powered 2021 Jeep Wrangler Rubicon 392.

The most capable, quickest, most powerful Wrangler carries the 6.4-litre V8 engine, producing rated at 463bhp and 637Nm of torque. Mated to an eight-speed automatic transmission and Selec-Trac full-time active transfer case, the Jeep Wrangler Rubicon 392 accelerates from zero to 100km/h in 4.5 seconds.

Despite gaining a bigger and heavier engine, the Jeep Wrangler Rubicon 392 has lost none of its off-road capability
Away from the pavement, the Trail Rated Wrangler Rubicon 392's potent powertrain meshes with heavy-duty wide track Dana 44 axles, a 3.73 final drive ratio, transmission torque converter lockup control, a 2.0-inch lift and standard 33-inch tyres on 17-inch beadlock-capable wheels.

The result is the most capable Jeep Wrangler ever with 26cm of ground clearance, improved suspension articulation and manoeuvrability, approach, breakover and departure angles of 44.5, 22.6 and 37.5 degrees, respectively, and the ability to traverse up to 82.5cm of water.

An active dual-mode exhaust is standard and delivers a distinct sound. The system engages automatically, opening valves in the exhaust system, under higher engine loads to reduce exhaust back pressure. The driver can also activate the system with the press of a button.

With 463bhp and 637Nm of torque, 6.4-litre V8 engine provides ample power whether cruising on the open roads or traversing rugged trails
The fully electronic, eight-speed automatic transmission features on-the-fly shift-map changing. The transmission software relies on several input parameters to determine the appropriate driving conditions and adjusts shift pattern in response. The result is automatic shifting suited to the performance requirements of almost any driving demand.

The transmission's gear ratios afford the right response at the right time, from crawling over obstructions on the trail to smooth power delivery at expressway speeds, a product of smaller ratio steps between the gears. The Jeep Wrangler Rubicon 392's drivetrain puts the power down to all four wheels, all the time.

The heart of the driveline is a Selec-Trac full-time, active transfer case with a 2.72 low-range gear ratio. The transfer case has four driver-selectable modes, 4WD Auto, 4WD High, Neutral and 4WD Low. This full-time two-speed transfer case is intuitive and allows the driver to set it and forget it, while constantly sending power to the front and rear wheels.

The Wrangler 392 comes with comfortable leather seats, a new gauge cluster and Jeep's Off-road Pages to monitor the car while off-road
Bronze wheels measure 17 x 7.5 inches and are beadlock capable with an optional black locking ring available through Mopar.

The leather-appointed interior includes unique bronze stitching. The leather seats with Rubicon 392 nomenclature keep drivers comfortable with performance-inspired, integrated upper bolsters to hold occupants in place. To accommodate new engine specs, the gauge cluster receives all-new numbering and design.

The Uconnect system projects on a standard 8.4-inch screen. Loaded in the software is Jeep Off-road Pages which allows owners to monitor pitch, roll, altitude, GPS coordinates, drivetrain power distribution and more.
