For enthusiasts who crave soul-stirring, legendary off-road performance and a new level of on-road performance, Jeep® has introduced the V8-powered 2021 Jeep Wrangler Rubicon 392 for customers in the North American market.
The most-capable, quickest, most-powerful Wrangler carries the 6.4-litre V8, with 470hp and 637Nm of torque. Mated to the crisp-shifting TorqueFlite eight-speed automatic transmission and Selec-Trac full-time active transfer case, the powerplant rockets the Jeep Wrangler Rubicon 392 from zero to 60 mph 4.5 seconds and the quarter-mile in 13.0 seconds.
Away from the pavement, the potent powertrain of the Trail Rated® Wrangler Rubicon 392 meshes with heavy-duty wide track Dana 44 axles, a 3.73 final drive ratio, transmission torque converter lockup control, a 2-inch lift and standard 33-inch tyres on 17-inch beadlock-capable wheels.
The result is the most-capable Jeep Wrangler ever with 10.3 inches of ground clearance, improved suspension articulation and manoeuvrability, approach/breakover/departure angles of 44.5/22.6/37.5 degrees and the ability to traverse up to 825mm of water.
Jeep engineers put it to the test: The 2021 Jeep Wrangler Rubicon 392 confidently climbs up and down steep grades with minimal throttle and brake input.
The addition of the 6.4-litre engine marks the first time in nearly 40 years a V8 has been a factory option for the Wrangler. Tuned specifically for the Jeep Wrangler Rubicon 392 and its functional bonnet scoop, the engine produces 470hp and 637 Nm of torque.
Critical to performance on-road and off, nearly 75 percent of the peak torque from the Wrangler Rubicon 392 is available just above engine idle speed. This delivers exciting performance, whether enabling a 4.5-second zero to 60mph time or crawling up steep grades.
The performance of the 6.4-litre V8 is based on a cast iron cylinder block and aluminium heads, accented with an active intake manifold, variable camshaft timing, twin spark plugs per cylinder, sodium-filled exhaust valves, hollow-stem intake valves and piston oil cooling jets. The Wrangler Rubicon 392 engine is fitted with a rear-sump oil pan, high-mount alternator and free-flowing exhaust manifolds.
Fuel Saver Technology with cylinder deactivation seamlessly shifts to smooth, high-fuel-economy four-cylinder mode when engine loads are light, such as cruising on the motorway. A tank-mounted, high-performance pump keeps the V8 fueled under even the most demanding conditions.
A functional bonnet scoop feeds the engine in the Wrangler Rubicon 392 with cool, denser, outside air, which leads to enhanced performance.
Jeep engineers ensured the V8 engine gets fresh air, regardless of the terrain and weather. The Wrangler Rubicon 392 features a Hydro-Guide™ air intake system with a tri-level ducting system and 56 litres per minute – away from the engine’s incoming air. This enables the Wrangler Rubicon 392 to traverse water up to 825mm deep worry free, even if a bow wave washes over the bonnet.
Should the functional bonnet scoop become restricted by snow, mud or debris,a secondary air path within the bonnet structure feeds the engine, making it possible for the Wrangler Rubicon 392 to reach top speed even with a fully blocked primary air path.
An active dual-mode exhaust is standard to deliver an exhilarating and unmistakable 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. The dual-pipe performance exhaust system is finished off with unique quad exhaust tailpipes.
The drivetrain in the Jeep Wrangler Rubicon 392 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 2.72:1 low-range gear ratio. The transfer case has four driver-selectable modes: 4WD Auto, 4WD High, Neutral, 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 Selec-Trac transfer case also allows for Wrangler Rubicon 392 to be flat-towed.
The 2021 Jeep Rubicon 392 keeps to the original design theme of Wrangler with bold and functional cues, a wide stance and its recognisable trapezoidal wheel flares. The factory 2-inch lift adds to the vehicle’s character and presence.
The Wrangler Rubicon 392 carries bronze accents to mark the most powerful Jeep Wrangler ever. bronze traces “Rubicon” on the bonnet, covers the front and rear tow hooks, and FOX Shocks’ decal outline. It also outlines the Jeep badge and the Trail Rated badge.
Adopted from the Jeep Gladiator Mojave, a 40mm raised bonnet with fully functional bonnet scoop, provides cold air intake and greater water fording capability. It also carries a “392” badge on each side, signifying the most cubic inches ever offered in a Jeep Wrangler.
The grille design delivers greater airflow and cooling of the 392 V8.
Bronze wheels measure 17x7.5 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. Available on the Jeep Wrangler for the first time, the leather-wrapped, performance steering wheel features wheel-mounted paddle shifters for fast access to the eight-speed transmission and management of 637Nm of torque.
The Uconnect system projects on a standard 8.4-inch screen. Loaded in the software, the Jeep
Off-road Pages allow owners to monitor pitch, roll, altitude, GPS coordinates, drivetrain power distribution and more.
The 2021 Jeep Wrangler Rubicon 392 is available in nine exterior colours: Black, Bright White, Firecracker Red, Granite Crystal Metallic, Punk ’n Metallic, Sarge Green Metallic, Snazzberry Metallic, Sting-Gray Metallic and Billet Silver Metallic, all with a black interior.
