Media Alert: Jeep
Jeep has announced details of it WRangler Rubicon 392 but it is not coming to Australia.
The most-capable, quickest, most-powerful Wrangler carries the 6.4-litre V-8, rated at 350kW and 637Nm of torque. Mated to the TorqueFlite eight-speed automatic transmission and Selec-Trac full-time active transfer case, the powertrain rockets the Jeep Wrangler Rubicon 392 from 0-100km/h in 4.5 seconds and the quarter-mile is ocmplete in 13.0 seconds.
The powertrain mates 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 tires on 17-inch beadlock-capable wheels.
The result is the most-capable Jeep Wrangler ever with 262mm 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 inches of water.
“This is the most-powerful, quickest, most-capable Jeep Wrangler we’ve ever built,” says Jim Morrison, Head of Jeep Brand – FCA North America. “The factory lift and abundant low-end torque from the V-8 makes the Rubicon 392 the king of the hills, whether you’re rock crawling at low speeds or powering up an incline. And when pavement replaces dirt, Rubicon 392 makes quick work of the road.”
The 2021 Jeep Wrangler Rubicon 392 goes on sale in the US in first quarter of 2021.
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 highway. A tank-mounted high-performance pump keeps the V8 fuelled under even the most demanding conditions.
A functional hood scoop feeds the Wrangler Rubicon 392’s engine with cool, denser, outside air, which leads to enhanced performance.
Should the Wrangler Rubicon 392’s functional hood scoop become restricted by snow/mud/debris, a secondary air path within the hood 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 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 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.
Off road, the Wrangler Rubicon 392 tricks include:
- Off-road Plus, with Sand and Rock modes: The push of a button maximizes the Jeep Wrangler Rubicon 392’s tractive capabilities. The modes adjust throttle, transmission shift points and traction control for peak performance on higher speed passes on sand terrain, as well as during low-speed rock crawling. The Off-road Plus drive mode also gives drivers the ability to lock the rear axle at high speeds while in “4H.”
- Selec-Speed Control manages vehicle speed in “4L” while traversing off-road terrain without requiring throttle or brake input. Selec-Speed Control is activated using a button on the dashboard and can be adjusted from 1-8km/h simply by using the Electronic Range Select
shift control.
The Wrangler Rubicon 392 on low-speed downhill descents uses the 6.4-litre V8’s engine braking, revised transmission torque converter lockup control and a 48:1 crawl ratio to manage vehicle speed without the driver needing to use the brake pedal.
