Why buy the Rubicon 392?


The 470-horsepower Jeep Wrangler Rubicon 392 is a shaggy commando of tire-frying, trail-crawling confidence. It roams the wilds and street as the lone wolf or the bull buffalo keeping watch over the herd. Its rumbling 6.4-liter V-8 engine is the call of the wild.

Jeepers have been shoehorning V-8s into Wranglers for years. But this Hemi honcho will get drivers out of trouble faster than they can get into it. The 392-cubic-inch pushrod V-8 can accelerate to 60 mph in 4.5 seconds, Jeep says, and pass the quarter-mile in 13 seconds. That’s a thundering accomplishment for it 5,103-pound curb weight.

With the eight-speed automatic transmission, the 6.4-liter has fuel-economy ratings of 13 mpg city, 17 highway and 14 mpg combined on the required premium fuel. The 21.6-gallon fuel tank should allow around 300 miles of driving.

2021 Jeep Wrangler Overview

The Rubicon 392 is plenty potent, but it’s not the torque monster of the Wrangler lineup. Instead, that honor goes to the new 4xe hybrid Wranglers with a combined engine and motor peak torque of 470 foot-pounds at 3,000 rpm.

There are a dizzying 14 trim levels of Jeep Wrangler in two- and four-door body styles with five choices for a powertrain.

Engine choices include a 270-hp 2.0-liter turbocharged four-cylinder engine. The 285-hp 3.6-liter Pentastar V-6 has mild-hybrid e-Torque technology. And the 260-hp 3.0-liter EcoDiesel churns up peak torque of 442 lb.-ft. from 1,400-2,800 rpm.

Cutting new trails are the 4xe hybrid Wranglers (and Grand Cherokee 4xe).

The Jeep Wrangler Sahara 4xe and the Jeep Wrangler Rubicon 4xe Launch Editions have starting prices of $49,490 and $53,190, including the freight charge. Pricing does not include the available $7,500 federal tax credit or other eligible state and local credits.

The Wrangler 4xe powertrain is a 375-hp turbocharged 2.0-liter four-cylinder with a combined torque rating of 470 lb.-ft. at 3,000 rpm. That’s a lot of launch power, and it’s still capable of an estimated 50 MPGe, Jeep claims, with an electric driving range of 25 miles.

The 470-hp 6.4-liter Hemi V-8 can launch the Rubicon 392 to 60 mph in 4.5 seconds.

Rubicon 392 Pricing

The production version of the Wrangler Rubicon 392 Launch Edition went on sale this spring. Pricing starts at $74,995, including the $1,495 freight charge from Toledo, Ohio. But finding one can be disheartening. Pricing for those typically starts at around $90,000.

My Firecracker Red tester had a sticker of $78,545 with such extras as the tow package ($350) and trail-rail system ($195). The biggest add-on was the $2,000 Sky One-Touch Power-Top. The clear-coat paint is $245.

The Rubicon 392 is the most capable Wrangler ever, Jeep says. It is off-road ready with the Selec-Trac two-speed transfer case, full-time four-wheel drive, and 10.3 inches of ground clearance. Its heavy-duty wide track Dana 44 axles have Tru-Lock electronic locking differentials and electronic front sway-bar disconnect.

Chassis upgrades include a 2-inch lift and FOX high-performance shocks.


  • The functional hood scoop connects to a tri-level Hydro-Guide air intake. The system feeds the V-8 with cooler outside air, and a one-way drain in the air-box separates up to 15 gallons of water a minute. The Rubicon 392 can ford water up to 32.5 inches deep — even if a bow wake washes over the hood.
  • Active dual-mode exhaust engages automatically to open valves in the exhaust system. Under higher engine loads, the open exhaust reduces back pressure. The driver can also activate the system manually.
  • Chassis changes include heavy-duty brakes, a 2-inch factory lift, upgraded frame rails, and specially calibrated suspension geometry with FOX high-performance shocks.
  • Low-speed descents use engine braking, a revised torque converter lockup control, and a 48:1 crawl ratio. The system allows the driver to manage vehicle speed without using the brake pedal.
  • Four-wheel-disc braking has 12.9-inch vented front rotors with two twin-piston floating calipers. Rear brakes have 14-inch vented rotors with two single-piston floating calipers.

Inside the Rubicon 392, the interior includes leather-trimmed upholstery with bronze Rubicon 392 stitching. The leather-wrapped, performance steering wheel includes paddle shifters, a first for the Jeep Wrangler.

The Uconnect system projects on a standard 8.4-inch screen. The system includes Jeep Off-road Pages that allow owners to monitor such elements as pitch, roll, altitude, GPS coordinates, and drivetrain power distribution.

Other features include:

  • Body-color hardtop and fender flares;
  • HD electrical switch bank;
  • Steel bumper package;
  • Cold weather package;
  • LED lighting package;
  • Remote proximity entry
  • Safety Group and Advanced Safety Group

Why buy the Rubicon 392?

A big Hemi V-8 might not be necessary in an off-roading Wrangler. But the more relevant question from Jeep and Mopar disciples might be why not? The V-6 can feel underpowered on the daily commute. The EcoDiesel engine can level mountains off-road, but it can be snoozy for quick power around town.

The Hemi bloodline runs deep among the Stellantis brand’s loyal owners. And placing this engine in a Wrangler teases the question of when will the Gladiator pickup get one.

For every hybrid Jeep 4xe sold, there will be one more gallon of gas for the Rubicon 392.

Pricing is the great separator. How many $90K Jeeps can be sold? Be prepared if you take a test drive. The Rubicon 392 is a charmer, and the devil on your right shoulder will want you to bring it home. The handwringing angel on your left will remind of your social responsibility and how much more rational it would be to own a Wrangler 4xe.

If you listen to that angel, you will spend the rest of your driving days remembering what you could have been.

Just wait, Jeep will make more and you won’t have to pay a hefty price premium.

2019 Jeep Wrangler Rubicon review

The redesigned Jeep Wrangler JL is tougher and softer in all the right ways making it the best performing Wrangler since the 1986-1995 YJ

T the Jeep Wrangler has long been forgiven for everything that made it a charming pain in the rough. But now, the redesigned 2018 Wrangler is a charmer, off-road or on main street. And the top-line Wrangler Rubicon is a standard-bearer of advanced technologies with its first use of a 48-volt mild-hybrid electrical system.

The 2018 redesign steered this symbol of “Don’t tread on me” from the endangered specie’s list, threatened by ever-increasing clean-air standards for engines and new safety regulations.

It is tougher and softer, in all the right ways making it the best performing Wrangler since the 1986-1995 YJ model with square headlights. The windshield still folds (with greater simplicity), the doors can still be removed and there’s still a manual hand-brake lever on the shifter console. But as with all new cars, it is the electronics technologies that are almost the bigger story of the redesign.

There are new engines, including a turbocharged four-cylinder with mild hybrid technology and an upcoming four-cylinder diesel in 2020. And the carryover V-6 is still the base engine.

The redesigned Wrangler still waves the flag of ‘Don’t tread on me.’

The JL Wrangler

Experienced Jeepers will know this new Wrangler, codenamed JL, from the first slam of the door. That’s when they will realize the doors don’t need to be slammed. And more soundproofing allows occupants to have a conversation without shouting — and that’s with the top up. There is still a mild maelstrom at highway speeds in the soft-top cabin, but it’s about a hundred decibels more tolerable.

The cockpit and driver area were completely reconfigured for a somewhat ergonomic arrangement. There are several stash areas and device-charging ports.

An over-shoulder view of the back seats.

Even the two-door’s ride quality has been tamed.

Even the two-door’s ride quality is not a fearsome bucking bronco. The wider track lets the short-wheelbase model seem more free-wheeling and stable. And there is a much tighter turning circle now. Tighter turning is an asset off-road, but it is just one more engineering feat that makes the Wrangler ideal for the city, too.

The new boxed frame is much stiffer, which helps for stability when teetering among boulders or slogging through a highway commute. For anyone who knew a previous-generation Wrangler, refinement is not a word associated with any part of it.

Drafty, noisy, and rough riding were accepted parts of the lifestyle, but now we see that those qualities are not intrinsic to the concept.

The driver area of the new WranglerRubicon equipment includes remote locking, push-button ignition, rearview camera, and an 8-speaker Pioneer audio system.

Jeep Wrangler Pricing

There are three garden-variety levels of Wrangler in two- and four-door Unlimited models plus the trail-agility-champion Rubicon, and all have various levels of four-wheel drive.

Starting prices range from $29,440 for the entry two-door Sport to $39,790 for the four-door Sahara Unlimited. The top-line Rubicon starts at $39,440 and $42,940 two-door or four-door. Pricing includes the freight charge from Toledo, Ohio.

Big disc brakes on the Wrangler test vehicle.

Braking is considerable from the large four-wheel discs.

Heavy-duty hardware

The two-door Rubicon tester was $49,555. That’s big money for a two-door Wrangler, but this one was the pinnacle of the line. It included  Jeep’s most capable four-wheel-drive system with stability and rollover-mitigation controls.

The Jeep Wangler tester also was equipped with heavy-duty, third-gen Dana 44 solid axles front and rear with Tru-Lock electronic locking. The high- and low-range Rock-Trac transfer case has a manual shift lever at the console and a 4.10 gear ratio. Hill-start assist is beneficial for controlled trail ascents or descents.

Braking is considerable from four-wheel vented discs. The front rotors are 12.9 inches with twin-piston calipers. The 13.4-inch rear discs have a single-piston caliper.

The Wrangler tester had heavy-duty Dana 44 solid axles

There are heavy-duty Dana 44 solid axles front and rear with Tru-Lock electronic locking.

Front and rear sway bars disconnect for more wheel travel. Gas-charged, multi-valve monotube shock absorbers help manage its husky 4,175-pound curb weight.

But being a Jeep means there is much heavy steel in the frame, differentials, and suspension. There are four steel skid plates to shield vulnerable elements such as the fuel tank, four-wheel-drive transfer case, and transmission). And tubular steel rock rails at the frame edge are a trail-riding essential. 

Compensating for some of the Jeep Wrangler’s curb weight are high-strength aluminum doors, hinges, hood, fenders, windshield frame, and a magnesium swing gate.

Jeep Wrangler Powertrains

Fuel economy has never been a selling point for the upright Wrangler shape. The 285-hp, 3.6-liter V-6 (with auto stop-start at idle) still can be ordered with a six-speed manual transmission. It has mileage ratings of 17 mpg city, 23 highway 19 mpg combined on 87 octane. Two-door models have an 18.5-gallon tank and four-door models have 21.5 gallons.

Upgrading to the 270-hp, turbocharged and direct-injection 2.0-liter four-cylinder and the eight-speed automatic is a $3,000 upgrade. But it brings fuel economy ratings of 23/15/24 mpg; premium fuel is recommended but not required. And while the fuel economy isn’t a huge incentive, the power and acceleration can be brisk.

A rear three-quarters view of the 2019 Wrangler

The two-door Jeep Wrangler Rubicon tester was $49,555 with many ‘on road’ conveniences.

eTorque technology

The new engine has Jeep’s so-called eTorque technology. The system applies hybrid functions of auto stop-start at idle, electric power assist, transmission shift management, intelligent battery charging, and regenerative braking. The engine and fuel flow can be turned off during stops, coasting, or when the engine is decelerating.

The electric motor gives a boost to the engine to get the rig moving and to smooth out shifts, Jeep says.

But inching forward for a foothold on a boulder might still require accelerator finesse to raise revs while awaiting the turbo to hit the peak 295 lb.-ft. torque at 3,000 rpm.

The 3.0-liter EcoDiesel engine (also with auto stop-start at idle) will be available in 2020 as an upgrade for four-door models. The engine has 260-hp but 442 foot-pounds of peak torque at a low 2,000 rpm and an eight-speed automatic.
