Jeep Wrangler Rubicon 392 Production Details Announced

Wrangler Rubicon 392 packs 470 horsepower, offering incredible performance on and off-road.

Earlier this year, Jeep introduced the Wrangler Rubicon 392 Concept. It had a very production-friendly look with a 450-horsepower, 392-cubic inch V8 under the hood. It looked like the V8-powered Wrangler that the community has been pleading for and today, Jeep announced that the 450-horsepower concept is becoming a 470-horsepower production reality.

The Jeep that will go on sale early in 2021 is practically identical to the concept with the exception of a bit more horsepower and torque. As a result, it is the quickest and most powerful production Wrangler ever, but it offers the incredible acceleration numbers without compromising any off-road abilities. In fact, the V8-powered Rubicon is modified to offer even greater off-road capabilities, making the Wrangler 392 the overall best performing vehicle on the market today.

392 Hemi Power in a Wrangler

The most important aspect of the 2021 Jeep Wrangler Rubicon 392 is the 6.4-liter, 392-cubic inch Hemi V8 which delivers 470 horsepower and 470 lb-ft of torque.

This is the same basic engine as the one offered in several SRT products, incluing the Grand Cherokee and the Dodge Durango, Charger and Challenger. Like those models, the Wrangler Rubicon 392 has an active dual mode exhaust system that has valves which automatically open under hard throttle, but unlike the SRT products, this Jeep has a switch on the dash to activate the system.

Where the 392 in the Wrangler differs vastly from the other models is the engine air intake system, as this is the first vehicle with this Hemi to be designed for off-road use. The Rubicon 392 features the Hydro-Guide engine air intake system, which includes a functional hood scoop, a three-level filtration system that can remove up to 15 gallons of water per minute and a secondary intake port under the hood.

The power of the Wrangler Rubicon 392 is sent to the grounds by means of a ZF 8HP75 8-speed automatic transmission with paddle shifters, a Selec-Trac two-speed transfer case and a pair of Dana 44 axles with 3.73 gearsets. This full-time four-wheel-drive system features Tru-Lok electronic locking front and rear differentials and when the Off-Road Plus drive mode is active in 4-High, this Rubicon will reach high speeds with the rear axle locked.

BFGoodrich KO2 All-Terrain tires measuring 33 inches are standard on this new Jeep, wrapped around 17-inch beadlock capable wheels. Even though these tires are the furthest thing from an on-road performance tire, the Wrangler Rubicon 392 will sprint from a stop to 60 in 4.5 seconds while covering a quarter mile in 13 seconds flat. The top speed is electronically limited to 99 miles per hour due to the speed rating of the off-road tires, but it is crazy quick from a stop and we imagine that it will offer similar performance in the dirt.

Patrick Rall

"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.

"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.

"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.

"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.

"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.

"Being based on Detroit," says Rall, "I never miss the North American International Auto Show, the Woodward Dream Cruise and Roadkill Nights, along with spending plenty of time raising hell on Detroit's Woodward Avenue with the best muscle car crowd in the world.
