Obviously, I'll believe it's really coming when I see it's really coming but let's just assume for a moment that it is, would you sell what you have to buy it? You know it'll come at a premium, so if the answer is a yes, how much would you be willing to spend to get one? Inquiring minds want to know. :yup:

July 13, 2020 , Auburn Hills, Mich. - The last time the most recognizable vehicle on the planet was offered with a V-8 engine was in the 1981 Jeep® CJ, with its 5.0-liter V-8 that delivered 125 horsepower and 220 lb.-ft. of torque. Jeep enthusiasts have been clamoring for a V-8-powered production Wrangler in recent years and the new Jeep Wrangler Rubicon 392 Concept is an indication they may soon get their wish.

The Jeep brand has introduced its new Wrangler Rubicon 392 Concept, powered by a 6.4-liter (392-cubic-inch) V-8 engine that delivers 450 horsepower and 450 lb.-ft. of torque, and a 0-60 mph time of less than five seconds. Dana 44 axles, a full-time two-speed transfer case, electric front and rear axle lockers, 37-inch mud-terrain tires and a Jeep Performance Parts two-inch lift kit from Mopar combine with suspension enhancements, a more robust eight-speed transmission and the massive V-8 power plant to deliver the ultimate fun-to-drive Jeep vehicle with more off-road capability than ever in a Jeep Wrangler.

“Jeep Wrangler enthusiasts have been asking us for a Wrangler V-8 and our new Wrangler Rubicon 392 Concept proves that we have the ability to make that happen,” said Jim Morrison, Head of Jeep Brand – FCA North America. “From the recently introduced 29-mpg Wrangler EcoDiesel to our award-winning Jeep Gladiator, and the upcoming Wrangler 4xe plug-in hybrid electric vehicle, Jeep is clearly listening to its customers. We are anxious to gauge their reaction to this new Wrangler Rubicon 392 Concept, a vehicle that delivers an incredible and unmatched level of fun-to-drive performance and capability, on- and off-road.”

Power, performance and capability on- and off-road
To accommodate its 6.4-liter V-8 engine and a stronger eight-speed transmission, the Jeep Wrangler Rubicon 392 Concept features upgraded engine mounts and a modified frame. Suspension upgrades include new aluminum, monotube Fox shocks for improved damping and heat dissipation. A two-mode exhaust alters the performance sound at the touch of a button.

The Jeep Wrangler Rubicon 392 Concept boasts even more capability courtesy of third-generation Dana 44 axles, a Selec-Track full-time two-speed transfer case, Tru-Lok electric front- and rear-axle locking differentials and 37-inch mud-terrain tires that wrap around custom 17-inch beadlock wheels that hold the tires to the rims under extreme lateral loads, allowing for reduced tire pressure operation and added traction.

A factory Jeep Performance Parts two-inch lift kit from Mopar makes way for additional suspension articulation and improved approach, breakover and departure angles. The Wrangler Rubicon 392 Concept also features Rubicon rock rails, steel bumpers with a Warn winch and a steel belly pan – all added to help navigate the toughest off-road terrains.

The more robust eight-speed automatic transmission and full-time 4x4 transfer case improve overall drivability, and massive amounts of low-end torque allow for a 3.73 gear ratio, which delivers improved highway efficiency and a greater range of off-road capability.

Enhanced Jeep Trail Rated capability
The Jeep brand boasts several Trail Rated criteria, which are improved on the Wrangler Rubicon 392 Concept, specifically:
Traction is improved courtesy of 450 lb.-ft. of torque and custom 17-inch beadlock wheels
A factory Jeep Performance Parts two-inch lift kit and 37-inch tires combine to improve articulation and contribute to unprecedented levels of water fording capability (34 inches) and ground clearance (13.25 inches), as well as improved approach (51.6 degrees), breakover (29.5 degrees) and departure (40.1 degrees) angles.

Unique, custom design inside and out
The new Jeep Wrangler Rubicon 392 Concept features Granite Crystal exterior paint adorned with Bronze accentuated tow hooks, badging, springs, shocks and wheels, while featuring a heavy-duty raised performance hood with an aggressive appearance, custom half doors and Wrangler’s Sky One-touch powertop, with removable side panels for complete open-air freedom.

Inside, the Wrangler Rubicon 392 Concept features rich Red Rock-colored leather bolstered seats with gold stitching, along with a performance steering wheel.

I would seriously consider it. Not sure I would sell what I have but might add it to the garage.

They would sell like hotcakes.. and I for sure would be on a list to get one. But, like you said.. I'll believe it when I see it. The fact that they announced this the same day Ford is releasing their Bronco is no coincidence. They are worried about their market share.

I will believe it when I see it as well.

If I am in a better position by the time it were to be released, I would be tempted, but it would be a money pit, needing axles right away, and the list goes on.

What compromises were made in the strength of things in order to pass the crash tests, and what will it take to fix the inevitable issues that will follow?

The most likely thing I see there is JL half doors. Maybe we can at least get some of those available 👍

Definitely would believe it when I see it. I'd say it's reasonable to pay another 15k + option to have it installed from factory along with the warranty. You'd be paying far more than that and have the headaches. Only concern would be axles as you start to add bigger tires. But he'll even if they charged 20k more your still probably ahead of the game

Not on 44 axles thank you. Wonder how many warranty claims there would be on these?
Half doors look great though.

Edit: IF this becomes a reality, the Insta-heroes are gonna have a fucking field day with these :rolleyes2:

I tend to keep my vehicles for 8-10 years no matter what new model comes out... 5 years with a payment, 3- 5 years without... otherwise I feel like I’m just pissing money away. So we’ll see how the prices are in 2025. Lol...

If it was available right now and I was in the market... I think anymore than $5k over the 3.6 is robbery.. A swap is 20k + because, well, its a swap.. but factory shouldn’t cost that much. Look at Fords options.. Adding a V8 to the F150 is $2k... adding their premium V6 is $2.5k.. So $5k on the Jeep, considering they don’t sell like fords.. seems fair to me and for sure I would get it... If they start pushing 10-15k more... I’d have to really think about the build and if I was going 40’s with 60’s... I guess its worth it then vs a swap.

Interesting for sure! If money wasn’t a issue I’d sell my JK in a heart beat just so I can have OEM half doors!! LOL


Thank god, half doors finally! And a V8, but who’s counting.

5-10k would be worth it, but it will still need a set of 60s to actually use it. But like the guys said, you’d still be ahead of doing a swap.

It will be interesting to see the dealer mark up on these first couple beasts

A factory V8 with a warranty? However much they want!!

Makes me happy I haven’t pulled the trigger on a gladiator yet. Make it an option in Mojave trim please.

Depending on sticker price i would attempt to sell my 2015 2 door to partially pay for one.But if it doesn't sell then i wouldn't just finance outright.
