The Jeep Wrangler Rubicon 392 Concept model shows that the production model of a V8-powered Wrangler (and possibly Gladiator) is likely on the way - and that's straight from the people in the know at FCA.

Jeep Wrangler enthusiasts have been asking us for a Wrangler -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."

It's been a hot minute since there was a V8 under the hood of a Jeep. The last model to wear its power proudly was the 1981 Jeep CJ, which had a 5.0-liter V8 that delivered 125 horsepower and 220 pound-feet of torque.

The Wrangler Rubicon 392 Concept is powered by a 6.4-liter (392-cubic-inch) HEMI V8 that delivers 450 horsepower and 450 pound-feet of torque. That power gives the concept a zero to 60 mph time of less than five seconds.

Its engine is paired with a more robust version of the traditional eight-speed automatic, something that the HEMI in the Charger Scat Pack gets as well.

The parts roster includes Rubicon rock rails, steel bumpers with a Warn winch, and a steel belly pan. It also comes with Dana 44 axles, Selec-Track full-time two-speed transfer case (3.73 gear ratio), and Tru-Lok electric front- and rear-axle locking differentials. The SUV rides on custom 17-inch deadlock wheels that are wrapped in 37-inch mud-terrain tires.

The suspension of the typical Wrangler JL has been upgraded to include new aluminum, monotube Fox shocks, and two-mode exhaust, which is adjustable at the touch of a button.

The company has installed a factory Jeep Performance Parts two-inch lift kit from Mopar.

All that equipment gives the model some impressive numbers. It has a water fording capability of 34 inches, 13.25 inches of ground clearance, an approach angle of 51.6 degrees, a breaker angle of 29.5 degrees, and a departure angle of 40.1 degrees. It's Trail Rated.

Jeep has given the concept a Granite Crystal paint job, bronze-colored tow hooks, badging, springs, shocks, and wheels. There's a heavy-duty raised hood, custom half doors, and Wrangler's Sky One-touch powertop.

The concepts interior features a Red Rock-colored leather bolstered seats with gold stitching, along with a performance steering wheel.

When will you see the production version of the V8? These things take time, but remember, the auto show circuit looks to pick up in earnest early next year, and we have the Wrangler 4xe to see first.
