Jeep Wrangler 392 Concept Packs 6.4-Litre V8 In A Rubicon Trim

Jeep has put a V8 engine in the Jeep Wrangler again, and not just any V8.

  • The Jeep Wrangler Rubicon 392 concept packs a massive V8 engine good for 450 horsepower and 450 pound-feet of torque

  • It will hit 60 mph (97 km/h) in under 5.0 seconds

  • Also includes Dana 44 axles, two-speed transfer case and other Rubicon goodies

The Jeep Wrangler 392 Rubicon Concept was introduced this morning by Jeep, bringing massive power to the most rugged Wrangler trim.

After teasing the Wrangler 392 over the weekend, Jeep unveiled the details today. It is powered by a 6.4-litre V8 with 392 cubic inches of displacement (obviously) delivering 450 horsepower and 450 pound-feet of torque. That’s enough to power the Wrangler 392 to 60 mph (97 km/h) in under 5.0 seconds.

That type of performance is often synonymous with track cars, not off-road vehicles. Still, Jeep being Jeep, they decided the best place for a 450-horsepower V8 was in the most rugged Wrangler model of all, the Rubicon.

That means that along with the impressive power comes a 4×4 system, Dana 44 axles, full-time two-speed transfer case, front and rear-axle lockers, a factory lift kit from Mopar, and 37-inch tires. We’re not too far away from the Jeep Gladiator Maximus in terms of rugged performance.

This isn’t the first V8 the Jeep Wrangler has ever gotten, but it certainly is the most powerful. The 1981 Jeep CJ has a 5.0-litre V8 with 125 horsepower and 220 pound-feet of torque. Oh, how the times have changed.

“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.

The Jeep Wrangler 392 Rubicon concept also gets an aluminum monotube Fox shocks, a beefier 8-speed automatic, and a performance exhaust that can be switched to loud or louder, essentially.

Now, we mustn’t forget that this is a concept vehicle, but the press release said that those who have been wanting a V8 in the Wrangler “may soon get their wish”.

Coincidence that Jeep unveils its 392 Wrangler concept on the day Ford is about to release the Bronco? I think not.
