The new Jeep Wrangler Rubicon 392 has been unveiled in North America, powered by a whopping V8 engine worth 350 kW and 637 N.m.

Interestingly, the 6,4-litre (or 392-cubic-inch) V8 petrol mill offers more power and torque in the production model than the 336 kW/610 N.m concept that preceded it.

Billed as the “quickest, most powerful Wrangler” yet, the new flagship model features an eight-speed automatic transmission with a full-time active transfer case and paddle shifters. Jeep says the Wrangler Rubicon 392 will hit 60 mph (96 km/h) in 4,5 seconds and complete the quarter-mile run in 13,0 seconds. An active dual-mode exhaust delivers what the company describes as an “exhilarating and unmistakable” sound, and culminates in quad tailpipes.

The Wrangler Rubicon 392 furthermore boasts heavy-duty wide-track Dana 44 axles, a 3,73 final drive ratio, a 50 mm suspension lift (and Fox aluminium monotube shocks) and 33-inch tyres on 17-inch beadlock-capable wheels. The chassis gains upgraded frame rails, front upper control arms and cast iron steering knuckles, while heavy-duty brakes have been fitted, too.

Ground clearance comes in at 262 mm, with the approach, breakover and departure angles listed as 44,5, 22,6 and 37,5 degrees, respectively. Wading depth is an impressive 825 mm.

Inside, you’ll find plenty of leather with bronze stitching along with the company’s latest 8,4-inch Uconnect system.

“This is the most powerful, quickest, most capable Jeep Wrangler we’ve ever built,” said Jim Morrison, head of Jeep in North America.

“The factory lift and abundant low-end torque from the V8 makes the Rubicon 392 the king of the hills, whether you’re rock crawling at low speeds or powering up an incline. And when pavement replaces dirt, Rubicon 392 makes quick work of the road.”
