The last time a V8 was offered with the Wrangler was the 1981 Jeep CJ with a 5.0-litre engine that produced 125 hp. Over the years, several concept vehicles based on the Jeep Wrangler have featured V8 engines. In July 2020, Jeep has unveiled a new concept that reignites the imagination of enthusiasts who have been clamoring for a V8-powered Wrangler for years.
The Rubicon 392 Concept, appearing almost production-ready, is powered by a 392 cubic-inch (6.4 L) V8 that delivers 450 hp and 450 lb-ft of torque, propelling the off-roader to 60 mph in under 5 seconds. To accommodate its 6.4-liter V-8 engine and a stronger 8-speed transmission, the Jeep Wrangler Rubicon 392 Concept features upgraded engine mounts and a modified frame.
With the upgraded engine output, the 8-speed automatic transmission is strengthened. To maximize its off-road capabilities, the Wrangler Rubicon 392 Concept features third-generation Dana 44 axles, a Selec-Track full-time two-speed transfer case, Tru-Lok electric front- and rear-axle locking differentials, 37-inch mud-terrain tires that wrap around custom 17-inch beadlock wheels that allow for reduced tire pressure operation and added traction.
A factory Jeep Performance Parts 2-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.
