News > Jeep introduces 6.4-litre V8 Wrangler Rubicon 392 Concept

The last time one of the most iconic vehicles on the market was upgraded to a V8 engine was the 1981 Jeep CJ. Its 5.0-litre V8 delivered 125 horsepower and 220lb of torque ensured a powerful drive. Jeep fans have been insisting on a V8 engine for the Wrangler and the Jeep Wrangler Rubicon 392 Concept is making those wishes come true.
The Wrangler Rubicon 392 Concept is powered by a 4-liter (392 cubic-inch) V-8 engine that ensures 450 horsepower and 450 lb. of torque; going from 0-60 mph in less than 5 seconds. The 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 2-inch lift kit from Mopar with suspension enhancements, a more-robust 8-speed transmission, and a V-8 powerplant will give drivers a ride that fun to drive and has even more off-road capabilities than ever.
Jim Morrison, Head of the Jeep Brand in North America states that fans have been asking for a Wrangler V8 for a while and the new Wrangler Rubicon 392 Concept gave them the ability to make it happen. From the recently launched 29 mpg Wrangler EcoDiesel to the Gladiator, as well as the Wrangler 4xe plug-in hybrid electric vehicle, Jeep is taking into account what its customers and fans are saying. Jim adds that they’re excited to see the fans' reactions to the new Wrangler Rubicon 392 Concept and the power its ready to deliver.
Power, speed, and off-road capabilities
The Jeep Wrangler Rubicon 392 Concept features upgraded engine mounts together with a modified frame to accommodate the 6.4-liter V-8 engine and a stronger 8-speed transmission. The suspension upgrades include new aluminium monotube Fox shocks to give an improved damping and heat dissipation. The two-mode exhaust also changes the performance sound with the touch of a button.
It comes with even more off-road capabilities thanks to 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 bead-lock wheels to hold tyres to rims.
A Jeep Performance Parts 2-inch lift kit from Mopar gives additional suspension and an improved approach to angles. It also boasts Rubicon rock rails, steel bumpers with a Warn winch, and a steel belly pan which all help navigate the toughest terrains.
