To help it accommodate the extra power that V8 delivers, the Wrangler Rubicon 392 Concept features upgraded engine mounts and a modified frame.
The wait for a V8 engine in a Jeep Wrangler Rubicon is finally over.
The engine's outputs are sent to a TorqueFlite eight-speed automatic transmission with steering wheel-mounted paddle shifters, while its off-roading capabilities are aided by a two-speed transfer case and full-time four-wheel-drive, heavy-duty wide-track Dana 44 axles with electronically locking differentials, and front sway bars that can be electronically disconnected from the cabin. Even after the heavyweight and boxy SUVish design, the Jeep Wrangler Rubicon 392 can sprint from 0-100 kmph in just 4.5 seconds.
Like the concept, the new Rubicon increased its ride height by two inches. Suspension upgrades include new aluminum, monotube Fox shocks for improved damping and heat dissipation. As standard, it is equipped with 33-inch wheels mounted on 17-inch wheels, and Jeep says it improved the attack and departure angles. It has Dana 44 front and rear axles, with thicker tubes, for hard off-road situations, electronic locking differentials and electronic disconnect for the front stabiliser bar. And if that is not enough, Jeep also claims that the new Rubicon can generate nearly all engine torque at lower RPMs, to allow a smooth ride over the rough terrain. The new Wrangler Rubicon comes with an optimized grille, which is actually necessary to cool that power-packed V8 engine and the power-consuming new instrument cluster in the cockpit.
In all likelihood, the production model will be mechanically identical to the Rubicon 392 concept. The SUV also gets several other standard features like leather upholstery, infotainment group, advanced safety, and body-coloured hardtop. Wrangler Rubicon 392 is two inches higher off the ground than the original design, which allows better road performance when driving up steeper slopes and going through 2.7 feet of water.
