Jeep adds a V8 under the hood of the 2021 Wrangler Rubicon

With a 4-cylinder turbo, a V6, a diesel engine and a plug-in hybrid version, the Wrangler was already available with a wide variety of powertrains. But according to FCA, part of the clientele demanded the arrival of a V8 engine, in particular off-road enthusiasts, some of whom mounted these engines in their vehicles.

This is now done “officially” with this new Rubicon version equipped with the famous Hemi 392 V8. It is the same engine found in other models of the group, such as the Dodge Charger, Durango and Challenger.

Reworked under the hood of the Wrangler, the 6.4-liter V8 develops 470 horsepower and 470 pound-feet of torque. It is associated with an eight-speed automatic transmission. The driver can change gears using paddles behind the steering wheel or directly at the lever. On the other hand, it will not be possible to opt for a manual transmission with the Wrangler V8. On the other hand, the high and low speed ranges (for off-road) are obviously still available.

The exhaust, also specific, has two different modes. The first is deliberately discreet so as not to wake up its neighbors. The second opens the valves to deliver a harsh and much stronger sound. Jeep engineers started the vehicle in a virtual conference, and the sound quality looks promising!

For the tune-up, Jeep tested its Wrangler V8 on the famous Rubicon Trail, near Lake Tahoe. More surprisingly, FCA also used a drag track to perfect the performance of its 4×4 in this exercise. And we must admit that he defends himself rather well.

Despite the weight to move, the Wrangler Rubicon 392 is able to go from 0 to 100 km / h in just 4.5 seconds! For its part, the quarter mile is dispatched in 13 seconds. In contrast, the typical off-road tires imposed a maximum speed limit of 99 miles per hour, or 159 km / h.

Reinforced chassis and undercarriages

Aesthetically, the Wrangler Rubicon 392 inherits the hood of the Gladiator Mojave whose air intake actually feeds the engine. This allows you to ride in mud and water without risking the engine to suffer.

To support the extra power, torque and weight of the V8, Jeep reinforced the front part of the chassis. The running gear has also been revised accordingly, as well as certain gearbox gears and axles that transfer power from the engine to all four wheels.

The Wrangler V8 rises two inches higher than the normal model. The suspension also has springs adapted to the heavier weight of the engine.

A version reserved for the 4-door Rubicon model

The V8 engine will not be available in two-door models. In the four-door models, the Rubicon version will be the only one to benefit from it. FCA also clarified that the Gladiator will not be equipped with it either.

The Wrangler Rubicon 392 will be available in early 2021 from our neighbors to the south. The dates for marketing in Canada have not yet been communicated.

On the other hand, FCA still hasn’t quoted a price, but there’s no doubt that it should be pretty high since a base V6-powered Wrangler Rubicon already costs over $ 50,000.
