It took almost 40 years to overhaul a V8 engine under the hood of a Jeep, that is, since 1981, the year of the CJ equipped with the 5-liter unit. At the time, the CJ's V8 engine developed 125 horsepower, while the 6.4-liter V8 of the current Rubicon even reaches 470. The Rubicon 392 receives specific details, such as the steering wheel with aluminum elements, the Performance seats and the Rubicon lettering with bronze colored thread.
