The Command-Trac has formed a base for the Selec-Trac and Quadra-Trac systems. In principle, it works like the Command-Trac system, but it has a few extra solutions, as mentioned above. Rock-Trac is the hardcore version of Jeep’s 4x4 systems. Naturally, it is “Trail Rated,” and it has a brake lock differential. The latter allows for impressive off-road abilities and is only found on this system.Īdditionally, it comes with an NV241 OR transfer case, which provides a 4:1 low gear ratio. It has locking differentials with electronic actuation and offers an electronic front sway bar disconnect function (introduced in 2007). This system comes standard for the Wrangler/Wrangler Unlimited Rubicon. Its transfer case comes with a shift-on-the-fly system, and users can opt for a neutral range for flat towing, or a 2.72:1 Low range, used for extreme off-road situations.ĭifferent variations of this system are in use today, and you can find the Command-Trac on the Wrangler/Wrangler Unlimited Sport, Sport S, and Sahara Trims. It is recommended for wet/slick surfaces, extreme weather, and off-road activities. It is a classic 4x4 solution, and it is so hardcore it cannot operate in 4WD mode on high-traction surfaces, like dry pavement, because it would suffer excessive wear as it does not have any differential action in the transfer case. The name Command-Trac dates back to the 1980s. The crawl ratio is maintained and the system also benefits from Jeep’s “Trail Rated” guarantee of off-road performance. It represents an evolution of the Active Drive 2 and features an extra mechanical real axle lock. The Active Drive Lock comes as standard for the Cherokee Trailhawk. It also offers a “neutral model,” used for flat towing. Unlike the one on the Renegade, this one has a 56:1 crawl ratio. The Active Drive II can be had on the Latitude and Limited versions of the Cherokee and comes with a low-range function. The system works just like on the Renegade 4x4, but has a different name. Meanwhile, Active Drive I is only offered on the Cherokee. The first of these features a low-range switch, and it's only available for the Renegade Trailhawk. It comes in versions like Active Drive Low, Active Drive I, Active Drive II, and Active Drive Lock. This system is an all-wheel-drive solution, and it has several operating modes to enhance its capabilities. If a slip is detected in the front wheels, the rears get power until the speeds are matched. This system requires no input from the driver, and it comes with a set of sensors that determine whether to send power to the rear wheels or just to the front axle. We will start with the Active Drive system, available on the Jeep Renegade and the Cherokee. All-Wheel-Drive Systems for Cherokee and Renegade Except for an off-road fanatic, an all-wheel-drive system should be just fine for the regular user.
In extreme off-road conditions, 4WD beats AWD any day, but each system comes with a set of advantages and disadvantages. You can buy a Jeep with an all-wheel-drive system and order an improved 4WD solution for certain engine versions, but this applies only to some models in the range. Naturally, some models do not come with a 4WD system, but have all-wheel-drive, while the opposite is true for other Jeep cars. Jeep sells both systems, but they are marketed differently. In spite of doing the same thing as 4WD in theory, all-wheel-drive is not as well-suited for off-roading as a conventional 4x4 system. Since it is controlled by a computer, it allows the automaker to customize the way power is delivered to the wheels, and to fine tune how the vehicle handles. Meanwhile, all-wheel-drive is almost always on and typically sends power to all four wheels. If you are looking for an off-roader, it's safe to say that you need something with 4WD.
