Grand Cherokee ZJ 1993-1998

Equipped with one of the following four wheel drive systems:

  • Command-Trac - part-time all wheel drive with shift-on-the-fly possibility (used until 1996). 2.72 low range.
  • Selec-Trac - selectable all wheel drive. NV242 transfer case.
  • Quadra-Trac - full-time all wheel drive system. A viscous coupling locking center differential.

In 1993-1995 the viscous coupling was used to lock the differential when in low range (NP249 transfer case). In 1996-1998 the differential is mechanically locked when in low range (NV249 transfer case).

Grand Cherokee WJ 1999-2004

Equipped with one of the following four wheel drive systems:

  • Quadra-Drive
    • automatic all wheel drive (standard on "Limited", optional on "Laredo"). Normally rear-wheel drive vehicle. The differential is the hydromechanical system based on geroter oil pump and clutch pack, located within the transfer gearbox between the driveshafts that carry power to the front and rear axles. One part of the pump, the rotor, is driven by the front driveshaft while the other part, it's case, is attached to the rear driveshaft. The system reacts faster than the viscous coupling unit of the previous Jeep AWD system. The reaction time is about 40 milliseconds. The transfer box can be also locked in low-range mode to provide equal power to the front and rear axles.
    • Progressive Vari-Lok gerodisc differentials front and rear, using the same geroter pump system. Almost 100% of torque can be transferred to any wheel.
    • NV247 AWD transfer case with lever-operated 2.72:1 low-range gear.
    • Dana 30 non-disconnect live axle at front, aluminum central section Dana 44 at rear.
  • Quadra-Trac II
    • automatic all wheel drive. NV247 transfer case. The same as Quadra-Drive but without the Vari-Lok differentials.
  • Quadra-Trac I
    • automatic all wheel drive. NV140 - a version of the NV247 transfer case lacking neutral and low-range modes (2004 only).

Grand Cherokee WK 2002-2010, Commander XK 2006-...

Equipped with one of the following four wheel drive systems:

  • Quadra-Drive II - full-time all wheel drive system. 48/52 percent torque split (front/rear). Electronically-controlled multi plate clutch proactively locks the center differential. 2.72:1 low-range mode. Electronic Limited Slip Differentials (ELSD) front and rear. ELSD is the Eaton EGerodisc - a hydraulically-operated electronically controlled limited slip differential that is capable of providing variable torque up to full axle lock:

  • Quadra-Trac II - Same as Quadra-Drive but without the ELSD. Instead, an electronic traction control - Brake Traction Control System (BTCS) - is used to transfer torque from left to right.
  • Grand Cherokee SRT8 2006-2009

proactive automatic all wheel drive. In normal conditions, 100% of torque is transferred to the rear axle. This system is sold under the name of Quadra-Trac I, however it is not a full-time all wheel drive, as on the other Grand Cherokees.

Jeep Compass (MK) 2007–present

  • Freedom Drive I
  • Freedom Drive II (European version) - available with either a CVT gearbox or most commonly with a 6-speed manual gearbox

two settings on the traction control and electronic stability program systems to cater for off-road activity, U.S. FDII suspension travel and a full-size spare tire. Skid plates and tow hooks are options in the EU, but the hill descent control system is not available.
