HOW JEEP® 4X4 SYSTEMS WORK
Beholding the power of a Jeep® 4x4 system is, well, something you have to experience as a driver. But, for now, reading will have to suffice (bummer, eh?). There are nine systems in all—each precious in their own way.
Quadra-Trac I ®
The brilliance of this 4WD system is its simplicity. Quadra-Trac I operates in a high-range, all-time mode delivering optimum traction in virtually any driving situation with no driver input required.
NOTE: The Grand Cherokee SRT8® uses the Quadra-Trac on-demand system that drives the rear driveshaft and engages the front driveshaft when needed, either when slip is sensed, or with throttle anticipation, which engages the front prior to slip when throttle is applied.
