大切诺基的三种四驱系统有什么区别啊，
大切从Laedo到srt有三种四驱系统
Quadra-Trac II active 4WD system
Quadra-drive II 4WD system
Quadra-Trac * Active on-demand 4WD system
有什么区别啊
求普及

第一个应该是可以手动激活，也就是所谓的锁定四驱，第三个应该是适时四驱，就是会自动调节根据环境，当中应该就是普通的四驱吧。。。

呃，求更清楚的解释啊
楼上这么说还是没明白啊

不是二楼不明白，是lz完全没做功课，从头解释起来是比较难

lin181105418

呃，还是有做一些功课的啦，
知道是一二两种驱动是在后桥的开放式差速器和多片离合器式限滑差速器的区别，第三种只在SRT上用，就不说了（不会买那种）
那在实际使用中会差别多少呢

QUADRA-TRAC II® 4X4
Capability breeds confidence. The Quadra-Trac II® 4x4 system features a two-speed transfer case that uses input from a variety of sensors in order to determine tire slip at the earliest possible moment and take corrective action. When tire slippage is detected, as much as 100% of available torque is instantly routed to the axle with the most traction. Choose the Auto mode in the standard Selec-Terrain® traction control system for everyday driving or quickly dial in Sport, Snow, Sand/Mud or Rock for specific driving conditions. Go boldly.

Quadra-Trac II® is an active, full-time 4x4 system that functions in 4WD until additional traction is needed. It then reacts by electronically engaging the clutch pack to transfer up to 100% of the torque to either axle. The system works with the Brake Lock Differential and Four-Wheel Brake Traction Control systems to deliver confident all-weather traction. The Quadra-Trac II 4x4 system also features a 2.72:1 low range and neutral for flat towing.


QUADRA-DRIVE® II 4X4 WITH REAR ELSD
The definitive capability statement, the Quadra-Drive® II 4x4 system with rear Electronic Limited Slip Differential delivers superior all-weather traction and legendary Jeep® vehicle off-road capability. Choose the Auto mode in the standard Selec-Terrain® traction control system for everyday driving or quickly dial in Sport, Snow, Sand/Mud or Rock for specific driving conditions. Adding another dimension is the Quadra-Lift® air suspension system—it can raise the vehicle for better off-road capability and lower it on-road for better handling and fuel efficiency+.

The Quadra-Drive® II active, full-time 4x4 system is the ultimate for virtually any driving situation. This system uses the Quadra-Trac II® transfer case with an Electronic Limited Slip Differential in the rear axle, offering excellent tractive performance. Quadra-Drive II also features a 2.72 low range and neutral.

When to use:
High range:All road surfaces, including wet or snow-covered pavement, sand or gravel.Low range:Conditions requiring added low-speed power, technical driving and situations when added torque is helpful (e.g. pulling a boat trailer out of water).
