For latest awd, the difference is small
unless live in t snow belt or lots of offroad
no need for awd

awd里面其实full time比on demand要好，更稳。据说现在最新的有那么几个on demand
也不错，不过我没开过。油耗就差那么一点，没什么区别。不过这种awd都是公路驾驶
用的，提高稳定性。
要越野走unpaved的话就买4wd。可以自己选择两轮跑还是4轮跑。但是4轮跑不建议在有
路面的地方长期开，或者说高速行驶。 |

发帖数: 5514 | 5 全时四驱也要看的，区别很大，有的车是default 前40%后60%分配，有的车是前10%后
90%

发帖数: 5514 | 8 你哪里看到的？我刚在稍微搜了一下, Durango 用的Quadra-Trac AWD default 是前0%
后100%，这个解释了为啥和后驱版MPG几乎没区别。V6和V8车版本四驱系统唯一区别是
V8多了一个low range gearing

"The ITC (Integrated Transfer Case) is a single-speed transfer case. It
provides convenient full-time 4-wheel drive. The transfer case operates with
an open center differential dividing engine torque 50 percent torque to the
front axle and 50 of torque to the rear axle. The Brake Traction Control
System, which combines standard ABS and Traction Control, provides
resistance to any wheel that is slipping to allow additional torque transfer
to wheels with traction. The MP2010 single-speed transfer case provides the
following benefits: •No shift lever or driver interaction required. &
#8226;Full-time 4-wheel drive provides smooth operation and vehicle
stability under all conditions because torque is constantly being
transferred. •Torque distribution provides traction to maintain
forward motion under most conditions. •The Brake Traction Control
System (BTCS) works in tandem with full-time 4 wheel drive. BTCS provides
resistance to any wheel that is slipping to allow additional torque transfer
to wheels with traction. •Robust design and improved sealing enhance
reliability. Engine torque is continuously split 50/50."
So in the V6 at least, there is no bias and no transfer(front to back). It's
50/50 all the time.
The only transfer would be side to side via the traction control, the split
will remain 50/50(front/back) regardless of traction or wheel spin.
Not sure how much different the Hemi is, you could e-mail Chrysler and ask
like I did. Took them about 2 weeks to get back to me.
