The GC 4WD/all wheel drive gets about 1 mpg less than if it was a 2WD so not a big loss or savings. I'm not sure but I think the Wrangler being able to go into 2WD has some thing to do with the solid front axle and parts wearing faster if it stayed in 4WD all the time. Now having said all of that the Wrangler Rubicon (ROC-Trac transfer case) has been recently added (last couple of years) a Full time transfer case where it can be run in all wheel drive like the GC on dry road surfaces.THis is off topic but why did they make the GC all time 4 wheel drive and the wrangler able to go in 2WD? Wouldn't the GC get better MPG if it could run in 2 WD
The tech materials and the marketing materials use different names for the same thing—“Quadra-Drive II” is synonymous with “Quadra-Trac II with ELSD.” QDII is therefore standard on Trailhawk and Summit trims, and it would be present on Overlands equipped with the Off-Road package… if you could actually order that.This screenshot of the website promotional material is definitely proof that they cloned previous material. I don't believe the Quadra-Drive II is available on any trim level and certainly not the Quadra-Trac SRT.
This is standard on all 4xe wranglersa Full time transfer case where it can be run in all wheel drive like the GC on dry road surfaces.
So is it technically in 4 hi all time? Or is acting like an AWD car? I read someone said sport mode makes it real wheel drive I don't believe that to be true.This is standard on all 4xe wranglers
On the wrangler 4xe, regardless of trim level, you can run in 2wd, 4 auto, 4 hi, or 4 low.So is it technically in 4 hi all time? Or is acting like an AWD car? I read someone said sport mode makes it real wheel drive I don't believe that to be true.
I have a GC sorry should have mentioned that.On the wrangler 4xe, regardless of trim level, you can run in 2wd, 4 auto, 4 hi, or 4 low.
You can run it in 4 auto all the time on the road. It will generally run with just power going to the rear wheels, but will send power to the front as needed. There's minimal difference in fuel economy (whenever I've tested it, I've found no appreciable difference).
The wrangler originally was not going to have a 2wd mode at all and only be available with 4 auto, 4hi, and 4 low. This is what the 392 gets.
I don't know how the GC handles sport mode.
Thanks for the explanation. Mine has stayed in Auto since a got it besides one time in sport mode to try and burn gas.My experience with Jeep’s is that when running in the 4auto/AWD when the Jeep senses a wheel slipping it kicks in the AWD much quicker than other makes of vehicles. Maybe something like a 1/8 to 1/4 wheel spin whereas other vehicles GM I know especially is more like 1/2 to 3/4 or more before it kicks in. When you have elsd it’s the ultimate to me there’s nothing like it. It’s like the old Jeep commercials “Only in a Jeep”.
It might switch to more rear-wheel bias, but never FULL rear-wheel drive. Sport mode adjusts the mapping of gears a little bit, holds gears longer, and keeps the ICE on in the 4XE which will allow for faster response of full power when the throttle is applied.I read someone said sport mode makes it real wheel drive I don't believe that to be true.
I have yet to floor it. Something I have been itching to do but don't want to break something LOL!It might switch to more rear-wheel bias, but never FULL rear-wheel drive.

Just do it.I have yet to floor it. Something I have been itching to do but don't want to break something LOL!
Thank you. That make sense now.The tech materials and the marketing materials use different names for the same thing—“Quadra-Drive II” is synonymous with “Quadra-Trac II with ELSD.” QDII is therefore standard on Trailhawk and Summit trims, and it would be present on Overlands equipped with the Off-Road package… if you could actually order that.
I tend to drive with the "Power Flow Screen" displayed because I like to see what system is making power and where it's going. I notice that quite often, when the traction loads aren't high and the road is straight, that the power flow shows only the rear wheels engaged.It might switch to more rear-wheel bias, but never FULL rear-wheel drive.

Yes. It can automatically shift power, but Sport mode doesn't force full RWD only mode.I tend to drive with the "Power Flow Screen" displayed because I like to see what system is making power and where it's going.

Axle-y (actually) the front axle can be disconnected - not a process the driver can control but in some circumstances it will. Says on the build sheet: Conv Diff Frt Axle w/ Disconnect. I am sure that it will stay locked if temperature is around freezing, wipers are on, you are in any of those other drive modes, the steering angle is beyond a certain "straight line" margin of error, cruise control is not on,... and so on. Probably says in the manual.It might switch to more rear-wheel bias, but never FULL rear-wheel drive.

While I didn’t floor it I got on it in sport mode over the weekend, Wow! It makes me almost not want to hybrid mode auto anymore.Just do it.
Get the ICE warmed up with a little run around in light sport mode, bring the oil temp up and let it rip.
Even do it from a slow roll when getting on the highway, it's got the get-up and go.
