Snow Day with the L

[MTMark]

Went up in the mountains with my Jeep. Snow mode worked great until the snow got deeper and it seemed to get bogged down. Mud/sand mode worked better in deep snow since traction control was not slowing the engine down.

why does the right side amber marker not seem to extend all the way as the left side?

?? I hadn’t noticed that. Interestingly, when I looked at the camera (phone camera), the amber lights looked like they were flashing and when I look with my eyes, they weren’t flashing. Maybe it has to do with the camera??

The camera makes it noticeable, but it's not a defect. LED lights often use PWM (pulse width modulation) to control brightness and dimming. The frequency of this modulation becomes more evident on camera as the frame rate of the videos differs from the frequency of the PWM. As a result cameras will capture frames in an off cycle, which when played back looks like a strobing effect.

Edit: Still photos can capture the off cycles to, and result in artifacts like the one in this photo.

I have to say, though, that in this glamor shot, the front end of the Jeep looks pretty tough.

LED's look funny on camera unless you use a slow shutter. If you watch shows like Top Gear, it's very common (on video) to see the lights flashing/shimmering because the shutter speed on the camera is essentially faster than the refresh rate on the recording. The same can happen with still photography. (source: I earn my living as a photographer)

When I use Auto mode, is my car drive on rear-wheel or fron- wheel?

The GCL is a rear-wheel drive when in 2wd. Auto can engage the 4WD if the system detects wheel slippage and needs it.

Yup. I see it all the time when my wife pulls in the garage on the camera system. It’s like trying to take a picture of a led screen. They all look funny.

WHAT? I don't see ANY ability to put this in 2x4 mode. It's AWD, period, on my Overland. As far as I'm aware, all of these are either AWD or 2WD???

On the jeep website there’s are 2x4 and 4x4 option when selecting and configuring any trim. So no AWD

@Sarge The 4WD drive system has a front-axle disconnect system which is used to improve fuel efficiency, and the vehicle operates as a RWD when the 4WD is not engaged. In auto it can quickly (sub-second) engage the front axle if it needs too.

@Moj You are correct. It's not AWD, it's a true 4WD system, and even more so if you have the eLSD since it can direct up to 100% of the torque to the wheels which need it.

No, it is a split system 52% to the rear and 48% to the front. It's more like a AWD system.

Is it not a Torsen center diff, operating in full time AWD? That was my understanding. If you have the eLSD it will act to prevent wheelspin, and also thwart 'drifting' or sliding, but shifting torque to the inside wheel, etc.
