Selec Terrain mode power distribution

Can someone please point me to or provide the breakdown of power distribution with the Selec Terrain modes?

It was something like:
Snow = 60/40 F/R, tight traction control and stability control
Sport = 40/60 F/R, ESC off
Mud/Sand = ?
Rock = ?

etc. In other words, I want to get clear on what exactly is happening in each mode. Thanks.

Thanks clew. I knew I had seen it somewhere but couldn't recall where.

Trying to keep it simple, there is always 100% power to the front wheels. When the rear axle is engaged the wet clutch pack in the rear differential can go from 0 - 100% engaged giving up to 50 /50 power distribution. It's pretty much imposible to send more power to the rear than the front like sport mode implies. Unless there is a center diff. Which we don't have.

Except Jeep disagrees with your assessment, as they state that up to 100% of torque is available to the rear wheel depending on mode.

The video that clew mentioned shows 40/60 F/R split in Sport and "up to 100% of torque available to the rear" in Mud/Sand mode. What do you make of that? Not possible?

I thought I read a post from someone on this site that stated a 50/50 split in one of the modes (but of course I can't recall which mode -- that's why I'm trying to find it).

100% of torque available to the rear, does not mean 0% of torque to the front. The front wheels are always driven. The rear axle will go to 100% engagement! Meaning both front and rear differentials are fully locked to the transmission output. Only the rear differential is able to reduce the ammount of lock from the transmission output. I think they should have stated, In sport mode the rear axle will go to 60% clutch engagement limiting slip in the drivetrain giving a feel the rear wheels are helping drive the vehicle. Because the front are still recieving 100% from the transmission output, not 40%. This stuff isn't rocket surgury.

Having a hard time following what you are saying...but the only time you are at 100% Fwd is in auto with the rear disconnected.

With Auto mode, the front/rear split varies depending on conditions; most of the time, the Cherokee should stay in front wheel drive for better gas mileage.

Sport limits traction control, increases stability-control slip thresholds, changes the torque bias for better cornering, and allows a target front/rear torque split of 40/60 for a rear-drive feel.

Snow starts in second gear, sets brake controls for slick surfaces, and goes into full time 4x4, preferring a 60/40 front/rear split. Mud/Sand is similar but uses off-road brake controls, and a preferred split of 100% rear wheel drive. Finally, Rock, on Trailhawk only (and requiring 4x4 Low), is similar to Mud/Sand but increases brake lock differential capacity and locks the differential.
