Why Diesel Gladiator towing capacity will be less than 3.6L Pentastar models

[RedTRex]

Since the only Gladiator that is rated to tow 7,650# is the Sport S w/ Max Tow, does this mean the Ecodiesel will also be offered in the Sport S?

NO!!!!!!!

Careful though, because payload affects tongue weight and tongue weight affects maximum towing. And, the diesel will only be offered in the models with the worst payload numbers. So, the diesel may end up being confined to much more than a 500 lb difference if you've also got things on/ in the truck.

And yeah, it'll get better MPG towing, but it's doing it on fuel that's $0.60/gal more expensive.

Not around here, it's about the same as 93 if not cheaper. For example this morning I filled up the Vette at a Gate station with 93 and it was $3.19......Diesel was $2.95

Is that also part of the reason why a manual transmission tows so much less than auto? I'm buying this truck for sure, but was happy to be going back to driving stick before I saw the tow difference. I wanted at least 5000 lbs for horses and hay.

Also, I know sales/delivery is Q2 2019, any indication when we can actually start ordering?

They say the discrepancy between auto trans and manual is a clutch issue... that the computer/auto trans puts less stress on the clutch than humans, so, for safety allowances, they have to rate it for less.
I’m also using my Glad Rubi for a ranch truck... hauling horses, hay, and stock! My ranch is in the mountains of Northern New Mexico, and it’s a real pain in the butt to get my full size 4x4 truck where I need it to go! For years I’ve dreamed of Jeep resurrecting their pickup line! Been using my little 4L straight six TJ to trailer into rough country for the last ten years! Can’t wait for my Rubicon Gladiator to come so I can retire “Lil’ Buck”! ;{

Yea here in Idaho is basically the same right now. During winter its about $0.30-$0.75 more. So you both are right

Meh. Sitty cent...

That's what the aftermarket is for.

Interesting how these threads can go all over the place on conversation. And I just lifted, wheels and tires on mine from my personal friend that owns a tire shop. He informed the stripping of diesel emissions is getting radical enforcement in the Virginia Maryland and Washington DC area. Their is a local off road company that has many locations and had been in business for 30 plus years. They have been caught by the EPA removing diesel emissions on trucks and tuning as well. They apparently have settled out of court for half the fine but the local Virginia State Police now require repair shops to inform them of any Emissions tampering....wow the good old BIG GOVERNMENT is on a mission for the ICE AGE.

As an engineer and a Jeeper. I would rather have the 6v etorque system. All the benefits of diesel and so much more. I would trade in my just ordered LE in a sec for that option.

+1 for eTorque!

being that it's Virginia Maryland and Washington DC area does not surprise me.

Curious about one thing on cooling here.

The Grand Cherokee Ecodiesel is rated to tow the same as the hemi 7200 pounds if the sites i checked stated correctly.

Jeep engineers seem to suggest that they need more grill opening to go any higher on tow rating for the JT. If the JT is restricted on going above 7100 ish with out additional airflow through the grill, how the heck did they pull off 7200 on the grand cherokee?

Looking at our cherokee, it has around half the grill opening of the JL/JT. Grill is roughly the same width, vertical bars aren't as wide, but the vertical dimension of the opening is about half that of a JL. Look at some pics and compare the openings when the car has a front license place for reference.

I find something suspect here. I bet there is another reason beyond cooling that they underrated the diesel for towing.

Noob question, so if I wanted to order a si

In the case of the manual trans, hardware capacity also comes into play. Today's automatics are much more robust than manuals. In order to do a manual with a 7,650 tow capacity they'd have to select a different clutch and that would increase pedal effort in order to keep costs in check, and they'd also need to greatly beef up the transmission itself. I consider us to be lucky we even got a manual transmission at all for the new model.

What do you mean by beefing up the transmission? I was set on getting a JTR in the near future but planning on going manual. I’d like to have decent enough towing capacity to tow a boat. (don’t know which type or how long yet either)

They basically said the manual transmission isn't designed to tow over 4,000 lbs. because of the clamping force of the clutch they are using. They've designed it to have very light pedal effort, which makes it more enjoyable to drive daily. But the flip side of that is the pressure plate on the clutch doesn't have a lot of holding force, so if you towed a really heavy load you'd risk slipping the clutch and wearing the friction disc down prematurely.

I would guess that the grand cherokee has more room in the nose for a bigger radiator.

The Grand Cherokee isn't a brick moving through air trying to pull another 7,000lbs behind it.

Well that sucks! I was looking forward to having a six speed again and being able to tow a decent boat as well. Thanks for the info @WXman
