    When the 3.0L EcoDiesel Gladiator arrives in 2020, it will boast the most torque of any Jeep — at 442 lb-ft of torque. But, the diesel Gladiator won’t reach the full 7650 lbs tow capacity of the 3.6L Pentastar Gladiator. It’s expected to tow approximately 500 pounds less.

    And a big reason reason for that is with more power comes more need for cooling. The larger air cooler unit on the EcoDiesel engine cuts down some of the front airflow coming through the grille, which results in reduced cooling area, which results in less tow capacity.

    Interesting. For me this is yet another reason to stick with the tried and true Pentastar as opposed to the diesel. When towing with my JK in the summer the cooling system definitely gets a big time workout. If the diesel is worse in this regard, I am not interested anymore.

    Also have to wonder if the Pentastar for Gladiator will ever get the BSG version of that engine if they want to maintain this best in class tow rating. As we have seen in the 2.0L in the JL it has even more cooling needs because of the battery.

    Methinks they are going to de-tune the diesel.
    Profound sadness.

    Why does the sport with max towing, tow more, and have more paylod capacity than the rubicon?

    Because the Rubicon is heavier by quite a bit (due to the 4:1 tcase, front swaybar disconnect actuator, etc.), and the larger and heavier tire size on Rubicons. I think Rubicons are heavier by about 350-400 lbs across the board.

    This. And beefier / wider axles.

    It also has to do with weight. Actually, weight is the biggest contributor, which is why the Sport will tow more than the Overland or Rubicon, despite the Rubicon having deeper axle gearing.

    Makes sense. It has to tow itself, and the trailer. So if its heavier to begin with, can't tow as much.

    Works for me. 7000lbs is still plenty

    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?

    So will the diesel be available on all trims? As I thought the Rubicon only towed around 7K

    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.

    It might also have to do with the forward gear ratios of the manual trans they had available, and what RPMs that runs the engine at on the highway under a trailering load. May be a cooling thing. Just guessing tho.

    What he said ^
    Back in the day I ordered a '01 7.3L Super Duty 6-speed. You got hard gears vs clutch packs.
    It's tow capacity was lower than the automatic, even back then -

    The added weight of the diesel engine and cooler is also a reason why the diesel will have a lower tow rating, it's going to be heavier and will eat into available GVWR/GCWR. It has nothing to do with the capability of the diesel motor. Essentially, those waiting for the diesel either plan to tow a lot, and are counting on better fuel mileage, or have other plans in mind for the added power.

    Here's the thing though you could pull a trailer up a steep road far easier in Diesel at lower overall engine wear. LOWER RPM

    What with this, what is realistic to think that I can tow my JK on 40s to the mountains? This is very concerning and the only reason I was going to go with the diesel.

    I’m definitely not sure if the 3.0 will do it down...a 20’ flatbed and a 6k lbs Jeep...I’m getting very sad

    Do you have a aluminium trailer? If not, you might want to look into one to keep the total weight down. Thats what im going to end up doing to tow my jeep srt8 to the track.
