2020 Diesel JL Wrangler officially announced, with 260hp / 442lb-ft and new 8 speed

[TXJeepScientist]

80% different engine than that in the JLU. If you learn nothing else from VW and FCA, know that if they offer to “fix” your vehicle to appease the EPA and pay you to do it, run. Don’t even think about it. I doubt you’ll see any similar situation with the gen3 because FCA will be out multiple billions when the dust settles on this last emissions fiasco and you can bet your last dollar they won’t be playing in any shades of gray with the emissions software on the gen3. Will the gen3 be reliable otherwise? Time will tell but your odds will be a lot higher if you live in a place where you can delete the DPF, EGR and DEF systems.

I think we have to wait for more info from FCA about the engine.

I know the tow rating won't go up, but what about the payload?

I wouldn’t be surprised if payload went down due to the diesel’s extra weight

Concur... The diesel is an easy 200lbs more than the 3.6... plus all the BGS and DEF gismo's..
JL's are heavy enough...

You said the diesel Jeep needs to have the DPF, EGR and DEF deleted. And I said deleting them is a huge gamble that will likely be a losing proposition for those who do it.

Losing in terms of:
* Warranty
* Smog/inspection
* Reliability

There may be a few who will pull one or more but it's unlikely that anything good will come from it given the 3 issues I've listed

Most folks wait until the warranty is up anyway before taking those parts off. So long as your post-delete tune does not throw a CEL, most folks who live in states requiring inspections would still not be caught with the DEF/DPF/EGR deleted because most aren’t actually checking pipe emissions. Reliability without those parts is absolutely better...that comes from experience and reports from nearly every modern diesel manufacturer, as they all have issues with those three systems.

The tq numbers are great on paper, but until they increase the towing capacity, it’s really not a huge deal to me. Will the extra tq help it pull 3.5k better? Sure, but it’s not all that bad with the current turbo engine. If we could actually get some real towing capacity, that extra tq would really help out.

If you need to tow more than 5500 lbs, a wrangler is the wrong choice. It’ll safely pull that weight though and the diesel will see the least mpg loss under load. If you plan on towing under 5500 regularly and your region does not tax diesel to the point of long-term significant financial loss, it’ll be your best option assuming you can afford the $4-6k premium up front.

Glad to see it’s coming out finally! I got impatient and bought a Raptor. Definitely not the off road capability of a Rubicon but still very fun and more enjoyable on road for not much more than a Diesel Rubicon will cost.

I will wait and see how the aftermarket support is for waking up the diesel and maybe trade in a few years from now.

So is the diesel rated higher (5.5k) than the current 3.5k?
The only thing I tow is my race trailer and 99% of the time, it’s towed with a dp motorhome, so the tow vehicle isn’t an issue. It’s that 1% where I might need to run it somewhere in town and the motorhome either isn’t practical, or isn’t even possible due to where I’ve got to go.
It would be great to be able to tow it with the Jeep for a few miles (10-20) if needed, instead of having to borrow a truck, but with a 3.5k/350 rating, there’s no way I’d feel safe doing it. If it were rated for 5.5k/550, I’d still be a little over, but close enough to where I didn’t feel unsafe going across town. (Of course, AFTER installing a brake controller in the Jeep as well.)

BUT.... On highway or other non stress scenarios.. A manual has my heart too...

I know.. buy both

Sounds like you need a ZF WSK 400. https://www.quora.com/Are-torque-converters-ever-used-in-manual-transmissions-If-not-why

JLU is rated for 5500 lbs in countries with 100km/hr towing speed limits and trailer brake laws. Diesel won’t be significantly different. You’ll be fine.

We all knew it was coming, but nice to see it in an official press release. New transmission to handle additional torque output, and the rumored 442 ft/lb of torque. Coming by end of year.

Well look at that! Only think I don't understand is why the ESS seems to be an added feature/option. Our ESS quit working in our 2019 Rubicon and we couldn't be more elated!

Why does nobody think the tow rating will go up when torque goes up 50% (and is available at lower rpms)? I'd lay money ($1) that it ends up even higher than the export market JLUs mentioned earlier in the thread.

Because the rating is not limited by this particular vehicle’s ability to pull the weight but rather it is limited by the ability to slow it down from 85mph and stabilize it at the same. None of the chassis, suspension, or braking components involved in said functions will be different. In fact, the curb weight will be higher so the ability to brake from 85mph will be even less, so slowing the same total load would require a lower tow rating.

Because the engine has not been the limiting factor in Wrangler’s low tow rating.

The 3.6 has tow ratings of 6,200 lbs in the WK2/WD and 7,000+ in the JT.

Good answers. I should have known since I poo-poo others' reasons for the low tow rating.
