A report that came after this said the update was pushed back to 2018. There are probably 50 threads about the pending diesel. We'll see soon, I guess!

The Edmunds "report" is way over a year old, no less.

First of all the wrangler won't get Near the fuel eco. Of the grand Cherokee, more like 24/20 I would say "its still a box on wheels" with diesel fuel costing the same as premium, cost of the engine, and giving up 45 hp ! not worth it.

Turbo Diesel would be better.

Most people want the diesel for the low end torque not the better MPG.

In the real world, these engines are getting about 6-7 MPGs more than gas engines in the same Jeep. So as long as diesel fuel is less than about $0.80/gallon more you're still saving money with diesel.

Not to mention that the diesel would have 150 lb/ft. more torque than the Pentastar (!) and that's not an exaggeration. It would totally and completely change the Jeep driving experience for the better. I've owned two Jeeps with diesels and I can confirm this.

Yes but those jeeps are a lot for aerodynamic than A wrangler "you can't compare apples to oranges" , and more torque sounds great, but this is a turbo diesel. So where is that torque coming in at? Ive owned several turbos , and the power kicks in at the higher rpms.

With a diesel you can pretty much idle over most obstacles. The 2.8L diesel produces about 340 lb-ft of torque at 1,600 to 2,600 rpm.

My bet is that it will be similar to the one released in the UK

Not sure what you mean "higher RPM's"....the peak torque of the diesel is 1600-2200 RPM's.....turbo or non turbo. Turbo just means more power in those RPM ranges.

I would love a diesel option. But it would not save money unless diesel fuel prices came down below regular gas prices. I have a hard time justifying the added initial price and the added maintence cost of the diesel if it does not pay for itsself in fuel economy.

Mine made 370 lb/ft at 1,600 RPM. The Pentastar gas V6 makes what, 180 lb/ft at that point? Again.. turbo diesel in a Jeep is a complete night/day experience. You have to own one for a week and you'll never want to go back. If I could have that I-4 turbo diesel in a JKU I'd be set for life.

The Diesel if equipped with the correct gears and transmission will be a great option . One that I would want for the hilly area here . That torque pays off in spades when pulling hills.I can also see aftermarket turbos and tunes making massive power.

An I-4 diesel is what I would hope for too. It wouldn't be as smooth as the V6, but it would give more room in the engine compartment for batteries, compressor, welder, sPod, etc.
Once the engine bay is loaded up with all of that, servicing is pretty tough.

I am specifically hoping for more low end power, and more room in the engine bay. Anything beyond that is just icing on the cake.

Why the hell would you want that?..The JK is the nicest style inside and out of any Wrangler yet IMO...well maybe the Cj's were at the same level in a rough around the corners sort of way, but unfortunately the governments wouldn't allow such a simplistic vehicle to be made today.

It all depends on tune and turbo size. Usually larger turbos result in a longer turbo lag. You can have near max boost and torque at 2000 rpm with a gas engine.
Now turbo diesels are another story. You'll have the majority of your torque available under 2000rpm. Think about the big turbo diesel trucks, their redline is at 4-5k rpm.

Also, this article was published over a year ago...

Hi

Read what people think about diesel. I dont think americans would be satisfied with the european diesel. You will probably get a bigger one. The current is like to drive a slow tractor compared to a Pentastar

Keep going. Back to '83!

So have we given up hope that the Diesel will arrive this summer in the 2015s?

And take off all of the EPA $&@*%# and you would probably get mid 40's to 50. Just traded my last diesel for my JKUR. Will not buy another till the gov't gets out of the way. You better have a budget of about triple your gas vehicle just for maintenance!

I'll put it into perspective for you.. The Jeep Liberty CRD that was sold in the U.S. had a 2.8L I-4 turbo-diesel and it was backed by the 545RFE transmission...the same transmission used in the Ram 2500/3500 with the Hemi V8. And the little Jeep CRD made so much torque that the transmission torque converter couldn't hold it and had problems slipping even in brand new Jeeps.

They ended up after several years finally issuing a TSB for dealers to install an upgraded torque converter with much larger springs to hold the torque of the diesel...and that was in stock form! With the tune from Green Diesel Engineering you could add 70 lb/ft of torque for a few hundred bucks. It was amazing.

I can't believe they still haven't sold Wrangler CRDs here. They would literally sell out before they were unloaded from the trucks.

Big myth is Diesel MX is expensive, learn todo a few things on your own. The fuel savings would counteract the cost of the Diesel engine in about a 1 1/2 years.

Don't know where you get your #'s...but you better recalculate. When a diesel upgrade itself is 4-7k, you can buy a lot of gas for that. Go buy fuel filters and oil filters and air filters...about 3-5x more expensive. Don't get me wrong, I love diesel. But don't believe your going to save money in the short run. You buy a diesel today for torq or longevity, or both, NOT to save money in the short. Good luck!

Side note: been running diesel for almost 20yrs. Today's diesel is not like grandpa's old truck or tractor.

My Jeep CRDs held 6.5 qts. of oil, so same cost as a gas Jeep. Oil filter was $6.50 for a premium Purolator, so same cost as gas Jeep. Air filter was $15 bucks so same cost as gas. Yes I did have to buy a fuel filter every 30K...but I did not have to ever buy spark plugs so it's a wash.

There is NO additional cost of maintenance for a diesel.

And the engine option itself was $1,800, not anywhere near $4K

Where you do get into more cost is after the warranty period if you need parts. The parts do cost a little more simply because they don't sell as many of them here in the States.

Guess I'm accustomed to big Diesel engines and they are a lot more expensive to maintain. Oil filter 18-25/ depends on how many you purchase. Fuel filter 39-45. Oil= 12qts. And you should change fuel filter sooner than 30k if you use your diesel. And air filters 40-50 vs 15-20. Guess big is more expensive too!!! If only $1800 upgrade...they will be hotter than a crack rock in Atlanta!

I have had a couple of the small diesels Audi TDI. Run great get about 48 mpg. I think the other benefits of torque, mileage and MX make the diesel a more sound engine. Someone should join a UK forum and see what they think of the diesel in comparison,,,, I bet they like it!

I've owned a 2012 BMW X5 3.0L diesel for a couple of years. My mileage is about 35% better than my prior car - a similar Audi Q7 with a 3.6L gas engine. I now get 18 to 19 mpg vs. 14 to 15 mpg with the Audi. (Almost all my driving is short trips in the city. If you do a lot of long distance driving, you may have different results.) With the cost of diesel in the US so high - especially compared to regular gas, I see no cost savings in owning a diesel from the standpoint of fuel costs. The fuel savings benefit is offset by the higher fuel cost.

Most modern diesel vehicles list for $4,000 to $5,000 more than a similar gas engined model. I only bought my diesel because BMW ran a $4,500 discount which offset the $4,500 premium price for the diesel at the time. So I paid the same as I would have if I bought the gas engined model.

There is a financial benefit to diesel in that the resale price is higher than gas. When I check my vehicle's trade-in value, the diesel is worth $4,000 to $5,000 than an equivalent gas vehicle. So had I paid the premium price, it looks like I would get the money back in the end. I figure the diesel commands a higher resale price because of its lower long term maintenance costs.

The real reason I like the diesel better than the gas cars I've owned, is that the diesel has so much more power and torque. It really is phenomenal.
