Jeep.co.uk lists their fuel consumption as 39.2 MPG "extra urban cycle". Divided by 1.2 to convert to US gallons, is 32.6.

Or if you use the 100km / 7.2L consumption rate, multiply by 62mi/100km and 3.78L/1 US gal = 32.55MPG.

I'll take 27, 30, 32, whatever it is it is better than I'm getting now in my JK. Not to mention the increased torque from the diesel.

I think I will either eventually put a diesel in myself if it takes to long to get them here in the States, or buy a new one when it comes out.

If you're looking to do the swap just for fuel economy, it doesn't make any sort of financial sense.

A Cummins 4BT in good shape or rebuilt is a few thousand, a Toyota or Volkswagen 4-cylinder is even more. Then you need a new transmission and a bunch of assorted swap parts...you're looking at $6,000 in parts alone for a good 4BT swap. And that's assuming you do all the work yourself...turnkey diesel swaps get well north of $10,000, enough to run a Wrangler on gasoline for basically its entire lifespan.

Plus, the 4BT is actually a terrible choice for a DD Jeep-unless your Jeep is built up heavy as hell, apparently it never puts enough strain on the engine to get it to warm up fully (That was the problem that a formerly-local 4BT-powered TJ owner had-it rocked faces off-road, but was barely more efficient than the original I6)

Yesterday, the World Health Organization named diesel fumes a carcinogen and linked it with lung cancer especially prevalent in over the road trucker (who coincidently are probably heavy smokers). That being said, I probably wouldn't be looking for any new diesel applications coming from the big three automakers any time soon. WHO confirms diesel fumes carcinogenic http://www.abc.net.au/news/2012-06-1...ogenic/4068414

Ok so we'll now put diesels with well done steaks, burnt toast, alcohol, thinners and all the other things that "may contribute to cancer" shall we? What next, coffee, cake and sex? Probably only when taken in that order.

Exactly how close would one need to be to the tailpipe and for how long in any one session or cumulative before one "may" inhale enough of these nasty carcinogens before one "may" get cancer?

With all due respect guys I think the majority of us will die of old age before we die from diesel fumes inhalation. They have been around for a while now, not exactly new technology. Having said that I'd hazard a guess that more have passed from petrol (gas as you blokes say) than we'll ever see from diesel fumes.

Everything gives you cancer these days. I'd say you'd probably get more harm from a house full of new carpet off-gassing than a new GC diesel.

Rant off.

I don't know about you, but it's October for me, not June.

And the WHO has no regulatory powers concerning the auto industry. The EPA already recognizes many car exhaust chemical as carcinogens.

Would a diesel improve the towing capacity of the Wrangler Unlimited?

Thanks,

A diesel and nothing else? No. Horsepower is not the problem, Pentastar-equipped Grand Cherokees will tow 5000 pounds, the Ram 1500 will tow 6200. The frame, brakes, steering, ect all need to be reworked to up the Wranglers towing capacity.

It won't improve the towing capacity but I don't think that's what you're actually meaning. If you mean ability to tow easily and not be changing gears every time you come to a grade then yes it will. It's all about the torque and diesels have that in spades. We used to drag a loaded trailer all over the place behind a 2008 2.8CRD JKU and you literally forget it's there. Can't wait to load up our new GC 3.0V6 and how that goes.

Diesel Wrangler

I really wish the American auto makers would quit screwing us over and put out diesels left and right. Europes been doing it for decades. I for one, would gladly pay the increase in overall cost and fuel prices for diesel. Three reasons- much better MPG's, diesel engines last forever, and typically you receive much better power output.

people still have bad taste for diesels here in the U.S. because of some terrible designs from manufactures. you also have the incorrect belief that diesels get poor gas milage and are unreliable. It all points to low possibility of them producing a lot of them to sell over here.

^ it made more sense in my head

Yeah it's a double edged sword though with reliability I reckon although that remains to be seen. We have loads of diesels over here, they are in everything even little Hyundai I30. The thing is diesels are no longer big solid blocks with a few pistons going up and down slowly. They are high revving, variable vein turbo, high performance engines and as everyone knows when you squeeze more power or torque out of the same sized holes there has to be a trade off. In our opinion that trade off will be that we won't see 3 or 4 or 800 thousand miles from our current HO diesels like we typically have from our old land cruisers and such.
For the time being though we are all loving the new crop of high performance oil burners from Europe. As soon as they offer the 3.0 V6 in the JK ill get back into one of those.

Lets revive this thread for discussion. I heard on the grapevine that Fiat is planning a test amount of Wranglers and GC's with diesels.
They wuld be using the Fiat 3.0, and the import would be in 2014. So lets see if any get this far,
and since I live in the socialist state of California, it probably would not make it here.
