Diesel Jeep Grand Cherokee Coming Next Year


Chrysler announced that not only was it hiring a third shift of workers to build more of its popularly redesigned Jeep Grand Cherokee in Detroit, but that it would also add a diesel version of the SUV to the lineup sometime next year.

There weren’t more details about the vehicle itself in terms of specs or mileage, but the company also confirmed the next SRT Viper sports car — not called a Dodge — will go on sale this year as a 2013 model.


WHY???? Anyone seen the price of diesel fuel for the last year?


Some people little the longevita of a diseal. Although it is not really needed since most gasolina engines last pretty long. It come down too how impression is the milleage for the diseal engine. I am sure FIAT-Chysler should be able to build it economically due to European options.


It's already available in EU, 3.0 V6 diesel


The diesel would have way more power at low engine speeds that the torque-lite 3.6 V6.
Couple that with the ZF 8 speed automatic and you have the best mileage, and real world performance as good as the 5.7 V8.


But it's only 177hp vs. almost 300 from 3.6 gasoline engine. Acceleration would suffer


The Euro Diesel Jeep has 405 lb/ft of torque. It will accelerate 0-60 in about 8.2 vs. the hemi powered v8 in 7.5. The diesel will also get about 50% better fuel economy.


Wrong. The gas v8 has cylinder deactivation and can match the diesel mileage when it's in 4cylinder mode.


If you've ever driven a diesel you'd know why.. You get the performance of of a big V8, with the fuel economy of a 4cyl.

It's not about the HP, its about low end torque- and diesel engines have it all over gasoline. Look at any tractor trailer or bus-vehicles that make money by moving- and they are all diesel.

Diesel got a bad rap in the US for cars during the 70's and 80's- mostly because US car makers put out really bad engines. But again, go anywhere else in the world - especially places where gasoline is north of $5 a gallon- and they all drive diesels.

Seriously, go test drive a Golf TDI and compare it to the gasoline car, its a totally different beast.

I think a Jeep GC diesel is a really good thing; I would consider it for purchase.


A 3.0 diesel turbocharged V6 will have more than 177hp. A minimum of 240hp & 400ft-lbs is realistic.
The Hemi, even while operating in 4 cylinder mode does not match the BSFC of a modern diesel engine.
In real world driving, a diesel rarely exceeds 3000 rpm. 3000-4500rpm is rarified, but a diesel makes about 90% of maximum power at 3000rpm.


Jeeps record with diesel power says your wrong. Remember the diesel jeep liberty?? Owners complained about the lousy mileage and jeep pulled it from the market. Theres no way a diesel v6 can match the combination of power and economy of the chrysler hemi that can operate as a 4 cylinder gas engine. Don't respond without actual numbers. Diesel for non commercial vehicles is pretty much a bust. That's why Bmw dropped its diesel 3 series for 2012. Thats why jeep dropped the earlier diesel suv it built.


A 240hp 400ft-lbs turbo-diesel V6 coupled to the ZF 8hp70 transmission will provide as good real world performance, while returning better mileage than the 5.7 V8, even taking into consideration the non-upgrade '6' speed automatic version of the 545rfe (in the real world 99% of the time you are not going to benefit from shifting from the old 2nd' 1.667 to 2nd 1.5. It was a marketing move to try and fool people into thinking they are not that far behind as they really are.)
The 5.7 hemi doesn't have VVT it has VCT; valve overlap is fixed.
The 5.7 would have more power than this diesel V6 from 3500rpm and up, but the tall gearing means the 5.7 has to spin up there to make up for transmission deficiency. (it just upshifts out of 2nd gear before the end of the 1/4 mile)

The previous diesel engine offerings weren't really that bad, it was the transmissions they were hamstrung with that was the problem.


I hope you're right, but you hit the nail on the head when you mentioned real world performance - you say the transmission can make up for the low revving diesel. I think the higher revving gas motor with cylinder deactivation will prevail in the real world.


George (Diesel) 1, stanford (gas) 0

Diesel stinks

reasons not to buy the diesel jeep next year:1) expensive emissions additive ($20 per gallon), 2) diesel fuel costs 20 percent more than gasoline where I live, 3) few service stations have diesel fuel, 4) waiting 10 minutes behind a stinking big rig to fill up at the truck stop, 5) diesel is slower than hemi, 6) if you use the turbo power on the diesel at all you will see mileage in the teens, 7) diesel grand cherokee will be more expensive, 8) Jeep cancelled the diesel Jeep Liberty and will probably do the same to diesel grand cherokee.

L.M.C. & Co.

I have the VW Toureg and it is AWESOME it has a 3.0 V6 with 225hp and 405 foot pound torque it really moves, I beats our old GMC acadia with a 3.6 V6, and gets better gas miliage. I can wait to see the JEEP. (We are a Tier one supplier to Chrysler and Their quality is very good, the are very carefull)


Prior to buying my 09 Grand with the 5.7, I took a test drive in a model with the 3.0L MB Diesel. It took me MONTHS to find one at a dealership - Chrysler just wasn't producing them, even through every dealer I talked to said they were constantly getting inquiries. I have to agree with George on this one - the engine was great, the problem was the 5-speed auto transmission it was mated to that just wasn't well suited to keeping the engine in it's power band. Even with it's problems, I nearly chose that platform over the Hemi. However, put the same or a similar engine in front of the new ZF 8-speed, and your problems are largely solved - I'll be the first guy trading in my Hemi when they show up at the dealership in that configuration.

As for complaints about Diesel fuel being more expensive, a little simple math will prove that to be a non-issue. On average, Diesel-equipped vehicles are 30-35% more fuel efficient than an equivalent gasoline model. So even if Diesel if 15% more expensive per gallon, you are still saving 15-20% due to the improved efficiency.

My daily driver these days is a VW Jetta TDI. I see 33MPG in town and over 40MPG on the highway, and my car is every bit as zippy as the gasser models are. It's a great car. If Chrysler can match what VW has done with their Diesels, I think they should see a lot of success.


Stanford, you are wrong. I own a 2008 Grand Cherokee with the 3.0L CRD. It destroys the HEMI when it comes to gas mileage. No contest. Period. I drive it like i stole it and constantly get 21mpg combined. If I play nice it gets 24 mpg. This is real world mileage and is consistently repeatable.


A little research shows that those screaming about how bad a diesel will be, can easily be proven incorrect.

The V8 comes in at:
MPG (City) 13
MPG (Hwy) 19
MPG (Combined) 15

The CURRENT 5 speed Euro spec Diesel comes in at:
MPG (City) 22.8
MPG (Hwy) 32.7
MPG (Combined) 28

Even assuming fuel prices as the following:
Petrol: $3.80
Diesel: $4.36

Estimated annual fuel costs are:
Petrol: $5,066.67
Diesel: $3,114.29

Add in that the Diesel can out tow the V8, and is less then a second faster in the 0-60 catagory, it's kind of a win/win to go diesel.

Yeah, the engine will add a grand or three, but it will also pay for itself very rapidly.

As for other automakers pulling cars? BMW is rolling out a 5 Series in diesel in the US. GM is also rolling out the Cruze in diesel. Most automakers are actually bringing more diesels to the US now. Diesel has been powering Europe now for some time (60%+ of the EU fleet is Diesel).

Happily Awaiting It In The US

I'm thrilled it's making a comeback in the US as a 50 state legal diesel. That previous 45 state diesel was a bad idea. I sold Jeeps in California at the time and it was a pain to find used ones with low mileage but more than 7500 so we could resell them legally as used. Couldn't keep the few we ever got for longer than a week.

The mileage on the current GC with the diesel is about 26-28 mpg real world. There are people seeing just north of 750 miles per tank. You would be hard pressed in a gas GC to stay over 22 mpg average. In my area diesel is either 5 dents less or 3 cents more than premium fuel, so ever at the diesel being a 3-5k premium it'll have paid for itself in a little under 2 years.

Not to mention all that torque while sacrificing about 3/4s of a second to the Hemi in 0-60


Happily, I read your comment with interest because I bought my wife a 2012 JGC Overland Summit V6 4X4 last November.

I think that the diesel is a nice option but I would not be interested in one since the Pentastar V6 is more that adequate for what we use the JGC for.

A lady friend bought a 2012 JGC Limited 4X4 with the 5.7 and the 5.7 has changed the whole dynamic of the JGC making it feel and handle differently from the V6 version.

I prefer the nimble handling of the V6 version.

And while the SRT8 is an option for those who want a potent brute, there aren't too many people who will want to dish out the $64K for a daily driver with lousy gas mileage.

I'm sure that a Diesel JGC will sell to a few people, every car does sell to a few. But I think that most people will prefer either the V6 or the 5.7.

Given the weight of the JGC in any trim, no one should buy a JGC if they need to worry about the price of fuel.

I think the Diesel JGC will be a novelty offering that appeals to a relatively few buyers.

The best engine and transmission option in the JGC may be the V6/8-speed auto, while the 5.7/6-speed auto would offer the best all-around towing utility version of the JGC.

A Diesel JGC will not sell in sufficient numbers to break even.

Out of interest Australia is a strong Grand Cherokee market with similar needs and culture to the USA. Here the diesel is smashing the petrol sales with vastly better resale, economy and consumer feedback particularly if you tow. I have a 1 year old diesel CRD and it amongst the best cars I have ever had with now four of my friends having purchased one or awaiting their arrival....They are sold out in some models for up to 6 months!


ed; It wasnt all the US automakers that put out bad diesels engines in the 70sand 80s It was only GM that made a converted 350gas engine into a diesel engine and put it into anything they sold as a diesel engine. GM always made junk and sold it in all of there brands and people would blame US automakers for putting out junk. The records show after people got finished with GM junk they would go buy a Jap car blaming it on all US cars makers. If you got 100,000 miles out of a GM engine in the 70s and 80s you had a good GM engine. It tood GM 7 brands to be number one, it took Ford only 2brands to be just under GM in sales.


The MV diesel to be used in the new JGC has been around for many years in Europe and is used in several other vehicles.

It has great torque to weight ratio like most diesels do, but I just can't see a great demand for it in the USA.

Most people in America don't care about mpg or the price of gasoline. They just buy it and worry about running short of money later.

So if people don't care about the price of gas or mpg, why would they want to pay the premium for the diesel engine?

I'm sure they'll sell a few in America, but I think it will always be a novelty in America.

Too many people had too many bad experiences with earlier diesels from ALL manufacturers. Yes, even those from the venerable Mercedes-Benz 200D, 220D and 240D.

Given the choice, most Americans will choose the Pentastar 3.6 over the diesel.

But a supercharged or bi-turbo Pentastar would be something I would definitely buy!


Our company had a Mercedes 240D. In the winter time they had to leave it running 24 hours a day because on a cold morning it wouldn't start. Not much fuel savings there.


Those were old diesel with injection in a pre detonation chamber. Old technology that is disappeared a good 10 years ago. I drive often in europe. In canada i have a 2011 5,7 hemi JGC. And i can't do better than 20 l / 100km. On the higway , with the 4 cyl. mode i manage to do 12/13 l x 100 km at 120 km/h speed.
When I'm in europe i usually drive a mercedes ML 320 CDI. Same frame, same suspensions and very similar engine of the 3.0 L by VM.
First of all the usual speed i drive there is much higher, 150-160 km/h on the higway and stip alpine roads.. And i still manage to do about 10 l x100 km. so about double the mileage for $. And accelleration, top speed, noise and comfort are not lower.
Moreover, last winter i was on the alps. It was a very cold night. I left the ML outside at -18C .the morning after no problem. Just remember to give the time to the heaing coils to act. Is better to repeat twice, just in case. The only downside is that the car takes more time to warm up, because the engine is far more efficient, so, it means also that has less heat to dissipate.
