Re: 2014 Grand Cherokee - MPG? Let the speculations begin!

Matt,

I'm looking at a Hemi, but I wonder about what you call the 'new' diesels.

Are they really new, or are they just new to the US market. I was under the impression that they have been pretty common in Europe for some time.

Re: 2014 Grand Cherokee - MPG? Let the speculations begin!

The Jeep CRD has been in use in Europe just not in the US. Everyone will have thier own opinion on the Diesel on the benefits/disadvantage and if it makes sense in their situation.

Trailpixie - if the CRD only got 28-29mpg hwy, how would Jeep get people to buy it if the 3.6L might be getting 25mpg hwy? Their has to be some benefit to the CRD because their will be atleast a $3k+ price difference.

Re: 2014 Grand Cherokee - MPG? Let the speculations begin!

I will believe 25 MPG on the V6 when I see it. Right now it is highway rated at 23MPG, I think. With that said, if it does hit 25MPG and the Diesel is below 30MPG, I think the big difference will be the power and performance. towing with the diesel will be practical for many people, and the Diesel will probably be a bit faster and more responsive on the highway (contrary to popular opinion about diesels). the V6 may win 0-20 MPH, but the diesel will win a race to 60 or a quarter mile.

I'm pretty enthusiastic about the diesel, now I just have to hope that I can get an off road diesel cherokee without paying for seat heaters in the back seat...Yeesh!

Re: 2014 Grand Cherokee - MPG? Let the speculations begin!

Right now it might be 23mpg but they figure a 10% increase so that would take it to 25mpg. If the CRD can't get 30 and all a person is worried about performance, then what would be wrong with going with the V8?

Everything is speculation at this point until we actually get some numbers. Hopefully Milous will be able to get some soon.

20 MPG highway is no longer acceptable. Also, I suspect real world highway (75 MPH) economy for the V8 is closer to 18 MPG. Finally, 13 MPG city is completely unacceptable to me. Add your optimistic 10% improvement to those numbers and you still only get 14.3 and 22 MPG...still not acceptable.

Diesel has near-V8 performance with much improved economy. To me it is no contest.

Re: 2014 Grand Cherokee - MPG? Let the speculations begin!

Not to fuel the fire (no pun intended), a couple of paragraphs from a USA Today article last month on the Ram 1500 and the V6/ V8 mileage "speculation" (that's bold and underlined).

This gives me some hope on some good numbers coming from gas engines. I'm still thinking about the diesel engine, but with a spread of $.80 a gallon, it'll take more than free car washes, ice cream, ....

-----------------
USA Today

To keep up, Chrysler Group updated its 2013 Ram, the marquee mechanical modification being an eight-speed automatic transmission. It's standard on V-6 models, and boosts highway mpg as high as 25 mpg. Chrysler loves to point out that the rating is better than the Ford F-150 EcoBoost V-6's 22 mpg and also tops the F-150 base V-6's 23 mpg

and (for possible Hemi buyers)

But not everybody wants a big Hemi. Maybe.
The eight-speed will become standard on some Hemis in January, optional on others. Chrysler hasn't set all the details yet. Fuel economy of the Hemi with eight-speed isn't yet confirmed, but Chrysler insists it also will outdo Ford's EcoBoost V-6.

Re: 2014 Grand Cherokee - MPG? Let the speculations begin!

Usually the fuel economy numbers quoted in press releases are for 2WD versions of pickups and SUVs. Subtract 1 or 2 MPG from that number for a 4WD version.

That's true.
And then if you put in a Wrangler, subtract 5 or 6 MPG's

That's what you get for selling an automobile that is shaped like a brick...a pretty darn cool brick, but a brick nonetheless.

Re: 2014 Grand Cherokee - MPG? Let the speculations begin!

We have had the CRD in Australia for some time now.
On a recent trip, while towing a 2.5Tonne caravan, my CRD averaged 20.4 MPG. When cruising without any towing, I get around 29MPG. It would not be hard to get it into the 30's with an 8 speed..

Re: 2014 Grand Cherokee - MPG? Let the speculations begin!

Since my 86 21ft RV can get 27-30 mpg on the highway from a TD, I'd expect a near thutty yar newer design to close on 30 easily.

That said only the Ram 1500 HFE (high fuel efficiency) gets 25 mpg highway with a 3.6 and 8 spd, others get 23.

My experience is that 23-24 mpg average including stops is typical on an Interstate running left lane speeds with the air going.

Re: 2014 Grand Cherokee - MPG? Let the speculations begin!

Another thing to keep in mind is that diesels are known for getting about 20% better real world hwy mpg than what the epa lists. At least when driven at 60 or so mph.
