Re: 2014 MPG - let the speculations begin

I speculate the CRD with 8 speed auto will get somewhere around 40mpg and be the first ever full size SUV to do so...








...bwwaahahahahaha I WISH!! I'm in the market for a Wrangler and wish they'd release info about that coming in CRD.

Re: 2014 MPG - let the speculations begin

My prediction is 18/25 (wouldn't be suprised if I see 26) for V6. As far as CRD is concerned I think it might go as high as 30MPG highway.

Re: 2014 MPG - let the speculations begin

40 mpg would be either Imperial gallons or the Smokey Yunick Edition 3/4 size replica with the 2.0 CRD.

Re: 2014 MPG - let the speculations begin

I'm still waiting for the other shoe to drop. 18/25 mpg is great, however if the ram is running like a dog with the 3.6L, then whats the point.

Damn you Chrysler, just kill the 4.7L V8 already, its completely useless now. That engine should have been dead a few years ago.

Re: 2014 MPG - let the speculations begin

Those figures are for 4x2 from allpar.com. This looks pretty damn impressive ...

Ram 1500 4X2 Pickup Estimated Fuel Economy (city/highway)Engine / Transmission Liters/100km Imperial MPG U.S. gallon MPG
3.6L Pentastar V6 with 8‐speed auto 11.4/7.8 25/36 21/30
4.7L V8 with 6‐speed auto 15.0/10.2 19/28 16/23
5.7L HEMI V8 with 6‐speed auto 15.4/10.2 18/28 15/23

Re: 2014 MPG - let the speculations begin

Guess should be 20/29mpg City/highway, latter probbly a little worse.

...its the data of the touareg using the 8spd with a comparable crd engine.

Happy Day

Re: 2014 MPG - let the speculations begin

Earlier this year I did some fairly exhaustive poking around to come up with a good estimate. I posted my comparisons on another website that shall remain unnamed. http://www.jeepforum.com/forum/f309/...l#post12893021

My conclusion at the time was:
Quote:
My subjective and conservative guess based on a general review of the stats below is that it would be reasonable to think the diesel Jeep GC could get 20 city and 26 highway. Those numbers would be fantastic because there is no other off-road worthy vehicle that comes remotely close!!
I later amended it based on some other evidence to possibly get highway economy as high as 27 or 28MPG. If we get that good, I think it will be a fabulous success. It is highly unlikely that the city economy is any better than 20 MPG.

Re: 2014 MPG - let the speculations begin

It should lie somewhere in between the Ram 1500, which in HFE config. it is 18/25 and where the LX cars is, 19/31. My guesses:

V6/8 speed combo
4x2 - 18/27-28.
4x4 - 18/26

Hemi/8 speed combo
4x2 - 17/25
4x4 - 17/23-24

This is based purely on changing the transmission/engine combo. They may add others features such as stop & go, active grill shutters, electric steering, recalibrated air suspension, reduce in weight and many others things to increase efficiency even further.

Re: 2014 MPG - let the speculations begin

You may be right about real road cruise but do not forget that the EPA highway rating never exceeds 60 mph and does a lot of accelerating/braking with very little cruising.

Any real improvement will come from more gears needing less PE to accellerate but to affect the 55-70 cruise MPG is going to need new cams & maps with even lower/shorter peak torque: 1400-1800 rpm.

If there is a real benefit, it will be to the diesel and not so much the Pentastar. YMMV.

Re: 2014 MPG - let the speculations begin

I don't see highway fuel economy going up by that much. The overdrive in final gears on my Hemi is still pretty high, so when you factor in the ACM, the reality is, you need a certain amount of hp to move a 5200+ pound vehicle at 60-70mph. No amount of extra gears will change this, and this is what will affect your highway fuel economy.

I can't speak as much to the V6, as my experience with it is much shorter than my V8, however I recall it spinning at lower rpms more often than not as well. I wouldn't expect a huge mpg increase, you're still talking about a 5000 pound vehicle.

Truth be told, my biggest limitation on fuel economy right now is these damn hills and mountains. When I was on the flat lands down in Florida, I was getting 24mpg highway, cruising at 75. The hills significantly increase the amount of power needed to drag this heavy beast up an incline.

Another interesting point though, all 3 engines are going to be using the same transmissions? The same gear ratios will not work for all 3 engines. So those gear ratios will have to be picked around either making all of them "good enough" or making one of them great. It wll be interesting to see.
