2005 GC Limited with Hemi...
10.5 mpg in town and 16 hwy with cruise at 70 on flat grade. MDS doesn't really exist, engine surges, flat acceleration unless geared down. Junk.

I am curious about your post.
 
I just completed a 1,450 mile trip from Mississippi to Grand Lake, Colorado with a total elevation gain of 8,200 feet, traveling on mountain roads from Raton, New Mexico to Grand Lake, Co. I cruised at 76 mph on Interstate. My verified average mpg was 18.9. On Interstate stretches it average 20.3. I wonder about why your mileage is lower.
 
If you are concerned about gas mileage, why would have purchased a 5.7 Hemi Grand Cherokee in the first place?

I'm not convinced if an 05 GC Hemi has MDS, earlier truck/suv hemis' did not have this feature listed on the specs. I remember driving a new hemi durango when my 05 Jp Lib Ltd CRD was in the shop and the sticker said nothing about it as compared to my auto hemi, I could be wrong! Anyone know 4 sure?

I also have a 05 JGC 4x4 Limited with Hemi, and my numbers are pretty much the same as sonnet's below. I live in L.A. where the traffic sucks. My combined average driving is around 12 MPG.

The 2005 Jeep Grand Cherokee 5.7 Hemi should have MDS, you can check it by VIN number, also see at what speed MDS is active for your car.

I leased a '07 grand Cherokee 3 months ago. The mileage on the sticker stated 17/21. I am getting 10mpg in local suburban driving. (with A/C) When I complained to my dealer I was told that this is what this vehicle gets. When I spoke with Chrysler/Jeep, Jeff in Customer service had the audacity to tell me that you start getting the best mileage after you reach 20 and up to 30 thousand miles. Misrepresentation by Chrysler and the dealer. Don't get this vehicle unless you have a lot of money for gas.

V6 MPG & Towing capabilities by naatz1
Aug 23, 2007 (5:33 pm)

I have a 2001 JGC 4.0L I6 4WD with 82000 miles. It's generally been a good vehicle and my college Jr son plans to "buy it out" from me at a very good price to have a good vehicle driving to college in MN winters plus more metal around him in the summer than the sporty car he has now. I typically get 15mph in city (2WD mode) and 20 highway, ie, 19 75mph but 22 60mph on 2 lane highways.
 
I am looking at CUVs like the Saturn Outlook, Hyundai Veracruz, Toyota 08 Highlander. The 3rd seat would get occasional use and I want to pull a smaller 17ft 2500 lb fishing boat. However on other forums some have coached me to reconsider a Jeep true 4WD vehicle for towing and pulls out of the water, despite losing the 3rd seat. I can get a Chrysler product at employee price and the new lifetime warranty has appeal as I usually drive 'em into the ground.
But I -totally- resist buying anything other than a V6 in a vehicle I plan to have for perhaps 10years, I foresee gas at $4-5/gal in that timeperiod. Since the new V6 is (more refined?) than my old tried and true I6, can I get feedback from some V6 owners on both MPG and towing. Obviously I know the 4.7 would be a better tow vehicle but I just don't want that penalty for the <2% of the time I use it to tow a smaller boat & trailer. I am not real encouraged by earlier comments on this forum, but it's hard to believe a new modern V6 would get worse mileage than my I6 with a design point back in the 70s rated at 16/21.

Took my 05 GCL Hemi with 20k miles on a recent trip to LA, returning I got 20 mpg from Oxnard to Palm Springs driving about 70--the speed limit--and up and down the hills, etc. Today, I drove from Phoenix to Sierra Vista, around Fort Huachuca and returned via the wine country in Sonoita keeping the Interstate speed at 70 and around 60 on the mountainous state routes--20 MPG. There may be some things that Jeep could have done better, but it's not the Hemi's gas mileage. OBTW, there is nothing that can beat it off highway in the desert canyons--nothing!
