2014 Grand Cherokee - MPG? Let the speculations begin!

Here is an interesting article (from 8/24) about 2013 Dodge Ram's MPG:

http://www.allpar.com/news/index.php...inivan-mileage

Apparently MPG (for V6) went from 14/20 to 18/25 which I think is fantastic. Seems like very similar technology was added that we will see in 2014 GC.

Obviously makes you wonder how much of an mpg bump 2014 will get for V6/V8 models. Diesel's mpg will be interesting as well.

Re: 2014 MPG - let the speculations begin

the current V6's get better than that already.....on a recent short trip of 400 miles i got 22 in my wifes V6 Durango and that included a lot of city driving etc. I think on an all interstate, steady trip at 75 mph I could get 25-26 easy. 70 mph...probbaly a few better

It looks like that's for the old 3.7L Magnum V6 w/4-Speed Automatic Trans though.

Re: 2014 MPG - let the speculations begin

According to this: http://www.fueleconomy.gov/feg/Power...00&srchtyp=ymm

The 2012 Chrysler 300 w/ 5 speed gets 18/27 for 21 combined, and w/ the 8 speed it gets 19/31 for 23 combined.

Re: 2014 MPG - let the speculations begin

The ram gets 25 hwy in 2 wheel drive according to this article http://i.autoblog.com/2012/08/24/201...-review-video/

I'm guessing 18/25 for the 4x4 jeep.

Re: 2014 MPG - let the speculations begin

A lot depends on the gearing and whether they modify the cams to be peakier (do not need as broad a torque range with an 8 speed). Looks like they are also smoothing the aerodynamics a bit.

That said, the EPA cycles are not steady state, there is quite a bit of acceleration: being able to meet the cycle without ever going into power enrichment is a key to a good rating. Also keep in mind that the cycle never exceeds 60 mph.

They totally changed engines. I'd expect 1 or 2 mpg extra at most from the new transmission.

As mentioned previously, the EPA testing is fairly inaccurate to actual driving. Certain other American car makers *cough* GM *cough* have exploited this on some of their newer vehicles, with models that have hugely amazing EPA ratings, but real life numbers fall far short of that.

EDIT: I think the logical thing to do is look at the most similar competition to the GC - the ML. With its 7 speed transmission (let's call this a wash with the 8 speed, because it's likely MB will have this transmission optimized better than the 8 speed will be by Jeep), more advanced engines than Jeep has (turbo V8s), and a gearing set more for economy than offroad prowess less weight, and a less rugged and more efficient awd system, the ML350 does 17/22 while the ML550 does 15/20. The VW Touareg with an 8 speed transmission is rated at 16/23 (admittedly, it's V6 is a bit outdated, but is still a great powerplant) despite being lighter and less offroadable than the Jeep.

I really don't see this transmission improving on the fuel economy that much, considering that the Jeeps already have stellar fuel economy compared to their rivals. The Touareg only gained 3 mpg when it went from the 6 speed to the 8 speed, and it also got a host of other changes including making it much lighter, making its 4x4 less rugged and more efficient, etc.

Again, I'd expect a 1-2 mpg difference in fuel economy with the 8 speed, based on empirical data.

Re: 2014 MPG - let the speculations begin

I will try to find the source/article, but I saw something that said Jeep was expecting about a 12% increase in gas mileage for the V6 between MY12 (5-spd) and MY14 (8-spd).

Re: 2014 MPG - let the speculations begin

Would wager any extra MPG on the EPA cycle would come from less power required on the accelleration stages and not steady state. Can't profitably drop the revs any lower than the current fifth below 60 mph.

I do think they could run the engine a bit cooler since they are using the variable oil pump.

Back in the day I recall one mfr getting in trouble for using lightweight synthetic breakin oil for the tests.

I would guess that's pretty much standard fare now.

Re: 2014 MPG - let the speculations begin

"blem wit" was that the owner's manual said "use dino".

My bet: 3.6 in '14 WK2 302hp: 4x2 18 city/25 highway & 4x4 17/25
