2014 Hemi EPA MPG

On the original posts about the new 2014s on this site, the Hemi 4x4 MPG was listed as 14/21. However on multiple dealer websites it says 15/23. Since the info is not on the EPA site, could someone who actually took delivery of a vehicle post what the sticker says?

THanks

14 - 20 combined 16

You should be able to see the actual window sticker for any car a dealer has in stock.

...So it only went up by 1 mpg in the city? And none on the highway?

'11-13 is rated 13/20 for a V8 4x4...

Re: 2014 Hemi EPA MPG

I see what your talking about..

http://www.kolossochryslerjeepdodge....40b5b3777e.htm - 15/23

http://www.chrysler.com/hostd/window...RJFBT3EC141021 - 14/20

This is for the same vehicle. If the V8 got that, then I couldn't see why people wouldn't want it but I think it is truly 14/20

Re: 2014 Hemi EPA MPG

There's been some discussion of MPG on the 2014s already. I'm currently averaging 12.3 MPG with nearly 100% city driving. Still sub 300 miles, so not fully broke in yet. That's in DC area (so just above sea level), 34PSI in tires, driving primarily in sport mode.

Re: 2014 Hemi EPA MPG

Since the new transmission doesn't really improve the mileage with the Hemi, does it improve the performance (e.g., acceleration)?

Re: 2014 Hemi EPA MPG

We need to see the EPA "detail" spreadsheet (only has SRT at moment). There is some interesting rounding that goes on: could improve by just .1 mpg and get rounded to the next (like the '12-'13 V6 2wd highway needed only 1.1 mpg to jump from 23 to 25). Until we see the spreadsheet without the rounding thre is no way to tell.

That's what doesn't make sense to me. There was talk about the new transmission improving mileage. With the Hemi they switched to a more economical rear gear ratio, and we see little to no improvement in mpg. On the other hand, the rear will provide poorer low end performance than the one they used in the past.

Hopefully some magazine will get to the bottom of these decisions and let us know what's happening here.

Re: 2014 Hemi EPA MPG

Mileage improvement with the 8-speed is going to be more noticeable for non-highway driving because it provides for shift points that are more frequent and that keep the RPM down. At highway speeds, you're in overdrive with about the same ratio as with the older tranny. There, the benefit is more during acceleration to speed, but once you are cruising, the benefit is less. Of course, if you are able to merge gently, then you'll gain a little more efficiency there as opposed to "stomping on it" all the time. They may have made some other tweaks that help in highway driving.

That's funny, one of the things I like about my 2012 Hemi is that it doesn't downshift very often and rarely goes over 2,000 RPM, even with the five/six speed transmission.

Re: 2014 Hemi EPA MPG

PECo, I agree...mine works just great in that way, too, just because of the way I drive. Sounds like your experience is similar. I have a light foot...and tend to get good mileage unless I have my horse trailer in tow.
