There is a huge variance between the numbers. We got 18 to 22 with highway driving and as bad as 12.7 to 16 at most with city. I used to get 14 at most with my KJ but it went up to 16.3 after I swapped the muffler and got rid of some weight from the cargo area.

When you say sound, is that the engine's purr or the sound from the back-end/muffler? I have an '04 KJ and the engine was whisper quiet, in most cases I could not even hear it while idling, after getting a flowmaster Super 50, it sounds amazing, and that's with V6, 3.7L. I am pretty sure you sqeeze a bit more agressive sound from WK2's V6.
How does EVIC give 19-25? Or is it varying that much day to day?
Nobody mentioned if Hemi has the active cylinder management (found out it is called MDS, and WK2 Hemi has it).
Do you guys feel the MDS when it kicks in?

Yes, I read about this, does anyone ever really buy mid-grade anymore?I mean, which such a little difference between the two, is HEMI that sensitive?

Is this city/highway/mix? If mixed, what's the balance?
So we got with Hemi
22.1 with 500 miles so far
22 with highway 70s
14-15 around town/city/local
18-20 200mile trips
18.3 with 60-70% highway
19 with highway 60s
12-13 with 90% city
13mpg city, 16mpg city with K&N Filter
12.7 with 85-90% city
19 Mixed, 23+ Highway with V6
19.2 with city driving
I think, nobody would get a HEMI if they are so much concerned about the fuel consumption, but it is also important to get a real life performance and fuel consumption numbers. One might be OK with 15mpg if that's what's posted on the sticker, but if majority of drivers are getting 10-11 that would seriosly put a dent on someone's wallet if they can just afford 15mpg vehicle.
Like CrazyJ said, the results seem closer to published numbers, however anything over 20, even if it is highway, is really impressive and makes one wonder. Especially 22mpg on a Hemi.
I guess they hit that sweet spot with MDS activated, and most likely taking advantage of overdrive (New Cherokee has it, right?)
PS: If you guys want, the topic can be merged with WK2 Hemi vs V6 MPG Compilation (results inside)
Thanks again for all the reports.
