Well i have had her for a 18months now and i must say i love the car. If i cruise at 73 and dont bother her i will get 21 to 23 and thats it. I have gotten as little as 15 had to get some where fast Washington to Pa in 3 hours. All in all 19 is about it on these cars.

 

I get 10 to 12.5 mpg 2007 AWD HEMI inferno red. I also must mention that I also snaped off the gas pedel the second week I had it...it had 1400 miles on it. The dealer said I brought a new meaning to lead foot. I also got in an accident at 1900 miles due to some slapass is a ford f 350 $13,000.00 in damages. Everything that got damaged was what would be changed to make it look like a SRT-8.....well guess what I did.
We are designing a remote mount twin turbo system for it as I type. Oh yea we just removed fuse 17 at 6:00 pm tue june 12...its now 6:22pm so what the hell am I doing still typing.

Where did you get your trailer package and hitch for your car? Install it yourself? Thanks

 

My RT AWD is 14.7 MPG on highway and 10 in traffic.

 

While I envy your having a trip computer, I wouldn't let it rule my life - well, then again...
I have an '06 RT RWD with 12K on the clock running Mobil 1 (since ~9K). Before that I had an '06 SXT RWD for as many miles on regular oil. Here are my observations:

*In the manual (okay, so it's not my observation) it states that to derive benefit from the MDS, speed should be kept at 65mph or less.

*And just an FYI, prior to their recent test revision, the EPA derived their highway mileage figure from a run at 50 miles per hour(!)

*Altogether, with the same type of driving (sensible - mostly), average mileage has come out straight up the middle of EPA estimates for both: SXT at 19/27 = 23 avg.; RT at 17/25 = 21 avg.
Whereas the 3.5 was a bit sensitive to passenger/cargo loads, the Hemi seems relatively unfazed by weight (as the 1mpg penalty hwy - none city - on your AWD RTattests; SXT AWD gets the same mileage!)

*I coaxed 30+ out of the SXT a couple of times and was disappointed that the RT with MDS didn't seem to want to go past 26. Truth was, I didn't have the heart (restraint?) to drive the RT in an optimal way for mileage.

*Driving a relatively level run for 145 miles on US-27 through rural Florida (mostly level) at 55 on cruise (except for Sebring and other towns), I consumed 4.8 gallons (of 87 octane!), obtaining my Holy Grail: 30 mpg from the Hemi.

Keep in mind that unless you affix a refueling probe and have someone on a tanker truck gingerly manoevre a drogue onto it while underway, your highway sample will be "contaminated" by non-highway driving (accelleration, from/to stations) at either end. This effect will be more pronounced on a shorter run; I went 200 miles at an indicated 3/8 tank consumed but then didn't fill up until I did a couple of errands, which sank what would have been a sweet number to a humble 26 mpg.

[Okay,I know:I'm hypermiling with a Hemi; call me perverse.]

Good Luck!

 

so far on the highway, i've found my 06 hemi r/t gets aroudn 22-23 mpg, but i have only actually figured out the mpg a couple times. in the city driving nice i pulled off between 14-15 mpg
