I was wondering what kind of mileage you all are getting on your R/T's AWD or not. I have a brand new R/T AWD. I just filled up this morning right before I got on the expressway. I merged on, accellerating steadily and smoothly and continued to run at 75mph for 20 miles and only got 21.3mpg. Is this normal? I thought this thing was supposed to get 24mpg. I was expecting more. Will I get better mileage as the car breaks in or is that was I should expect. The outside air temp was 48°. Thanks in advance for your comments.

 

Don't trust the computer, mine shows .5 to 1.5 MPG HIGH....better to do the math when you fill up.

I average 17.5, mostly secondary highways at 60 MPH, not aggressive but passing when needed, with many slowdowns for small towns, 8 towns/villages on a 33 mile commute. I wish I could get a real 21.3 MPG, that is about what I get with my AWD Passat.

But I don't care, I just grin and bear it, because it's a Magnum.

 

Yep, that sounds about right.
Wife does not drive hard, and the best I have seen on the computer is 21.
4,000 miles on, will start checking mileage for kicks.

 

As your engine breaks in your milage does get noticable better. Our other car was averaging 16 at first, now at 5k miles its in the mid 20s. I personally would be happy with 21 from a hemi, even though it is MDS.

 

you didn't say what engine you have. After 350mi on my 5.7 heml ls only getting 15.5mpg-(math)
I'm taking it on a 1000mi drive this weekend hope it improvws.

He mentioned he has an RT-AWD, so hemi power!

Olddad, how do you drive it? I would guess not "grandpa style"?

 

Crazymjb- your right. I thought you could order the R/T with the 3.5 V6. Thankx
I drive it through an easy warm-up, then I put my best foot forward. Have not done any WOT from a stop but have run it up to 100 getting on the interstates.

Sounds like I am right in there then. Just seems funny that our Volvo XC90 with a V8 gets better mileage. Thanks for the info.

 

Well the volvo is running of a 4.4, which makes 29 less horse power and 65 fewer ftlbs of torque then the 5.7 and is only hauling about 500 more pounds. So a slight MPG increase would be expected, especially with the limitations on the MDS(6 minute on time, off during high speeds and most acceleration). The RT will also take Plus while it is probably a good idea to use Premium in the XC90, which brings operating costs even closer.

 

I have an RT Hemi and the very worst Ive gotten is around 19mpg. I get over 25 on the hiway on trips all the time. I generally never use A/C and only myself or one passenger most of the time. I got 20 mpg towing a Ferrari 308 on a dolly from Columbus to Pittsburg on interstate with cruise control.
