Got 31.8 @ 80 MPH with AC on when I brought mine home from the dealer. So far about 27 average non interstate travel. I live in a rural area though, so not much city driving for me. I do drive at 4600+ in elevation also.
That would be true as long as overall circumference is the same and gearing then remains the same. The weight between them has to be realatively marginal though, right? That's kinda like pointing out you get better mpg when your car has a 1/8 tank vs. a full tank. Or if you have a fat or skinny passenger or no passenger....or if you had a big lunch.
Yes, weight all adds up to "something" that affects mpg.
23-24 mpg 40 mile round trip work commute. Mostly freeway miles. I have 20" wheels as well. Taking it to Vegas in a couple weeks to test out the 30mpg highway claim. I did notice that around 18miles into the drive the mpg starts rising.
When I was at highway speeds, the instant fuel economy did show 30 mpg when maintaining speed. What was better is when you let off the gas, it jumps to 80-90 mpg! Of course this is only "instant mileage" which only accounts for the gas being used and the speed of the car. As soon as you put your foot back on the gas pedal, it "drops" to the 30 mpg again.
Almost strictly city I'm getting about 17 but I drive "with purpose". Not punching it but usually first car off the line. On the 2 trips it's been on every bit of 29 or 30.
I get around 19 - 20 in city driving, however on the highway I have never seen 30 MPG. The best I got was around 28 MPG. Maybe its because I am 300lbs...lol..
Naw...It's more about speed, unless you have much more weight in the car besides yourself.
How fast do you drive on the highway? Do you use the cruise when you can?
If I set the cruise to 70 and just listen to the tunes, I get 31MPG consistantly.
3.07 rear end with the Rallye Redline.
At 70MPH my RPM's are about 2100/2200/
My sons SXT has the 2.6 something rear end and at 70MPH he's at about 1800/1900 RPM's and he gets 33/34MPG on the highway.
I'm averaging around 28-ish on highway drives. I drive about 300-500 miles at a time with most of it being interstate and Cruise Control.
However I do tend to be "first off the line" in the city and like to push the pedal down when I pass with Cruise on.
Overall I'm very happy with the MPG. I came from a 2012 V6 Camaro and got just a tad under this mpg but I can tell you that this V6 Challenger has much more response and kick (stock) than the Camaro. That surprised me when I first bought it but now a month later I still have to punch it harder than I would normally.
I would expect if I drove like I was trying to get the best MPG I could do much better.

I had a 2013 Mustang V6 and I never got over 24MPG on highway. Comparing it with a much heavier Challenger I can say that the Challenger does a pretty good job when it comes to MPG. I get around 27 MPG at highway speeds and 19 MPG in city. Cheers!
