Not enough miles on my new car to really get a good idea due to motor breaking in but my normal base R/T with a fresh chance of 5w20 royal purple full synthetic was regularly averaging 28.4 @ 70mph over a 430 mile drive. Hand calc. Mileage didn't really start getting good until about 4000 + miles for me. Evic read over 29. (That was also without stopping so YMMV.)
Brilliant White 2012 R/T Murdered by cow on 10/9/2012 @ 20024 mi.
Cow Plow 2 is a 2012 Redline 3 coat 2012 R/T R&T STP with normal options.
the best i ever got on the highways was 27.6 mpg with MDS (before my tuner) my average is 14.6 with MDS off, took the tuner off, so I expect it to go up now!
Honestly I say go with what you want, if you like power, go with the RT if you want a car that will get you there and back, either one will work
I am excited to see these numbers. I am getting my 2013 AWD R/T this weekend but currently have a V6 G8. I am only managing 20-21 mpg average. (17/25 epa estimates). I am thinking I might be able to get close to that maybe 19-20 average. I'd be happy with that considering I am gaining 150 ft. lbs of torque and better gearing.
All these numbers are subject to driving style. From what I see it looks as though everyone drives like a little old lady! My commute is 30 miles each direction with 15 on the HWY and 15 in town. I averaged 19 before mods, no one beats me off the lights or passes me on the HWY!!!
