Round trip milage for R/T auto this weekend was 23.72 mpg
a bit worse to my destination(of 190 miles) 23.05 mpg but coming back I got like 24.38 or something like that. Not bad for the power and weight of the car. BTW , if I wanted better mileage I would have chose the v6. A supercharger tossed on one of those may me the answer for a Mileage concious Challenger owner. JMO,
