15 city and 20 highway. that is what is stated, but expect about 12-14 city and 17-18 highway or a realistic combined of about 15-17MPG. Best of luck, Hope this helps.
Yes, the 6.1L SRT engines don't have the MDS (multi-displacement system) that the 5.7L regular production hemis do, so it's 8 cylinders all the time for them, instead of 4, 6, or 8 depending on demand.
