2012 2dr Coupe 470-horsepower 6.4L V8
6-speed manual RWD		 Better than I thought I would get out of a Huge V8. It is my Daily Driver so I do fether the pedal sometimes. If hypermiling I can get 27 to 31 highway and a combination of 23mpg total......if I can get through a tank without opening it up. see full Dodge Challenger review

6-speed manual RWD		 I think they could have made the 4 cylender deactivation for the Manuel as well and improve gas milage. see full Dodge Challenger review
2009 2dr Coupe 376-horsepower 5.7L V8
6-speed manual RWD		 City milage is not very good and it is so hard to stay off the gas. see full Dodge Challenger review
