What Our Members Are Saying about the Real Gas Mileage of the Dodge Challenger

Dodge Challenger Real Gas Mileage: Pros
YearBody/PowertrainComment
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
Dodge Challenger Real Gas Mileage: Cons

2012 2dr Coupe 470-horsepower 6.4L V8
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

4-speed automatic RWD		 The V-8 is thirsty for city driving. The extra power would be nice for highway & mountain driving, though. see full Mercury Grand Marquis review
