Year	Body/Powertrain	Comment
2011	4dr SUT 320-horsepower 5.3L V8 6-speed shiftable automatic 4WD	what fuel economy? bought it to pull a Brenderup horse trailer (3300lbs including 1 horse) that can be pulled with a 4cyl car in europe.... doing 22l/100km on flat roads with light foot. more than double combined rating ....GM unresponsive! see full Chevrolet Avalanche review
2007	4dr SUT 320-horsepower 5.3L V8 4-speed automatic RWD	14MPG in the city sucks. see full Chevrolet Avalanche review
2007	4dr SUT 320-horsepower 5.3L V8 4-speed automatic 4WD w/low range	It only averages around 14 to 15 in a mostly city driving environment. Was hoping the V4 mode would kick in more often to help improve the economy. see full Chevrolet Avalanche review

Dodge Challenger Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
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
