I wonder if the 2010 will get any better gas mileage. Pretty much the same drivetrain, but maybe the aerodynamics will be better. I would like maybe 1-2mpg more. The new camaro v6 is predicted to get 27mpg w/ a 300hp v6 and the challenger R/T is getting 25mpg with a 5.7L v8(highway). Ford should step up the fuel mileage a little.
