I'm surprised that the Intrepid R/T and the 300M get about the same (or worse in some cases) as my Magnum SXT with the 3.5 .... I have actually gotten between 26 to 27 mpg with the cruise on and keeping it under 65 mph. City/Hwy combined I get about 21 mpg avg. Highway driving about 25 mpg avg. I use the recommended 89 octane. So what gives? The Magnum is about 500 lbs heavier and not nearly as aerodynamic as the LH's. I notice the LX's have a redesigned intake (and it's about as ugly as all get out) as compared to the LH's. Could it be that it is more efficient? Or does the transmission on the LH's eat more power? Now my 2.7 Trep used to get up to 31 mpg hwy if I took it real easy.
