I drove from Austin to Woodland Park, CO and back recently. I have an '08 and the 200 ran great at 2,000 rpm in 6th gear which put me at 82 mph. This seemed like a good rpm for the motor on the hwy. My old F150 with the 4.6 and 4sp auto liked 80 mph highway speeds. I don't care about mpg. My dad said his old BMW 2002 drove better at 80mph than at the old 55mph TX speed limit. Does the 8sp auto in the 200 like to run 80+?
