I'm assuming you have the 6-cylinder engine? 1600 RPM at 60 mph is a very low engine speed. My car is doing 2600 RPM at that speed in 6th gear.
1600 RPM at 60 mph is 26.7 RPM per mph. This would equate to 2133 RPM at 80 mph. So, if you are around that RPM when in auto-shift mode, then the car is getting into 6th gear. At 75 mph, you should see an even 2000 RPM.
Auto transmissions generally rev higher than ideal on purpose, because the consumer demands quick throttle response. People would complain if the car accelerated slowly at low RPM while they pressed the gas pedal 3/4 of the way.
