In these days of high fuel prices and being "green", I love it when people
smugly comment about how my 911 TT *must be "terrible"
in terms of gas mileage.

Today, for kicks, I reset the car computer that calculates MPG as I entered
onto a limited access highway heading back from the Cape.
I drove for approximately 35 minutes, at speeds ranging from 60 -75 mph,
mostly 65-70 mph. *I didn't do anything special in terms of driving
techniques ... just drove normally.

At the end of the 35 minutes, the computer calculated mileage display read
"28.9 mpg".
My "normal" average of combined around town and highway driving is usually
about
20-21 mpg unless I have done some sustained "spirited" driving.

Not bad, all things considered, and the look on people's faces when I tell
them what it gets for mileage is usually one of disbelief.

It really is an amazing car, given 445hp, it's performance and it's fuel
economy.
I should drive it all the time.

For a highway only trip that is not surprising.. As you stated in
another reply to this thread that car is light and the body is
aerodynamically designed.

Let us know what the old fashioned (the method I use) method shows.
