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.

I'd be very happy with 20mpg. My X5 4.8 has horrible gas mileage - 18
average. We did order the Z4 3.0si - not as a replacement - and it is
advertised as 18/27. It will be interesting to see what the real number
is.

I think the Porsche's advantage is light weight, aerodynamics and an engine
that is basically loafing along at 75 mph.
It isn't even breathing hard, the turbos aren't doing anything and it's
operating at a fraction of it's capability.

My '90 Grand Marquis (Colony Park) wagon will get 23-24 on the 4 lane
w/ cruise on 65. Use air and it drops to about 21 +/-

the wifes 2003 Chry Town and Country only gets about 23 w/air on and
65. So I figure that even though it's still lousy by todays standards,
I'm not doing so bad, besides. It will pull my boats

I tease Mrs. E. about her Navigator. The best it can do is around 12 mpg,
regardless of how light your foot is.
However, it *will* pull a boat or trailer.

It sorta cracks me up. Of all our vehicles, the Porsche, with the highest
horsepower and performance, gets the best fuel mileage. The Sprinter
(Mercedes diesel) RV gets second best, followed by the Ranger PU, her
Navigator, the old GTO and the old Ford. The boat comes in dead last.

Actually, the Harleys get the best mileage, come to think of it. I just
haven't done much riding this year yet.

maybe so, but the fuel to weight (not counting "protection") still
blows.

Actually my boats get the best fuel mileage....but then they still have the
Rock River here in Winnebago Co., Il. closed. The DNR opened it last week
but the sheriff (wisely) issued a "no wake" limitation. That, along with
the fact that all of the boat ramps are still under water and closed,
effectively kept the river closed. Now, the rain, here and in Southern
Wisconsin has caused the DNR to close it completely again. Expected to go
back up 2 ft. in next couple of days. I'm afraid to see what additional
erosion my river bank has experienced.

I think this is the range that we're in. We have the Mercedes SLK-55
AMG (5.5L V8, 360hp) and it get about 20mpg regardless of where or how
it's driven (well, unless I get 'spirited' - then it DROPS.) Luckily
we have a Jetta TDI as our daily driver and that hits the 45-47mpg
range. I wouldn't want to have to drive the SLK (with the premium
gas) to work everyday !

You are doing about as well as I do in a 2 liter Honda Prelude (avg
about 23-24). I can squeeze 31-32 out of it if I use all the "Mobil
Gas Economy Run" tricks I know, not stuck in traffic and stay off the


Frankly, I am not sure I believe the computer. I just filled it up and will
check it the old fashioned way ..... mileage driven, gallons used.

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.
