Real World Miles Per Gallon

[Lucky]

My 2000 S averages 20 mpg in mixed use -- 60-70% back roads/in town, 30-40% highway. All quite spirited... it is a Porsche after all.

I've never taken it on a long highway trip, so I can't give a scientific # for pure highway. Based on my average, however, I think it achieves around 25 mpg at reasonable speeds.

What I find surprising is my 1986 Carrera 3.2 achieved slightly better mpg on my commute -- in the 21 to 22 range. It was smaller, lighter, less powerful, and had narrower tires (in back) which probably explains the difference.

Then there is my commuting appliance -- civic hybrid -- average 42 mpg, but ideal weather (60's, dry, no wind) mpg is in the low 50's.

Spirited driving:

2006 Boxster S.......about 22MPG
1997 911 Turbo......about 16MPG (that's why back in 1997 the first owner had to pay a $4,500 gas guzzler tax!)

This is another situation covered by the saying, "Read the fine print." The fine print says, in essence, actual mileage may vary depending on a whole lot of things.TrueDelta's Gas Mileage Survey (formerly the Fuel Economy Survey) is the only one to ask car owners about driving style, terrain, A/C use, driving speed, and other factors that can affect actual gas mileage.
