What kind of MPG do you average on the Interstate? Please specify Auto or M6.

 

[monaro]

highway mpg

just got back from a trip to the coast approx 300 miles.
some in town slow down driving on the interstate but mostly 65 to 70 mph driving. used cruise control about 80% of the time. i was real pleased with 23 miles to the gallon w my 04, a4.

 

[DrFix2Fly]

26.1 MPG with 04 M6 during a 700 mile stretch at average 67mph

 

[HTRDLNCN]

I get 20-21mpg in an 04 A4 driving 70mph and my freind Jared gets 24-25mpg driving 75mph in an 04 M6

 

[Xcommuter]

I'm getting 21.7 average for my weekly commute. If I reset DIC from highway point a to point b - the average is 23.9 . Speeds range from posted to triple digit...

 

[Grey-Goat]

I reset my trip computer while I was on the highway to see what the average was for just highway driving. I averaged 24.7 mpg with an average speed of 69. 05 6 speed.

 

[EEZ GOAT]

all i can say is :willy:

 

[Groucho]

19-20 mpg, on average.

Straight freeway at around 70 is good for 26-27. If you can use cruise without too much hassle, do it as it's a very smooth unit.

 

[Cottonfarmer]

20.1 MPG on 4800 mile vacation. 80 interstate, 65 two lane. A4.

 

[rednred04]

25mpg ~2500mile trip -- mostly a little north of 70-75mph

 

[toolman]

Just went on a 300 mile trip and got 23.5 on hwy with a 2004 4A. Cruise on all the way.

 

[Hi Speed]

If I keep the air off I get 25.5 on the hwy, and 23 in the city
I usually travel at the posted speeds or above at times.

With the air on I usually lose 1 - 2 mpg depending on the ambient temp. :cheers

 

[AggieGTO]

I just made a 450 miles round trip over the weekend and got ~23+ mpg in my '05 with M6 with just over 2K miles on the odo.

 

[sno-rydr]

on my most recent trip from seattle to provo, ut, i drove a touch over the speed limit on the way down and got 28 on the best round. on the way back i was less patient and had the ac on for a good portion. sometimes speeds were around 90 and i got 26. not bad at all! any time i do much driving in town at all, it goes down quick. city driving gives me around 17-18.

 

[fergyflyer]

City is about 17-18. On the highway with A/C on and cruising at 80-85 on several long trips I averaged 23-24. These numbers were calculated using the exact gallons used from the pump, not the DIC. They usually matched though.

 

[fat nick]

M6. 28-29.

 

[04m6_ca]

20 - 21 avg. 39mph. avg. 108mi. per day.

 

[GTODEALER]

With ls6 cam, l.t.'s, underdrive, cat-back, cai..... on a long trip 1600+ miles, I averaged 29 mpg..... :cheers
