#5 of 14 New mileage info by habu Jul 08, 2006 (2:47 pm)
Since my last fill I have put on 270 miles, all in town driving. Not much stop and go, but all the miles driven under 50mph. Some stop lights, not much idling otherwise. What I find of interest is the trip computer for this tankful indicates the engine has been running for 11 hours. So I've averaged about 25mph and achieved 20mpg. I'll be putting about 55 miles on the Avant Monday and most of it will be hwy driving. Averages will probably go up some.

In their year-long 25K-mile long term test, the editors report having gotten 22 mpg with a 2005 A6 3.2
#7 of 14 Audi A6 2.7L "warm up period" ?? by archman2 Jul 24, 2006 (6:14 am)
After sitting idle for 4 to 5 hours my 2003 Audi A6 2.7L Turbo (which I just bought in May) has to warm up for about 2 minutes. If you drive while "cold" car barely moves past 10-15 mph. Audi tells me this is normal but I'm wondering if others exeperience this.   Also I get 12-15 MPG around town and 22-23 on Highway. Local driving seems very low. Others experience same?   THanks,   Andrew Replies to this message: sfcharlie (Sep 21, 2006 11:03 am)

Replying to: archman2 (Jul 24, 2006 6:14 am) Seems absurd to me to think of that as normal. I had a VW turbo for over 100K miles and (despite being a cheaper cousin to your car and an older model year) started up and drove normally all year round without any specific warm-up time. I'd call again and not even seem open to "is this nornmal? line of conversation. Just "I need to bring car in, have you let it sit for 5 or 6 hours, then start it up and drive off and diagnose what's wrong. When I do it, the car will not run properly; is limited to under 20 mph." Geez, I feel angry for you!
#9 of 14 Re: Audi A6 Wagons: MPG-Real World Numbers [pf_flyer] by 150mphclub Aug 18, 2007 (3:05 pm)
Replying to: pf_flyer (Jun 12, 2006 7:58 am) Numbers put up by any car's "trip computer" are notoriously unreliable.   First fill your tank. Then, next time you fill up, divide the miles driven by the gallons you put in. That is real world mileage. Anything else is a guestimate.
#10 of 14 My numbers agree by habu Aug 19, 2007 (12:51 pm)
Don't know where 150mph finds his data but my '06 A6 Avant's computer is always within .2mpg of my manual calculations when I fill her up. This is in the 22 to 24 mpg range. I have had the car 16 months and have 16,500 miles on the odo. The computer is less than 1% off (high). If every activity we encounter had an error rate less than 1% imagine how sweet life would be.
#11 of 14 2002 A6 3.0 MPG by ronm Dec 13, 2007 (1:37 pm)
I average 19.5 mpg with our 3.0. Mixed driving. Probably more city than highway. On an all highway trip I can get about 23. I've done the manual calcs and the trip computer is right on.

Replying to: archman2 (Jun 22, 2006 6:29 am) Is your car a quattro? My quattro got terrible milage around town - had the A4 the first year it came out. Hated it. They took it back on a lease and let me out of it because it was a lemon. The a6 is totally different and I was considering one until I read that the gas mileage was still lousy.

Replying to: dvpriem (Mar 16, 2008 9:19 pm) older 2.7T's w/ the twin turbo was a much thirstier car than the new 3.2 V6.   newer 2005 & up 3.2's are 26-27 on the hwy. I get around 18 in the city on my 4.2 V8. Had a 2006 and just traded for a 2008 4.2. I can still manage 25 + on the hwy.
#14 of 14 my experience by dman Aug 05, 2008 (11:03 pm)
'05 A6 3.2Q and have been getting 31-33mpg on the highway 65mph.
