i have a new (less than 1k miles now) 2011 S5 prestige automatic. have been driving it for a few months now, great car and liking it a lot. however, i noticed the mileage is pretty bad (~12 mpg). my commute to work is a local commute less than 5 miles each, in the morning i take the freeway for most of that distance and then go local on the way home.

i don't drive the car very hard (no sudden acceleration or braking) and purposely drove it very carefully on this last fill up (premium of course) in order to try to maximize MPG and am looking to only get about 200 miles or slightly less on a full tank of gas. how much are other owners getting on a tank of gas? any feedback would be much appreciated. i realize that you never get the mpg advertised but 12 mpg seems pretty low.

I have a 2011 S5 coupe with a manual transmission and my commute is 10 miles, the first 3.5 miles is suburb streets and the rest is highway and the computer says that I get about 18.5-19.0 MPG to work and about 16.5-17.5 MPG on the way home. The computer tends to be about 0.5-1 MPG optimistic.

I usually get about 200-200 miles from full to 1/4 full. I never let it go below 1/4, just a habit of mine.

I have just about 7K miles on my 2011 Coupe with Tip. On a recent trip to my parents (SF Bay to Carson City and back) I got around 22 mpg on average. The trip back was about around 250 miles and I was just below 1/2 of a tank when i got home. When I finally filled up I was at 291 miles and it toook 13.3 gallons. (21.8 mpg)

My commute is mostly highway, about 15 miles, and I average 17 mpg or so. usually at around 200-220 miles at 1/4 tank.

At 1K miles you are still breaking in the engine, it will get better.

I usually average around 13 to 14 in town... or 15 according to the highly optimistic computer.

But by the REAL numbers, 14.5ish in town and I've gotten as high as 27 on an extended drive in perfect conditions. The S5 I think has the biggest swings in fuel consumption of any vehicle I've ever owned. It can get great highway mileage, or absolutely horrendous city mileage depending on the weight of my foot. I've had tanks that averaged 11mpg a couple times. :)

I actually track and calculate my MPG using an iPhone app so it is a bit more realistic. I have 1500 miles on my S5 and I have been getting about 18 MPG on average which works out to about 300 miles per tank. I drive around 40 miles per day round trip to and from work and it is almost all interstate.

I average 150-180 miles to a tank, the lowest ever was 130.. My commute is 8 miles of stop an go traffic, with about 20 red lights so I dont expect much, if i wanted good gas mileage I would have bought an A5.

I recently sold an RX-8 that only averaged 18 mpg on my ~60 mile daily commute of 50/50 Interstate/local driving. Although I'm sure I would have enjoyed the S5, the seemingly every other day gas station pit stop was not to be repeated for me and hence my A5 selection.

Most likely why it's presumed the 2012.5 S5 will have the S4's s/c V6 under the hood. The n/a V8 is sweet, but just too fuel consuming.

Depends totally on City vs Freeway. Transmission. Traffic, Mileage etc.

I am at 8K miles. 6 speed. 70% freeway. I am around 250-260 a tank, driven fairly agressive and that is driving it til "0 miles to empty"

11,500 miles. 6-speed. 250 a tank with my normal daily drive. Closer to 300 on a long highway trip.

thanks for all the feedback guys. i knew less than 180 miles per tank was just not normal. i took the S5 to the dealer and after an inspection they said something was wrong with the fuel pump. i'll have more details after talking to the tech when he installs the new part (not in yet), but a bit disappointing to see the car having an issue just 1k miles after leaving the factory.

I just came across this thread and I am astonished at some S5 owners feedback. I own myself a 2008 A5 and I have gotten 230-240 miles per tank shifting fast into 6th gear and driving at speed limits, taking my time to commute to work and my commute to work is 98% highway, so there is no freaking way that a gas guzzler V8 S5 will get anything above 200 miles per tank under any whatsoever driving conditions which led me to believe that gd10 may be the only true S5 owner out here.

i'm surprised you get such poor mileage on the A5. the A5 has a slightly larger gas tank (16.9 gallons vs. 16.6 for the S5) and should be getting (real world) at least 19 mpg = 321 miles per tank. i'll post my new mpg once my fuel pump is fixed.

Guess my 2011 S5 Coupe is a fluke then... 219 miles, 12.5 US Gal (3/4 tank) when I filled up yesterday.

i doubt your mileage will change.. less then 200 is normal S5 fuel mileage..

what do u mean a fluke? gas mileage depends on driving conditions.. you can get over 200 miles if your cruising at steady speeds and not stop and go traffic

according to other owners that have posted, some are getting well over 200. the mileage will get better, it can't get worse because after the last fill-up it was on a run rate of getting 150 a tank, which is clearly not normal.

Just giving GuzmanA5 a hard time, he cant believe the S5 can get that kind of mileage... I know it is not a fluke ;)

My 2011 S5 gets 250 to a tank...driven most in Dynamic mode AND I often am in 4th gear at 65-70 on the freeway....

I am 65% Freeway I would say.


Also....I have heard several times the newer S5s are far better on MPG then the early 08 and 09s.


On fuelly I get a mixed 17 MPG. Even the S4 ownerns that talk about the superior MPG of the V6T MIGHT get 18.5-19. Boost is a bitch.

if you own a S5 and your concerned about gas then you bought the wrong car.

that's absolute "lead foot" mileage. you can EASILY get over 300 on a tank. I did it MANY times. My highest ever was 349.

MPG best was 23+ cruising at 75.

Here's a shot I took after ~22 miles and a reset. Other members have gotten up to 29 MPG as well on another board.

resetting it and taking a picture of your mileage doesnt mean your getting 29 mpg.. i can reset mine going down a hill and it will immedietly show over 100mpg...

over 300 is only possibly if your cruising on the highway.. its impossible with local driving

That photo is not of instant MPG, its sustained. Why would anyone find it useful to post the instant MPG reading? :rolleyes:

im not talkin instant miles per gallon... if i reset my mpg and im cruising at a steady speed the first reading the MPG is going to say is well over 100mpg... the only way to determine actually mpg is calculating how many miles you covered on however many gallons you had in your tank... the computer is never accurate and you never got 29mpg.. sorry just not possible

Reread my post and take a look at the picture again and you might just find out you suck at comprehension.

BTW, nice straw man argument.

Op didn't qualify w city driving.

calling bs on this one-----sorry- have to agree with gd10- an S5 will never average 29mpg. you can't fool those who've owned one. 22 miles might be enough to get a 'relatively accurate' reading if you are on level ground; but you could easily have hit the reset button going downhill (while in averge mode), to display that amount.

i can take a pic of my Q7 going 70 mph and make the AVERAGE mpg show 40+ mpg.....

weak defense.

- reset the trip odo 22 miles ago.
- reset the avg mpg at the top of a hill.

who are you trying to fool?

LOL, I don't have a reason to lie to anyone here. This car gets horrible MPG, there's no denying that. I could take a video, but it's not that serious to me. That video was taken on my drive home over 22 miles. I've also recently taken the car on a 800 mile road trip and averaged 26 mpg without extensively trying to hypermile.

I'm not the only one who's claimed to have gotten high 20's MPG, even in this thread. There's also people on a5oc who have posted threads displaying similar MPG.

read your links---27 cruising at 55 is achievable. However, 55 will get you run over on the highway. If you'are at 70, that might be in the 24-25 range.

THE other posts of 28, 29 and 30+ mpg---did you see where those posters lived? HINT--that should be a clue... ;)

Straw man. 29 MPG is achievable. Fin.

beh. I bet you didn't look up that the UK posters' Britsh gallon is 20% greater in volume than a US Gallon. Thus 30mpg (British) is actually 25 US MPG.

use your "straw man" escape when you can prove it.

Sure did read that poster's location, and also the location of the other posters from Illinois and Florida who also indicated similar MPG. So the fact still stands, 29 MPG is attainable per the computer (accuracy is another discussion).

I'd also have to believe 29 is attainable depending on speed. I've averaged 27mpg at 65-70mph on less than level ground on a stretch of interstate here that I drive often. The computer is usually about 1mpg too optimistic so that probably equates to just under 26 actual MPG.

At 55-60 or so I could see getting it up to 29 on the computer's measurement...

There's no "fact," based on the limited basis you pose. And there is no IL poster who claimed 29 (it said 8.9). The FL post is skeptical at best. If that is your basis, since i see nothing else, it still is a weak position.

regardless, we'll simply have to agree to disagree.

Wow....that's fantastic mielage. I had'nt seen more than 23-24 mpg after driving the S5 extensively.

in the end your not getting 29 mpg, it takes more then 22 miles to get a actual average and its not possible to get over 400 miles to a tank even with all highway driving.. ive driven my s5 30,000 miles, on several long roadtrips and Ive never seen over 350 to a tank(on a highway only trip) and I work for Audi so I feel my opinion has some meaning.

I'm getting a total average of 20.9mpg. I have just 5k on the odo and is a '10S5

I'm getting a total average of 20.9mpg. I have just 5k on the odo and is a '10S5

thats a good average with not to much stop an go driving.. im averaging 12mpg, but its 15 miles of stop an go, 20 red lights a day.

My daily commute to work is 22 miles and I average about 22.4 mpg. I get 293 miles per tank with my daily commute and running around during the day locally for my job (sales).

When I drive up to my lake house in Michigan from my house in Illinois (150 miles) I average closer to 27 mpg and get around 335-340 per tank. My driving style is aggressive. Lets just say I never get passed on the highway.

Most of the mileage numbers here are crazy to me.

I am lucky to get 220 miles out of a tank - that includes some highway and a lot of city.

Usually I am closer to 200. In fact, when I first got the car I ran it out of fuel twice because I didn't believe the dash telling me I had 0 miles left.

When I go total highway trip which I do a lot I get to about 260 miles on a tank. I don't think I have ever had more than 275.

'08 6MT driven like the world is a racetrack. But still 6th only on the highway. Highway speed averages 80.

I think this thread just goes to show how badly Audi missed the proper 6th gear ratio or final drive- or both.

Since I've installed the AWE s-filter I have been getting about 1-2 mpg better. Just in case anyone is looking for a small boost in MPG. :)

So which gets better mpg, the V8 or the new V6t which is in my soon to arrive S5 Cab. I thought that part of the allure of the V6 was almost the same torque but better gas mileage?

i havent heard anything good from anybody about gas mileage from that motor....If you care about gas mileage then you should have bought an A5.

+1 - Even my '04 BMW 330Ci revs a little lower in 6th. It doesn't have the power of an S5 (BMW specs it at 5.9 sec 0 - 60) and it has plenty of power on the freeway (doesn't required downshifts to accelerate on steep inclines). I almost never use 5th gear. During regular driving the car's gear prompt generally suggest skipping 5th and shifting to 6th at 1500 rpm or less).

My gas mileage experience:
I just filled up my S5 (always wait until the fuel light comes on = 14.1 - 14.5 gal) at 270 miles, 44 mph average, 20.3 mpg computer, and 18.9 mpg manually calculated. My car has 6,500 miles. I reset trip computer 2 each fill up and manually calculate the mileage. The trip computer adds between 1.2 and 1.8 mpg to actual at 17.5+ mph. The best calculated mileage I've gotten on a 14+ gal fill up was 23.5 mpg (52 mph avg). The worst was 13.6 (22 mph avg). The best I've seen on the computer for a single 70+ mile trip (trip computer 1) was just over 26 mpg (probably 24.5 real) with a low 60 mph avg. An average 25 mile drive is about 20 min on the freeway and 10 min on secondary roads with lots of stop lights. I drive 77 mph on the freeway except through Camp Pendleton where I drive 82. Being SoCal, I usually have a little stop and go traffic. I almost never get less than 200 miles between fill ups. I'd say my average is 250 miles which is about 17.5 mpg. I'm kind of interested to see what mileage I would get if I stayed between 65 and 70 mph on the freeway. I noticed a significant mpg increase in my BMW when I tried this.

Too late now!

I drive like an idiot, my guess is about 17 mpg.

??

you can easily get 28+ cruising 70mph all day long with the V6T.

If you want to play with the car, don't expect 20. That would be insane thinking. =)

I tried a little experiments yesterday, I left it in D and babied the throttle and went for a little 100 mile drive out the interstate, and I averaged 29.2 MPH for the trip.

With the same trip in S I'm sure it will only be about 21, but overall I left the trip odo#2 running since new and I have 5700 on my '10 now an dI am averageing 20.8 showing a range of 385. So add in 8% lets say if you run a babying tri[ and the range should be 415 + or -.

Hope it helps.

If you are a constant lead foot . . . good luck getting to the next gas station.

see my other post in this topic. But you can get the same MPG out of both engines.

I've had my '09 S5 for about a month now. I've taken it to work about 3 days a week, which is a 30 mile commute. Roughly 2/3 is on the highway, and the remaining 1/3 on local roads about 35-40 mph with some lights. My computer usually says around 24.5 mpg by the time I get to work. On a recent trip down to Atlantic City, I managed 26.5 mpg.

However, when I refilled the tank and calculated the mileage based on the odometer and amount of fuel put in the tank, it was more like 20.5 mpg. I see most people have a discrepancy of about 1-1.5mpg, but mine is over 4! Anyone know why? Or did my attendant not fully top off the tank? (I live in NJ, so I don't pump my own gas).

Also, has anyone done a comparison of 91 vs 92 vs 93 octane? I typically go to Wawa, which has 92. Audi recommends Shell, but they are usually 20-30 cents more per gallon than any other gas station. The one take I filled with Shell, I noticed no difference in idle, acceleration, smoothness of the engine, or gas mileage.

I haven't filled up with anything but 93 and that I usually do at Turkey Hill (don't ask why they are considered 'top tier' for fuel, but they cost the same as the 92 stuff at Wawa or Sheetz stations. I don't think it would make anything more than a negligibledifference and doubt if you could feel a performance/economy difference either.

I just made my maiden out-of-town voyage, and fill up the tank full. 75% highway driving, 25% curvy mountain road driving (some steep and hilly). At 308 miles, I refueled and replenished 14 gallons. This translates to 22 MPG. Not bad.

Thing is - I put 5 gallons of Exxon 93 and don't know what my dealer put for the remaining 12 gallons.

Today I put in Shell and I'm getting 390 Miles to go. Then, I traveled 35 miles and still have 365 miles, so it seems that Shell 93 might give me 400 miles on a tank. Let's see.

I have not pushed the car but on two occasions, hitting 103 and 105 mph, since there's less than 500 miles on it.
