122 mile round trip and I wasn't driving like a nun either. Very impressive for a car with the performance it has.

Everyone should post their Fuel computer 2 average pictures ;)

I suspect 95% of owners will fall in-between 26-32mpg
 
That is impressive. I've always found VX/Audi engines give much better fuel economy that most other makes!
 
Average over 8500miles is 32.4
Got 44.3 cruising to the airport yesterday, approx 75miles sitting on the mway for most of it at 74mph.
 
Gotta say 40mpg is damn impressive :)

I'm kinda blown away that a 300hp car is likely to annihilate my 2ltr Petrol Rav4 (with it's mighty 115bhp) on fuel ecomony. Just shows what 10 years of technology in the motor industry is capable of ;)
 
This thread has had a good run without someone chirping in to tell you you've bought the wrong car if economy is important to you ;-)

You have photo shopped that Photo.............lol never got over 32 on any trip......average 24 mpg which is terrible....@2k miles, and super unleaded makes no difference to the mpg or performance in the S3 it did in my last car

Hi mate,l do think the S3 has terrible fuel consumption,S3- 296 BHP, ST -252BHP- 44 BHP difference and 10 mpg difference and l drove the ST far harder than the S3..........
 
I got 40mpg the other day on a trip to York. However my average computer 2 is 22.9mpg over 1500 miles! Shocking!
 
Since being stopped by the Rozzers at the weekend, my MPG has jumped from around 25 to 33.

OK sweet, so new users can expect mpg of anything between 22 and 40!!

I'll take 31 as an average........do me nicely ;)
 
30.7 average 2k miles. Lots of naughtyness in there too :)

I would be thrilled to average 31. Anything is better than the 16.4 I am currently averaging. May have to file for bankruptcy.
 
My MPG is currently worse than my 8p s3. I thought it would be quite a bit better. Damn it.

Not having the aerodynamics of a breeze block helps. ;)

My average over 16k miles is 29.2 MPG, not bad at all; it's beating my A3 8P by 2 MPG despite being 100 bhp more powerful.
 
I'm averaging 32 over almost 10,000 miles. I drive into central London and back every day, plus a fair bit of motorway at non-economical speeds. I hammer it when I get the chance, that's not very often given the roads I drive on. I can get 40+ on a run if I drive very sensibly. If you're getting low 20s and are not ragging it constantly I'd suggest there's something wrong and I'd take it to Audi. Overall I'm really pleased with the economy, it's not much worse than my old 8P 2.0 tdi.

That's a very good point, I drove my wife's company BMW diesel harder (as it was slower) and got not a lot more than the S3. Performance only uses lots of fuel if you use it, the S3 is only a 2l lump so isn't by default thirsty until you use the throttle. Diesel's drink fuel if you are on boost all the time, for me averaging low 30s with the S3's performance in reserve is impressive not that I give a monkeys................
 
Here's my average from the day I drove it out of the showroom - I've not reset it. The difference in mileage is down to the dealer, pre-delivery road checks. I suspect if I'd reset it at 10,000 it would be more like 32/33mpg. I commute 60 miles a day there and back to work, I usually average between 31 and 35mpg, traffic and road conditions permitting. Note the Warning light that appeared this morning! Audi assist are on the way- car's telling me I have a safety system failure - what ever that is... Radio Two today :sm4:

Wow I am actually impressed by this thread. I read some other threads where people were saying the S3 gets terrible gas mileage like in the teens. Most people here are reporting 25-35 and some even higher! 30 mpg average on a 300 hp car is something that was not even remotely possible back in the day. My Supra has about 300 hp and gets 16-18 in daily driving and my best tank ever was on a full tank of freeway cross country driving (380 miles from 16.5 gallons) which is about 23 mpg, but that was at cruise control 75 mph the whole tank, so a best case scenario.

S3 goes 0-60 in 4.7 seconds and gets 30+ mpg. that's pretty awesome.
 
Dude, gas, freeway, awesome - I guess you are from across the pond?

Just to bare in mind that UK gallons are different to your US Gallons (4.5 litres vs 3.7 litres) - 30 UK MPG = 25 US MPG

Audi quote 41mpg combined for example, most owners will fall well short of that at around 26-32.

Yes, still good for a 300hp car though
 
Almost 400bhp and....

What does your fuel computer 2 show Dandan?

Pointless quoting single trips, we can all drive around off boost in neutral going down hills. Let's be honest here, you never got 43mpg using 400bhp did you ;) I doubt the turbo even spooled.

For future owners reading in, you really need to quote real time averages and seeing as you do a lot of 0-60 type stuff, i reckon yours will be around 30?

yah I'm in Cali... land of watered down 91 octane. ugh. :frown:

but this is good to know... that if I want to take a lil road trip the S3 would deliver those kinds of results.

I'm so back in forth between S3 and S4 it's not even funny. :shrug:
 
Well my S1 would get at best 25mpg.

I suspect the S3 will be less or similar. Neither me or the wife will drive it like a nun.
So long at it goes where we want to go, who cares about the mpg.

We'll take the g**f tdi when we want to save a few pennies

Bear in mind also that US octane is not the same as EU octane, we quote RON, while in the US you have MON, which is roughly 5-6 points lower for the same fuel. So Cali 91 octane is roughly UK 96-97 octane. Not amazing, but not as terrible as you might think at first glance.

ok you guys are really enlightening me about these differences in measurement UK vs USA. First, I did not know about the difference in gallon (mpg). Second, I definitely didn't know about the octane rating diff. I was wondering why APR stats claim that 93 octane produced the lowest HP rating on their chart, and I was thinking... dam... that means mine would be even LOWER than their lowest. lol

Now I see what's going on. Thanks for that info. For the record (which you probably already know) we used to have 92 octane in Cali, but they dropped it to 91 years ago. I think some other states over here can get 93.
 
Fibble's post is slightly misleading..

US91 = UK95 (The lowest quality petrol in UK, will lose you approx 10% of power output in an S3 if run on this fuel)
US93 = UK98 (Higher octane - What performance cars are tuned to run on and what the S3 makes its full 300hp on)

We also sell 99 octane fuel here in UK, there used to be 102 octane aswell but it was very expensive so didnt sell well and was pulled from the market
 
After a motorway run of 120 miles and 331miles overall on one tank, I filled up and the range said this.
Actual calculations between fill ups is 38mpg, the computer was showing 40.7mpg for the same. Yes, I did drive like a saint and averaged 77mph on motorway. Just 'cos you have an S3 doesn't mean you should be driving it aiming to come off corners ;) For a supposed pig of a car with crap handling, bouncy suspension, numb steering, boring looks, rubbish interior and the fact it's not a Golf R - I love my S3, ticks all the boxes for me.
I might even go for the RS3 as the replacement, but I'll make sure it is given at the very least a 24hr test drive before signing on the line.
Anyway, amazing!

My 2014 S3 averaged 31mpg over 7500 odd miles in the 6 months I had it.
I think that's pretty good... but I haven't had two of these expecting anything else, mpg wise
 
Trip 2 is on 34mpg over around 1000 miles. Best ive ever seen on a 15 mile run taking it steady in Auto on drive select is 47mpg!

I regularly get 40mpg out of it plodding along to work at 40mph.

Run on 98 octane Shell V power Nitro + exclusively since 200 miles in, with an open cone filter!

Your wasting fuel doing that. The engine will be at idle rev's and using fuel. If you lift off and coast with the car In Gear and the clutch engaged then the engine will not use any fuel at all
 
  • 14,715 miles of V-Power/Nitro/Whatever they call it now...
  • Average 33.5mpg for 2

Actually, you guys quote an average of RON and MON on your pumps.

Both UK Shell V-Power and UK Tesco Momentum 99 have (minimum) 99 RON values.

However, the MON figure is derived from a more demanding test, more reflective of todays engines, with higher RPM, higher head loads imposed during testing.

In this case, UK Shell V-Power has a 86 MON and UK Tesco Momentum 99 has a 87 MON.

In the UK, we only display RON on the pumps, but in the US/Canada and a few other places, the display is (R+M)/2, hence why you see different figures on the pumps across the pond.

This isn't universally true. It depends on your specific journey, and what distance you are measuring this over.

In the "E" mode of the S3 it will utilise coasting (clutch disengaged, idle revs) to improve mpg.

Also: During coasting or braking in the A3/S3, the power management temporarily increases the charge voltage of the alternator to boost the battery charge (assuming it needs it), then during the subsequent acceleration phase, it draws its current needs back out of the battery, temporarily de-coupling the alternator of its duties. They reckon they achieve 3% better fuel economy with this system (It's an AGM battery).
