S3 Realistic MPG

In efficiency though when maintaining motorway speeds it shouldn't make any difference right? unless you are constantly taking foot off pedal to coast, though then you would have to speed up to accelerate so probably makes mpg worse.

If you're maintaining highest gear and not coasting then not sure what difference the drive select modes would do.

Impressive figures anyway!

(I drive efficiency 75%+ of time)
Traffic was (as always) heavy so was often disengaging cruise control and coasting to gently slow down and then re-engaging cruise to pick up speed which is does really slowly in that mode.
I was surprised at the mpg, especially as Birmingham to Manchester is uphill all the way...….

Real world reviews of the AMG A45 seem to suggest far better economy. I've seen comments of people getting 25+ mpg on city commutes. I'm lucky if I get 15.

No two commutes are the same though so we're not comparing like with like. My commute is only 2.5 miles but, if it's heavy traffic and a cold day, I'll get 17mpg, whereas if it's lighter traffic and warmer weather, it'll be more like 24.

My car isn't an S3, its the 2.0 TFSI 190 but just for a comparison -
I don't normally use the efficiency mode but used it today for the motorway trip from Birmingham to Manchester driving at 70mph and 50mph through the roadworks using cruise control. It was a 74 mile trip, fuel consumption was 59.7mpg according to the trip computer. The return trip was much slower with very heavy stop start traffic but still returned just over 54mpg.
For a reasonably swift car (albeit not in the same league as the S3) I think that's pretty good.
Was a very boring drive though and the "free wheeling" is a bit disconcerting.

The trip computer lies. Do the maths manually.

No, but all commutes are similar, so it's pretty easy to infer an average between vehicles. People report heavy traffic commutes of 25mpg in the A45, something that isn't possible in an S3 in any condition.

But everyone's definition of heavy traffic is different.

Both cars have very similar engines - turbo four-pots pushing out over 300bhp. I find it very hard to believe that Mercedes have magically managed to make theirs massively more efficient than Audi are able to.

Yeah also I looked on that honestjohn realworld mpg website, and the S3 shows as more fuel efficient than the A45...

Like someone told me on here if you can only just afford to buy a performance car like this, then obviously you can't afford to run it as fuel economy will not be this vehicles best traits. Get your fussy and thrills out of it then sell it and by a more fuel efficient motor, or just except the economy figures or lack of it as you don't get performance and fuel economy unless you buy a Tesla.

I think the s3 is one of best compromises between performance and daily driver, not too many out there that can beat it as a package.

Had an nice leisurely drive from Aberdeen to Loch Morlich and back, decent mpg when sitting with the slow folk
42.9 mpg over 185 Miles.

On my recent drive out to Germany, I was actually averaging 40mpg after 400 miles which I thought was pretty good considering I was cruising between 75-85mph most of the time.

Then I hit the Autobahns...

No it isn't - you're just disagreeing for the sake of it. Pretty much everyone has a fair understanding of what "heavy traffic" is. God only knows why you're acting like agreeing in general terms about such a trivial matter is some kind of impossibly abstract entropic concept.

Or, alternatively, you can not be a gatekeeper and just accept that people are concerned about fuel efficiency for a variety of reasons (especially given that this is a thread about MPG; it boggles the mind why you'd be in here debating it), and the least likely one being "affordability". Most people just find the price of fuel very high and want to get an idea of how much ownership will cost them. This thread helped me tremendously, and others, too, I'm sure.

Making the assumption that anyone who raises a concern about fuel efficiency is doing so because they "can only just afford to buy" an S3 is elitest, extremely snobbish, and says less about what you actually think about the debate, and more about what you think owning an S3 means.

It's a 35k hatchback mate, it's nothing special.

Drove my usual routes the last few days, in the usual traffic, on runs that I've never managed over 20MPG on, and got a healthy 25 both ways (reset). I'm absolutely over the moon. 25MPG was the figure that would make owning the car really worth it, and I'm so happy. It now ticks pretty much every box. I love this car.

What rubbish. "Heavy traffic" is an incredibly abstract term which could just as well describe largely stationary stop/start traffic in an urban environment as it could a busy motorway where everyone is cruising at a steady 40mph.

I have a heavy commute on the roads. I get around 23mpg average as I occasionally get breaks in the traffic to get up to motorway speeds

I can temper that with a recent long distance drive cruising around 60mph for 150 miles and got 38mpg

Is there any truth to people saying the fuel economy increases after a certain amount of time from new, or is that a myth?

I do at least 300 miles per week, exact same journeys and roads every single day, most of it in heavy traffic. (Just to clarify due to the above argument I class heavy traffic as sitting still for very long periods of time in between small amounts of edging forward at 5 mph lol :friendly wink: )
First month of cars life I was getting about 250 miles out of a full tank. I'm on second month now almost 3,000 on the clock and the last two weeks I've managed to get about 310 miles out of a full tank.
Not sure if it's because its loosened up or maybe the traffic wasn't quite as heavy some days?

1) please read my previous post in which I stated I’ve done manual brim to brim checks
2) please read my first line which said I was commenting comparatively and given there are other comments quoting trip computer figures I think my observations are relevant to the debate

Oh for crying out loud. I can't be bothered cross-referencing your posts to work out whether you've also used methods other than the trip computer or how accurate the computer is. In the post to which I replied, you only mentioned the figures were obtained via the trip computer.

Popped over from the A4 board since I have an A3 as a courtesy car at the moment and wanted to see what people were saying about them. Long term average of my S4 over 11k miles is 31 mpg - surprised the S3 isn't that much better to be honest.

Just filled up and calculated i got 37 mpg over the last tank full. This was over a week of medium length journeys (50 mile) at moderate speed (50-60mph). The car computer now estimates 425 miles for this fill up. Not sure this will last.

My last S3 loosened up around 8k miles prior to this fuel economy was pretty dreadful 18-24 mpg, it will average around 30 mpg over the term of ownership
It also gets a bit faster after 8k,my facelift car is slightly worse for economy

This is why doing 20k a year means I can’t afford one yet! :( I’ve got used to my 550-600 miles per tank from my TDI.

What are you driving, how big is the tank?!
I do same sort of mileage and had an A3 TDI before the S3 and I never got anywhere near that many miles out of a tank.

Similar for me I had a TT ultra which would easily return 500 Miles a tank. My S3 hovers around the 400 mark which I’m really happy with.

What I notice more with the S3 is the various maintence costs which I wouldn’t have incurr ed in a FWD manual TT.

I mainly do motorway miles where I’m hitting high 50’s or low 60’s MPG. I’ve a 2.0 TDI which has a Revo stage 1. Although I was still getting these MPG before the map. I always get 550 plus per tank.

What might they be? (as a potential S3 buyer/current A3 TDI owner)

1st oil and inspection service is circa £300 if go to main dealer

You will chew through 4 tyres at a similar rate so unlikely to get away with changing the fronts 1st

I tend to use the higher octane petrol which carries a premium

I don’t know the prices but around 40k miles the Haldex should be serviced

You will go through the breaks a lot quicker especially in the stronic

Ok great thanks for that. Just put 2 new fronts on my A3 after 18K miles and I always use vpower cos I’m a sucker haha, so hopefully not too disimilar there....

No it’s not crazy amounts just something to bear in mind. Insurance can be a tad high but mine is reasonable at £700 with 3 years no claims and 3 points on my license.

I think it also depends on how you drive on that particular day as well. My car is now a year old and has only done 5K. Over those miles it has averaged around 27mpg (going by the trip computer as I can't be ***** calculating it to the nth degree). My journeys are mostly very short trips in urban areas. For example taking my daughter to her gymnastics classes, I can average 24mpg going there and 17-18 coming back (not really sure what the difference is on the two journeys as its the same roads and same traffic. I wonder if anyone can spot the difference :) ). So just because a car only averages 18mpg or whatever I feel the person pressing the pedal has to take some responsibility for the poor economy. If I drive like a c**k I can really see the mpg drop, if I drive it a bit more efficiently the car performs better. When I bought my S3 I went in eyes wide open expecting to get 20mpg but hoped for 25mpg, luckily the car has beaten my expectations. That being said I still think it's **** but but I don't tend to moan about it. :)

Well said, I managed 34mpg the other day which swiftly dropped to 31mpg after a short burst. Overall though it's actually pretty good when driven sensibly. My daily commute takes around 9mins and depending on the time of day I can easily see 31mpg, unless it's nice and the windows are down when it can be as low as 16mpg.

I’d suggest one way is overall uphill and hence the other downhill. My drive to work I get 44 and back I get 50, overall climb or descent must have a bearing I reckon.

I drove my car sensibly on a mix of dual carriageway and b roads. 1.5 hour journey and got over 45mpg on the trip computer. Plentyyyy if driven like its a 2.0tdi.

My apologies, I was just being facetious. The difference is that my daughter is not in the car on the way back so I drive differently. If someone is in the car with me I'm much more measured and I take them in to account and drive smoother, therefore saving fuel. When I'm on my own I like to hear the pops and bangs so mess about more with lower gears and the throttle and surprisingly my fuel economy suffers. So going to gym is 24, I drop her off and coming home it's 18. Going back to pick her up it's 18 and coming back home is 24. The difference in fuel is whether I'm on my own or not. :)
