Hi guys, I am giving serious consideration to the new S5. The one thing which is stopping me committing is on the test drive the MPG was 21. Whilst I was expecting it to be significantly lower than the 38 quoted that is almost half. It wasnt a test drive where the car was driven hard either although we did sit in traffic for a while.

Any thoughts on what I can realistically expect as an average driver who occasionally puts their foot down? Thanks
 
In my B8.5 S5 I have never achieved higher than a 22MPG average.

Not sure if the new one is meant to be much higher than the model it's just replaced?

I would be lying if I didn't say I was slightly nervous about the running costs when getting my S5, but honestly, after just a week, I couldn't care less! Nearly 10k in and I still love it. It's more than worth it!

I get 25-28 out of my B8.5 S5 depending on how lucky I am with traffic. 28 miles (average 37 minutes) to and from work, mostly constant 50mph A roads and motorway. I get a heck of a lot less round town. Ignore the DIS - I reckon that overreads by 10-20%... I'm with the Doc... to heck with the consumption if there is a stretch I can put my foot down (although I do keep it down on the motorway unless I want to hassle the 1.4 Clio who just won't get out of the fast lane...)
 
PS. The B8.5 has a claimed combined consumption of 35.8. It's probably reasonable to expect 5-10% better consumption than Doc or I get.
 
Thanks for the responses guys. So at best we are looking at 25 i reckon. Just needs some mental adjustment from me haha.
 
I purposefully put my foot down to hear the exhaust burps... and the kick in the back when the DSG (I know the new one has a tiptronic and a wider torque band) drops a gear or two and drops you into the power. Smile inducing... Not had that with any other car.

sairamtim, are you new to performance turbo cars? If so then be aware that the efficiency really does depend on your driving. As others can attest to, if you do a fair amount of leisurely driving where the turbo is off-boost then indeed the long term average fuel consumption can be as high as you suggest. The only way to get Audi's figures will be in economy mode in 8th gear cruising at low revs. But as soon as you start driving enthusiastically, particularly on full power, the fuel will be squirting into those cylinders at a rate which would surprise you. Consumption will quickly get down to single figures. It is difficult not to enjoy the performance of these cars :)
 
Best way to get better economy is to use cruise control whenever possible

I am yes. I have an Alfa Giuletta 1.4 Multi air 170bhp so this is a significant jump in level of car. I currently get 35mpg from that but I am a pretty casual driver. I also know I will drive it quicker as I will love it and the performance.....
Just been doing the company tax maths though and realised I am going to get clobbered if I put this through. My company and first time i've done the company car thing. Decisions decisions.....
 
If it helps I had a B8 S4 and over 27k miles and averaged 19.4mpg (official 30 mpg combined)

Currently have an 8v S3 SB and over 29k miles and have averaged 24.9mpg (official 41mpg combined)

Expecting my new S5 Coupe to be about the same as the S4.

I do a lot of short journeys so that would affect my mpg for sure.
 
Just had a look at Parkers, The combined fuel economy figure for your current car looks to be about 50mpg. The new S5 average consumption figure is 38mpg and it's likely to do a few more mpg than the B8-B8.5 cars being a turbo car rather than supercharged. But it's a big car with a 350bhp engine and full time 4wd so budget on it doing 25 mpg . If it does 23 mpg you won't be much worse off, If it does 27 mpg it's a bonus.
However I wouldn't expect more than 20 mpg in the first few weeks :) .

The petrol is likely to be incidental to the BIK. I drive ~1000 miles a month. I have gone from £150ish/m (A3 2L 184 TDi Quattro which in itself is a sub 7 second car) to about £225ish for the same. Taken in isolation (an extra 50% cost per month in fuel) it is huge. Taken as an extra cost (£75 to be driving an S5 rather than an A3) it is nothing.

If you are concerned about economy, then perhaps S5 isn't the right car for you?

Well although not a direct comparison, I have a 2009 V8 S5, and in my ownership I've averaged 22.6mpg if you work it out correctly.

I use an app to keep tabs as the dash readout can be incorrect. Normally it is a little optimistic.

I think the real difference will come down to if you will use the car mainly on long trips or around town.

Mine around town will probably do about 12mpg if you hit traffic, whereas on a motorway at 70mph, it will sit around 28/30mpg.
 
Thanks for all the responses. I will be ordering the S5 today or Monday. Sod the consumption, all about the pleasure it will bring :)
