So after much contemplation I have decided the Audi S5 is to be my next car.
So the question is which version.
I love the sound of the v8 in the pre2012 coupe, so was initially considering that, then I noticed the convertibles are cheaper but came with the v6 only.
So firstly, v8 or v6? Anyone bought the v6 and wished they got the v8?
Is the v6 tuneful at all at revs?
Then the next question, did the facelift give much more to the S5 and worth the extra cash?
On the surface it looks a little sharper, but was there much under the skin improvements?
So basically I'm thinking a 2010-2012 v8 coupe , a 2010-2012 v6 convertible, or a 2013ish convertible .
I'm based in the US where petrol, or gas, is usd2.5 a gallon, so fuel economy is not my concern:-)

Plus any other helpful buying tips welcome!

Clearly 2?

One asking about runnning costs, this other one trying to ascertain which model is best and for what reasons

Not sure which bit is confusing for you but hopefully thats clarified the matter.

I had the V8 for a few months last year but think I'd have probably preferred the V6! Found the running costs a little excessive and its not the most responsive engine around town given it's a big N/A. I'm now driving a BMW M135i which I much prefer and find usable as a daily.

Having said that, the V6 seems to have issues with it's S-Tronic gearbox whereas the Auto fitted with the V8 seems pretty solid.

S-Tronic box from 10 on is fine as long as 38k oil changes are observed.

I do like the noise they make although standard exhaust is very quiet. Easily fixed with a Milltek (get yourself onto Youtube).

Facelift cars have better steering, sound, and infotainment systems.

The V8 is slightly more powerful and a little bit quick, and it has the plus point of being a V8!

Thanks for the replies , I was looking at either car to be a '10 model as I like the led rear lights.
I just wish they had made the convertible with a V8!
I think at the end of the day I will go with the Best Buy , convertible , v8 coupe or facelift model, with a slight lean into the the convertible as I'm also considering buying a California car and doing an epic road trip back to NYC:-)

If power/performance is a priority then the V6 is more tuneable for not much cost. An extra 100 - 150hp appears to be a relatively straightforward/cheap mod.

That might tip the balance to the V6?

2010?

My FiL had to have his replaced on a 2013 car. Cooking 2.0TDi model I think...not sure if they're the same box?

I'm starting to contemplate changing my B7 RS4 for a B8 RS4, and one of the slight reservations I have is gearbox longevity. Think my FiL was quoted 8k (dealer made some contribution but not much).

In real world I suspect the V6 Supercharged will be better.
Also, the V8s are slow. I beat one in my diesel. They all suffer from carbon build up and barely make 300bhp (Rs4 B7 goes from 420bhp to 320!!!!!).

The V6 sounds nice (not as nice as a V8 but not bad at all), a very tunable, pretty reliable. My friend has one which is Stage 2, 450ish BHP. It goes very, very well and get gets 35mpg on the motorway.

I think you may need to stand to be heard more clearly smile

The V8s need to be rev'd. Diesels very much do not. Perhaps Ayrton wasn't trying whilst Pastor was all the way to 4k in his diesel...? wink

FWIW when taken onto a rolling road my then 8yr old RS4 had no coke build up and was pretty much on the money power wise.

It was my friends S5. He was trying. We had an ice cream on it.

RS4 power loss:

I'm sure you are aware on rs246 it's a very big issue.
This guys Dynod 354 before clean. After carbon clean it was back to around 415. He did a very interesting test. Standard - after one of those hydrogen clean things - after a proper clean.
I have myself seen one at Surrey Rolling Road (charlie is on here somewhere) doing 330bhp. They never make their figures.

What "diesel" do you have?

It's heavily tuned. So not really a fair comparison.

But anyway, my point is that the V8 S4/S5 are not very good compared to their forced induction relatives.

And they can also suffer from carbon build up which effects the NA engines a lot more than it does on the forced induction engine.

The only benefit to getting a V8 one is initial purchase price is a bit lower and the noise.
But the supercharged one is more economical, faster more of the time as standard, can easily and cheaply be tuned for mega BHP.

At the end of the day the OP has to buy and live with it so he/she/it needs to decide for themselves.

I'm genuinely interested what car you have? How powerful is it compared to the standard V8 S5?

I have a Scirocco TDI with the common rail 2.0 engine.
I have a thread on it here

It last dynoed at 255bhp (flat from 2800rpm due to crap cyl head) and 435ft lb.

I vaguely remember you getting similar or maybe slightly better times than me in that at Santa Pod on the PH SS last year (I was in my S5 V8).
