Is it thinkeble that there will be a A5 3.0TFSI Quattro between the A5 3.2 FSI (265 ps) and the S5 4.2 FSI (354 ps).
The power output of a V6 3.0TFSI will be some where between 300 and 348 hp IMHO.
A future S5 can get Valve-lift added to his V8 with a possible ±44 hp power hike. (producing: ±400ps @ 7400 rpm)

the S5 V8 is bound to be replaced by the 3.0 V6 TT. why? it would improve the weight distribution and handling such that all the criticisms it has in the face of the 335i will go away and once and for all be crowned king of that class. the S5 and 335i coupe are practically the same size. people seem to think the S5 is a 6 series competitor. it isn't.

If that is true then the RS5 will get a atmo V8 4.2 FSI (Valve-Lift ?) engine with 420+ hp.

that we are less likely to be sure about. it would have much more than 420 hp since that is what this last RS4 had. i'd say it'd be in the 500 hp range. probably a twin turbo version of the non high revving engine in the current S4/S5 or a high rev, higher displacement NA V8.

Well, it sure as hell isn't a direct E92 competitor as well!

It's positioned between E92 3 Coupé and BMW 6-series!

The V8 will NOT be replaced by a V6 TT. I can assure you that.

it is a matter of opinion.

with many exceptions manufacturers do not want to go exactly head to head in a market segment, preferring to carve out a subniche within a size/class of car instead.

in the US, the A5 goes against the 328. audi has only one other offering in that line. the S5. anything in between is hard to imagine. one motor makes 265. the other 355. it is well known that this upcoming V6 TT will make about 330. audi has never made an S model that developed just 20 hp more than the model below it. you can argue that the S5 could get another engine, one perhaps making close to 400. then, the RS5 could get a power output of about 500. sure, that is possible. it would be interesting to see. i'll keep my mind open to that one.

265-330-400-500 makes sense.

I think that S5 is natural and direct competitor for the BMW e92 335 i coupe, 6 series is just in ''higher league'' for S5 at this moment...

Also, I think that we aren't going to see 3.0 T in the A5/S5.

There is also still the option of the "Audi Roadjet Quattro" High Rev 300 hp V6 3.2 FSI Valve-Lift engine.
The Euro petrol A5 Line up start with the R4 1.8TFSI 170 hp, then the V6 3.2 FSI 265 hp and the V8 4.2 FSI 354 hp engine.
Putting Valve-Lift to the V6 ± 300 hp and V8 ± 400 hp make room for a engine with a power output between 170 and 300 hp.
The Audi V8 4.2 FSI engine is not the newest engine anymore.
It can get a Valve-Lift upgrade in the near future or get replaced by the new V6 3.0 TFSI.
If the new V6 3.0TFSI engine replace the V8 4.2 we will probably not see a Valve-Lift V6 3.2 FSI engine either.
The only Valve-Lift engine in the Audi line-up is the 210 hp V6 2.8 FSI used in the A6 and A8.

The 265 hp 3.2 already has Valvelift. The 4.2 V8 is too small now. Either Audi puts twin turbos on it (with Valvelift for best fuel economy), or Audi will need a brand new 4.5-5.0 liter V8. Porsche has such a V8, will they share?

i hope audi would put in their future RS4 and RS5 Bi-turbos. i dont like the fact, that BMW (wich were in past against turbocharging) could build more TT engines as Audi.

Gut feeling is that Audi will return to forced induction for their S models at least. Like every manufacturer, they have to weigh up performance vs economy and if a FI engine suits better than a N/A engine then that what will be used.

Sneaky bastards.
I only thought it was a Audi A8 non VL 3.2 V6 version they putted in.
The Roadjet version was a 300 hp @ 7000 rpm version.
Why only 265 hp for the production version. ?

To leave room for improvements on future developments, with it's current power and torque the engine is competitive with the competition, why go further than is required.

Something called "Vorsprung Durch Technik".
Why put "Valve-Lift" in for only 10 hp more and a bid of fuel saving. ?
If they had give it the engine 300 hp then it could compete with the 306 hp bmw 335i coupe.
Now Audi have two engine that could not, the 3.2 V6 FSi have not enough power to compete and the 4.2 V8 FSI have the power but is to haevy.

i hope they wil produce mass new TT engines not just updated older engines to TT. i would like to see completly new TT Engines from audi. i hope they will put they not just in the S models. in the RS models as well :)

It's your opinion that the S5 engine isn't better than the 335i, not everyone will agree with this opinion but I will agree that it is a very impressive engine indeed, but the diesel version is even better.

The 3.2FSi currently is competing with the 330i and not the 335i but then again you already know that. There is a FI version of this engine coming that will compete with the 335i and you will see it soon enough.:hahahehe:

To my mind, Audi will go for smaller FI motors instead of big NA.
This is because of some reasons:
1) more torque for FI motor
2) less weight - better weight distribution, handling and lighter "nose".

Who of you tried new Audi TT 2.0TFSI and 3.2 Quattro - those would agree that handling and weight balance is much better at 2.0TFSI car!
And new Audi TTS - it will be a diamond in the crown!

Audi's valvelift is a somewhat simpler system, but it works at higher RPM. But the 3.2 is a regular engine and doesn't spin to very high RPM so it only makes 265 and not 300.

BTW, Audi's 4.2 V8 is only 11 pounds (5 kg) heavier than the 3.0 twin turbo in the BMW 335i. A tiny difference.

In fact the 4.2 V8 makes 19 more horsepower than the Porsche 3.6 H6 but weighs 14 pounds (7 kg) less.
