4.2-litre V8 FSI?

[Imperial]

so uh, as a relative V8 S4 noob, I was wondering if anyone knew if the S4's V8 engines will be or are offered with FSI technology...

anyone have any ideas?

[Redundant]

From some random posts in 'the other forum' if I remember correctly; they were predicting that they were going to come out with a V8 FSI, but I believe it was all speculation. I'm not sure if they are or not anyone else care to elaborate?

[foofighter]

i'm sure FSI will be implemented in all the Audi/VW line it's a great technology and was actually developed on the V8 prototype Le Mans car. It's just a matter of time...imagine more hp and better gas mileage [:D]

[Silvant]

supposedly that is supposed to be the heart of the
new rs4... on top of a few turbos...

[astris]

Makes sense since they use the FSI technology on their V8 turboed race cars. Can't wait to see. Maybe they will up the power another 30 horses like the A4. [:D]

[Imperial]

so will the B7 S4 come with an FSI V8?

[foofighter]

i would go out on a limb and say yes as i stated earlier FSI will most likely replace all the 5 valve is old news [:(]

Call me stupid......but what exactly is FSI??

World-leading innovation isn’t new ground for Audi, and Vorsprung durch Technik - progress through technology - is more than just a slogan to the German manufacturer, it’s a way of life. In fact clever use of leading-edge technology, from aluminium construction to the world famous quattro all-wheel drive system, is right at the heart of the Audi design philosophy. And not just technology for the sake of technology, but technology for the real, everyday benefit of real, everyday drivers. Or in the case of FSI, a combination of benefits other manufacturers can still only dream about.

FSI is Audi’s ground-breaking answer to what has long been a holy grail for every motor manufacturer in the world - more power with less fuel consumption. Many have searched for the answer, some have even had tantalising glimpses of the goal, but until now none has achieved the seemingly impossible. Until now. Because with FSI, Audi have finally found the grail, with a new technology to lead the entire industry.

But this isn’t technology for the privileged few, this is technology for the widest possible audience, because although FSI was developed and proven through the highest levels of world motor sport, Audi have deliberately brought it to the production market first of all in the company’s highest volume models - first the A2, and now the A4.
Audi describe FSI as ‘the most important innovation in petrol engine construction for 25 years, since indirect injection began to take over from carburettor technology’.
It's a winner: Audi proved its FSI technology in the company's all-conquering Le Mans racing car, the RS8.


So while other manufacturers have made evolutionary progress with their petrol engine designs, with FSI Audi have made the revolutionary breakthrough that puts them way ahead of the field. Because in a world governed by compromises, Audi have taken compromise out of the equation. In a nutshell, FSI finally enables Audi’s engineers to offer increased power from any of their petrol-engined cars, but with the unique efficiency to make them more economical, more environmentally friendly - and even better to drive.
What’s more, this isn’t technology in development, this is technology that is already proven in arguably the toughest test of all, the Le Mans 24-hour race, where for the past two years FSI has helped Audi complete a unique hat-trick of back-to-back wins, in each case with the same team of three drivers, and in each case simply steamrollering all opposition. And what works for the world’s most famous and demanding endurance race will also work for every Audi FSI driver on every journey.


A2 FSI: known for its innovative approach to car engineering, Audi has fitted the new engine to its mould-breaking supermini.
Like all the best answers to complex problems, in FSI Audi’s solution is actually outstandingly simple, and therefore utterly reliable and readily accessible. Where other designs still accept the age-old compromise of a fuel delivery system which has to bridge the gap between low-speed pottering and high-speed power, FSI rewrites the rules. Deep in the engine, FSI genuinely offers the best of both worlds - optimum performance and optimum efficiency under both part-load and full-load conditions.

At its simplest it makes use of the well-established science that makes a diesel engine more economical than a petrol engine, but for the first time ever, combining those with the equally important advantages of the very best of petrol engines - quietness, refinement and power. So FSI combines very high pressure ‘common rail’ injection with ‘direct’ injection, (straight into the combustion chamber rather than into the inlet ports). And it combines that with a clever variable inlet system and specially shaped combustion chambers which create the optimum fuel mixture for every load condition. That also allows an unusually high compression ratio, which improves efficiency and reduces emissions, while producing more power and better throttle responses - at all engine speeds.

Fundamentally, at part load, where the combustion process only needs a ‘stratified’ charge of fuel in the area around the sparking plug, FSI (using a ‘tumble-flap’ in the air-inlet manifold) delivers exactly that, and no more - so no waste. And because airflow into the engine isn’t restricted during part-load operation, combustion is more efficient, and less heat is wastefully lost through the cylinder walls. But at full load (when the ‘tumble-flap’ opens and the inlet path is shortened), FSI fills the combustion chamber with a ‘homogenous’ fuel charge. That is, precisely the right amount of fuel, injected at the optimum moment, and with an injection pressure 25 times higher than with conventional petrol injection - which creates extremely fine fuel atomisation and very good internal cooling of the combustion chambers. And that in turn is what allows those high compression ratios, for greater efficiency. The FSI engine's "tumbleflap" (arrowed) controls the way fuel and air enter its cylinders. In "stratified" mode the minimum amount of fuel is delivered into the top of the cylinder.


In motor sport, the benefits are easy to see, especially in endurance racing where fewer fuel stops and bombproof reliability are the icing on the cake of maximum power and performance. And that has paid off to the extent that the classic Le Mans 24-hour trophy now has a permanent home in Audi’s trophy cupboard after those three dominant wins in three years - the last two using FSI. But now it’s the ‘ordinary’ Audi customer who reaps the benefit of motor racing improving the breed.
Eventually, FSI could be available across the Audi range, but that commitment to offering cutting-edge technology to the widest audience saw it introduced first in the A2, and now in the A4, with all the benefits described above.
In "homogenenous" (or normal) mode, the tumbleflap opens wide, allowing fuel vapour to fill the whole cylinder for efficient high performance.

More information from Audi


So the four-valve-per-cylinder FSI version of the 2.0-litre A4 four-cylinder engine (which is also the lightest in its class) produces 150bhp compared with the 130bhp of the five-valve 2.0-litre A4 engine; it develops 147lbft of torque compared with 144, with a wide, almost completely flat spread. That improves top speed from 132 to 136mph, and trims 0-62mph acceleration from 9.9 to 9.6 seconds; at the same time it reduces fuel consumption from 35.8 to 39.8mpg* - a better than ten per cent improvement overall compared with its own efficient stablemate.

As well as a 10% improvement in fuel economy, the Audi A4 2.0 FSI offers an increase in power from 130bhp to 150bhp and higher torque.
Looked at another way, that means an increase in maximum range from around 550 miles to 615 miles - or potentially an extra 65 miles between fill-ups. External exhaust gas recirculation (recycling up to 30 per cent of exhaust gas back to the combustion chambers) plus a very sophisticated emission control system also contribute to another FSI advantage - CO2 output down from 190 to 170g/km. And all without adding unneccessary complexity, without servicing penalties, and with exactly the same long-term reliability as any Audi.

Independent figures also suggest the FSI engine can be as much as 15 per cent more economical than rival engines with similar power and conventional injection.
But impressive as all that is, it’s only the tip of the iceberg. What FSI actually delivers is more power and torque across the whole speed range, so looked at another way, it offers the same power at lower revs (say in traffic or around town), for a more relaxed drive as well as a more economical one. In fact the biggest fuel savings of all are delivered at the lowest loads, in other words in everyday traffic conditions. And with more power at the top end, and sharper responses everywhere, FSI combines better economy with even more sporty performance for the enthusiastic Audi driver. More enjoyment, let’s say, for less consumption - which also, of course, equates to lower emissions and a lower tax liability.


And if all this seems too good to be true, don’t be deceived. It’s real, and it’s in Audi showrooms now. FSI technology is accessible technology.
* Fuel consumption notes
The official fuel consumption figures in mpg (l/100km in brackets) are: Urban 28.5 (9.9), Extra Urban 52.3 (5.4), Combined 39.7 (7.1). CO2 emissions 170g/km. The maximum benefit from FSI technology can be achieved by using a low sulphur fuel, ie one containing less than 10 ppm sulphur.

Gotcha!! thanx for the info

hahaha, indeed my friend, indeeeed....

[:D]

[gecco]

Btw, when were into the engine talk here. Is there any new info out on the new RS-line ?

I've heard that the new RS4 is having a nice biturbo V10 at 500+HP in it. And the RS6 will have the same engine, but rumored at 600-700HP. And the RS3 will come with a 3.2L FSI engine, not sure about the specs on that, but surley not a bad one.

Anyway, rumors going around here in the closer-to-germany-sections of the world...

[foofighter]

the S cars will have the v10's the RS4 i feel would/should get the current RS6 V8 BiTurbo the RS6 should then get the V10 BiTurbo the RS3...hmm...3.2L V6 BiTurbo? All speculation at this point

[TurboTony]

tell germans to win on the most engineering oriented sport like formula 1 and then will talk...

Tony

[gecco]

Hmm, why is Formula 1 the most engineering oriented sport ?

I have not yet seen one good engineered car from Renault, but hey, check out the F1 teams, damn right their name is there. So im not so sure if i agree with you on that one.

I would more like to call Le Mans 24 the most engineering oriented sport (but im not saying it is). In F1 the teams run like a couple of hours on the same engine and other car parts. At least in Le Mans you need to make a good enough engine (and car in general) that could last a 24 hour stress test. And yeah, last time i checked that one, german car manufatures were all over the place.

Im not saying Ferrari is'nt a great car manufacturer, but im not saying their the best just because they win the F1 all the time.

Lets not get all excited about the 20.000rpm engines, and up to 400km/h speeds. At least i want to drive to work without changing my engine for my return home. . .

[TurboTony]

Let me explain something to you, technology in formula 1 is incredible, those engines are v10 s ok, but the size of them is 2.997 cc...yes its a 3.0...non turbo or supercharger, and they put out 900hp...and they up to 19,500 rpms..everything around the car is the latest in the every field, suspension, braking, antyhing...name me a car that has so much technology and i will agree with you.
And plus with the new regulation a engine has to run thursday, friday, saturday and sunday, and they have to keep the same fuel from saturday to sunday.
I ve seen those cars in person, and believe me theres nothing like it.
Formula one is all about tecnology.
(please if someone quotes me dont even think about nascar, im disgusted by that "sport").
Thank you

BMW-Williams had a good stint in F1 for a while, they've just been out of the loop for a while last I heard. I dunno, I'm not as up-to-date with Formula 1 as I'd like to be.


This thred is getting off topic, though...

[TurboTony]

this should help.....http://f1.racing-live.com/en/season/standings/index2004.shtml

Imperial you know you want one, only 499 a month hahaha!!!

that's cos we are smart!

haha..

But the new A6 has FSI .

[foofighter]

indeed it does! [cool]
