Supercharger - Audi Technology Portal

About time they updated it to show the current one!
 
Really? Surprised at that given the advances they've made to get it Euro 6 compliant. Where did you see that?

This is old information and out of date.

Audi's current head of R&D, Dr Ulrich Hackenberg has clearly stated in an interview with this months EVO magazine the following:

  • Audi will stick with large V-configuration petrol engines because they're premium.
  • The new petrol V's will be turbocharged, a single turbo for the regular range and twin-turbos for the performance variants.
  • The supercharged V6 in the S4 is history - the next S4 will have an all-new twin-turbo V6
  • The next RS4 will lose its V8 for a highly tuned version of the new twin-turbo v6 possibly with electric turbos.
  • The twin-turbo 3-litre TDi V6 engine fits in the new A4, but the business case is not currently viable for an 'S4D'
He mention a load more other stuff but these are the items pertaining to the S4 and RS4

I have tried to speak to my friends in the Audi powertrain department and even though they are not saying much they did confirm the the EVO interview is pretty accurate.

That said, I am very familiar with the automotive design process having spent many years in it and things change and multiple streams of design are worked on at any one time. This means a change of direction can be made at any point. Remember the 1st S5's, they got the old S4 V8 (340bhp) because the V6T wasn't ready when the chassis was designed, it later got changed for the supercharged unit.

You may see the 1st B9 S4 with the V6T engine until the twin-turbo is absolutely spot on then they'll swap it out,

Hmm. Twin turbo V6 sounds interesting but one thing I love about the supercharged V6 vs the turbo'd 4 pots I've had before is the zero lag and instant grunt from standstill. I guess as long as the two turbo set up addresses that then it could be a belter.

Interesting. I have to say the thing that attracted me to my car is the fact that it is supercharged and not turbocharged. Until Audi have electric turbocharged engines in production I'm not too interested in going back to lag city. It seems strange that according to Dr Hackenberg electric turbos are only a 'possibility' for the RS4, especially as I understood that Audi wants a quicker launch for the B9 RS in comparison to previous platforms. It can't be good for RS buyers knowing that the equivalent S model can be easily tuned to the same or even more power. In general (unless someone demonstrates me to be wrong) this has not happened except in the case of the B8. Unless Audi do use electric turbos on the RS4 then it'll be the same as for the B5 - the only way to maintain a power difference from the S4 will be bigger turbos, and so more lag, and maybe changed engine internals, all adding cost.
 
Dr Hackenberg di discuss electric turbos and has stated the following:

  • Electric turbochargers will make their debut on diesel engines, initially in the SQ7 and next A8 V8 TDI models

So this will mean that electric turbo charges are not exclusive to the RS models.
 
Even more reasons to be cheerful about having bought a B8 S4.

Thanks for the up to date info @GeoffDunk :thumbs up:
I've added your post to the relevant thread in the B9 section

Personally, my current S4 will be my last A4 shaped Audi TBH
I don't like the look or interior of the B9 TBH, whether I change my mind I suppose only time will tell ...
I wouldn't leave the Audi brand at change time, but I could see my self in a S3 saloon or sportback ;)

Thanks for sharing and quoting me @Bristle Hound , I will work on further inside info and publish what I can when it comes. There are obviously things I can't publish and I have expressly asked my friends not to chat about things I can't talk about for obvious reasons then I can't say something I shouldn't. The automotive industry is very secretive and I have spent 14 years in it now (blimey, that long, I need to retire) and I respect the need for secrecy and pride myself in abiding by that. High-end power-train and F1 are my regular areas and as you can imagine there is a lot of state of the art technology within both.

As for the new A4, maybe that will grow on you. I drove a new X5M today with a view of replacing the wife's X5, although she'll be getting a 40d or maybe a 50d not the M and I see the similarities, but I like it. The new Q7 is now of her list as, wait for it..........................the cup holders are too small!!!!!!!!!

It makes sense. The tech that was described for the TT concept includes recuperation so the focus is as much on efficiency as driveability. The fact that the first two cars to have it are big suggests that the hardware is too and maybe it'll take time to make it smaller. But I still remain baffled why Audi want to drop the award-winning 3.0 TFSI engine if its just for a V6 turbo, unless the capacity is much higher like the GT-R. But that doesn't make sense since Audi already have the 4.0 V8 turbo.

Anyway as per Jeff, I'm glad I bought a B8 as none of this news is making me feel that I'll regret it later. I remember when I got my B5 S4 at the end of its run and dealers were telling me to wait for the B6 S4 instead. Not only did I think that it looked like a beached whale but the V8 was a disappointment (compared to a tuned B5).
 
The turbo power-plants will have better emissions and better fuel efficiency. It also means one base for possibly 3 models in the A4 range plus other models in the Audi range keeping costs down. At the moment the V6T engine is essentially only used in 2 models which is not economically efficient.

BMW have shown the way in this design model, take their 2ltr and 3 ltr diesels, these base engines are used in every model it just depends on the level of tune and amount of ancillaries, i.e. turbochargers. its a very good economic model.

The concept of 'adaptable platform' was coined some years ago, the VAG group have exploited this in the best possible way, multiple brands using the same base platform (chassis). Couple that concept with BMW multiple engine style model and you have a very efficient all round concept.

Someone thinks the supercharged S4 / S5 engine is better than the 4.2 V8 ... :whistle2:

I didn't say one was better than the other, I just know I prefer 4.2L v8's with 450PS rather than V6T's with 333PS.

A V6 is an inherently unbalanced engine, V8 is better, V12 is the best, its all down to 2nd and 3rd moments of vibration etc.

I've owned 4 V8's and love them, they are a dying breed.

@GeoffDunk - I know you didn't. Apologies if that post came across that way Geoff

It was only a 'tongue in cheek' one as I knew you would be along, having an RS4 ;)

If I had the pennies, I know which one I would have and it wouldn't be the Supercharged one ...

True - I guess I overlooked the factor that turbochargers are more efficient than superchargers. Anyway was Dr Hackenberg's comment only about the S4? Audi USA have the 3.0 TFSI for the S5, A6, A7, SQ5 and Q7, and I believe that it is still used in the Porsche hybrids. After the major redevelopment required for the CREC version and the fact that the US, being Audi's biggest market, like supercharged engines, I still think it would be crazy to completely drop it.

Dr Hackenberg's comment was "the supercharged V6 fitted to the S4 is history" so I assume that engine is history. The same principle applies in my previous comment, better to have as many common items as possible across the range to keep both production and developments costs down.
