TTS Supercharger development for RS4

[sakimano]

The thing is for me there's not a car at the moment that ticks all the boxes in terms of pace, practicality, style, noise etc.
Any new car would be a compromise and a <beep> load of depreciation.
The only one that is interesting to me would be the new v8 twin turbos but no confirmation that then new RS4 is getting these. If it ends up with a RS5 lump then no point changing really and might as well throw cash at the RS4.

I think it's a safe bet that the new RS4, if it's ever released, will get the RS5 setup. Here's why

1. that's a quattro engine, while the 4.0T is an Audi engine
2. the RS5 is 'above' the RS4 in Audi's mind, just as the S5 is 'above' the S4. Fitting the RS4 with a bigger power/bigger torque engine would be absurd.
3. 4.0T getting shoehorned into the B8 chassis might be tough...why would they want to go through the R&D for a limited production, Europe/ROW only Avant?

It makes a ton of sense for the RS4 to get the RS5 engine. I'd be shocked if it didn't. It also makes absolute sense to keep a B7 RS4...although Audi seems to have found a way to limit carbon buildup, so that's really the only big 'plus' of the updated 4.2 FSI quattro GMBH engine. To that end, have we seen inside an RS5 manifold yet after 15,000+ miles?

Don't think anyone has driven an RS5 15k miles yet, they've all sold them back after the disappointment of ownership.....

How true... just read Evo and every month you can see how disappointed they are with their RS5.

[sakimano]

...but EVO doesn't love BMW or anything...

Anyway, I can't take EVO seriously anymore. It feels like talking to the B5 S4 forums. "give me turbos or give me death'

It's most evident what has gone on at EVO of late when you read their test of the RS5. They complain it doesn't feel fast enough. They say it barely pulls on the S4 Avant (3.0 SC V6) camera car (but don't talk about how the S4 got a good head start and thus an MPH advantage...which if you've ever raced anyone, you'd know is huge). Anyway, why does everyone else test the RS5 with numbers that pound the B8 S4...everyone but EVO?

The final nail in the EVO credibility coffin is when the writer of this article (published in April 2010 (18 months after the launch of the B8 S4 and it's 3.0 supercharged V6 engine) references the B8 S4 as 'turbocharged' 2 different times in the article. Sounds like he needs to do a little homework. Clearly he hasn't driven/ridden in a B8 S4 (even though at the end of the article he declares that he'd rather have one)...or he'd know the squealing noise under the hood indicates there's a supercharger present. I mean does he even know what a roots blower is? Maybe he thought there was a pig trapped under the hood?

It sounds like the writer drives a 1.6 turbocharged hatchback, and is 'used with' a turbo boost hit that is absent from a 60,000 pound normally aspirated RS5...thus it's not fast.

The one thing going for the 4.0l v8 is the significant reduction in co2.

The new v8 is very compact - be surprised if it didn't fit in a b8

EVO aren't the only people that don't rate the RS5, I've yet to read any article anywhere that rates the RS5 - which doesn't surprise me as Audi lost the ride & handling team that developed the B7 RS4, so now they're back to their bad old ways.

Let's hope they poach em back before the next Rs4 is too far developed,if they don't these supercharger threads and developments will become even more relevant to me

1. no longer relevant for the RS marque .... the ethos has changed

2. The S5 has the same engine in all variants and power as the S4 ... yes the RS 5 is "above" the RS 4, but it has 450PS ... what do you think the RS 4 will have ??? It's likely to be 450PS also, but 4.0T

3. 4.0T V8 will fit no problem. Also the RS 4 is easily the highest volume and thus most profitable RS variant and the halo of the RS marque, you cannot simply ignore these customers else they all end up in M3's or C63's

The overwhelming driver for the 4.0T is emissions and MPG



and also, the RS 5 is easily faster than the RS 4 due to the brilliant S-Tronic, and dual air intake and extra 250rpm .... its not as great handling due to the extra weight .... but underestimate it at your peril .... I had one for a wkend, and its easily everything the RS 4 does on public roads

[lengster1]

But it should be better and simply matching a 4 year older car isn't enough

Except carry more than two people

+1

Not that im really thinking of changing her, but I do like the idea of putting more cash into the RS4 then PX against another lesser motor in a few years

Why not?

very true...it's definitely not as good as the M3 for razors edge handling, and road feel, however it's only marginally slower than the updated M3 (if at all) and is a stunner to look at. I'd take the RS5 ten times out of ten living where I do (we get 3 months of snow)...and I'd probably be split on the choice if I lived somewhere warm. Most of the reviews place the RS5 behind the M3 and C63, but do so with a very cautionary comment to not let that make you think the RS5 isn't excellent. EVO on the other hand would have you believe a Fiesta is a better choice.

1. can you please explain that. I don't see this. Of the RS3, RS5, RS6, RS4, TTRS of recent years, can you name any that shared an Audi A/S engine?
2. I don't understand...are you agreeing with me? I said putting the twin turbocharged V8 making 80 more torque and just about as much hp (in S6/7 tune) would slaughter the RS5, which contradicts Audi's direct assertion (and pricing to echo it) that the 5 is 'above' the 4. A 4.0T RS4 would slot the RS4 above the RS5 in terms of performance by an alarming degree, as well as posted engine output. I said the RS4 would not get that engine...it would get the 4.2 FSI setup in the RS5, just in case you missed it.
3. That's great that it might fit. Will be interesting to see someone swap that engine in one day. As for the RS4 being the 'halo' of the RS marque, I think you're a little off on that assessment. C6 RS6 owners with their twin turbo V10 might have something to say about that.

It's not the actual halo more the de facto halo.
When you talk rs the car that spring to mind first is the rs4. Same goes for BMW with respect to the m3.

New rs will be forced induction - emission regs coupled with the volume Audi would want to sell means that theres not much choice.

I don't see the rs 5 as above the 4 but more compliments it. Afterall it's just an rs4 coupe...

what volume do audi 'want to sell'? These cars aren't about volume. Heck we've only had 3 (ever) on this side of the pond even though the US is third or 4th biggest market for Audi. The C5 RS6, the B7 RS4 and now the TTRS. We are getting the RS5 as a 2013 (refreshed) model, but I can bet we won't see this RS4 avant.

Audi don't even offer the S4 avant here...or the A6 avant. Americans want SUVs annoyingly, so that screws our Avant-lust. I'd love a B7 RS4 avant.
