B8 S4 to get SC V6?

[s4nicetry]

"Emerging reports suggest that the next Audi S4 will ditch the current model's V8 and open up the gap a little with the top-of-the-line RS4 with a new supercharged V6. Bearing the 3.0T or TFSI badge, the 2010 S4 could benefit from "twin-charging" with the possible inclusion of a turbo in addition to the supercharger.

With a potential unveiling at the LA Auto Show in November, the supercharged S4 is also tipped to feature a Magna-sourced "sport differential" like the ZF unit featured in the BMW X6, bringing the fight to the turbocharged BMW 335i, while the RS4 takes on the M3. While power will likely remain similar to the current 339-hp 4.2-liter V8 and weight only marginally reduced by 100 lbs or less, the purpose in switching to forced induction would be to improve fuel economy while returning comparable performance. The S4 is also expected to be developed outside Quattro GmbH, while the RS4 would be created by the Audi performance division, giving the former a more restrained look compared to the all-out bulging bodywork of the latter. The forced-induction V6 is also tipped to replace the 3.2-liter V6 in the base Audi A6 Quattro."

Thats good to hear... basically it is going to be lighter-weight, better fuel economy, and most important better tuning capabilities.

[Overboostin]

blah, turbo or bust.

[Obi_agent]

+1......TT is the way to go.....Supercharged+turbo is a waste.

Anyway, I wouldn't mind a SC/T V6 until or unless it has a turbo. You can still up the turbo boost

[AAAA]

i think both may turn out to be a tuning nightmare. and/or its going to take a long time to get even software out.

My plans were to stop modding my car and wait to buy a TT s4. in the words of Dave Chapelle "audi is fucking up."

A supercharger and turbo would be a great setup, IF they can figure out how to house both chargers, and have them share the plumbing for the intercooler/s.
Granted, a SC and TC would be great as you can tune for the nice off idle low rpm torque, and then bring the turbo on during mid-rpm, then take advantage of a turbo's greater potential for high rpm power building.
It would make for an interesting setup. However, if you use a small lightweight variable vane turbo for low rpm torque coupled with a larger variable vane turbo for mid to high rpm, you'd reduce the drag an SC has, and you could more easily control a twin turbo setup to share the IC and intake plumbing. Both would be unique, but a small + large turbo with variable vane tech would be WAY COOL. Porsche could easily provide assistance with the variable vane technology, and it's part of VW group, thus sourcing the turbo's would lend to lower cost from economy of scale.

Read the second paragraph from the bottom, where it says :
"The new S4 will be lighter as well, as the B9 A4 body"
Am i missing something or that's just a mistake???

they were probably thinking of the 09 b8 and just accidentally merged the 2.

I don't understand, if the new V6 3.0TFSI engine is introduced at the 29th Vienna Motor Symposium, why are there no pictures or tech info of it.
Have Audi only mentioned the engine for the future or have they put out a press release with pictures and tech info.
Normaly this kind of info (pictures & tech info) is public within houres.

Maybe they also printed 'supercharged' instead of 'turbocharged' by mistake

Maybe a couple in the 3.2 V6 A4.
300hp/320lb ft. I'll take the B8 A4 over the 335i.

Audi, if not, then I may have to go back to BMW. You guys are falling behind. I've never been a slow, steady, stay the course kinda guy.

[AAAA]

the b8 will have 211hp/258lb/ft. i'd say that will benefit much more than the b7 w/ just chip and bolt ons. 48lb/ft is a large gain! i think i will be driving the sc s4 to determine whether i'm getting it or not. otherwise, i may go 335i or 135i

[loustylez]

supercharged.

Why do they call it a 3.0T if it lacks a turbo?

[JCleary]

The benefits of compound chargers are many...

For one, if the first compressor makes 10psi, and the second makes 10psi, the net effect is 20psi at 1/2 the temperature of one compressor making 20psi. I'm throwing out loose figures, but you get the idea. The turbo is mounted just like any other turbo, and the supercharger is mounted direct to the head. No cooling for the supercharged air. Diesels have been using this technology for 30+ years. The only reason it hasn't been applied to gas is because it hasn't been a financially sound investment before. Now with ever-rising fuel costs, the cost/benefit ratio is starting to make sense.

Whether it's compound turbos (like a lot of aftermarket companies make for Dodge Cummins diesels) or a turbo/supercharger setup seen on Detroit Diesels, the benefit is there. On my '03 Dodge, 60 lbs of boost would have a 300°+ IAT with a single 66mm turbo. If I used set of compounds (more commonly referred to as twins) to make the same 60 lbs. of boost, the IAT would be around 200°. Both turbos last longer because they both are operating at 1/2 the load, as each is only producing 30psi.

Another benefit is you can use a super small secondary compressor to spool instantly (or a supercharger) and a much larger primary to give you boost on the big end...

Good stuff. I hope to see more people than FoMoCo putting this technology to market!

[AAAA]

i think the new articles clearly state it will be supercharged only, with just one of them

That car doesn't look much like an "S4". It looks very much like an A4 with dual quad-tip exhaust.
I'm still hoping that Audi will get smart and offer that "detuned" 290hp version for the V6 A4 variant, calling it an "S" performance package, to compete with the 335i, IS350 and the like.

Supercharged V6 A4 priced within 335i IS350?
I'll take it.

the detuned version will go to the new facelifted a6, so no such luck to put it in the a4

[raulg_usa]

Will the current V6 3.2L 265hp stay in the A4? Still?

Perhaps the S4 will get the supercharged V6 while the B8 RS4 (whenever it comes out) will get the TT V6 motor. Look at the B5 S4 vs. the B5 RS4. Smaller turbos on the B5 S4 among other things (widebody, etc), but essentially the same car with the same heart. Maybe the B8 S4 getting the supercharger is almost saying it is a "smaller boosted variant" of the coming B8 RS4. It's a hell of a shot in the dark, but I wouldn't dismiss it..

well it got bumped to 265, will be fsi and have valvelift

I'd have to hear it from Audi's mouth first before I call it confirmed, I certainly hope the media has been getting false info on the subject and Audi is just keeping tight lipped, I'd rather have a SC'ed V6 over the V8 unit but man I was really hoping for a TT engine it just seemed to make more sense for Audi experience on the subject, even the twin-charged powerplant talked about earlier would be very cool. Come on Audi surprise us god damn it!!!

[Cargo8]

^^ teh engine was revealed at the vienna show/engine revealing/watever. as in... revealed by audi. I mean it's not confirmed explicitly: B8 S4 this supercharged engine that we just debuted, but... i mean, where else?? Didnt see them reveal a brand new TT engine! :)

The information I got says that Audi is considering dropping the V6 altogether in the A4, they will be all 2.0t with a power/torque increase, as the V6 is not the big seller. It would not surprise me, it would lower costs not having two engines. I'm not sure when this is scheduled to happen.

[Iceman]

The 265hp 3.2 V6 FSI engine will most likely be replaced with the same 290hp 3.0 V6 SC engine as the one that will be availeble in the facelift A6.
The S4 will get the high performance version of it with ± 350hp.

I know. I was just "hoping" that Audi would get smart.
Just because it's going into the new facelifted A6 doesn't mean there is no such luck. The A6 has shared engines with the higher powered A4 in the past.

I haven't heard that at all. However, it would be just fine if the V6 A4 option does become the "S4" with a price adjustment to keep it in line with BMW's 335i, MB's C350, and Lexus IS350.

But, I haven't heard that Audi is dropping the V6 A4. If anything the B8 A4 V6 is getting a revised 3.2 V6FSI with variable vale timing and some tuning adjustments to up the hp and torque as well as get same or better MPG.
So, I don't see them dropping the V6 option. It's the better selling model for the "near luxury" buyer who finds a 4 cylinder engine somewhat "small" for this category. Yes, enthusiasts know the 2.0T and it's potential, but most buyers of these types of cars don't "tune" or buy ECU software.

That is what I have been saying, hoping for, and promoting.

[A4_cabrio]

I hope they keep the V6 in the lineup. The 2.0T engine is too noisy and unrefined. Yes, it has nice power and torque but that something that matters to us, people that would tune the turbo. However, it wont compare to the smoothness and quietness of the V6.
Test drive the A5 and you'll understand. I hope they refine the 2.0T and make it a lot less noisier.

[littleredwagen]

Audi will probably not gonna drop the 3.2 V6 option from the A4, becuase it does sell and they make the most money from it, since it is an Audi exclusive engine. Until Audi Makes a formal press release saying it(S4) will have a supercharged V6, I would not count on Car and Driver's statement. It just doesn't make sense to from a business point of view to even build the engine given the economic climate and the little saving in overall MPG, and of course US federalization.

I don't know if US is the same, but a local ABS up here in Canada posted the sales stats for the first 4 months in Canada, and the 3.2 isn't selling well like you thought. In fact the volume is about 13:1 in favor of the 2.0T.

As for the 3.0 SC V6, the engine has been announced in the Vienna Motor Symposium a couple of weeks ago. It's slated to go into the S4 at ~350hp & the A6 in detuned ~290hp.

[gods_kitchen]

I guess I won't be getting a S4 anymore
