Tuned A6 vs Stock S6. Who wins?

[88BlackZ-51]

Curious if anyone has personal experience with this question. Let's use 2014 as the model year...

Would a tuned (single pulley and ZF8 tune) A6 be able to hold its own with a stock S6?

I understand that these S6's being tuned are monsters and a tuned A6 wouldn't be able to keep up.

From the reading that I have done it seems that the S6 is 300 pounds more then the A6.

My A6 currently has warranty still so I haven't tuned it. I was originally going to purchase the S6 but I didn't see the value being double the cost.

If a tuned/pullied A6 can hold its own with a stock S6 id be a happy camper as the S6 in stock form is no slouch.


Take care.

Can't speak for 1/4 mile - but bone stock S6 around 375hp / 365trq
my APR stage II dual pulley runs around 390hp / 380trq
Stage I single pulley I've witnessed put down around 365hp/345trq

This is all on the same mustang dyno. Even mildly tuned S6 will be quicker.

[97B518TQM]

I went from a fairly well built and dyno-tuned single pulley stage 2 S4 to an S6 so I have first hand experience with this comparison, at least between the two engines. Keep in mind the S4 is probably a little lighter than the A6 due to size. The S6 stock felt like it would very easily keep up with my modified S4, if not even take the lead on the highway. Off the line my S4 was able to get down to 3.67 seconds 0-60. That's with a raised launch control rpms and suspension, light wheels, two piece brake rotors, etc. My S6 was consistently 3.9 seconds bone stock. Once tuned it got down to 3.4 seconds with just a simple tune. I skipped directly to stage 3 after that and it's doing 0-60 in 2.87 seconds now, limited by traction as it spins all 4 tires for good 10-15 feet. 0-60 is almost meaningless though as there are so many factors involved, like tires and so on. On the highway or a rolling start the S6 just feels solid in terms of power delivery. It doesn't sound or feel like it's struggling to deliver the power, it just keeps pulling more and more without making too much fuss about it. The torque from the 4.0tt is so much more and so noticeable that you can't even compare the two.

[Valpo A7]

Bored at work so I went searching the various A6/7 and S6/7 database threads.

I found a 2013 Stock S6 that ran 12.19 sec @ 113.07 MPH

I found a 2015 A6 with APR stage 1 that ran 12.56 @ 108 MPH.


Now understand these are just 2 of that data points collected and posted to the database threads. There are still a lot of factors to push the data in either platforms favor but the take away I see is it would be a very close run that could be won or lost on simply reactions times, traction, and gutting some weight..

[jcoleman_11]

Peak numbers don’t tell the entire story, and although the 3.0T can get you to 500HP with the dual pulleys, ported supercharger and wider throttle body, that’s only 20HP above the S6 at peak. Negligable. But throughout the entire powerband the S6 will have more torque. It’s at 450TQ as early as 2000rpm, whereas it takes the 3.0T till 4000rpm, and that is it peaking too, it drops off after that where the 4.0T sustains it till 5500rpm.

These are my best runs. I am not a lightweight man, and I know these are not ultimate runs compared to the internet, but it maybe offers a more realistic view.
S4 stock (as mentioned, similar to A6 motor, but weighs a little less.) [email protected] 440DA 4275lbs
S4 Stage II single pulley [email protected] 1265DA 4275lbs
SQ5 stock (as mentioned, similar to A6 motor, but weighs as much as an S6. Also has the aero of a brick.) [email protected] -148DA 4615 lbs
S6 stock [email protected] 874DA 4625lbs
S6 Stage I + TCU [email protected] 1327DA 4615lbs
and just for fun at mile high elevation in the 90ºF summer....
S6 Stage I + TCU [email protected] 9140DA 4650lbs
I'm interested to see if winter mods make any difference:
GFB DV+
RS7 full intake (including metal turbo inlets)
New 265 PS4S tires
034 rear subframe inserts

I also know a fellow mile higher who ran his A6 Stage II dual pulley with HX and TCU to 12.6@110 so pretty much on par with my Stage I S6 up here. Same track, different day.
Not making excuses, but the S6 Stage I even is traction limited and gets wheel spin on launch even down to 3500RPM.

It wouldn't be hard to get a tuned a6 to run beside a stock s6. Infact a dp e40 a6 can run beside a 104 stage 2 s6

He is asking about a TUNED A6, not a fully built with everything you can throw on the car type of A6. A just tuned or even stage 2 single pulley A6 will have a hard time keeping up with a stock S6. Period.

[pfar54]

To answer your question, yes a tuned/pullied A6 can compete, if not defeat a stock S6. This would be a minimum of stage II and potentially stage II plus. There are A6's running high 10's.

Your situation was similar to my own. I was considering the S6 vs. the A6 during the purchasing process. My car has basically every option, other than night vision. Getting the same specced out S6/S7 would have been anywhere from 50 - 70% ($20,000 - $30,000) more. I couldn't justify that cost bump for a car that is so similar. Though I do love boosted v8's, so it was a tough decision. You can spend $3,000 and get a car just as quick.

I also feel like the potential of our cars is far from being capped. Compared to other platforms that I've owned, the numbers of mods people do to the A6 is very low. There are roughly eight performance mods people do and that's about it (tune, pulley, HX, test pipes, tb, TCU tune, and low and high fuel pump). If you look at the S6/7 and RS7 community, they are replacing turbos and doing far more to their cars. You should check-out the 3.0 Facebook group page. There are some people on there looking to really push the limit of this platform. There's even a guy who turbo'd the 3.0.

He said, "hold its own". I would call 2. - .4 seconds behind holding its own. Especially when you look at the amount of money being saved.

He is new to this platform. He probably doesn't know much yet about DP. DP doesn't require that much more in terms of funds. This will run right beside an S6.

[TypingAllDay]

Based on these two spreadsheets, looks like a stage II APR single pulley A6 is on par with a stock S6.

I'm generally a fan of just getting the high-end model (M5 vs. supercharged 540i, for example), but for something like $3K you can have S6-like performance for $15k less than an S6 thanks to the huge potential of the 3.0 TFSI motor. Plus ventilated seats to suck all of your farts away. win-win.

[88BlackZ-51]

I was curious about a tuned A6 (both engine and transmission) with a pulley vs a stock S6.

The reason why i asked this question simple boils down to cost. My car looks as good as an S6 but it's missing 2 cylinders. I almost purchased one but the reason why i didnt was the exterior and interior are almost identical. The "S6" didnt't have that special look or feel that I expected for double the money in the used car world. Don't get me wrong the S6 is nice. It's no where near double the purchase price "nice" however.

I paid $16,000 USD with Audi warranty with (56,000 mile). Blk optics with power mirrors, shade, 20 inch rims, bose, camera etc....

And yes I am still learning but this isn't my first rodeo. I am big on value however. I hope this A6 won't disappoint after a spend roughly 2k on modifying it.

Just my thoughts. A6 guys might agree. S6 guys might not. It's what makes the world go around!

Understood.
The double price disparity was obviously not that way when new. Depending on options maybe +$10k-15k for the S6 which in addition to the motor got you supersport seats, carbon interior option, air suspension, sport diff. All things you could not get on an A6. At least in the US anyway. Oh and humongous brakes.
Just shows depreciation on an A6 may be even worse than the S6.

You are right on the depreciation statement. My car has already depreciated around 33% in the 1.5 years I've had it. And, I bought it used.

[pfar54]

I was curious about a tuned A6 (both engine and transmission) with a pulley vs a stock S6.

What kind of pulley setup? Single Pulley or dual pulley? 2k won't be enough to do either with a TCU tune. Unless you go with EPL. An APR stage II tune with SP will set you back around $1,500 alone. Then the TCU tune will be around $700 - $1,000. If you go DP, you will be in it another $800 - $1,200 (would need HX, DP setup).

[97B518TQM]

Saying that with only $3k you end up with something very similar to the S6 is laughable, to say the least. $3k will get you an ECU and TCU tune, a couple of pulleys, and a heat exchanger, at most. And that's assuming you do your own installation of the heat exchanger. The hpfp will be close to maxed out so you have to spend a few hundred bucks for that upgrade as well. And then you may or may not have an A6 that will keep up with a bone stock S6.. maybe 20-70mph. You still won't have over 400ftlbs of torque as early as 2k rpm, you still won't have 6 piston brembo calipers with 400mm rotors, you won't have adjustable air suspension, you won't have sport dif, you won't have the engine sound, you won't have the adaptive steering, you won't have the cylinder deactivation for longer trips at cruising speeds, and most importantly where the 3.0T in the A6 starts to run out of possibilities for more power that's where the S6 is just getting started from with just a tune....So while they look similar, the A6 and S6 are not that much alike, despite what people who can't afford an S6 try to convince themselves. I speak from experience. I was a 3.0T fanboy with what I thought was a super fast S4.

I'm sure we all realize that an S6 is a lot better all around but the OP asked if a tuned and pulley upgraded a6 will keep up with a stock s6 and absolutely it will. The 3.0 tunes have really improved in the last 3 years. My guess is your s4 had an older tune

An A6 with the mods you stated will be faster than a stock S6. You do realize there are tons of A6's in the 11's on here and the community, right? Then there are some in the 10's. I do wish I had the V8 sound and the air suspension. Everything else you said I could care less. They are attributes for someone trying to be douchey, bragging that they spent the money. I can easily afford an RS7 if I wanted. However, spending that much money on a car in my opinion, unless very wealthy, is stupid. But to each their own.

Regarding your bragging elements:
-We don't need cylinder deactivation. We get over 30 mpg on the highway as it is.
-I could care less about the Brembo brakes. Do you have any actual data that shows the time shaven off from the A6 brakes? Or do you just like saying you have Brembo brakes? I'm sure there is a performance benefit. But by how much? Does the extra thousands of dollars in the purchase price and lifespan really justify the performance? Would I like to have them, yes. Would they be nice, yes. Value is subjective. In my opinion, for the amount I am actually taking the car at speeds where these brakes would be beneficial are so low, it makes no sense having them.

Don't S6/S7's start getting transmission issues after stage 1? I see a lot of mid-11 stage 1 S6's in the spreadsheet that TypingAllDay posted. Getting to a mid-11 is very achievable with an A6. So while you say the A6 is running out of power and the S6's are just getting started. Can you explain? The top four posted times on the spreadsheet from Stage three S6's are 10.554, 10.697, 10.746, 10.847. The fastest posted time, at least that I know about, for an A6 is 10.8. How much extra money is needed to go from stage 1 to stage 3? I don't even want to guess, but I bet it is hell of a lot more than it takes to get an A6 into the 10's. Not even to mention the cost of the car, insurance, gas, etc.

I don't understand how you think a mid-11 A6. (with fuel mods would run this) is so much different than a Stage 2 S6 running an 11.3.

If I wanted a platform based on performance alone, it definitely wouldn't be an Audi A6/S6. It is nice to spend a little money on them and have a decently fast car.

Right but you'll have a car that's as fast or faster for 95% of the driving most people are ever going to do, and which looks nearly identical on the outside aside from badges and exhaust, and you're sitting in more comfortable seats - for way less money.

Do you really think there's much difference if you take a stage II A6 with sport suspension on a canyon run vs. a stock S6?

[BobbyWatts]

As an A6 owner I can 2nd what 97B518TQM is saying... I'm in for about $9k in parts/labor on my APR-Stage II... a maxed out A is close to a mild S that will still put gaps on you at highway speeds. At that point you have to get creative to bring power up in small incremental amounts. So you'll have to be realistic with your budget and performance goals/expectations. If not content with the car, they all depreciate - so cut and run early to a different vehicle or go all-in fast and enjoy it as much as possible.

I totally understand and appreciate the frugality. When i bought mine i was looking at used S4, A6, S6, and the S6 was 25k more for same mileage... my kid's carseat wouldn't fit in the S4, I still have fun, and they still have a college savings account.... expectations managed

[sickmade0331]

If your going to spend the 4-5k more tip get tip s6 power you might as well take the leap and just get the s6 you will not be disappointed. And you will never regret your decision.

Thanks for all the responses and opinions.

The A6 is no race car. I've driven a stock S6 and was pleased with the power. I will likely do a single pulley with the ZF tune.

My original post was in regards to the car holding its own with a stock S6 as I drove one that was $34,000.

If these mods aren't up to snuff I will take out the CTS-V on put it on kill mod. It's a much angery car (630 rwhp) then an Audi S6.

97B518TQM- You seem very passoniate about your car which is great. Just remember if I am stopped next to you at a light the good looking lady driving the Panamera isn't looking at the S6 or my A6. These cars are both very pedestrian looking.

Guess that's why guys own M5's and CTS-V's as they are lookers.

[bahula03]

Nobody asked if putting $3k into an A6 would turn it into an S6 The pretty simple question was if a stage 2 single pulley '14 A6 was ballpark as fast as a stock '14 S6 in a straight line, and uhh...pretty clear the answer is yes ¯\_(ツ)_/¯

Will be fast enough for me. Its an all around car including winter driving. Looking forward to giving this a try after warranty ends.

No interest in going dual pulleys. EPL can be done for around $2000 or less. They always seem to have sales.

You should look into facelift bumpers. It has an extended lip. Similar to what an CST-V has.

This is where I am going as well. Back in the day, I drove modified big block cars and you spent more time staying off the throttle than on. With Stage one APR in sport mode in a crowded city like Toronto, good luck in winding out a single gear unless you are on an on ramp to the 401/400 and that is short lived because the police are everywhere. Leaving Las Vegas and driving to Primm, there was a lot of opportunity for me to play with an S or RS, but not here. Trying to make a light shoots you to double the speed limit or more in 2-3 seconds which can get you a massive ticket.

Have to go to Toronto Motorsports Park to have fun. Looked at an S6. Didn't want to deal with turbos or DSG. I did want the diamond stitched seats, but my last A6 had the sport seat option and on longer drives, it killed my butt. It was like sitting on a baseball catchers mitt. I can't say I am disappointed in my choice. Great car for long drives with enough power via the APR tune to get you out of situations (like the a-hole who knew he was going to turn, that stands on the brake in an intersection and flips on his left hand turn signal in front of you). Cool temps and debris from road salting means when boost hits up top you are treated to many Christmas lights on the dash as the tires break free.

Actually I am not all that excited or passionate about my car and am already thinking about the next one. What I really don't like though is people trying to convince themselves and everyone around them something that's just not there. In this case that one can have an S6-like performance for $3k out of an A6 and that at the end it's a waste of $10k to spend extra for an S6 when you can have the same out of an A6. That's just ridiculous. I felt the same way 12-15 years ago when B5 A4 guys made the same claims that they can put on a GT28 turbo on their 1.8T and for $3k they can have the same car as a B5 S4. Two completely different animals, completely different driving experience, completely different torque delivery, and so on. And back then I knew that because I had transitioned from a B5 A4 into an S4 and knew what was reasonable. Sadly it's all repeating. I am sure RS7 guys feel the same way every time they hear an S6 owner trying to fool themselves and actually believe that it's pointless to get an RS7 when for $5k investment you get the SRM rs7 cores and APR tune and you are at least as fast as a stock RS7.

This is a really funny thread for any S6 owner who was given an A6 loaner.

I am not trying to convince myself that I will beat a stock S6 or that maraculsly my A6 is a S6.

I had 2 C6's parked next to each other in my garage last year. One being a 2009 C6 Z-51 and the other being a 2006 Z06. I knew that I could mod the Z-51 car and it would beat up on the Z06. But at the end of the day the Z-51 is not a Z06.

Now in saying this the Z-51 was a ton of fun and was great on track but then again it's not Z06 (427 sbc).

I am a car guy through and through and I realize all that you have said.

When I listened to mechanics that work on Audi's and read forums it was clear that a higher mileage S6 could be a maintenance nightmare costing a small fortune. These thoughts were not communicated with the non air ride, ZF8, 3.0 supercharged A6. Plus the flashes of the engine and trans with a cheap pulley swap put it in the performance of a stock S6 without the possibility of big money repairs on a 6 year old vehicle that deprecaiates like crazy......

This is a really funny thread for any S6 owner who was given an A6 loaner.

Truly a massive difference in power delivery both being off the showroom floor.

Actually I am not all that excited or passionate about my car and am already thinking about the next one. What I really don't like though is people trying to convince themselves and everyone around them something that's just not there. In this case that one can have an S6-like performance for $3k out of an A6 and that at the end it's a waste of $10k to spend extra for an S6 when you can have the same out of an A6. That's just ridiculous.

Even if it's $7-8K it's still way cheaper, especially when both cars were brand new and the cost difference between the two way greater. Now that the delta between a 2016 / 2017 A6 and S6 is ~$15k it's still cheaper to mod the A6 - but sure, maybe just spend the extra $6-7k and get an S6.

The farts don't really go away, they are forcefully wafted to the unimportant folks in the back seat. Jeez even my seats are supercharged!!

I can't wait to try this with my son. Father of the year here.

That's just ridiculous. I felt the same way 12-15 years ago when B5 A4 guys made the same claims that they can put on a GT28 turbo on their 1.8T and for $3k they can have the same car as a B5 S4. Two completely different animals, completely different driving experience, completely different torque delivery, and so on. And back then I knew that because I had transitioned from a B5 A4 into an S4 and knew what was reasonable. Sadly it's all repeating.

I agree in some regards, but the differences between the A6 (stage 2) and the S6 are extremely minimal. The very short-list of differences you provided earlier are minimal. You are acting like you are going from a pedal car to a rocket ship. Outside of the engine, it is 98% the same.

As I pointed out, the differences in 1/4 mile between a Stage II+ A6 and Stage II S6 are minimal, if not the same. You are backing your statements with emotion and not factual data.

-Do I prefer a V8/turbo over V6/supercharged induction....definitely
-If an S6 was the same price as an A6, would I take the S6...yes
-Is an S6 overall a better car...yes

However, they are substantially more. For a person who truly values cost/performance then the A6 is the way to go. I thought about selling my A6 shortly after buying it to get an S6, but then I really thought about how stupid it would be. I'm not going to dump tons of money into it to get into the 10's. I'll spend 4k with my A6 and get into the mid-11s.

I'll save that money and get myself a C8 Vette for $72,000.

No, it is not.

Tell us about the modified A6's you've driven.

At the end of the day everyone here needs to admit that both a6 and s6 are 4,000+lb land yachts designed for comfort and touring... Both can be made quicker/faster but neither will ever be a Ferrari. An near equal price tuned RS3 will rock us all in the quarter and for half the price there are kids with fully built turbo Honda’s running 8 seconds. Our chassis is neither, and will never be.

If all you care about is 1/4 mile - a6 is a 1 second sacrifice.
If you want to mash the pedal on the highway and keep pulling beyond 150 and brake a lot faster - go S6
There’s your real world difference.
