Biturbo sports diff

[chiefbadger]

Quick question for those with the biturbo already!

I'm looking at chopping in my Ultra and stuck somewhere in the middle of deciding between a biturbo (sensible choice!) or a new RS3 (impractical but I've convinced myself it will be fine) and just wondered if anyone had specced the sports diff on an a6/7 and if so whether it makes much difference. Given the relative bulk of the A6, it's not exactly a car to hustle in any case so just wondering whether it is really as necessary as say an S4?

I love the a6 but just craving a bit more speed/fun/noise.

Thanks,
Ols

Get a BiTDI and an after market sound enhancer module for the active exhaust. Fun, loud and 46 mpg on a run (in the A7 that is)

I have the Sports diff on my RS6. You can select how it behaves in the MMI (comfort > auto > dynamic). The setting appears to make no difference at all in my limited experience. I suspect you have to really be ragging it to notice the difference. Not something I would specify as a costed option.

Perhaps if you put the car on a track, or live in North Wales (which is much the same thing as putting it on a track, but with the added thrill of a possible sheep hazard) then it would be different, but in the built-up South East, I suspect I will rarely - if ever - get any benefit from the extra drive you are supposed to get in tight, fast corners.

Thanks for the insight on this. That's pretty much what I was thinking. I normally have my wife and kids in the car, so it's never going to be thrown around in anger, but there are some nice B roads down here (sussex) and on the odd occasion I might get out on my own, it's nice to be in something that feels dialled in. Certainly wouldn't be taking it on track.

The 'driving pleasure' is the reason I'm after an RS3 but the biturbo is a whole lot of car for effectively the same price as the RS3 when discounts are taken into account.

I have found that there is an alarm in my car that sounds every time I start to hustle it along - it often goes off even before I have even really put my foot down. It makes a "don't do that while I am in the car" sound repetitively and emanates from the passenger seat. If I had know the alarm was quite as effective as it has turned out to be, I would have bought the entry-level A6 - and definitely no need for a sports diff.

[chiefbadger]

By the same rationale, their is also zero need for the Bose!!

I find the Bose, if used correctly, extremely useful in drowning out the annoying whine coming from the passenger seat.

The standard biturbo is still fun to drive in my opinion. I can actually generate a scream from the passenger seat if I sneak a launch control in when she's not concentrating. I live on the edge of the Peak District and drive pretty quickly when on quiet roads, sticks into the corners well and with the quattro you can accelerate out really early. Despite being bigger the extra torque will still give you a shove in the back that competes with an RS3.

The sports diff. won't be for everyone, it sounds nice but it's a different animal.

Basically 99% of the time you don't know it's there, but when you go hard into a corner (late brake) and steer to compensate, then you feel it, it's like someone got hold of the rear and swung it around the corner for you, where normally you might lose the tail and over steer the front. It is a weired feeling and like I said, in normal driving it won't happen often and it can be disconcerting when your not use to is... like when anti lock brake came in and you steer, you are expecting the front to give way, but it still grips.....


If your in with the family it's not a feature your going to use, if your out on a b road on a Sunday, you might just notice on a fast tight corner...
If you get one, practice in a big private area... so you know.

[chiefbadger]

My car happily goes sideways without the need of a sports diff but speaking with a fellow Biturbo A7 user @409BHP he tells me its a great thing. I pondered adding it but decided to add MMI advanced instead ( Which is nothing special).

Cheers Jamie. Another question - is the colour display now standard? On the config, looks like it's only available via the tech pack now?

It makes a difference. It took me a while to appreciate it. Once figured out when it kicks in, and how to change my driving to take advantage of it, the combo of Quattro and sports diff makes going around bends amazing. It comes into its own when entering corners quicker than your mind tells you should be possible, it does so with no drama and without feeling like you're on the edge. The reward, it doesn't feel like you're on the edge, accelerate through the corner and it's the gift that keeps giving.

Where I disagree with noscream, it makes 'driving' possible with the family in the car. I will caveat that I live in an area with many B-roads, which provide opportunity to safely take advantage of the sports diff.

Would I buy it again... probably, however as we progress towards hybrids and electric cars, I expect it will be standard. Right now, the option I would put above sports diff, is adaptive cruise control.

[Westyfield2]

My A6 Avant does not have the Sports Diff, and seems fine with 470BHP. But I've never driven one with the Sports Diff, so I don't really know what I'm missing.

No that's impressive... only 88bhp/72ft lb down on the RS6 :aargh4:

[ukgroucho]

Tried (and experience as passenger) sport diff in my brothers S4 and it is impressive when being a loon around tight curves on big throttle openings - such as left turns from traffic lights on american roads or some of the funky on ramps they have for the freeway... blasting around the outside of other stuff (particularly american dino-cars with huge engines and 1960s suspension that think they have a chance)

I KNOW it grips more than my allroad... now some of that could be the lighter car (although amazingly not much lighter), low profile tires and shorter wheelbase but I'm pretty sure some of it is the active rear diff. And the supercharged TFSi has a more immediate response than the BiTDi so more inclined to lose traction if you are a lead foot.

Having said that ... on the allroad I don't think I'd bother. Not unless I was inclined to do 19 or 20" wheels (lower profile) etc.

[wildbore]

Nice Pics ! Interesting to see your BHP is 84 higher than mine but my torque figure is still 170 Nm higher.
27585

In fairness, though, the petrol engine has a much flatter, wider torque curve that will make for very rapid progress on the road. Diesels develop stunning headline torque figures but they do so within a relatively narrow band of engine revs, as the two graphs posted here show. Still, got to admire your maximum torque figure, though. Is that going through the ZF 8-speed auto?

No its plenty quick enough for now. Just I dont get the whole comparing modified cars to standard variants.

[chiefbadger]

So, having mentioned the S4 earlier I actually started looking more closely at them. Looks like a sizeable saving to be had on them as they are due replacement next year with the b9 but I was quite surprised by the quality of the interior etc. Sure it's a little dated (particularly things like indicator stalks) but it's still a very nice place to be.
As much as I love the space the A6 offers, it is a b&gger getting around multi stories etc so really quite tempted by a bit of a downsize. Sure the buggy will still fit . . .

Seeing what's possible from the 3.0 petrol lump is also quite appealing!!!

The funny thing is, that's still on the standard exhaust :Blush2:. Also there's apparently more to be had if you also remap the S-Tronic gearbox to raise the rev limiter.

Chris Harris was so impressed with the S4 Avant which Audi used as the press demo, that he went and bought it afterwards.

Make sure you get a good deal though, and yeah I know what you mean about the interior. By all means the B8 isn't a *bad* car... but at the end of the day, it was released in 2007 and is getting on a bit now. It will be quite a step down from a C7 A6 in terms of technology etc. Unfortunately the prices of an S5 Cabriolet don't really reflect that :(.

I assume the answer is "No", but I'll ask anyways.... can the Sports Diff be retrofitted?

Hi Chief,

Probably not dynamic enough for your current needs but maybe you should consider test driving the SQ5?

Would fit in with the 2 young ones too. I guess you need to drive and test both the A6 biturbo and SQ5.

can't wait to see what you go for.

Jukkha

[M1tchy]

I test drive the Q5 last weekend and the inside is old and dated and the dealer reckoned it was due an upgrade which they think will be announced within 12 months. The A6 is a much nicer cabin. That said, there should be some big discounts if the Q5 is due to be replaced soon.

I've been thinking hard about which way to go with this and slowly making some decisions.

SQ5 is a no for me as I just don't like the image. I'm also less interested in pure 'grunt' and quite keen on a bit more driver involvement. Basically I still want an RS3 but it's just too small!

So . . .
S4
335i M sport
335d xdrive
Golf R estate

Are the options I'm now looking at. The 335d actually looks really interesting as basically a slightly smaller biturbo in BMW clothes by the look of it. Now quite sure I can get comfy with the image, but having a drive at the weekend in both petrol and diesel.

The only thing stopping me from going S4 is the imminent replacement. As with the Q5 it is feeling a little outdated inside. Although still much prefer the external to the BM's.

The golf is an odd one. The interior is naff, the 4 exhausts look terrible and the deals available aren't great, so it's actually not much cheaper than the others. But . . . Having driven a 5dr DSG hatch last weekend, i had a very big smile on my face. Granted it's not exactly a sports car, but for what I want - it does seem to tick a lot of boxes. Just struggling with the fact that it's a golf though.

Anyone have any real experience with any of the above? Would love to hear from you!

Sounds good to me. I understand what you mean by more driver involvement. As much as i love my Ultra avant, it is a bit of a 'Barge' like you say. Luckily I swap with my brothers Cayman S every now and again. Although I do admit, 90% of the time while driving the Cayman I do prefer driving the A6 on a day to day basis. It's that 10% of winding and sweeping roads etc that put a smile on the face for me.

My cousin has a C63 that gives a lot of smiles (mainly down to that engine), have you also considered a C63 Estate (last of the previous model?) I guess it depends on what sort of mileage you do etc.

Either way, all of the above sound good too me that you mentioned. Can't wait to hear about the test drives.

[chiefbadger]

c63 is exactly what I want! Just can't find one that is right. Also although purchase price is similar, financing one is much more expensive due to higher apr's etc.

Some of the c63's look a bit aftermarket already to me so would want one in a subtle colour with the 18"wheels ideally, and no bright red leather inside. Ideally 13 plate or younger with low miles (as makes a difference when looking at finance).
Also needs to have the LSD so a pretty tight brief. There is nothing available (that I can find at least) that is sub £45k and realistically late £30's is where I need to be. Otherwise it's RS4 territory again on price and I just can't stretch.

After weeks of procrastinating I pulled the trigger on the S4 today!

Kept the spec fairly basic but with the my16 changes I get the HDD nav thrown in which is nice!

Gone for:

Sepang blue
Folding mirrors
F & R parking sensors
ADS & DC
Sports Diff
Storage pack

Only thing I really wanted but couldn't stretch to were the SS seats. Couldn't justify an extra £35 a month for seats!

Looking at bw28 as things stand. Got a cracking deal through carwow too, can't wait!

I am sure it fits your needs perfectly with the sports diff. I take it this is the saloon not avant?

Blimey, didn't realise how much time has passed. Just thought I'd post a quick update having said goodbye to my BE Avant Ultra last month and collected my new S4.
Missing some of the toys and creature comforts from the A6, particularly the lighting pack with the door handle puddle lights, but am loving the speed and feel of the S4. The engine is fantastic!!! It's also very thirsty, my mpg has halved, but then I was expecting it to. Anyway, a few pics :)

Thanks! I was really unsure about Sepang Blue, but I really like it. I just wanted something a bit less bland (not sure if Daytona can be described as bland, but you know what I mean!) but was worried it might be a bit loud. It is in the sun, but very changeable depending on light.

I've done nearly 1000 miles in the last few weeks. It really is a cracking engine. Having driven and RS3 and RS6 on an Audi RS day before collecting the S4, I was worried it would feel a bit tame, but I was pleasantly surprised. At legal speeds, it is a very quick car and feels far more agile than I'd expected. It's not exactly tail happy, but you can really feel the rear getting a proper chunk of the power.

It feels a lot smaller (and certainly internally) is a lot smaller than the A6. I hadn't really quite realised how much shoulder space you get with the A6. It feels a whole lot narrower in the S4. The plastics feel a bit naff compared to the A6 and you can definitely feel it's a generation behind. Having said that, within a week or so I was thinking 'cor it's nice in here' so probably just testament to how nice the A6 interior is that it makes most things feel a little low rent when you first see/touch them.

Space wise, we have got rid of the double buggy, so the boot is fine. It's still always absolutely jammed full of stuff, but so far my wife hasn't shouted expletives about buying a 'stupid small car' like she definitely would have had an RS3 arrived.

I am loving being back in a petrol (apart from the consumption!!) and having an petrol engine with so much torque is great too. The acceleration from 20-40 and 30-70 etc is great and it sounds lovely. Quite discreet, but nice and purposeful. Struggling to get much above 20mpg though, which is a bit painful! Probably not helped with enjoying the performance so much though!

I mentioned that I miss the lighting pack on the A6, it's also particularly annoying in the S4 as some of the internal lights are led and some are standard. I'm way to lazy to change them, but it does aggravate me.

Other things I miss are:

Arm rest/storage - the A6 set up was just great.
Front ash tray - brilliantly damped change holder in the A6. Naff old thing like a 90's ford in the S4.
Rear load cover - not automatic in the S4. Really bugs me for some reason!

General quality of the S4 just feels a bit less too - things like filler cap, boot floor, various small bits that don't really make any difference but are just noticeable having come from the A6.

Bottom line though is that I am really enjoying it. It's narrower and more nimble, still has enough space for us and it properly flies.

I think it could be a keeper for a few years. Although if and when MRC crack the new ECU then the promise of 480bhp with the car looking completely stock will be very hard to resist!!

Funny timing... spoke with my twin brother in California on Monday and he said he was considering chopping in his S4. Had it 5 or 6 years and 95K miles so felt it was time. He was thinking another S4.

Tuesday he calls me and he's in a new facelift A6 3.0T (the same supercharged V6 that the S4 has). Basically he could not find an S4 in anything but black (which is a killing jar in the California summer), factory orders take an eternity and this Ibis white A6 was sitting in the Audi showroom so he went for that.

He is loving it - for all the reasons you are missing stuff in your S4 compared to the A6. Quieter, more comfy, better cabin etc. It is a bit softer drive (it's on 19" wheels I think) but he's happy with that - and the seats are a whole lot more comfy. Engine wise he does not think there is much difference in performance, but his S4 had a slightly less tuned version of the 3.0T - I think they upped it to 340bhp or thereabouts now.

Bottom line is the are both lovely cars. Enjoy the experience!

[Whippy53]

I often wonder why we don't get that engine option here, if we did I would be in the dealers tomorrow!

[Chesterfield313]

Because the biturbo reduced the 3.0T to five cars a year, so they stopped selling it here. And for good reason, I've driven both and in everyday driving the biturbo wipes the floor with it.

In America you can't order the biturbo, I think for emissions reasons (let's not go there) and they will hang onto petrol engines forever, just like the second amendment.

[ukgroucho]

Yeah will be interesting to see how he compares my allroad BiTdi when he is over in early November. He's been in it before and commented that it has as much or more in gear pull as the S4... it's just a very different delivery. The S4 is very immediate in it's power delivery - I guess the s-Tronic box helps and the supercharger certainly does as there is no spool up time. His A6 3.0T will have the same blower but it's actually the ZF 8 speed slush box that the BiTdi has - he reckons it feels as quick shifting (at least manually) but will see if opinion changes, early days yet (and he's in Germany right now).

So now he has a 3.0T (or "S" - supercharged) with the ZF box... in an A6 (albeit a saloon) so good comparison.

[Westyfield2]

S4 looks nice!

Is it another new ECU model? The one in my C7 was a newer version that the B8 S4, so took them a while to crack.

Yep. The 3.0TFSI engine is the same thing whether you've got it in an S4/S5/SQ5/A6/A7. And for every model year they tweak the map slightly. But it's all the same thing.

Thanks! It's definitely getting under my skin. Love how can be two such different cars so easily. With the ESP fully off, the diff is just fantastic. Really adjustable mid corner.

The ECU is now a Simos 16.33 whereas the 2013/14 were Simos 8 something I believe. They've also slightly altered the supercharger design and tweaked a few other things which escape my memory!

MRC/APR/Revo etc are all working on the new ECU but nobody's cracked it yet.

I often wonder why we don't get that engine option here, if we did I would be in the dealers tomorrow!

We did. But 99% of A6 buyers were obsessed with diesel, so low sales figures caused Audi UK to stop selling it a while into the C7 production (roughly the time that DAB became standard).

They're rare, but a C7 3.0TFSI does exist ;). Mine:

A6 Avant S-Line Daytona Grey | 3.0 TFSI | 7-speed S-tronic
As-well as the bodykit, sports suspension, and sports seats, the S-Line trim level gives a bit more kit than is standard on A6 base spec (Xenons in particular). Then the options fitted above what S-Line gives are:


Technology Pack
Audi music interface
Front centre armrest
Colour Driver's Information System
Mobile telephone preparation High with online services
MMI touch
MMI navigation plus
Radio system for MMI plus
DAB
20" alloy wheels, RS6 5 segment-spoke design. 255/35 R20 tyres
Heated front seats
Extended leather package
Fine grain ash brown Inlays
BOSE surround sound system
CD changer
Ambient lighting (The better of the two lighting packs, LEDs everywhere, extra lights in door pockets, door handles, sills, etc).
Deluxe 4-zone automatic air conditioning
Through load with ski bag
Electric folding/dimming/heated mirrors
Rear cup holders



Tuning:


Injen Air Intake
Eurocode adjustable anti-roll bars (front & rear) with billet aluminium front and rear droplinks
MRC stage 2 supercharger pulley & remap

Ah right. Yeah Simos 8 was the B8 S4. Then Simos 8.5 was the B8.5 and the C7.

Everything I've read always says the sports diff is great! Sadly my C7 only has the normal diff :(

I reckon you might just have the perfect set up there! Bet it feels fantastic with the mrc tweaks.

Mrc feel confident they'll crack it, but it's been circa 12months so far . . .

The sway bars look great - where did you get them?

I got the whole set from Eurocode tuning. Bars, endlinks, and fitting kits. Shipping and customs from the USA obviously wasn't cheap though.

I chose the Eurocode ones as all the forums say they're the best. However if you want to save the shipping & customs, there might some EU suppliers that do the C7 chassis also (Stasis/APR/ABT/MTM/H&R).
