Have you heard the S4/S5 rumour...

I would hope that the 2020 version would also be getting the same interior update as the 2020 A4 & 5...

So the S4/S5 3.0 V6 TFSI only lasted in the SQ5 for barely 2yrs (was TDI up to 06/17). Am I correct that in '17 Audi had emission/consumption problems with the S4/S5 motor, as it was affecting the overall fleet consumption benchmark? There is now a mild-hybrid S4/S5 3.0 V6 TFSI power train.
I was of the understanding that this corporate mild hybrid 50 TDI power train was initially installed in the A8, producing 210kw & 620nm. Suddenly this new SQ5 gets an extra 45kw & 80nm???...and there is more with DTUK. OOPS, it's an oilburning SUV. :-(

As stated previously, it makes sense to power a SUV with a diesel, but not a proper 'S' car...

I hope they make an a7 version!

I don't think it's necessary for the a4 to get that engine as otherwise it would steal sales from the s4 which I still can't see the rumour being true

Most likely that engine will come to the a6/a7

My mate, the Audi wholesale manger, traded their ML63 for a dark blue demo SQ7, with sports exhaust and bulk bells & whistles. Been in it and sounds magic for a diesel SUV.
A4 V8? Audi went V6 turbo for less weight, better handling and economy.
Trivia - his current 'drive car' is a near new GT2 (245x35x20 fronts with 315's rear). When he downshifts to take the corner opposite home, O-M-G!!!

V-e-r-y interesting, particularly "Audi Australia corporate communications manager...said it is interested in bringing the SQ5 TDI back to Australia to sit alongside the 250kW/500Nm SQ5 TSI”.

No reason why they can't have the two engines in a SQ I guess...

So, is this new a4 gonna have the a6 interior update? And are there any signs of the face-lift RS4? I honestly thought we'd see a performance variant but I know it's more likely in the face-lift iteration. As per RS6/7.

The S4 diesel rumour is mentioned in the latest Evo magazine (page 146, issue 259 - I subscribe and it landed on the doormat yesterday). Its mentioned in an RS4 Fast Fleet article. It makes it clear it’s just a rumour ... but Evo are very well connected. Just sayin’
I really Hope it is just a Rumour Audi S Cars appeal to a lot of young folk in my age Bracket. Can’t see many people being excited by a Diesel S car? If that’s the case you may as well Buy a 3.0 Tdi A4/A5 and remap to get similar performance to a diesel S equivalent.

Quite, I posted up a reference to these engines in another thread but it does suggest Audi do have the options..

Didn't know.

Still extremely interested in how they came up with 255kw & 700nm in the new SQ5TDI. A6/A7/A8 mild hybrid 50TDI has 210 kw & 600nm. I knew Audi had made major improvements to that engine to go into the A5 & Q5, but had 210kw & 620nm (no increase in kw for all that development??).
Now suddenly this engine appears.

The 210kw versions are the single turbo variant though aren’t they? Rather than the more powerful twin turbo version in the SQ5?

Yes - 210kw is single turbo, but unaware a twin turbo 3.0 V6 TDI in the current line up existed.

Yes, a variant was in the previous diesel SQ5 as well as in the A6 and A7 with higher output.

Noted, but none of those are the current crop of mild hybrid TDI's. Also none of the 'blurbsheets' to date say its biTDI.

The diesel SQ5 has gone from a twin turbo to single turbo with electric compressor AFAIK, meant to spool better but published performance figures look almost identical?

As I understand, the single turbo with electric compressor is, in essence, the mild hybrid system. As with many electrical items once one turns it on you have full electric power instantly. In a vehicle, when one accelerates the electric compressor cuts in immediately (hence no time lag) until the turbo can spool up to the required pressure. There will be improved acceleration, so theoretically improved economy, but not an increased total power output.

My point is that the mild hybrid technology is already in the A6/A7/A8 50 TDI, the same 3.0 V6 single turbo diesel engine as in the SQ5.
So exactly what did Audi do to make the SQ5 engine more powerful?

I can only assume that by having the electrically driven compressor for the quick response it means they can crank the boost up on the exhaust driven compressor (whether that's a tweek with software/hardware or a new larger version) without having to worry about the resulting lag and get more overall power as a result. Just a guess though.

No clue as too what makes it so powerful and I have only this to go on https://www.autoexpress.co.uk/audi/...-mild-hybrid-diesel-pumps-out-700nm-of-torque
However they are stating the compressor produces pressure to the turbo intake with a separate hybrid system..
That is how the electric compressor overrides lag, as it pressurizes the intake immediately the driver presses the accelerator, until the turbo spools up to that required pressure.
As I understand, the electric compressor does not take the place of a second turbo, it complements the single turbo to reduce that turbo's lag to almost nil. Think I read .005ms (I take it millisecond)

Why the 2019 SQ5 3.0 V6 TDI so powerful - it has a bigger hairdryer! Now with 2.4 bar, in fact.
It is significant that the TDI is within 5kw of the 3.0 V6 petrol TFSI in power, an area diesels often fall short. Also has +200nm.
Perhaps this is a large piece of the rumour puzzle.

Audi Oz also sent me this link. Extremely interesting and refers to the further development of the 50 TDI I was trying to find. Also confirms the 3.0 TFSI petrol, as in S4/S5, was built to accept mild-hybrid.

Shame no pics of the interior, although they also say it'll be similar to the top end models, real exhausts though :)

Yup, the RS usually is goes into production later than the standard models. I wonder if there is a OLED option for the rear lights...

Note the "We cannot afford to develop cars which do not respond to our customers’ wishes”.
Are they actually listening though?
Yeah I just read this. All I'm hearing is blah blah blah blah, we're saying the words but, we're not actually going to do it. All I got from that is, we're going to move to electric whether our customers want it or not. Acceleration is the most important factor and electric will be better at it annnnnnnd, we're going to try our best at making them handle well.

And what was that nonsense about the current RS6 being a V6? These people get paid money for writing things haha.

They'll have to move to electric anyway, whatever, as and when zero emissions come in. It could be interesting to have the option of both before then though. Certainly Tesla has shown it is quite possible to have a 'interesting' car. I certainly wouldn't mind a A4e version for the mileage I do each day...

Tough times as leccy cars imho have no soul given they have zero sound other than a whine. If you then introduce artificial sound (as I'm sure they will after a while) again not for me. Doesn't matter to me how fast they are indeed I was beaten to a pulp by a P100D last year on a 200m sprint!

They don't but in reality, with today's turbo engines, catalytic converters and gpf's the exhaust sound is becoming very muted anyway. I would put performance over noise any day...

Completely agree on this. Two weeks in a Tesla S p85 almost sent me to sleep despite the pace. Cars will become very much white goods to me when electric is mainstream and I will find something else to blow money on!

Slightly OT, but here's a link regarding the new RS4. This one is definitely staying petrol-engined:
https://www.evo.co.uk/news/22440/2019-audi-rs4-facelift-spotted-testing
Interesting - are 2 of the 4 exhaust pipes blanked off, or are there only 2 pipes?
Would appear the only Porsche development of its 2.9 V6 bi-turbo is either tickling an extra 15kw for the Cayenne, or coupling with an electric motor of 100kw for its Panamera.

CEO Bram Schot said: “We cannot afford to develop cars which do not respond to our customers’ wishes”.
Seriously. Motor Manufacturers are infamous for building vehicles they want to sell, not want the customer wants.
Please do not insult our intelligence!

This is an excerpt from an Audi Media Centre release 14/3/19:-

"In the first months of this year, Audi is successively closing the remaining gaps in its product offering from the changeover to WLTP and is creating the conditions for a positive sales development. In the course of the year, inventories that had been ramped up in 2018 for supply management during the transition to WLTP will be reduced. For example, Audi had already gradually restarted the production of engine-transmission variants for which the company expected type approval in the near future, in order to ensure rapid availability for customers following official approvals. Once the required homologations have been received, these pre-specified vehicles will gradually flow out of inventories. In addition, the company is making intensive preparations for the next, equally demanding, stage of the WLTP test cycle, which will come into force on September 1, 2019 with even stricter legal requirements for all vehicles. Audi has increased its technical test-bench capacities by around a third in order to make implementation more manageable, and has added approximately 300 employees in Technical Development for homologation and powertrain development. The company has reduced its portfolio of engine-transmission variants by about 30 percent in line with market preferences, thus noticeably reducing complexity as a first step.

This year will again feature a tight schedule of successive market launches. In total, Audi will once again present more than 20 new or updated models in 2019. The brand is sharpening its sporty image with nine new S models as well as four especially powerful R and RS models."
