New 3.0 turbo S5 vs previous 3.0 supercharged

[Ice_2k]

Hey guys,
I'm currently driving a B8.5 S5 SB and loving every minute of it. Thinking about my next car a few years down the road, I was wondering if anyone here moved from the B8/B8.5 S5 (just the supercharged version) to the B9 and can share the experience so far. Is the turbo lag significant, especially coming from the no-lag SC version? Is the switch from the dual-clutch to the torque converter noticeable? Or any other details you noticed while making this switch.

Thanks :)

go drive it. thats the best answer you will get. everyones impression is different. i actually like the new torque converter better than the twin clutch. others will disagree. its personal preference.

[Ice_2k]

Yeah, that would be ideal but I'm in eastern europe and over here people mostly buy diesels and 1.6 petrols so no dealers have performance cars for test drives...

[m-ys4]

i love the new engine, drives differently of course. all the new technology makes it an even bigger joy to drive. trade up!

[GreyLens]

Trade up for sure, imho. The dual scroll turbo brings a lot of torque right down to the 1350 rpm spot...plenty of low end torgue. Also, the tranny is a surprise...I like it better than the dual clutch. Granted it doesn't have that "second kind of cool" but it shifts fast and smooth. I'm looking forward to track days and regular Solo events.

As above, I preferably the new tranny, no low rpm low speeding clunk. The tech, there is basically no turbo lag with the twins scroll. Pleasure to drive and is quick to boot.

Thanks a lot, guys

There is more usable power in the B9 S5. The B8.5 supercharged motor bypasses the supercharger in a lot of situations and driving habits. A tune would clear up that problem. Stock for stock the B9 is a better car.

What kind of situations are you talking about? Not sure what you mean by "bypasses the supercharger"

[Jimmy ny]

The supercharger has a bypass valve. Bleeding off boost. The tunes disable this through the ECU. Do a google search and you will find more indebted information

It has more torque than the B8 but significantly more lag of the line.

[hsjyes]

Significantly more lag? I don't think so.

I agree. The lag time is very short.

I had 2 S4s a 13 and previously a 10. Both were supercharged & DSG. I drove the living h#ll out of both cars 70,000 km per year. I had them both for two years. If I were buying another S4 I would have preferred the supercharged engine. Since it's gone there is nothing we can do. I agree test drive the new one & see how ya like it or hang onto what you have. Happy hunting.

After driving my S5 SB since March, I must say that the turbo lag off the line is a disappointing change from my S4... i’ve only owned one supercharged car (S4) and one turbocharged car (S5)...and I much, much, much prefer the more linear power delivery of the supercharger. Sometimes the S5 feels like it has only 150 hp off the line.....for just 1.5 seconds....and then the turbos are spooled up enough to deliver the remaining power.

Outside of swapping the turbo, I’m hoping an highflow air filter, cold airtake and exhaust improves the lag...and maybe will have to go stage l...

You find this in S mode? 2 things:

If you are in D, of course it is slower.

In all drive modes, the transmission does not shift to 1st gear until a complete stop (even 0.5mph of movement will keep you in 2nd), you have to force it with the paddle. It's very annoying that the transmission does this, but once you know to tap it down to first (or drive in manual as I do) there is no scenario that behaves per your description.

Yes, this is in Dynamic and S mode. I did notice the car holding 2nd gear at stop signs, etc...which doesn’t both me. I’m describing off the line performance...from a complete stop...and the immediacy of power with a SC in the B8 as compared to a turbo in the B9.

I have both a 2016 S4 (6MT) and a 2018 RS5. The difference between the two is dramatic. Both pull consistently from start but the RS5 is so much quicker off the line (in S transmission mode), it's insane. I miss having a manual transmission in my RS5 but that is the only thing I miss. Driving in paddle mode is an improvement over pure automatic but it's not the same. :) Well, that and the AWE Touring exhaust that I have on my S4 but I'm hoping AWE will make my RS5 happy in a month or so.

[Ice_2k]

It’s pretty normal for your scenario. RS vs S, auto vs manual.

[zoomzoom!]

I had the SC 3.0T in my 2013 A6, and now the Turbo 3.0 in my 2018 S5. When driving in Dynamic/S, I have no complaints off the line.

[dreaddontdie]

Lol...guess I’m the odd man out....that’s cool, that’s cool...

I'd respectfully have to disagree here. I had a B8.5, stage 2 and comparability speaking, my S5, in dynamic/S mode was on par with it in term of getting out of the hole.

To all those saying there is no lag, I'd agree when making a normal start. But if you try to floor it from a dead stop, without doing a standard launch, there is a very noticeable lag. In fact, I've done several measurements using dragy 0-60 with launch, and 0-60 by just flooring it and it's a good .5 sec slower. If you are stock it will be about a 5 sec 0-60.

Again, if you launch it properly, it will be right at 4.4 0-60 and you will not feel lag, obviously because of the build-up of boost, also if you pull away at normal speed you will feel little to no lag, but if you try to floor it from a stop you will feel it and your car will be slower than a b8.5 doing the exact same thing.
