Better yet, go over to the BMW, Jaguar, Lexus, etc. forum and belly ache there. You will feel better and so will the rest of us.

Slides is not off base here. I had the same lag in my S6 - with over 450hp stock was ridiculous. It was even worse in the event you had pulled up to a stop, and then had to put it in reverse...it took WAY TOO long to engage before you could back up. Very dangerous in certain situations. My EPL ecu and tcu tunes remedied it. But then you run the risk of the dreaded TD1. I was sorry to read of this on the S5 - and potentially the RS5 which I am also considering. It is not the same with my Q7...guessing it has to do with the Supercharged V6 and tranny which are older versions - assuming the kinks are worked out.

Slides - don't listen to those who criticize you. You have the right to your opinion. And noone should really treat you like that in a forum. I've had 67 cars and been on many forums...some good, some not. Don't let one person deter you from being here.

I loved so much of my S6 and easily sunk 10k in mods. But the things I hated ended up winning over them.

Also - so everyone knows...I had a 2016 S5 as well. I didn't have it that long but I don't remember any of this issue.




This thread was particularly useful for a mental note when I drive both the S5 and RS5 SB.

To me it's not even subjective-- in D mode the car is barely drivable in anything but a scenario where you don't need responsiveness, such as cruising down an empty highway, otherwise there is a 1-2 second lag in getting power to the wheels. Even my girlfriend, to whom a car is nothing more than a mobile makeup/telephone booth and drives an Infiniti QX50, took it for a drive and simply told me that the pedal responsiveness "feels like Jello".

I want to reiterate though that the problem is not that the car isn't fast-- it's plenty fast if you floor the pedal off the line. The problem is predictable and smooth acceleration. I think the best demonstration of this is to try and keep a predictable and measured distance between you and the car in front of you when a stoplight turns green and he accelerates forward. What I find is that the Toyota Yaris in front of me will actually pull forward faster unless I mash the pedal, in which case I launch forward and risk rear ending him. The car is just very lethargic at tip-in. Basically the ratio of acceleration to pedal movement is non linear. Pushing the pedal the first X inches achieves little acceleration, which pushing it another half inch and suddenly you get a rush of juice. It just leads to a very disconnected feeling between you and the car.

Also no clue how you are managing 28mpg. I drive 8 miles each way to work, approximately 50% city/highway, and get 21mpg in D mode, and 16mpg in S.

I certainly didn't mean for this post to get so emotive .I didn't post this issue to get reactions from anyone. I am new to the forum , have bought a very expensive car and this issue, to me anyway, is a very real issue, whilst it may not be happening to all S5's it is certainly happening to mine and i am not happy about it, I just want it fixed because apart from this it is a fantastic car(except for the boot design , soaking everything inside when it opens!)

In D mode, you start in 2nd gear and that's also the lowest gear that the transmission drops to as you slow down or come to a stop. As long as you accelerate at a moderate rate, it will stay in 2nd gear and you don't get lag. However, if you stomp on the gas, the car will down shift to 1st gear before applying the throttle signal. That's where your 1/2 sec lag comes in (and you're slower off the line than using moderate throttle). It easy to learn the throttle position that will cause the down shift and avoid it. It's not like this car is slow even starting in 2nd gear. I've made left turns and crossed busy intersections without problem but if the cross traffic is really bad, then just shift into S mode for a bit.

There is a transmission software update that just went out in the UK that delayed the downshift from 2nd gear till you press further down so it might make it across the pond soon. Otherwise, just drive in S mode.

Moreover, swapping between those two is so easy and intuitive that I think it will become second nature. In fact "intuitive" is a great word to sum up this car for me. Just about every aspect of it feels so right that, in time, I'll overlook some of the styling foibles (mainly around the front) that almost put me off. I'm coming from a BMW 428i, that I thought was a great little car. In hindsight, with the perspective gained from my initial experience with the Audi, the BMW was really pretty ordinary.

I guess I'm in the honeymoon phase, but this is looking like a very promising relationship. I must find the thread on seat comfort, because that had me worried too, especially as I had some reservations during the test drive. I'm delighted to report that I've never felt more comfortable in a car.
