The S4 suffering the same, now that is confusing as it's engine is all but the same as the S5 and being both N/A 4.2v8 I can't understand why you are feeling a delay between pressing the throttle and the car taking off, that's a really funny one that.
The Q7 was a 4.2 but both the S4 and the Q7 are automatic in auto mode. I am not sure if this is a transmission issue but I expected power surge without downshift since they are v8s.
