A8 rev match
Unless I’m missing something, I can’t find any mention of the A8 rev match feature when in manual mode. Lots for the M7. No mention in the owners manual either.
Is it just expected or just not worthy of mention ?

There is no rev match needed for autos. The transmission does it all for you.

The M7 has the rev match feature for manual down shifts of the MANUAL transmission .
The A8 the same paddles are now for manual shifting of the AUTOMATIC transmission.
One paddle shifts up and the other shifts down!
Nothing to do and is not REV match in any shape or form!

The A8 rev matches all the time, and this can not be turned on and off by the driver like it can on the M7.
Since there isn't a way for the driver to manually rev match on the auto, the computer does it by default. (after it gets done thinking about things for a little while)

Yes you are missing some thing and now being mislead.

The A8 the same paddles are now for manual shifting of the AUTOMATIC transmission.

This might be what OP is asking? Per owners manual -
If the left (−) minus paddle is held down briefly, the transmission will downshift to the lowest gear possible for the vehicle speed. If the paddle continues to be held as the vehicle slows, downshifts will continue to occur as vehicle speed allows. This feature also works while in Temporary Manual Paddle Shift mode, but the driver must first press and release the (−) minus paddle to enter Temporary Manual Paddle Shift mode, then press and hold the (−) minus paddle briefly.

It does blip the throttle on a deep downshift, but nowhere near as cool or clever as the M7 rev match, as it doesn't need to be. I don't think I'd call it "rev matching", but to each their own.

While cruising mash the pedal to the floor and release real fast, the trans will drop gears and you will get a message in the display saying performance shift mode, once in this mode you will notice the trans will be much more aggressive.

If the A8 didn't rev match on a downshift, the A8 would simply pull the engine speed up as the lower gear clutch engaged, and it would shock the tires.
It doesn't. During the downshift, the throttle blips the engine up to the correct speed, so that when the A8 clutches engage the lower gear, there is no shock to the tires. It's a rev match.

Cruise along in Drive with an A8, start slowing/braking for a light and click the left paddle for a lower gear to help slow down. You'll feel a little surge as the engine blips a little and the revs are still a bit 'up' when the trans. drops to the lower gear. Call it what you like, but it is NOT the transmission simply engaging. My SL55 does NOT rev match and you feel an immediate deceleration as it shifts down and compression in the the lower gear slows the car.

The paddles don't work in "D"

The paddles DO WORK when the car is in D. This allows you to manually override the automatic gear selection process. If the car is kept in D the car will revert to automatic gear selection in a few seconds.

Sure, reading and comprehending the owners manual is harder than reading "Dick and Jane", or other first grade level stuff.

I don't use the paddles! The car is faster in all respects when it is in "D"!
