Rev matching

I've never owned a car that had rev matching on down shifts.

I was told that my SL has this feature but, I can't tell. When I drop a gear it just seems like the torque converter is dealing with the mis-matched RPM.

Any input?

I just tried it on my new car and I'm like you in that I can't tell that the throttle is blipping in manual.

It would probably be much more noticeable in the higher rev range 3-4k rpm than in the lower range. My C63 with the automatic transmission is the same.

I was just reading abut the new Corvette. With the manual transmission there is rev matching. I don't know about the automatic.

For that matter, I don't even know if the is rev matching in any automatic.

Been a couple years, but as I recall the SLS cars we got to drive during an AMG Academy event had rev-matching in S+ mode. We didn't get to use S+ all that much because the cars were overheating - it was unbelievably hot at Road Atlanta
