Default Downshifting PDK

My "new to me" 2013 Base Boxster ... I noticed for the first time that it seems to "blip" the throttle when I downshift using the paddles...
My 2019 Macan S does not do this.....??

My 2014 981 Base blips the throttle both on paddle-induced downshift and brake-induced downshift...I wouldn't have it any other way.

Yup... auto-blip (on my '15 CS) is a nice perk of the PDK system. Love it... especially when at speed and down-shifting at higher RPMs!

Best tranny ever. Absolutely love my PDK. Including the rev matching blips.

So...why doesn't the Macan S also "blip"?

Its called "rev matching" on the 981 variants, and its essentially electronic heel/toe for the track. The pdk on your Macan is not the same PDK in your 981. The Macan uses an Audi transmission

The PDK has to rev match in order to downshift, in all cars it's installed in. If it didn't, believe me, you'd notice.

Does anyone know of the Macan claims to be a true DCT? Lots of cars have paddles to shift, but that doesn't mean dual clutch of course. The so called PDK in the Macan is not the same Porsche PDK used in other cars as the Macan and Audi Q5 are the same platform with different badges, and the Macan uses the Audi tranny

Exactly. I don't quite understand how the Macan could downshift without rev matching if it's a PDK, unless it's just griding the clutch to bring the engine up to speed. There's no viscous coupling or torque converter to allow any slip otherwise.

The Audi and Porsche DCT’s are both made by ZF. The 981 uses the 7DT-45, the Macan uses a variant of that, the 7DT-75, which I assume has a higher torque rating.

As others have said, your Macan is definitely rev matching downshifts, just maybe not as aggressively as your Cayman does. If it wasn't, it'd feel like you were slamming the brakes every time you pulled the paddle as drivetrain hauls the engine up to speed.

PDK query, any difference in internal operation with console shifter vs paddles?
i mean besides the likely quicker flick of the paddle?

There is no diff.
They are just different switches that send the same signal to the same place.
I use both routinely.

Does not "blip" the throttle
