I am usually in Sport mode and when I push the button, the PDK drops at least 1 gear and the car feels like it is ready to handle business. That said, I don’t know that when I am actually ready to “handle business,” a few seconds after pushing the button, the car’s performance is any different than if I stayed in Sport mode and just went to heavy acceleration when I ready to go. In that situation the PDK seems to almost instantly say “I get it, here’s the right gear for what your right foot is telling me you want the car to do.” Maybe the sport response button is second faster than just mashing the accelerator.
I’ve driven my car ~2K miles so maybe I don’t appreciate the button yet. I will say that in the 992.2, given that the button seems to not really enhance the performance of the vehicle much, I do not like the fact that it is red (unless it is paired with other red accents).

I have seen a MPH or 2 in doing 1/8 and 1/4 hits with the button.

It’s actually the opposite.
The Sport Response simply puts the engine and PDK in Sport+ mode for a defined period of time. So if you are already in Sport+, it does not make any difference.

It's the on ramp, clover leaf, and passing button. I use it regularly when getting on the highway and merging with traffic. Also when maneuvering through traffic at highway speeds.
Puts the car in the lowest reasonable gear and will hold it to redline. Throttle response is very quick and the suspension tightens. I like the shift programming the best in sport response as well. It's a nice feeling shift.
So yeah, I use it a lot because I bought the entire tachometer and it's one of the best ways to use the entire tachometer.
Have not used the entire speedometer yet.

IDK..but the results from that video suggest a quicker car with it pressed, over boost or not. Throttle house raced the 992s against a corvette and also noted an overboost function and a faster 1/4 mile time. Others have said it does nothing, so who knows. This issue has been debated a million times or two over the years and I don’t think there has ever been a quantitative data driven case made, other than some
Dragy times. So it continues until someone can read boost pressures off a non-tuned engine.

SRB is much more than 20 seconds of Sport+. The power and torque may not be higher than usual even at maximum throttle, but it is available immediately due to the preload. This is achieved by downshifting in PDK and thus increasing the engine speed, which raises the speed of the turbocharger due to the increased volume flow, which is then used to quickly build up boost pressure with the wastegate closed accordingly or activation of the VTG guide vanes. The ignition is then selected in such a way that there is no excess power at first, but once the accelerator is opened for overtaking maximum performance becomes immediately available. Boost pressure is maintained then during the 20 sec. period even when applying the brake pedal.

Dumb question: will my manual transmission 4S have this function?
