I've heard the start/stop feature is automatically turned off once you get into Sport+ or Race mode, but are there other means to disable it permanently so it doesn't keep reengaging requiring a manual turn off? I hate auto start/stop and on an earlier 911 I had all that was required was a button to turn it off and it'd never turn itself back on unless you manually disengaged.

Because that is how alot of them make the mandatory Carbon emission estimates and desires. On and Off is more wear and tear on the starting system, regardless of how little it is needed. It's another PIA little gain/return item to make them look "like they give 2 poops"-That's why most MFG do it-

Back on topic-
Good info on cooling on this thread. Have had similar questions myself for a while now. In the past I made a point to turn off start/stop if my temps were on the higher end (>210F). I probably still will but good to know cooling is still occurring when the engine stops.

I do, and there's nothing wrong with it. Comfort mode is designed for around town driving. I don't use Sport at all, other than the Sport suspension setting in Individual mode. My Individual mode is essentially S+, but with the suspension in Sport and transmission in M. It's my highway and open road mode. I drive 90+% in manual mode. I only let the transmission shift automatically in Comfort. In all other modes I'm in M, so my Comfort mode has adapted to my casual moderate driving style, and for more spirited driving I shift myself. In the canyons I'm in Race mode and M. Each mode does have its purpose, but I haven't found much use for the Sport mode.

LOL! I think most people need to learn how to shift themselves to get the most out of the car. The biggest difference in the modes are the shift programs, but if you shift yourself there isn't much difference between C and S+ in terms of response. The shifts are a bit more violent in S+ and M and the initial throttle response is a bit sharper, but the rest is up to the driver. Really the main reason I change modes is for AMG DYNAMICS and the suspension to get better handling when I'm tossing it around corners, or driving at higher speeds.

What are you talking about? Rev matching is automatic. I'm not talking about a downshift. Have you ever actually done a full throttle manual upshift in S+ vs. C. You get a kick in the back in S+, whereas in C the upshift is mostly smooth even under full throttle, at least with the 9-MCT. No need to call me names. I'm not driving like an idiot around town with pedestrians around, that's partly why I'm in C in those situations. Give me an open road, canyon or a track and we can talk. Rest is wannabe racer talk.

Hey I'm not saying there's anything wrong with it but your last sentence is exactly how I feel about comfort mode. Granted I'm in a PFL but the transmission is entirely to laggy in comfort, not to mention that it starts out in 2nd rather than 1st. Sport to me is what comfort should've been from the factory. Once my car is warm I'm straight to individual mode which for me is comfort susp, race eng, sport + exhaust. When it's time to have fun it's sport + or Race with paddles.

That makes a lot of sense now. Didn't realize @Scania123 has a PFL as well, so now I understand where he's coming from. The transmission is the weakest link in the PFL. I've said this before. Some people who have briefly test driven a FL don't seem to think so, but it really is once you lived with it for a while. The manual mode of the 9-MCT is essentially night and day once the car is broken in compared to the laggy manual mode of the 7-MCT, and in automatic mode it always starts in 1st gear for a much better off the line response. The first 7 gears are also shorter, so the whole drivetrain feels more alive. I totally agree with you. Comfort mode in the PFL is terrible. That 2nd gear start is horrendous. It's just slipping the clutch and I have to wonder what that does to the clutch wear. The FL is actually responsive in Comfort mode. It does upshift early if you are lazy on the throttle, and it shifts a lot for fuel efficiency, but you can control that behavior pretty well with the throttle. I had a 2013 Audi RS5 before with a dual-clutch transmission, and the FL feels more responsive in Comfort than my RS5 did in Dynamic. The FL always seems to be in the right gear for the most part, and starts downshifting proactively when slowing down to be ready to accelerate out again. BTW, the FL also doesn't glide anymore in Comfort mode like the PFL does with ECO start/stop turned on.

But the turbos are cooled by engine coolant, and those coolant circuits have auxiliary electric pumps that can run with the engine stopped or after you turn the car off to keep the turbos at a reasonable temp. Because of this, the oil in the stationary turbos never gets hot enough to bake off, which is the old school reason for letting an engine idle down for a little after driving, because you didn't have coolant in there and had to rely on the fresh oil supply to moderate turbo temperature.
)?I generally let the car idle for a bit & drive timidly before shutting the car off.
