Does the Hero 3+ switch on/off on connection to a power supply?
I want to use it to record car racing and this would be a very useful feature.
If not, is there a GoPro model with this feature?

The HERO3+ can be configured to automatically power OFF after a specific period of inactivity (when no Videos or Photos are being taken and no buttons have been pressed) -- go to Set Up > Manual Power Off. However, the camera doesn't have the auto power ON feature.
When using the HERO7 Black and HERO6 Black camera, you can use Voice Control to turn on the camera for up to 8 hours after the camera has been turned off. Voice Control must be enabled and you must also turn on the option "Wake on Voice."
The GoPro camera will work normally when powered from an external power source 5V 1A (5V 2A recommended for HERO7 Black, Silver and White, HERO6 Black, Fusion, HERO5 Black and HERO5 Session) via USB-C cable.
In addition to this, I suggest removing the battery if you will be using the camera for very long-term shooting (e.g. Timelapse) to prevent the camera from overheating – at some point, preventing potential damage to the battery as well. Other users have expressed similar suggestion when using external power source for continuous recording.
On a side note, without the battery installed, the camera will eventually turn off the moment that the external power stops.

Hi Ann, thanks a lot, this really helps!
Are there any GoPro models that do have an auto power ON feature? (Not voice controlled or with WiFi remote that is..)

This feature is weirdly missing from every single gopro model. I too went through the search and fortunately there are solutions. I complained years ago to gopro support as did others if you search around, and it's fallen on deaf ears.
GoPro Hero 3 white and black could be used with the Camdo Time Lapse Intervalometer (setting 1001) to auto power on. I do this myself and have an autoexec script on the sd card to turn on the wifi, which enables me to connect a gopro remote that I have in the car to start/stop recording. Very important to stop the recording before power is lost. I also provide 12V power from the car via Camdo's battery eliminator.
Bad news is Camdo discontinued these models that work with the Hero 3 white/black. I know because I broke my intervalometer and went searching, but fortunately for me by dumb luck caught a fellow selling one on Ebay which saved my day.
Some good news is that with a Hero 5 black (and I'm sure later models but I can only personally confirm this works on the hero 5 black) you can do similar things with Camdo's newer Blinkx. It's undocumented but the Blinkx with a specific setting (which I'm forgetting at this moment, I think set one of the schedules to the lowest 1 min interval and to turn the camera on) when power is provided to the blinkx it will shortly after power up the gopro (it varies from like 5 seconds to a minute, due to how often it sends the power on signal which happens once a minute on its timer). The Blinkx will also provide power, but you need a 12V to 5V micro usb converter which you can get off ebay for less than $3. There is some bad news though. The blinkx is crazy expensive more than a camera, like around $355 at the moment I think. Also, I've found it not to be 100% reliable as sometimes the camera goes into a "bad" state where it just doesn't want to turn on and the only fix is to disconnect it from the blinkx and put in a charged battery and then power on the gopro which seems to "fix" things for a while (it's usually weeks to months before this issue manifests for me). Oh, and with the blinkx you don't need to have a battery in the camera. Also no need/use for an autoexec script for turning on wifi because the hero 5 has that option built-in.
