It is true, the performance of the engine depends on the version of the software - manufacturer declares that this engine with this software can achieve this maximum performance and the software can't be legally nad officially tuned or changed. Btw in my country tax depends on engine displacement so it doesn't really change anything.
In most countries I know of (almost all of western EU), for electrical vehicles, you have to register the real maximum power output by the engine. If a software update allows you to increase that over the registered power, then you are in violation of motor vehicle codes and would need to a) pay a fine b) then update the registration, which is usually a $$$ process.
If, like TFA, they register the power output as larger than the actual one in order to give room to these "unlocks", then you basically have a vehicle which can do less than what its registration says, which people tend to notice and riot about (you pay more taxes and insurance).
In which country does the tax rate depend still only on volume?
You know that you can tune your engine right? And this is done with software that does ECU tuning. So in theory all cars are illegal?
The issue is not that you can do it, the issue (as stated in the VW article) is how to update your car papers to reflect the changes. You do it illegally with your friends? You can't. VW does it through the subscription? (I guess) allowed.
Don't ask me how, but when you buy such cars (with an engine that can support multiple configuration), you won't register your engine for something it is not. It's what's enabled to do. Simple example: you buy the ford ecoboost 1.0 100HPs. It won't be registered as the 150HPs model, although it's 100% the same hardware.

You know that you CANNOT tune your engine, without going through your state's motor vehicle department, right ??
If the manufacturer tunes the ECU via whatever method and as consequence lowers/raises the power, good for him, but the final maximum power number is what will appear on the registration, and only in case of huge negligence can he change it afterwards on sold cars.

As I have repeated in literally each one of the 3 messages I have written in this thread: TFA clearly says the register the car for the maximum unlocked power level. Which means you _are literally paying for the maximum power even if you don't unlock it_, in terms of insurance and tax.
> you buy the ford ecoboost 1.0 100HPs. It won't be registered as the 150HPs model, although it's 100% the same hardware.
That's unsourced bullshit. I'm not familiar with Ford US cars, but Wikipedia clearly lists that the different models _are differently sized_.
But, even if it was true, and software was used as in the interlock mechanism, Ford would have to register these engines as with their maximum, unlocked power, and that's something people tend to notice.
