> Porsche buyers know that 'Turbo' means

As a car guy, I strongly disagree. In the car world, nearly without exception, including all previously Porches, "Turbo" is a label indicating that a specific piece of hardware is installed on the ICE: a turbocharger.

This is like putting a "manual" or "automatic" label on an electric. Sure, you could probably consider an electric a manual 1 speed or automatic 1 speed, but it's not going to get anything but marketing BS eye rolls from anyone that knows about cars.

It feels like more a branding term with ICE Porsche too ever since they've started putting turbochargers on the non-Turbo-branded versions too.

Fair enough, but you won't find a "Turbo" labelled ICE, Porsche or anything else, without an actual turbocharger.

Exactly! As an owner of a Turbocharged ICE sports car (EVO X) I can say that turbocharger(s) in a car gives it some very specific characteristics (namely a specific torque curve to the engine) which differentiates it from a non-turbocharged vehicle. The turbocharger compresses the input charge and is driven by the exhaust gases. If companies start labelling non-turbocharged vehicles as Turbo, it's a complete mis-representation and a faux-pas in my opinion. Porsche has simply got it wrong here.
