"SUV" should mean an off-road capable vehicle or something that can tow a decent amount. Maybe had a body-on-frame construction. Usually larger and less pleasant on-road manners. Usually has a transfer case. A Tahoe, Expedition, Dodge Durango, Wagoneer. Those are all firmly in the SUV territory in my book.
Everything else should be called a "crossover". Less off-road capable. Less towing. Not saying they couldn't do these tasks, but not as much. Usually unibody construction. Usually smaller. More street-focused.
Obviously there is some overlap, and neither term is strictly defined, but not sure why this is so complicated.
I'm more bothered by how this dilutes the "Mustang" moniker. Why they'd do that with their most iconic car I'm not sure. Might as well make a "Mustang M150" truck now too.
Porsche IS the brand. It's customers thought the Macan would tarnish the brand. But in reality they needed the Macan to keep making other models. Same situation as Lambo, Aston, Lotus and soon to be McClaren.
I don't buy into the "we HAD TO in order to stay afloat" mantra all of the performance makers are using to justify SUVs. It's a lie. They sell tons of cars at absurd prices. What they meant was "Investors said we had to because there was more money to be made."
