Macan is definitely too small. Cayenne is a great tow vehicle by European standards and a decent one by American standards, but at only 7700 lbs rating it's still not really built for towing.
I prefer SUVs over pickups for towing for a variety of reasons, but when I got my new travel trailer, it's just a little too heavy for the 1/2 ton options out there. The problem is, the car manufacturers stopped making 3/4 ton SUVs. So now the Ford Expedition gets to the highest tow rating you can get on a modern SUV, at around 9200 lbs, which still isn't enough for my purposes, plus the Expedition is kind of ugly.
So that's how I ended up with the F150 supercrew with max towing, it'll do 11,500 lbs. It's not truly a 3/4 ton but it's also more than a 1/2 ton, I guess it's a 2/3 ton or something. Anyway, with its twin turbo V6 gas engine it's a great daily driver, but also has incredible torque throughout the power band which makes towing even very heavy trailers, a real pleasure.
