Mechanically the car is fairly well built, apart from the rear axle.
The air conditioning is effective and visibility is good, while the FR setup paired with the 18" wheels, in my view, hurts comfort — getting in and out can be awkward. Once on board, though, the seats are very comfortable. The infotainment is comprehensive, with a generously sized screen and full-link smartphone connectivity; the factory sat-nav does what it can, but obviously Maps is superior in every way.
All in all, a fun/sporty car that also winks at family life thanks to a roomy boot and modest fuel consumption.

The Mazda is a more elegant car, less cumbersome and, even though it’s also an SUV, it feels less like an SUV and more like a regular car. Besides having an interior that feels more "like a real car" and less "smartphone," the finishes are also superior and the dynamic behavior is better. The lower power is made up for by being about 100 kg lighter, a lower vehicle height (more aerodynamic efficiency), and a smoother drive thanks to a high-displacement, non-turbo engine. The equipment is very similar but the Mazda just has more "class." Prices are comparable with equal equipment, and the difference is size: the Tucson being 11 cm longer is noticeable, especially in the boot — the Mazda’s is fine, but the Tucson’s is cavernous. If you don’t actually need something that big, I recommend the Mazda.

Nice luxury car, although I'm not sure I find the oversized rims that attractive. On the other hand, I like the Mazda 3 better.
