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.

Better soundproofed, more powerful, and feels more like a continuation of my hands and feet when driving — in other words, you feel like a single unit during the driving experience — but cramped for me at 6 ft 1 in to get in and out…
