The Kia EV9 is a bold, boxy electric SUV that looks like it could swallow your luggage and the in‑laws, with an interior that feels more lounge than cockpit and a presence that makes smaller rivals suddenly feel shy. On the road it delivers calm long‑distance composure with enough shove to keep overtakes effortless, and its tech and practicality make it an easy, sensible choice for buyers who want electric without compromise.

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.
