How does comfort of the three models compare? I’m talking about current generations.
In particular, as someone 186cm tall, I find Corolla hatch not very comfortable, especially for longer distances. It’s just impossible to find a comfortable position behind the steering wheel. Either the wheel is too far or pedals too close.
Other things I’m curious about is visibility and noise level at highway speeds in those three models.
The newest CX-5 model years will perform best in terms of ride comfort and NVH. The torsion beam rear suspension on the Mazda3 and CX-30 somewhat compromises the compliance over bumpy surfaces, whereas the CX-5 retains independent rear suspension. I also find the 3 and CX-30 a bit cramped and I’m not a large/tall guy.
The one spot where the 3 and CX-30 easily outclass the CX-5 is in seat comfort though. The CX-5 seat materials and supportiveness are fine, but the shape and size are really annoying. There’s minimal side bolstering and it feels like your ass is sinking into a cushy bowl when driving.
At the end of the day, your best option is to test drive all three as much as possible and trust your instincts.
