Wow. A lot to unpack there.
Let's start with the tires/AWD lazy theme. I am speaking from 40 years of driving experience that includes international driving experience. I have never owned an AWD vehicle, I do own a 4WD vehicle, it is a very rare occasion that I feel the need to shift into 4WD HI to drive in winter. Of the 5 vehicles I have owned in that time period, I have NEVER owned a set of dedicated snow tires, I have NEVER gotten stuck or had a sliding accident due to my skills or lack of and poor road conditions. I live in W PA, we can get lake effect or Nor'easter storms that dump feet of snow in my area. Travel to work is 50 miles, into the snow belt north of I80. If you drive within your means, have decent all season tires that have some siping on them, you will do just fine. No real need for snow tires with a FWD or AWD. My 4WD Xterra had Kumho all seasons until about 2 years ago when I went to a deep lugged Cooper tire with new wheels. Prior to that, no need for winter tires. If a person feels it is absolutely necessary to have a dedicated snow tire to be out in the snow, have at it. In my world, not necessary. If it is that bad out, you have no business being on the road. Get out of the way and let the plow crews do their job that my tax dollars are paying to do.
No comment except I've seen some crazy icec/snow videos out of Russia showing CX5's.
Power plant. I am a little leary of owning a 4 cylinder SUV like the CX5. When I consider what I'll be using the vehicle for (to and from work about 85% of the time and then general running around locally) it would be nice if Mazda put more horses into the engine, I would not complain. I was hoping that that my next vehicle would have a minimum 250hp, that would mean Forester, never warmed up to the Subaru. So the CX5 has a 187hp motor with a six speed auto. Since it appears as though the tranny and the engine output are a good match, the perception is that you have more power than you actually do and it can get you up to highway speed quick enough. Also being able to slap stick it and downshift to get the engine some relief is a plus, you just have to learn to work the combination. The Molester has a 6 and not a CX5. Why he keeps showing up in the CX5 forum to talk about his 6 is beyond me, other than his 6 is underpowered and he is here to complain about it? I was all set to buy a Sport Sedan, my criteria was AWD, minimum 275hp. Love the current 6 styling, and that is where it ends. Dog motor in a FWD sedan. Had it been RWD, I might reconsider. But the 6 is all teeth and no bite in my world where I want a Sport Sedan that has power and looks. The Mazda 6 is usually a "slow as balls but it felt so good to drive" car in reviews. Don't let anyone wiht a sub-200hp car run their suck about speed unless it's also sub 2000#. As to the CX5, it actually does better in the real world AND on paper than its numbers indicate, not that it's fast, but it is adequate.
Lastly size and space. It is good to have and not use than to need and not have. I live alone, no kids to haul etc. When I go to work, I use up about 60% of the rear cargo space in my Xterra for my work kit. I have to judiciously pack the MX5 to get everything into it for work. If I go to the range or fly fishing, I have a lot of stuff to carry and I use the Xterra for that. It has 125K on it, I am concerned for it's long term reliability. The CX5 is it's successor. A 6 sedan would have worked except it has the dog engine in it. I was all set to buy a Ford Fusion Sport with AWD, 325hp V6 twin turbo, would have bought a $400 tune reflash to boost to 400hp and had a lot of fun. Sale price and depreciation killed the deal. See, I want power in a Sport Sedan, not so much of a big deal in a SUV/CUV. The Xterra is a heavier vehicle than the CX5 yet has less HP than the CX5, so when it comes to the 99% of the type of driving I do (paved roads) the Xterra experience has been more than adequate and the CX5 should be also due to it being lighter and more HP. I am in the same boat as you, but man, I have used the space in my CX5. That said, I would have been better off with a Jeep Grand Cherokee sized vehicle 10% of the time. Again though, that came with a very high fuel cost for that slight bit of added utility.
Lastly, Molester does not own or drive a CX5 on a regular basis, so I have no idea where his fantasy CX5 driving experience comes from. He reads facts and figures and watches videos, yet has no relevant experience to draw from when it comes to the CX5. Yet just can't help himself to stop posting in the CX5 forum with 6 comparisons.
