I hear ya about 70mph. I don't think they really focus much on higher speeds for EPA estimates or even real-world economy since a higher percentage of drivers in the US will be at 70mph or below instead of 80-85mph. Obviously, there are areas in the US that get to those higher speeds as the norm, but they are less common than lower speeds.
I haven't noticed much hood shake or mirror shake unless I'm driving into gusty headwinds that the Midwest is known for. Both my 2007 Mazda3 and 2015 Mazda3 had a bit more hood shake, as did my Subaru Forester. I've started to realize that it's just common these days (old cars I've owned didn't have it).
This is literally the only vehicle I've had that didn't have a rock-steady hood. Even the fiberglass cowl hood that fit for crap on my 1988 Mustang GT was rock steady for crying out loud. No excuse for this shoddiness at any price point, really. Even if it's not "causing a problem".
I agree about some of the features of other manufacturers, such as Hyundai. While they offer more, I never liked the "flair" of Hyundai interior. Mazda is a nice cross-between a Subaru and something that is more featured. It's simplistic in nature, appealing to the eyes, and has enough features to not be boring. This aligns with their focus on the Mazda being a driver's car. This is also why Subaru tends to adopt a similar philosophy with their interiors, but they're too aggressive with it.
I am very pleased with the lay-out of my CX-5. It was designed with a driver in mind and not a magazine ad photo.
I also agree that everything is comfortable and in reach. I've had cars where this isn't the case, and it's nice that they focused on driver accessibility.
Yep!
Maybe I've just owned loud vehicles (*cough* Subaru *cough*), but I've found it to be very quiet. Sure, you can hear the road. My wife was surprised at how quiet it was compared to our Mazda3s and previous vehicles. Then again, we've also never owned or driven anything upscale. Ignorance is bliss.
It reminds me of my 370Z, although it's louder at highway speed. Definitely in the "sports car" territory for road noise in my experience!
I 100% agree with the AWD system. It is an excellent piece of work. I'd say it's close to an even match with the Forester's AWD system. That's saying a lot since Subaru tends to lead the industry with AWD.
I had XM in my Mazda3 Grand Touring. Never used it much, so can't really comment on it. I found the audio quality over Bluetooth or even the HD Radio to be higher quality though. Satellite radio just seems like a gimmick with everything else that is available. I also haven't had any glitchy tethers with my iPhone 6S. I'm not sure if the Bluetooth firmware is higher in the 2016.5, but that could influence it. My 2015 Subaru Forester was plagued by Bluetooth tethering issues.
I have not had nightmare tethering issues, but it's enough that it comes off as a crap option compared to XM/Sirius. I miss the user-friendliness and quality of my 2010 Jeep's NAV/Infotainment system.
The 2016.5 has NAV standard on the Touring model. It's not bad, but I find myself using Waze on my phone more. I can't think of another GPS available that can compete with Waze for traffic routing and such, so I don't fault the built-in GPS.
