The styling is going to be divisive. A combination of almost exaggeratedly voluptuous curves and starkly plain elements do not marry well to my eye. The lines made the car appear lower to the ground than it is and wider, but unfortunately also emphasized the fact this is a big car. It looks every bit of its length with both front and rear fascia that stretch. In stretching the rear roofline, Mazda made the unfortunate choice to add a piece of black plastic rather than a window or to change the read door windows to cover the space. The one thing I will say for it is that it does not strike me as any other car.
Going to the interior, I can see where they tried to make it appear upscale and premium. However, while there was more equipment and it was fancier, I found it more stodgy than classy or luxurious. Touring and Grand Touring trim lines have panels finished in a grey and black stripe that reminds of little more than some of the 70's wall paneling in the house I grew up in. The dash was also black on the GT model I drove with an otherwise tan interior, which did not work well aesthetically. Were the materials better or was the fit and finish better? Some materials definitely were, though I would say the fit and finish was about the same (no complaints with either) Overall, the controls worked well, though the steering wheel controls for audio and cruise functions are significantly smaller than on the 1st gen, and the rocker switches less user friendly than the earlier design. While I had limited experience with the audio system, I would say it is a little better than the Bose on the 1st gen, and the beeps can now be turned off from the audio menu.
The driving position is quite good, assisted by the 8 way power driver's seat, and a turn knob for lumbar rather than the useless lever on earlier models. Large mirrors and easy visibility out the car meant I did not need to test the Blind Spot Warning System. I will agree the seat leather has been upgraded, but the seat shape put an unfortunate top bolster that dug into my shoulders. Head room was also very tight under the moonroof for the driver (6'2"), tighter than on my 5 door by a fraction. While a power passenger seat is a welcome addition, they neglected to include a height adjustment, making the new 6 yet another car I cannot fit into the passenger seat. A plastic cover for the frame VIN is also annoyingly in the passenger footwell. Rear seat leg room was the most notable increase in the new car, but unfortunately the swept roofline makes headroom at a premium, making the rear seat no more comfortable for me than a 1st gen sedan. The rear seat itself was nicely shaped and supportive and exit and entry was easy from all doors.
The trunk is large, with a flat floor, and the pass through when the seat is folded is about normal size. However, one of the more annoying cost cutting moves was the seats no longer fold in one operation. The handles have also been downgraded to nylon loops. Other unfortunate penny pinching includes the visor vanity mirrors now are only lit from one side rather than both (a light above would have been a less noticeable way to save a light), and the center console. While the armrest slides back and forth (though useless because it is too low), there is only one level with a removable tray rather than the two separate levels in ours. Interior storage has also been diminished by the loss of the dash top bin.
One note: the auto-up windows passed the fist test. I put my fist (pinky down) in the window channel and activate the auto-up window. The window reversed effectively and kept the forces low enough not to hurt the hand. For those who commented on the first gen 6, the lockout button still locks out the driver's controls.
OK, so enough of the look/touch/feel... how did they drive? I started with the I4 model, and found the power decent, but of course not what I'm used to with a V6 MTX. While I prefer more power, I was able to chirp the 1-2 shift on an onramp and never felt I was lacking for power. The MTX unit shifted nicely, but it felt less connected and mechanical than I like, and the small rounded shift knob did not fit well to the hand. Shifts throws are short and sure and the clutch works well, though is light. On the V6, I could definitely feel the power, but it was hard for me to compare actual acceleration to my car as it is so isolated. Noise elimination is taken to extremes on both models, but particularly with the eerie silence of the V6 model. The shifts were undetectable with the 6 speed unit whether I shifted or let it. There is a serious lack of engine and exhaust music from either powertrain.
The ride is well controlled, however, the softness serves to isolate and insulate the driver away from the driving experience rather than draw the driver into it. Stodgy is also an apt description of the car's handling. While it took what I threw at it, and body lean was controlled, there was no spirit to it. There is a large dead zone where the steering center should be that detracted from the total experience and the nimbleness. The car feels its size on winding roads, though very competent. The tire selection is the same Pilot HX MXM4's that plagued the 1st generation Mazda6, so a decent set of tires may help some handling elements, though I fear the dead spot steering is not one of them. In tighter maneuvers, I did not notice the smaller turning circle, and the speed sensitive steering is seamless. Mazda claims it's a little heavier than the 1st generation, but I could not feel it. The gauges were a sporting aspect, but I would rather have seen the gauges as a clustered panel rather than individual tunnels. An overly busy LED display attempts to display odometer, trip odometer, and outside temperature. It was also unfortunate that using the trip computer eliminates the clock from the center display.
Overall, the car didn't just grow up and become more roomy and luxurious, but it grew old too. It's fancier, more equipped, more powerful, in some ways roomier, but it also lost its Zoom Zoom along the way. I would not consider this a sports sedan or even a sporty sedan anymore. Name it a Mercury Milan, style it to those cues where needed, and it would fit right in and be an appropriate product. It does not fit to the brand Mazda has built over the last several years.
