I was lucky enough to sit in the new Infiniti Q60 and the interior is looks and feels amazing! It was the Red S 3.0t variant with white leather interior and it's just built to be a luxurious yet sporty car.
Apologies for the potato quality but I tried my best. As you can see from the first pictures, the seats were designed like pods, very comfortable pods that will make you feel like you're sitting on a cloud. The head rest was tilted forward a bit but it wasn't as intrusive as I originally thought, was actually very comfortable and it could potentially fix my poor posture if I sit in it long enough since it made me sit a bit straighter.
Unfortunately, I couldn't fully move the front seat forward to give the back seats a try. Maybe I wasn't pulling or pushing hard enough but if the front seat is any indication, the rear passenger seats should be just as comfortable and I managed to take a picture from the front. It looks almost identical to the concept interior except for the lack of diamond stitching but that is negligible. The seat itself looks a bit more sunken in than the average car but that just means you'll be very well seated and not shifting around during tight turns. The middle has two cup holders and a flat area that's not as deep for random objects. Also of note are the baby seat locks which are easily accessible.
The center console is clean and sleek with a nice carbon fiber border and the dash was soft to the touch with very nice stitching.
That carbon fiber theme and white leather can be found on the doors too. What's interesting is that there's a handle in the driver side. Instead of the traditional hole in the door for drivers to grab hold of in order to close the door, you get a nice curved and leather wrapped door handle.
Of course, no luxury car is complete without a leather wrapped steering wheel. Very clean and the buttons look well placed with the more commonly used ones placed on the outside; volume control, return button, etc. Nice looking speedometer too with a silver border that's not just a plain circle.
Now I'm more excited than ever for the new Infiniti Q60.
