 I am a month in to owning the Q60S Red Sport 400.  I have owned BMWs (740i, 540i & M5) & Audis (S4 Cabrio and S5 Coupe) in the past as comparison. The exterior appearance is stunning. Like truly breathtaking. I find myself walking backwards away from the car so I can look at it more. The interior design is very well done. The front seats are magic. Just outstanding from a comfort & lateral stability standpoint. Engine performance can be described as a giggle machine with a start button. Just mash the throttle and laugh. The 400bhp & 350ft/lb of torque are available from 2500 RPMs all the way to redline. My favorite move is when I am on the open freeway & impatiently slogging along behind some snow bird doing 55 in a 65 zone. I lightly tug the downshift paddle twice to take me to 5th gear and bury the boot. Good lord, the acceleration is instant and fantastic! Within a few seconds I am doing 100MPH and rushing quickly towards 120MPH if I'm not careful. I've had the car up to 125MPH so far and the stability & smoothness inspires a ton of confidence. The car just seems to sit down on its haunches the faster you go. I set the "Personal" mode on the Infiniti Drive Mode to "Sport+" engine with "Standard" steering and suspension.  This gives me the truest GT experience with instant throttle response & a nice, soft, cushy ride. If I know I will be on the twisties, I'll choose "Sport+" mode across the board. The Bose sound system is hands-down the best sounding system I've heard in any car. I know, I know. No highs, no lows, it's gotta be a Bose. That may have been true five years ago, but this system, in this particular car is brilliant. So perfectly clean, with large bass response (no annoying rattle) and crisp highs that just sing. Maybe the Mark Levinson system in the Lexus LS600H is better, but then you're paying $120k for a sedan, so... Handling is so good to the point where it's annoying. I cannot seem to get the car to oversteer or understeer. It just corners with complete neutrality. If I turn off the dynamic anti-skid nannies I could probably get the car to slide some, but I am reticent to do that until I have a better feel for the 16lb/ft of turbo boost coming from the twin chargers. You don't want to get into a slide and have your turbos kick in before the apex! Braking is strong and linear. I adapted to the brakes the first day, which is a testament to how well -- and predictably -- they stop. The car comes with so much safety technology, you almost have to be an imbecile to get into a wreck. I'm sure I can personally figure out a way, as I lean towards the imbecilic, but truly, any normal person is safer in this car than in Fort Knox. Ok, now for the less than stellar. First, the steering. The DAS steering is as vague as everyone says it is. It's really designed and set up for long trips where comfort and low-fatigue are more important than feeling connected to the car. I wish there was a way to turn it off. Shift response is inconsistent. Downshifts under light acceleration come when they feel like it. Downshifts under hard acceleration come fairly quickly, but if you've ever driven a Porsche with the PDK dual clutch, the Q60 Red Sport ain't even in the same universe. Again, you're paying less than half the price, so... Still, for $62k, you'd think a less awesome dual clutch auto-trans would be mated to this terrific engine. As lovely as the interior is, I have a few nits. There are some very specific areas where the materials chosen are just plain cheap AF. The lower part of the interior door assembly for example. Cheap plastic. The inside of the glove box, center console storage and cigarette lighter opening... The cheapest felt-like substance known to man. Like those 1970s glow-in-the-dark posters with the black fuzzy crap? Yeah, that stuff (they still make that shizz?). The rocker switch for the aforementioned Infiniti Drive Mode, and the Audi-like circular mouse control are made of hollow chromed plastic that don't feel stout when you're pulling, pushing or twisting them. Guys, really? Use real aluminum for these things for goodness sakes! We have seat heat and steering wheel heat, but we do not have seat ventilation/cooling. This is a big deal to me because I live in Phoenix, AZ. I almost didn't buy the car because of this. Infiniti offers seat ventilation on many of their other models -- as do Honda, Toyota, Ford, Chevy, Opel, Kia and Hyundai. I love these seats, but I won't have a sexual relationship with them until they have ventilation. Lastly, the exhaust note. There really isn't one. When you first start the car, there is slight growl that seems promising but once the engine speed dies down to idle, the car is almost as quiet as a Tesla. If you put the car in "Sport+" mode, Infiniti figured out a way to pump some exhaust noise into the cabin to remind you that you have hair on your chest, but it's just not aggressive or loud enough. I'm sitting on 400HP baby! Remind me!
