To get the most out of this car

This car is amazing and if you want to get the best version of the C7 A6 you will need a 3.0T trim level that offers the sport suspension. With the V-6, Quattro and sport suspension package, the icing on this cake is the 19" wheels only because the 20" wheels create a harsh ride at times that you wouldn't notice with either the 18" or 19" wheels. The C7 seems to be the last A6 that has true exposed exhaust pipes and heat sinks. The Audi A6 has a "Launch Feature". A rarity for an ultra smooth riding luxury car. The car's handling and performance are so refined that you could never confuse the car for anything but true luxury. German luxury cars tend to be the best luxury cars IMO. This car drives more like a Mercedes vs. a BMW but it does have the mannerisms of both at times. It really is it's own car and the driving experience is user friendly and always enjoyable. It might be more expensive over other midsize luxury cars but other cheaper midsize luxury cars will be lacking in either high performance, handling or the highest quality materials. Not only does the A6 have all of this, it also has a silent cabin with an incredibly quiet engine to boot. Executive class at it's finest. If the overall reliability of this car is better than presumed, this could very well be the perfect car.

Love my A6 - If you're going to buy one, go all in

I've had guys who work at the dealership I bought my 2018 A6 remark that it's the nicest A6 they've seen. I bought the Prestige trim - 3.0T, driver assistance package, comfort seating package, and cold weather package - with florett silver metallic exterior and atlas beige (valcona) interior. I previously owned japanese cars - toyota or honda - that were progressively higher end trim as I got older and had more disposable income, but they were never luxury cars. I personally subscribe to the belief that if you're going to buy a luxury car, wait until you truly can afford it then get the higher end, where you notice and can enjoy the engine performance, higher end tech, interior quality etc. I still love driving my A6 almost a year into owning it. In this case with the 3.0T Prestige plus options, it was close to $70k, no doubt a high cost, but again, I waited quite some time and took care of other financial priorities first. In owning the A6 Prestige 3.0T plus options, I notice the drastic difference between my beautiful, powerful A6 and the less powerful, pedestrian quality materials on lesser A6 versions when I use a dealer loaner. BTW, there is an important warranty option - 10 years, 120,000 miles. At this cost, meaning the high relative cost of a fully decked out A6, compared with a few thousand more for this extensive warranty, I am surprised some choose not to buy this. It seemed like a no brainer to me.

Creamy ride

2.0 turbo with 19” 10 spoke wheels. Bought just a few weeks ago. I’ve had an Audi in the past and just had to come back. Something about the way an Audi drives just works for me. So far very happy with the ride. Seats comfortable, teenagers are happy in back, wife loves the look of the car. I drive the 3.0t, and it is a much more refined delivery of power than the 2.0t. But I kept another 7k in my pocket with the plenty capable 2.0t. Regarding engine note: no question a 4 banger is under the hood, but honestly it’s still a joy the drive. Quick around town and a bullet on the highway. Corners great - mileage is a little under what’s on the sticker for city driving and accurate for highway. I’m getting 18/30 rather than 22/31. But I’m still having fun with the right peddle:). Hard to keep it under 90mph on the highway - just so smooth and quiet. I like my music, and the upgraded Bose sound system delivers - no complaints. Pandora, Apple play all works well. Overall just a cool car, very happy with my choice.

A sporty sedan with wonderful safety & luxury

The supercharged engine in the 3.0 Prestige Quattro delivers powerful acceleration (0-60mph in just over 5 seconds), quietly and with excellent fuel economy (averaging 24mpg even with a lot of rush-hour stop-and-go driving). Its ride is smooth yet taut, with just a touch of stiffness noticeable when going over real bumps, but that's a quibble. On good highway it seems plush. Its all-wheel-drive and standard 18" wheel-and-tire package make it agile yet surprisingly serene and controlled. The tires are non-runflats, and there's a compact spare in the trunk. (Many high-end or sport models are equipped with 19" or even 20" wheels but I suggest avoiding them if you want a smooth ride. The look of large wheels is sporty but the 18" tires balance excellent ride and responsiveness, and are less expensive to replace.) You can also vary your setting the acceleration, steering weight, and suspension stiffness for "Comfort," "Dynamic," or "Automatic" (changing according to how aggressively you drive, which works well for my wife and me). Visibility is excellent, as are seat comfort and adjustability in the front. The back seat seems a bit lacking in thigh support to me (so I rated it just "OK" since it's not quite "Great"), but it's certainly spacious, and the Prestige comes with 3-zone rear climate controls and also (in ours, at least) a powered rear sunshade, which effectively reduces glare and discomfort in the summertime. There are also manual side-window shades. Heated seats are standard for the front but only an option for the rear, unfortunately not included in ours. However, I am normally up front either as a driver or passenger, and we did get the ventilated/air-conditioned seats there. These are great, with 3 levels of air speed (plus Off). Other things I like: The gear shift lever is basically mechanical, which I really prefer over the mostly "virtual" electronic shift lever on my BMW. The very spacious and well-finished trunk has automatic foot-waving open and pushbuttons for power close or close-and-lock. It has an elegant and good-size center screen for the parking cameras, menus, GPS navigation, etc. that slides out and tilts up almost like Mr. Sulu's weapons control system in Star Trek (and automatically retracts upon shutoff). In addition, there's a small area in the center of the dash between the speedo and tachometer that can also display nav maps/directions, radio controls, trip info, and other settings. The entertainment system includes a CD/DVD player with a built-in hard drive "jukebox" for up to about 15 CDs (plus SD card slots for adding more, but I think you have to use a PC to record those). The sound is excellent and the controls fairly intuitive, but one slight annoyance is its insistence on turning on the radio or CD (to your last source) whenever you restart the car or exit some other control. Also, the 360-degree or top-view cameras work great. The rear camera comes on automatically in reverse. However, the front camera has to be turned on manually by pushing a button instead of coming on automatically as it does in my BMW when pulling into the garage or approaching any parking barrier or curb, one reason I rated the system just "OK" and not "Great." But if I could I would actually rate it Very Good; the top view is clearer than in the BMW. Safety features are outstanding with the Prestige which has blind spot monitoring/warning (with lights and vibration of the steering wheel), front collision warning and automatic braking (that may have prevented an accident at least once) at medium to highway speeds, lane departure warning, and automatic cruise control with variable distance. All of these systems can also be switched off if you prefer, but they work well and are not so intrusive. The default distance control for auto cruise control is a little too cautious, causing it to brake the car when a passing car returns to my lane even with a reasonable distance, so I generally decide to reduce the response distance by at least 1 or 2 clicks. (But then when a car ahead really brakes, there's less room to react, so you might be in for a little "thrill" when it demonstrates the impressive braking capabilities of the A6.) I gave the navigation system only an "OK" rating rather than "Great" because the built-in system seems to be less savvy in finding addresses than BMW's, and it can be a bit frustrating to use if you aren't very practiced. But it has a handwriting recognition pad and the voice-input does indeed work if you know how to ask, so it's still really "Very Good." Also, I gave the Bluetooth system only an "OK" since it cannot connect to Apple CarPlay via Bluetooth, only via cable, whereas my '19 BMW has added that capability. But the Bluetooth does a fine job if you don't need CarPlay (and the built-in system may actually be preferable, especially with an up-to-date interface offered by the 2019 A6 or BMW). All of the preceding criticisms are really minor. Overall, it's a wonderful car.

Finally Found My Car!

I've owned and leased several different makes of cars & SUVs. The Audi A6 has been the best by far! I moved from a Q3 to the A6 for it's cargo space. It's very responsive, has great gas mileage, and handles wonderfully in the rain, ice & snow. The back support makes for a comfortable long drive. The only very small inconvenience I've noticed is that the front arm rest is too close to the cup holder, making larger cups impossible to fit. I would also recommend Alex at Audi Kirkwood as a sales brand specialist. He was honest, professional, EXTREMELY knowledgeable & patient during the entire process.
