2017 S6 Prestige Mythos black, Cold weather, handling package, driver assistance, black optic pkg. I shopped around at BMW (550xi), Maserati (Ghibli), Mercedes (E400), and Jaguar before making my decision on the 2017 Audi S6. In comparison no other car felt as athletic, well grounded, and luxurious all in the same package as the S6. The S6 is awesome, by far the most enjoyable Audi i have ever drove or owned. I am looking for reasons to take it out (grocery store, pick up fast food, run errands, etc). The engine gives you massive hp and torque at low rpms, and the exhaust note is intoxicating, but is not overstated. The S6 has plenty of room for both front and rear passengers, and has lots of tech upgrades such as bose audio system, apple car play, google based navigation, and tons of safety features. With configurable settings for ride height, transmission, and suspension the car can go from stiff and sporty, to comfort and luxurious for longer drives. I love this car!

Imagine spending 70k for a car and being glad you did. For the money, I think you would be hard pressed to beat the quality, functionality, and performance of this vehicle. The exterior is modest but handsome and understates what lies within. Most non-car people don't have any idea what this car is about. For me, that is appealing. I read all the reviews and most were spot on. The only downside is having to constantly watch your speed (although there is an alarm for that), as the car demands to be driven fast. Running errands is no longer a chore. If you are considering this vehicle and need something luxurious, practical, and a thrill to drive, buy it as the possibility of buyer's remorse is non-existent. This car won't let you down.

Great car, horrendous repairs and maintenance

I purchased this car with approximately 40,000 miles on it and by 60,000 it needed over $4,000 dollars in repairs. At 50,000 miles the "check coolant" message appeared every day until a visit to the dealer revealed that a new water pump was needed at around $2,000 with labor. Not 5,000 miles later the engine developed a high pitch squeal at idle. The remedy for that was a costly repair to the high pressure oil system. Throughout the ownership of the car a clunking noise could be heard from the passenger footwell over every bump. This was never actually solved but was believed to be the front drive shaft and was replaced. Granted the dealership sympathized with me over the problems I was having and had Audi cover the cost. The adaptive cruise control went out of calibration several times and disabled the cruise until a $400 calibration was completed. Besides from the mechanical issues several interior rattles showed up in quick succession. Maintenance costs were as expected for oil changes but in order to perform the 75,000 mile service the entire front end would have had to be disassembled adding up to a $2,000 plus charge. All that aside the car itself was fantastic. The engine sounded rich and the acceleration was insane. The interior looked premium and the quilted seats were gorgeous. The exterior of the car had just the right blend of sport and luxury. All in all the dealer was exceptional and I would recommend the car if you don't mind the high maintenance and repair costs.

This car is worth every dollar... and you will pay for the privilege. Extremely comfortable, fast, quiet inside, great exhaust note on the outside. Fully adjustable steering, transmission, engine response, exhaust volume, wonderful stereo. This thing is built like a tank, but dances like a ballerina. The unaware would be very unwise to challenge you at the stoplight. Update - Even more impressed on long road trips and handling in the snow, including almost 30mpg at 70mph. Continues to be supremely fast, comfortable and capable.

It is true this car doesn't handle as well as other in it's class and price range. With that said, 99% of most drivers (me included) don't drive on the track and don't reach the limits of this car or any other in it's class. And then you enjoy the comforts of a grown up car, while having ample power and fun. For me, I couldn't think of another car to own.

It was tough getting my hands on one of theses guys. I didn't even see one to test drive before i picked mine up. When i finally did I had absolutely none of the buyers remorse that often come with forking over 80+K for a car. From the way the car starts and revs when you press the classy res start button, to the diamond leather stitching inside the car is a true gem. The controls , especially for media and music have a learning cuvre, but the touchpad and nav are truly top class. I opted for the black optic package and 20 inch wheels which give the car a bit of an edge not seen on the basic model, and I recommend payimg for the extended 10 yr warrant as I can only image what this puppy will cost later on t o fix, but this being my 3rd audi, I know I wont have much to worry about until year 10 and beyond. The car is a dream to drive, and I love flexing its muscle to the unsuspecting speed racer nob heads you often encounter on the road. Car came with summer tires so i immediately got the snow tire package and am actually begging for snow. The car has tremendous grip on snow , as most audi's with quattro do. Basically I love my new car, and inncidentlly it looks better then the slightly more expensive s7 in my opinion.

My first Audi, and definitely not my last! Similar to anyone else looking at this beast of a car, I checked at BMW and MB. Although all 3 were great in their own right, I REALLY liked how Audi brought the fun to drive aspect of the BMW together with the luxury of the Benz. It's not as flashy as either one of its competitors, but that's something I like. It's understated elegance is perfect for me and anyone else who wants to drive an amazing car that doesn't say "I'm trying to keep up with the Joneses". Car enthusiast know what you're driving but the average person just thinks you got a clean, elegant looking and nice sounding sedan. Some of my favorite features are the massaging seats (many variations of messaging available), 14 speaker - 630 watt Bose sound system, infotainment system (once you figure it out), options on ambient lighting, Google maps (the best!), Apple Car Play, USB connections (finally), clean exterior lines, gorgeous interior styling, acceleration (off the charts), and finally driving and handling ability! If I had to give a gripe (and I have a couple), the gas mileage can be really bad if you're not careful and the noise level on highway speeds is higher than I would have liked (It's about the same as the others in it's segment, I'm just used to an SUV and it seemed quite because your higher off the road....I guess). Keep up the good work Audi, you knocked this one out of the park!

I have leased the 2016 S6 and just passed the 15K mile threshold. The car performs largely as advertised. Accelleration is steady and very powerful, continues to build way past any speed at which I am comfortable to drive (and way past any highway speed limits). The dual clutch transmission is also smooth and fast, though driving with one takes a little getting used to, particularly when changing from reverse to drive or at low speeds. The sedan is also quite nimble for its size, and with the active suspension it has very little body roll. In particular, it is a pleasure to accelerate through and out of turns, let the torque vector push the car around the bends. The interior is very quiet and comfortable, and the comfort seat package IMHO is great (I think ventilated seats are a must in a warm climate). My only gripe is that the touchpad system is terrible. Audi uses it for radio presets, and it will often mistake a touch for an attempt at setting a new preset, causing you to have to go back and re-input your intended stations. I just don't use it at all for anything but navigation entry (the handwriting recognition is good). The audio quality is solid (I didn't choose the top-level system, just the upgraded sound). Fuel economy is about what you'd expect for a car of this type, and I average about 22mpg in mixed driving. Overall, if you want a beautiful, understated but very fast, very luxurious sedan, this is a great choice, and I'd get it again.

I traded my 2011 Audi S4 Prestige with drive Select on a 2013 S6 with the invovation package. Although the S6 was 30% more expensive than the S4, I consider it a bargain. It rides better, handles better, is faster, and is techincally much more advanced than the S4. It also gets just as good gas mileage. I have been driving Audi Quattros since 1987 and This is my eleventh one, so I do have considerable experience with the brand and know what I am saying when I say the 2013 Audi S6 is one awesome car.

Overall very good car with excellent drive train, decent fuel economy, good handling for big car, and thus far above average reliability. Very good MMI information system. Downside, sport seats are hard, so consider buying with comfort seat. 20 inch wheels looks great but ride and noise level are affected so go with 19 inch wheels.

Bought a 2016 Audi S6 pre-owned. So far I could not be more happy with the comfort, technology, power and sound of this engine. Its only been 2 weeks. Ok-Maybe it is a bit early. I have owned Acura TL, Acura RL Infinity G37S, mazda 6, Honda Accord, and a Benz SEC500 and long ago a 1969 GTO. My last car which I still own is an Acura RL. I thought this car was amazing. Perhaps it still is. However my Audi S6 is incredible a far more advancement in my driving world. With excellent care I hope to write more positive reviews In the future.

My wife rules the frequency of my car purchases, so I wanted to be sure I would enjoy this car for a while. Have owned it a year and a half now and I am still intoxicated by the daily driving experience! The Sport pkg is well worth it, giving the handling and exhaust note vast improvements over base systems. B&O sound system is astounding! This car is so planted in all driving situations i have encountered...just wow! Love it!! This one's a keeper!!

I have owned over 40 cars including BMWs, Lexuses and Porsches. I must say this Audi S6 is my favorite car hands down other than a Porsche Turbo 911 but it is easier to get in and out of. Faster and more comfortable than most cars I have owned. It is a pleasure to drive again. And the interior is gorgeous.

Traded a '15 Porsche Panamera for 2017 with 32K miles. I have no criticisms of this Audi (my first). Fit, finish, performance, handling, and, oh my acceleration (think of the pedal as more of a trigger). The MMI system is easy to use and the Carplay (my first time for this) is quite good as well. There is some road noise but with 20" wheels and summer performance tires what would you expect? The standard Bose radio is probably the worst feature in a car with an original MSRP of $82K. I don't know why any manufacturer at this price point does not put in top of the line sound systems. The exhaust note could be better/more accurate than what is "pumped in" to the cabin (but it still sounds pretty good). This car has 150hp more than the Panamera I had and all the technology do-dads you want (brake assist; adaptive cruise; lane change departure warning). The Porsche, with an original list of $96K had none of these. I know those are optional on each car but one, at $82K list, had them and one, at $96K list, did not. The interior is every bit as nice if not nicer than the Porsche. The gas mileage is what I expected with a 450hp twin turbo V-8 (averaging about 22 between city/highway). You do not buy this car for mpg; you buy it for pulling the trigger and experiencing 4500 lbs. move like shot out of a cannon (had handle pretty well too). The suspension (air) does have differing feels between comfort and sport settings and I like the cutomizable individual as well. So, 5 stars so far. The only "defect" I have found was a small, loose piece of rubber trunk molding (Automotive Goop fixed this) and the plastic around the inside rear view mirror was not fitting right (prying it to clip correctly fixed this issue).
Quick, sporty, and comfortable.

Purchased used in mid 2024 with 70,000kms. I've owned a 2016 GT V8 Mustang and 2014 Holden Calais V 6.0L (tuned and modified). The Audi is absolutely beautiful to drive. Perhaps the only car I've driven for 8hrs for fun across a section of our beautiful country NZ. The Audi turns heads especially in Sepang Blue with the black trim package. I've also installed 2020 RS style 20" wheels because the Audi Rotor wheels are an older design. Driving the car it has enough power and torque for highways and mountain passes. I'd like a little more power for track days but a dyno tune will gain another 100hp so that's an easy fix. I mention track days but I'm really referring to track cruises as this is not a race car. My last 2016 RSQ3 Performance was awesome but this is next level. Higher luxury inside and more tuning features. My model has heated rear seats also, a nice touch. Would buy another one if this was damaged in a heartbeat.
