2020 A6, Edmunds Review:
“The car remains the most fun to drive vehicle I’ve ever owned. The new MMI that appeared radical a year ago is now so familiar. I love the ability to toggle and change info on the screens. I couldn’t imagine going back to the old push knob that seems archaic without a touch screen…”
2018 and 2017 Audi A6
The 2018 and 2017 A6 models are the final installments of the fourth generation that began in 2012. These models boast excellent owner reviews and are both great picks.
They have roomy interiors, powerful engines, intuitive tech interfaces, and well-balanced handling.

2018 A6, Edmunds Review:
“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…”
2015 and 2014 Audi A6
The 2015 and 2014 A6 models offer a well-appointed interior, generous passenger space, and are available with powerful supercharged and diesel V6 engines.

2014 A6, Edmunds Review:
“This is my 3rd A6. I had a 2008 3.2 and then a 2011 3.0. This time I had to decide whether to spend the extra money to stay with the 3.0 engine or drop down to the 2.0. After test driving the 2.0 on local roads and the interstate highway I determined that it had plenty of power for my driving style… Power accelerating onto the highway was great and going up hills locally was fine. Transmission shifts very smoothly. I saved a lot of money dropping down to the 2.0 while maintaining all the other great Audi features that I had…”
2011, 2010, and 2009 Audi A6
The 2011, 2010, and 2009 A6 models are the final installments of the third generation.
These come in either wagon or sedan form and have nicely appointed interiors, all-wheel-drive, and fairly decent fuel economy.
The EPA claims that these model years can achieve 21 MPG for combined city and highway driving.

2011 A6, Edmunds Review:
“I have had cars that are more fun to drive (Honda S2000), larger sedans (Volvo S80), and even another Audi that I thought was my favorite car (A4 convertible), but none has been as completely the total package as this car. The A6, while a bit blah on the exterior, is nearly perfect from the inside. The cabin is roomy, the seats are comfortable, the electronics are helpful, and simple to use, and the fit and finish is fantastic…”
2004 Audi A6
The 2004 A6 marks the end of the second generation.
This high-end vehicle is praised for its upscale cabin, solid performance, variety of engine options, and Quatro all-wheel drive.
New for this model is a sport mode for the “multitronic” CVT and a standard sunroof for all Quattro variants.
- Edmunds: 4.8 / 5.0

2004 A6, Edmunds Review:
“I’ve driven ~40,000 miles since I bought it at ~67,000 miles. I’m 6’5″, and most other cars don’t fit me well. This car is comfortable, roomy, and has a nice, big trunk. I love the all wheel drive, especially in the winter. This car has been remarkably reliable for me…”
1997 Audi A6
The 1997 is the third and final first-gen A6 ever produced.
It may lack modern designs and tech, but is considered to be a gem because of its roomy interior, luxurious appointments, smooth ride, and sure-footed handling.
Despite the incoming second generation, Audi added the following:
- Quattro Value Package
- Selective Unlocking Capability
- Jacquard Cloth Upholstery
- New Colors: Tornado Red, Volcano Black Metallic, and Byzantine Metallic
Based on the EPA’s estimates, fuel efficiency can hit around 19 MPG for combined city and highway driving, which is definitely commendable for its time and segment.

1997 A6, Edmunds Review:
“This has been the best car I have ever owned. I live in NE Ohio in “snow belt” country, and the A6 eats snow and ice and slush as well as my F-250 4×4. I don’t get tired driving it, whether it’s my short commute or occasional multi-hour trip. Great ergonomics. I’m a car nut, and every time I think about buying a new car I hold it up to the A6 for comparability. Most are found wanting…”

After about 5 mins of driving, everything powered down in the vehicle. From the dashboard to the center instrument panel. Then after that, the car cut off.” – CarProblemZoo.com

While the airbag problem was acknowledged and multiple recall campaigns were initiated, owners of these models were left waiting for unreasonable periods of time.
“I have attempted to have the airbag recall repairs done many times over the last year, only to be told that they are waiting for parts at Audi of Rochester NY.

“After a lengthy period of time, the service manager reported a coolant leak in valve n82; coolant migrated into the harness and contaminated transmission control unit”
A number of owners also reported that the car would surge or accelerate on its own.
“After purchasing the car I began to notice that when I accelerated from a stop, the car always surged ahead after a fraction of a second.”
“I was entering my garage and the car kept accelerating. I slammed into my front wall doing lots of damage to the structures as well as to my body. My car was totaled.”
The 2012 and 2013 A6 models also experienced much of the same airbag-related issues that cursed the 2005 to 2008 models.

“Climate control and turn signals do not always work upon start-up unless the ignition key is “jiggled” into the correct position. Appears to be a recurring problem with these models.”
