Review of the 2004 Audi A6

  • Solid performance and an elegant cabin design make the A6 a worthy competitor in the luxury sedan class, but BMW's 5 Series is more athletic and Mercedes carries more brand cachet, so it can't be called a class leader just yet.

  • Safety
  • Pros

    Heavenly cabin furnishings, varied menu of engines, all-wheel-drive utility.

  • Cons

    Nonlinear steering, limited availability of manual transmission.

  • What's New for 2004

    A sport mode is added to the "multitronic" CVT, the center console's retractable cup holder is replaced by a power point and all quattro models now come standard with a sunroof.

Phenomenal car

Vehicle: 2004 Audi A6 2.7T S-Line quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)

Bought the '04 S-line in Sept '09 with 55k miles on it. Mint condition for 15k. Could not be happier! added APR chip to get HP to 310 and it really makes a difference. Used to have 3 series BMW and this blows it away. Build quality is so much better. best vehicle i've ever driven in foul weather (snow, rain). Very safe feeling in all situations. One thing i learned is Dealers will kill you on repairs. got to find an indy tech. watch out for the cam adjuster seal leak' DLR scam. they claim its $1200 in labor. only takes them 2 hrs! find an independent mechanic or get warranty. wonderful car. had not problems at 72k miles yet.

This is the best piece of man made machine I have ever driven. I drove Infiniti G35's and Nissan 350Z and then had two hondas and one gm. Of all those cars, I can say this is in its own category and nothing comes to close to the performance and comfort and style and OH YOU HAVE A NICE CAR comments. MY next car will be an A8L but I will enjoy every bit of my A6. Every time I start the engine and hear the muffler noise (modified) I just cant wait to hit on the gas pedal and accelerate. The feel is way beyond anything I can ever own and AFFORD to own. 20k$

I'm the 2nd owner off lease. I've been driving it for 2 years now. First couple of months the car was stock and throttle response a bit dead. I had the ECU chipped and it really livened it up. Plus gas mileage is a couple per gallon better (not great about 20 MPG combined city / hwy). I've tinted the windows and added aftermarket wheels to the otherwise boring design of the 18" S- Line stockers. Oil lines to the turbos were updated for 2004 so no more blown turbos (one goes you've got to replace the other)! Ride is very nice and not too harsh. S-Line A6 2.7t's aren't on every corner so you feel like you're in a more exclusive club. Love the car...luxury and sportiness all in one!




Luxury & sport for 20k

If you're dumb enough to buy a $50k car and complain that it costs a lot to maintain (when you only paid 20k for it) then shame on you. This is a phenomenal car and beats the pants off any comparable, or even brand new, car you can get for ~20k. I've had 2 and loved them both. (148k miles, and 22k miles) The car is fast, comfortable, reliable (if you keep it up), and an awesome daily driver.




Another great audi product.

Vehicle: 2004 Audi A6 2.7T S-Line quattro AWD 4dr Sedan (2.7L 6cyl Turbo 5A)

We were needing to get something a little larger than our A4. I looked at Caddys, Jags, Beemers, Mercs and Inf. There was always something about them that made them either feel very dated on the inside (Jag, Merc, BMW) or cheap on the inside (Inf, Caddy). When I first looked at the A6 I looked at the 3.0 CVT model, but heard many negs about the CVT. Decided to risk the turbos and step up to the 2.7T S-Line as it wasn't much more money on the used market. I am so pleased with my decision. The car is beautiful inside and out. It performs great in all conditions. Decent fuel economy. I haven't loved a car as much as this one since my 1993 & 97 Infiniti J30. And this car blows em away.




Extra performance is easy!

This is a great car for any family. The added bonus (for dad or mom) is the easy modification. I have added a GIAC perfromance chip, cold air intake and better turbo valves. This car easily outruns a Mustang GT in the straight line and on the track. It is fun to pass so-called "sports cars" with my son's car-seat in the back.
