Overview & Reviews

The all-new S4 sports some serious hardware, not the least of which is a 4.2-liter V8 bristling with 340 horsepower. A convertible body style has been added to the lineup.

• Broad power band, fast and confident in the turns, high-quality materials and attractive cabin design.

  AWD Rocket - 2004 Audi S4
  By anchorage - May 10 - 1:22 pm

  2004 Audi S4 Manual 26K miles Im 6 250 lbs Male What a blast to drive. I bought this low mile beauty above market and it was a joy to drive. Both it the city where I absolutely rocketed between stoplights and in the city where I flew around curves the Audi never stopped delighting me. I had the manual (which is why I had to sell it after only 2K miles due to a bad knee) which I imagine is more fun. It stuck to the road like it was glued. I never really drove it in the winter so the AWD was only tested in rain - it worked great. Absolutely a joy to drive unless stuck in traffic. I could not make myself go slow unless I was trapped in traffic. I replaced it with a Pontiac G8 GT.

  Buy with warranty or be ready to spend - 2004 Audi S4
  By AC_SOCAL - May 5 - 5:41 pm

  Pros : Performance is awesome, one of the best looking sport sedans , interior is spacious, sound system is great, fully loaded with options, very nice seats. Cons: 1) very poor reliability! So far : bearings, engine cover gaskets, coils, light sensors, seat warmers wiring, clutch!, control arm. I was not expecting that many issues with a car that I take good care of and I hardly overdrive it! Good thing all were covered by extended warranty. 2) MPG : 14 to 15 3) Front heavy due to engine weight I am reluctant to buy another Audi, although the S5 is hard to resist. I owned 328i BWM for 5 yrs I did not have any problems until around 100K miles,I started having problems with S4 at 30K mi

  Fairly Impressed - 2004 Audi S4
  By Proud Dad - March 24 - 12:53 pm

  Was looking for a 4 door with some grunt...domestics (Charger, Impala, etc) were garbage. S4 head and shoulders above. This car gets after it. Seats are extremely supportive and engine growl is addicting. Hugs the road and begs for curves. Dont know if I would recommend for a commuter car. Made more for crooked back roads. Best looking car on road in my opinion and its 5 years old at this point! Averaging around 19 combined mpg--and thats with me "going easy" on acceleration and driving a lot of interstate. Like I said, not necessarily a commuter car or a car thats going to attract a lot of attention (a good thing in my book!).

  The perfect all around car - 2004 Audi S4
  By Joe - September 28 - 11:52 am

  I bought this car as a Audi CPO and only had it a few months but this is the car for me! By far the fastest car I ever owned! Not flashy yet very stylish and gives you the best all around performance. I can pick up my kid from school, plow threw snow and rain, yet take a Porsche Boxster! You start to smile as soon as you start this car up. The rumble of the V-8 is just amazing but it still is quite and refined when you drive at high speeds. The AWD not only helps in the snow but but makes the handling unbelieveable. Even if this car loses grib it quickly corrects itself and keeps you in control. this is my first Audi so I just hope it is reliable because I want to keep it for a long time

  Supercar in a sedan! - 2004 Audi S4
  By jpez - July 14 - 2:40 pm

  I just bought this car as a certified pre-owned. So far I love the car! It is so fast and comfortable to drive! All the luxury I can ever need and fast enough to keep up with most of the sports cars on the road. All with all wheel drive and 4 doors! I can take my daughter to school in it, go through bad weather or run it at the track. This car was made for a family guy like myself who doesnt want to let go of the kid in them!

  Fun car to own and drive - 2004 Audi S4
  By Nick - April 9 - 3:46 pm

  Car is an everyday car with performance, although a bit heavy. Glad I bought it and has been worth it so far. No major repairs needed as with the other reviewers and Im just under 30k miles and put 6k on when I bought it used. Have run it through snow, sleet, and rain and it hasnt failed me yet! I would recommend this car if youve got income to spend on it snacking on fuel every opportunity it can get.

  S4 Avant - A car to love - 2004 Audi S4
  By S4AudiAvantAdvocate - October 5 - 3:44 pm

  Purchased my S4 Avant in July 07. Most enjoyable car I have owned. It has utility but is refined and comfortable, the design and styling of the B6 model S4 is timeless. The handling is incredible and effortless despite a 2 ton curb weight, 4 doors, a fully functional rear seat and a large wagon cargo area. My fuel economy has averaged 17.8. I have gotten as high as 21 in highway only driving. Not as bad as others suggest, but certainly no economy or hybrid. The acceleration certainly provides a more than adequate trade off. The rear seat is comfortable for average adult passengers. Not as spacious as a full size (A6/8, 5/7series) but the other options dont provide a V8 6 spd manual.

  Great looker - very poor reliability - 2004 Audi S4
  By Stephen Williams - January 8 - 4:19 pm

  This is my second S4 (I had a 2001 previously), and my 5th Audi. The design is great, interior elegant and ergonomic, and it performs great. But the reliability has been miserable. I only kept it for 6 months - it was in the shop every month of those 6 months. It went through brake rotors, had a coolant leak, an transmission cooler leak, the ABS system failed intermittently, and the check engine light came on (bad O2 sensors) twice. Probably the last Audi Ill ever buy - sad really.

  Incredible Car! Buy Certified! - 2004 Audi S4
  By MrLiou168 - December 10 - 10:40 am

  Went from E36 M3 to M Roadster to B5 S4 to E46 M3, and now this B6 S4. What a difference! The V8 is a torque monster compared to the M cars, and handling is every bit as sharp and confidence-inspiring. Interior cant be beat, and Bose stereo works well. I think Audis nav system has a contract with the oil companies, as this thing will re-route you all over the country. Passing power is awesome, but clutch engagement is very tricky. Highly recommended, as long as you dont live in a city. City MPG is between 9-13! The fun factor is worth every gallon however.

  Audi S4 - Hard to Beat! - 2004 Audi S4
  By audimania - August 6 - 11:59 am

  Leased silver sedan with automatic trans in October 2003. Car has 35,000 miles. It is truly a drivers car - on windy, country roads, it handles as well as my Porsche 911. The handling is superior as are the brakes and ride quality. Reliability has been a bit of an issue - transmission had to be replaced - would have cost in excess of $6500 if car had not been under warranty. In short, if you can accept the extremely mediocre gas mileage, and want to carry 4 in relative comfort, and you want a smile on your face every time you drive, this is the machine.
