Model Overview:

With its line of S models, Audi has built a reputation for delivering understated luxury along with a healthy dose of performance. Supporting the foundation of this reputation is the Audi S4, which is a sportier variant of the already-proficient A4 entry-level luxury sedan. As such, both of these Audis benefit from handsome styling, excellent interior design and materials, cosseting comfort and superior road-holding thanks to all-wheel-drive traction.

Where the S4 and A4 differ is in performance. Throughout its run, the S4 has boasted higher power output, sharper handling and impressive braking capabilities. Shoppers seeking a used S4 may, depending on the model year, have several body styles from which to choose. On the downside, the S4 has typically lacked the crisp handling performance offered by some of its rivals. Overall, though, we hold the Audi S4 in high regard.

Current Audi S4
Unlike previous generations, the current fifth-generation Audi S4 is only available as a sedan. The convertible version has been replaced by the S5 Cabriolet. The S4 is powered by a supercharged 3.0-liter V6 that produces 333 horsepower and 325 pound-feet of torque. A standard six-speed manual or optional seven-speed dual-clutch automated manual (S tronic) sends power to Audi's rear-biased "Quattro" all-wheel-drive system.

Inside, you'll find (in true Audi tradition) one of the finest cabins in the sport sedan class. The overall design is demure but classy, and although the center console is rather button-happy, Audi's updated MMI electronics interface is now much friendlier to use than before. The seats are supremely comfortable in the front, offering plenty of support through corners and over distances. Like the A4, the S4 offers a reasonably large backseat should your sport sedan be called on for family duty.

The S4 comes with an ample list of standard luxury features like xenon headlights, selectable driving settings (known as Audi Drive Select), tri-zone climate control and leather/faux-suede upholstery. Upgrades include bigger wheels, an adaptive suspension, a rear limited-slip differential, keyless ignition and entry, navigation and a premium Bang & Olufsen stereo.

The S4 shines thanks to its strong supercharged V6, sharp handling and a forgiving nature made possible by Quattro and that optional limited-slip rear differential. Even driven aggressively, the S4 imparts confidence to the driver. Grip is tenacious and the chassis is communicative. Even so, ride comfort is commendable and cabin noise is pleasantly hushed.

Used Audi S4 Models
The current Audi S4 represents the fifth generation in the model's lineage, debuting in 2010. An optional rearview camera and blind-spot warning system were made available the following year. For 2013, the S4 received a slight styling update (with more angular grille/headlights) and a revised MMI control interface. That year also saw the switch to electric-assisted steering. Apart from lacking Audi Drive Select as standard (it was optional though), these latter S4s are similar to today's version.

The previous, fourth-generation Audi S4 was available in a variety of body styles. The sedan and wagon (Avant) were sold from 2006-'08, while the convertible (cabriolet) lasted from 2007-'09. Relative to third-generation S4s, the fourth generation offered refreshed styling, a revised chassis and a more sport-biased Quattro system, though these changes represented more of a revitalization effort rather than a complete redesign.

Under this S4's hood was a 4.2-liter V8 that generated 340 hp and 302 lb-ft of torque. Power was sent to the Quattro all-wheel-drive system through either a six-speed manual transmission or a six-speed automatic. As with today's S4, this generation model had additional performance-oriented modifications, including a sport-tuned suspension, 18-inch wheels with high-performance tires and more powerful brakes.

Inside, front occupants were treated to a comfortable and functional cockpit. The backseat was more cramped than in the current car, and the electronics systems may seem a bit dated now. The electronics interface, in particular, could be quite frustrating to use with the optional navigation system installed. Leather seating was standard, and interior trim, lighting and controls were all of high quality.

The similar third-generation S4 was offered for 2004 and '05. This was the model that introduced the 340-hp V8 engine and expanded S4 availability to the sedan, wagon and convertible body styles. As with the fourth-gen S4, transmission choices were either a six-speed manual or a six-speed automatic. At the time, the installation of such a powerful V8 in a small car raised some eyebrows, and indeed it boasted more power than BMW's contemporary M3 or Mercedes' C32.

In reviews of the third- and fourth-generation S4, we commented favorably about the car's broad power band, multiple body styles and high-quality interior. Downsides were a cramped backseat and handling that wasn't as razor-sharp as the M3's. The fact that the current S4 no longer has the V8 engine should make these generations a more novel, collectible choice in coming years.

Previous to these newer S4s, there were two other generations of the Audi S4 -- a second-generation vehicle, available from the 2000-'02 model years, and a first generation, available from 1992-'94.

The second-generation model was based on the A4 sedan and wagon of its day, and it came equipped with a twin-turbo 2.7-liter V6 engine rated at 250 hp. Quattro was standard, and Audi offered either a six-speed manual transmission or a five-speed automatic. In Edmunds' S4 road tests at the time, we found the car very enjoyable to drive, as it struck an ideal balance between outright performance and everyday comfort. Our main complaint about this model was the familiar lack of rear-seat room.

The first-generation Audi S4 was a performance variant of the Audi 100 sedan (later A6) sold from 1992-'94. These S4s came with a turbocharged inline five-cylinder engine capable of 227 hp. Quattro was again standard, and these cars were equipped with a five-speed manual transmission only. After 1994, they became known as the S6. First-generation S4s are a relatively rare find today.

  • The best overall car I have ever owned - 2001 Audi S4
    By -

    This car is absolutely perfect. Though My wife made me opt for the tiptronic rather than the 6 speed, this car is still a blast to drive. You can really feel the autobahn engineering. It gives you a planted feel regardless of speed or driving conditions. I ski 15 to 20 times a winter and I have never had a problem taking this up the mountain. Quattro is excellent in the snow. Before this I had a Mercedes ML320 SUV, and I would take the audi any day. No regrets on my purchase. The biggest problem that I have had is that the stereo stopped working and had to be replaced, and I understand that this is a common issue in these cars.

    I love the sound and performance of the big V8. The AWD has been impressive in the snow and on ice. It can still get stuck if the snow is deep enough, and the traction control system is complex. Audi does not provide good information on it. The ride is on the harsh side, and not adjustable. There have been transient squeaks and rattles from the interior body panels. The rear seat is cramped. Aside from all this, the car is very quick, handles well and is a blast to drive. Navigation and audio system both excellent, and I like the iPod integration even though the track names do not show up on the screen

  • Love my car - 2005 Audi S4
    By -

    I have to say that I really love this car. I now have 35K miles on it and it is as good as the day I bought it. When I purchased it, there wasnt an RS4 yet. Otherwise I would have bought that. But at this price point, I think it is one of the best cars in the world. Due to inclement weather I sold my previous sports cars, a BMW M3 and a Mazda RX8. While the BMW was spectacular, it just didnt work in the snow. At all. The RX8 was a dud all around. It was fun to shift, but that was it. It was slow, could not be driven in snow, and it stalled and needed to be towed constantly. The s4 is quick, handles great in snow, & is a perfect wolf in sheeps clothing. I highly recommend it.

  • One of my best purchases - 2014 Audi S4
    By -

    Was on the fence between the S4 and the 335i, and boy am I glad I got the Audi. Ive had the car for 2 years, and this is a short summary of what Ive learned. Ill go straight to the point and point out the bad first. Transmission: can get clunky; when you pop it into Drive, its response is laggy Handling: my previous Genesis coupe felt more confident-inspiring in the corners MMI: I prefer the MB Command or the Porsche interface Thats pretty much all the cons that I can think of. The car accelerates as well as any 3.0L Scharged sport sedan will go. Brakes are fantastic with a consistent feel. The seats are not plush, but wont give you any issues. Drove from FL to NY and did not feel too bad. Build quality is top notch. My brother has the F30 328xi and the Audi feels more sturdy.

  • Excellent Car - 2000 Audi S4
    By -

    I just purchased this beautiful car through a private sale, 180000 kms. The car is still as beautiful as the day it was made, everything works perfect. Great power and amazing handling. I love the interior design but there might be a bit too many buttons. Looks really good with aftermarket Pirelli tires and 18inch rims. Overall this car is a 10/10 for me. Hope you enjoy yours as much!

  • 2018 vs 2010 Audi S4 Prestige - 2018 Audi S4
    By -

    After much cross shopping, including the Mercedes C43 AMG, I ended up replacing my 2010 Audi S4 Prestige (7A) with a relatively loaded 2018 (S- Sport and winter packages, 19" wheels, Dynamic Steering). Ive only had it for one week so this just my first impression, which is mixed. Whats better in the 2018 S4: suspension (more compliant with no loss of grip); brakes (less grabby with no loss of stopping power); steering (still lacks feel but quicker and more accurate, particularly off center); front seat adjustability; instrument panel; parking & driver aids; headlights; fuel economy. Whats better on the 2010 S4: exterior styling (except the lights); throttle response; transmission (DCT); difference in driving experience in different mode settings (comfort, auto, dynamic). It looks like the 2018 wins by a knockout but it doesnt. The new car is really let down by a tendency to bog on initial throttle application. It feels like some combination of poor transmission tuning, a very soft throttle tip-in setup, and some degree of turbo lag. It can be a party pooper and the car doesnt come alive in Dynamic mode they way the old one did. Well see if the 2018 S4 grows in on over time. Ive already discovered that using the paddle shifters helps with throttle response. Ive already shifted this car "manually" in one week more than I did in the old S4 over seven years. The ZF 8-speed in the new S4 responds pretty quickly to the paddles but doesnt cope well with stacked downshift requests. I read that the terrific new 10-speed auto in high performance Chevies drops multiple gears in an instant. More to follow once my new S4 passs the 1,000 mile break in period.

  • Best Car - Even if its Thirsty - 2005 Audi S4
    By -

    By far the best car Ive ever owned, and Ive had a bunch. Drives like a four door Porsche C4. I get bored quickly with cars, but every time I get in the S4 it feels like Ive been given a gift. If you are a car enthusiast, you simply cant have a bad time in this car. You pay for the V-8 when you fill up (you can use regular, though), but youre more than equally rewarded when you step on the accelerator.

  • Love my S4 - 2001 Audi S4
    By -

    This car is fun to drive, plenty of acceleration. Great in the snow, and better than expected MPG for a V6 Turbo.

  • Love it!! - 2005 Audi S4
    By -

    I have had my S4 Convertible for about a year and a half and love it! I cant tell you how many people have commented on my "cool car". The car is insane around corners and I have beaten Porche Boxters on regular occasions in "races". The car almost keeps up with my business partners BMW M3. I have an automatic and there is a little "lag time" when you step on the gas, but once it gets moving, it moves like crazy!

  • S4 Avant - A car to love - 2004 Audi S4
    By -

    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.
