2014 1st REVIEW - I am now on my third Audi and my current S4 is certainly the best. I test drove all models excluding A8 (can't afford it anyway) and S4 drives the best. Especially in its Sport mode - what a thrill! You can make it a normal commute car and join thousands of other generics on the highway during rush hours. But you can put in more aggressive mode and enjoy a proper sports car at a press of a button (well several buttons anyway). Brilliant design, excellent engineering and great execution. ----- 2017 2nd REVIEW - My first review (see above) was written 3+ years ago. Well now I owned this car for 3.5 years. It is an excellent driver's car indeed. Engine is simply superb, smart technology and very thoughtful quality accents are everywhere, car software is perfect. It still drives like a dream. I am very happy with my purchase. Love the quality and reliability, love the intelligence and absolutely love the speed and acceleration. No breakdowns whatsoever in 3.5 years and 56K miles. However maintenance cost is way too high if you don't do it yourself. I decided to do as much as possible myself (I like working on my cars) and after some initial investment in required tools my son and I already changed oil, breaks, disks, sparks plugs, filters, etc - everything strictly according to the maintenance schedule and AUDI torque specs. We use only OEM parts and save about 60-70% compared to our local dealership price. We also had to buy a special cable to re-program the car, reset service reminder, etc. I actually love working on this AUDI, it is very well engineered and it is a pleasure to service it. There is one more thing to know / consider. You should not expect this car to be very economical fuel consumption-wise. It all depends on how you drive it - you can get anywhere from 15 to 28 MPG on a highway. Once you floor it, your MPG drops - but the thrill is very well worth it. Highly recommended to those who like quality, sophistication, reliability, technology and speed. This S4 delivers all of that. Good job AUDI! 2019 3rd REVIEW - I now have almost 85K miles on the odometer. Still truly enjoy driving my S4 every time I am behind the wheel. Superb, high quality and very reliable car. Very fast, very sporty and responsive. My car still looks like new and I am not going to get a new one any time soon. I always precisely follow recommended service schedule (everything by the book!) and so far I had no problems except for one issue. At around 70K miles I started smelling gas around the vehicle. I run diagnostics and it showed misfire error code in one of the cylinders. The problem was fixed by replacing all 6 ignition coils - I did everything myself in about 20 min. After some on-line research I found that this seems to be a well-known issue - my suggestion would be to replace all coils every 60K miles. Otherwise no problems whatsoever. 2021 4th REVIEW - so far so very good. No issues, scheduled maintenance only. Recently had a road trip across the country, car performed very well and was large enough for comfortable all-day driving. It is now 100K miles + on my odometer. End of 2022 5th REVIEW - after noticing some minor noises coming out of front suspension at around 105K miles, I changed suspension components in the front myself, properly following original Audi service manual - took me three days but everything was done 100% accurately and carefully using original parts and new bolts and nuts. I had PCV-related code when I diagnosed the car recently, but the code was “unconfirmed” so I just cleared it and it did not show again next time I read the codes. I don’t drive it much these days, but when I do I am still very happy with the car. All maintenance is done according to the schedule, hopefully that will make it last 200K and beyond. The car is already 9 years old but still looks like new!

The S4 does everything well. It is very quick, handles well, and brakes well. After approximately 11,000 mi. (in a year and a half) it is holding up well, and it still looks sharp. The miles are low because our summer drive is a Porsche Cayman S. The S4 is about as quick in a straight line, but it can't compare to the Porsche's road-holding. (Part of the difference lies in tires.) At nearly 14,000 miles, we still feel this is a great car. The supercharged V6 is a delight, and the transmission works well with it. 'No problems to report. Update: After another 4,000 miles, we still think this is a great car. 'Will buy another in a year or two if they didn't mess up the V6. Update: At nearly 20,000 mi., we still think this is a great car. No problems to report. Highway mpg is in the 32-34 range.

Everything you want in a 6M sport sedan

If you are looking for well engineered sport sedan, super fun to drive, classy not flashy, comfortable, and, most importantly for me, with a 6M, this is your car. Let me just get the transmission issue out of the way right now. I don't know why people would get an automatic in a car like the S4. You're buying a Camry, Impala, or whatever, sure, go with an automatic, who cares, but an Audi with V6 supercharged engine? The whole point of a car like the S4 is to have some fun, but then you get an automatic with it and you're saying, "actually, I want to reduce the fun I have with this car." What? Anyway, whatever, just my bias. Okay, to the car itself -- what a marvelous vehicle. I did a lot of research on cars in this range, test drove a few, and knew this was the one I wanted. It took me nearly a year to find a used one in the right color (grey), black optic package (just for the wheels, don't care about extras), with the 6M, and the right price, but when I found it online, I jumped and bought it used with 12K miles and hope to keep it a long time. Engine and transmission: fantastic, best transmission I've ever driven, engine sounds great, power is there all day long at whatever speed you want. Spectacular. Some people (mainly auto critics) complain about not enough "feedback" from the steering. I don't know any better and the steering feels great to me. This car sticks to the road. I put Conti ExtremeContact DWS on a few months ago. They are not quite as sticky as the summer tires that were on, but the very marginal loss of performance in turns is more than offset by the superb all weather capability. With the Contis and quattro, I am ready for any ice and snow or rain. Interior and exterior are beautiful, not flashy, very sophisticated. That's what I wanted. If you want to show off, get some attention, you may need to look at another car. Tech: these are my only nits. As noted in reviews, the MMI control knob spins in a non-intuitive direction. Why? I have no idea. The MMI interface is good, not great, but good. Love the dash display, all the options. Climate control is my least favorite feature. It works, but it is too complicated, too many buttons. I am still not 100% positive what I am ending up with when I make certain adjustments. I can live with it. The S4 comes with so many other helpful electronic features that I highly recommend you go through the manual page by page to make sure you are aware of them all. (For example, you can set the passenger side mirror to tilt down when you back up. Never would have known that.) You can adjust suspension, engine sound, etc. In sum, this is a wonderful car. There are other possibilities in this price/performance range, but I can't imagine anyone ever regretting the S4. (especially with the 6M transmission!)

Great car overall. Excellent driving experience. Plenty of power. High quality conservative interior. Perfect B&O audio system. Reliable. For those of us who like to service their cars, I would advise to do the following beyond standard service procedures (which still need to be precisely followed). Invest in VAG-COM cable and do car diagnostics yourself. Use only original AUDI parts. Replace all ignition coil packs (~$160 parts) when you put new spark plugs at 55K miles (in my car at 65K miles one ignition coli pack gave up and I had a "cylinder misfire" code). Replace your break fluid every two years. Rotate your wheels every 5K miles. Replace brake rotors at the same time when you replace your brake pads. Clean and condition your leather seats and door inserts (if any) at least every 6 months. Wipe your interior plastic with high-quality non-glossy plastic cleaning/conditioning fluid at least every 3 months. Clean and lube your sunroof (two different tubes required) as per schedule. In cold climates condition rubber door insulation before every winter. Never change oil using retraction method (it leaves lots of old oil inside), do it the "old way". Maintain 37 psi in front tires and 33 psi in rear with up to 2 people in the car. Maintain 41 psi in all tires with full load; adjust the pressure every time you rotate your wheels / change your load.

One of my best purchases

Was on the fence between the S4 and the 335i, and boy am I glad I got the Audi. I've had the car for 2 years, and this is a short summary of what I've learned. I'll 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 That's pretty much all the cons that I can think of. The car accelerates as well as any 3.0L S'charged sport sedan will go. Brakes are fantastic with a consistent feel. The seats are not plush, but won't 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.
