Getting Your Audi A4 Quattro S Line to Feel Right
The Audi A4 Quattro S Line is a mid-size luxury sedan that has been around in various forms since the late 1990s. The current generation (B9 platform, refreshed as B9.5) uses a 2.0-liter turbocharged four-cylinder engine paired with Audi's quattro all-wheel-drive system. It is not the fastest car in its class, but it handles better than most people expect for a daily driver. The S Line trim adds sportier suspension tuning, larger wheels, and exterior styling elements that make it look more aggressive than a base A4. I have owned a 2020 A4 Quattro S Line for about three years now, and I can tell you that the driving experience is mostly good with a few quirks you need to know about upfront. The transmission is a 7-speed S tronic dual-clutch unit, which is smooth in normal driving but can jerk slightly when you are crawling in traffic. I learned this the hard way during my first month. I was stuck in a parking garage ramp, and the car would lurch forward every time I tried to creep. The workaround was simple: switch to manual mode and hold second gear. Once you do that, the clutch points become predictable and you can control the speed without the transmission fighting you.
The Ultimate Driving Experience Unveiling The Audi A4 Quattro S Line
The quattro system on this car is not the same as the old mechanical Torsen center differential you got in the older A4s. This one uses a multi-plate clutch that can send up to 70 percent of power to the front wheels when traction is normal, and shift bias rearward when slip is detected. In practice, this means the car feels planted in wet conditions, but it can also feel a bit detached on dry pavement because the system is so efficient at preventing wheel spin. You do not get the same sense of the rear wheels breaking loose that you might from a BMW 3 Series. The S Line suspension is firmer than the regular A4, which is what you want if you plan to drive this car on winding roads. The tradeoff is that you will feel every bump and crack in the road. I installed a set of Eibach Pro-Kit springs about 8,000 miles in to dial back the stiffness a little, and that improved the ride quality without ruining the handling. If you keep the stock suspension and drive on rough roads daily, your back will thank me later. The sport seats are also quite firm, which is fine for a few hours but can get uncomfortable on longer trips. One thing most people miss about the A4 Quattro S Line is the steering feel. Audi tuned it to be light at low speeds for parking and firmer at highway speeds, but it never really communicates much information to your hands. If you are coming from a car with more feedback, like an older BMW or Mazda, you will notice the difference immediately. The electronic power steering is calibrated for comfort and efficiency, not engagement. This is not necessarily a bad thing, but it is important to understand going in.
The engine produces 261 horsepower in the 45 TFSI version, which is adequate for merging and passing but not thrilling. The 0 to 60 time is around 5.6 seconds, which is quick enough for most situations. I have pushed this car harder than I probably should on a few back roads, and the chassis holds together well. The brakes are Bosch-made and provide good stopping power, though they can fade if you do repeated hard stops in a short period. Let them cool between runs if you are tracking the car. Fuel economy is about 24 mpg city and 31 mpg highway with the quattro system, which is reasonable for a car of this weight and power. The mild hybrid system (48-volt belt generator) helps with stop-start smoothness and provides a small boost during acceleration, but you will not notice a dramatic improvement in mileage. If fuel economy is your top priority, look at the A4 diesel version if your market has one, or consider a smaller front-wheel-drive model. The interior build quality is solid, with soft-touch materials on the dashboard and door panels. The virtual cockpit digital display is customizable and looks sharp, though it can be distracting if you spend too much time tweaking settings while driving. The MMI touch response system is intuitive once you get used to it, but the touchpad controller takes some getting over if you are coming from a car with a simpler interface. Physical buttons for climate control are still present, which is a relief.

Maintenance costs are higher than a Toyota Camry but in line with other German luxury sedans. An oil change with synthetic oil runs about $80 to $120 depending on where you go, and timing chain service on the 2.0 TFSI engine is not something you will need for a long time, but when it does come up, it is expensive. I recommend sticking with independent specialists who know these cars rather than the dealership, as the work is identical and the labor rates are usually lower. Parts are available through various sources, and many components are shared with other Volkswagen Group vehicles. Reliability is generally good for a modern German car, but there are a few known issues to watch for. The NGO valve in the 2.0 TFSI engine can clog over time, especially if you do a lot of short trips. I encountered this around 45,000 miles when I noticed a slight rough idle and a faint burning oil smell. The fix was an engine wash procedure and replacing the valve, which cost about $400 in parts and labor at my local shop. Adding a bottle of fuel system cleaner every few tanks helps prevent this from happening again. The S tronic transmission has its own set of considerations. The dual-clutch unit is fast and efficient, but it can develop shudder issues around 60,000 to 80,000 miles if the fluid has not been changed regularly. Audi recommends transmission fluid changes every 60,000 miles, but many owners report smoother operation when they do it at 40,000 miles. The fluid itself is a special low-viscosity type, so make sure whoever services your car uses the correct specification. Using the wrong fluid can cause premature wear and expensive repairs down the line.
Electronics can occasionally be finicky, particularly the keyless entry system and the parking sensors. I have had the car refuse to unlock with the key fob on a few occasions, usually in cold weather. The workaround is to hold the unlock button longer or use the physical key inside the fob. The parking assist system works well in open lots but can be confused by low walls or uneven surfaces. I usually turn it off in tight garages and rely on my own judgment. If you are considering this car, I would suggest test driving it on both highway and local roads to get a full sense of the driving dynamics. The ride quality varies significantly depending on wheel size, with the 19-inch wheels on the S Line being noticeably harsher than the 18-inch option. I prefer the 18-inch wheels for daily driving, though they look less aggressive. The carbon ceramic brakes are an expensive option at over $3,000 and are only worth it if you plan to track the car regularly. The Audi A4 Quattro S Line is a competent luxury sedan that excels at comfortable cruising and confident handling in all weather conditions. It is not the most engaging car in its class, but it is reliable, efficient, and practical for daily use. If you prioritize driving dynamics above all else, you might want to look at the BMW 3 Series or Mercedes C-Class, though those cars come with their own set of tradeoffs regarding reliability and maintenance costs. This car represents a solid middle ground for someone who wants a premium experience without the headaches sometimes associated with German luxury vehicles.
