Exploring the Audi A4 B9 Sedan (2019–2023): The Subtle Art of Getting It Right
I’ve spent enough time in the Audi A4 B9 (the 2019–2023 facelift cars) to know its rhythm. Early mornings on choppy city streets, late-night highway stints, and the occasional sneaky backroad detour when the sat-nav “accidentally” rerouted me. The takeaway? The Audi A4 B9 is one of those premium sedans that doesn’t need to shout to be heard. It’s confident, clever, and just calm. And that’s sometimes exactly what you want.
What the Audi A4 B9 Got Right (2019–2023)
Think of the Audi A4 B9 as the “don’t overcomplicate it” school of engineering. The facelift brought sharper styling, smarter tech, and a mild-hybrid touch on the 45 TFSI. I noticed right away how it tiptoes over rough city seams—firm, but not brittle—and how the cabin stays hushed enough to hear your kids negotiating back-seat armrest rights. On a rainy commute, quattro just quietly gets on with it. No drama, no flashing lights. Grip, go, done.
Engines, Performance, and Efficiency: Audi A4 B9 in the Real World
The 2.0-liter turbo four (45 TFSI) is the sweet spot here. Earlier cars pack around 248 hp; later 2021+ models bump to 261 hp with a 12V mild-hybrid setup. Torque sits at a healthy 273 lb-ft, and 0–60 mph lands in the mid-5s depending on spec. In daily life, it feels brisk rather than breathless—swift overtakes, quiet at cruise, and an easy 27–30 mpg combined if you’re not constantly “testing” the throttle. Honest moment: the dual-clutch’s low-speed response can occasionally feel a hair too cautious in stop-and-go, but the payoff is quick, smooth shifts once rolling.
- Power: 248–261 hp (model-year dependent)
- Torque: 273 lb-ft
- 0–60 mph: approx. 5.2–5.6 seconds
- Combined MPG: roughly 27–30 mpg (driving style matters—always)
- Drivetrain: FWD on some trims; quattro AWD widely available/standard in many markets
Inside the Audi A4 B9: Tech, Comfort, and the Little Things
Slip into the A4 and it’s like putting on those perfect slippers you pretend are “house shoes” when company visits. Seating position is spot-on—low enough to feel engaged, high enough to ease a long commute. Materials? Typically Audi: soft, solid, and mercifully understated. The 10.1-inch touchscreen replaces the old rotary controller. It’s quick and intuitive most of the time, and the Virtual Cockpit remains a highlight if you love a crisp map right in the cluster. I did miss the old dial for eyes-off-the-road inputs—touchscreens demand attention—but at least climate controls stay gloriously physical.
Feature highlights on the Audi A4 B9

- Virtual Cockpit digital gauge cluster

Audi A4 B9 vs. The Class: How It Stacks Up
Spec sheets don’t tell the whole story, but they do frame the conversation. Here’s a quick look at how the A4 compares with its usual rivals.
| Model | Engine/Power | Torque | 0–60 mph (approx.) | Combined MPG (approx.) | Drivetrain |
|---|---|---|---|---|---|
| Audi A4 B9 45 TFSI (2019–2023) | 2.0T I4, 248–261 hp | 273 lb-ft | 5.2–5.6 s | 27–30 | FWD or quattro AWD |
| BMW 330i (G20) | 2.0T I4, 255 hp | 295 lb-ft | 5.3–5.6 s | 28–30 | RWD or xDrive AWD |
| Mercedes-Benz C300 (W206) | 2.0T I4 + mild-hybrid, 255 hp | 295 lb-ft | 5.9–6.2 s | 27–29 | RWD or 4Matic AWD |
| Acura TLX (2.0T) | 2.0T I4, 272 hp | 280 lb-ft | 5.9–6.1 s | 24–27 | FWD or SH-AWD |
My two cents: the BMW is the keener handler, the Mercedes leans luxury, and the A4 strikes the most natural balance between the two with a class-leading cabin and that quietly competent AWD security. If you ski, live in rainy climates, or just prefer a car that’s easy to trust on bad days, the Audi’s composure wins hearts.
Ownership Notes: The Bits You Learn After a Few Thousand Miles
- Ride/Noise: Calm at highway speeds, with just a hint of road texture on 19s. On 18s, it’s plush enough for long family trips.
- Tech Quirk: Touchscreen is quick, but smudges; voice commands help. I occasionally missed the old MMI rotary dial.
- Space: Rear legroom is solid for two adults; three across is a squeeze on long hauls—normal for the class.
- Maintenance: Regular oil changes keep the 2.0T happy. A few owners mentioned minor water pump seepage over time—worth watching during service visits.
Where the Audi A4 B9 Fits in Your Life
Weekend in the mountains? Quattro will get you up the access road without a sermon about snow chains. Downtown date night? The interior feels expensive without shouting about it. School run? Quiet enough to hear sibling politics from the back seat, which, depending on your mood, is either priceless or… perhaps too quiet. It’s an all-rounder that never feels like a compromise.
Conclusion: Why the Audi A4 B9 Still Makes Sense
The Audi A4 B9 (2019–2023) doesn’t chase trends—it perfects the fundamentals. Smart power, quiet confidence, top-tier cabin execution, and tech that mostly gets out of your way. If you want a premium sedan that makes every day better without demanding attention, this is it. And if you’re the type who keeps things immaculate, those tailored A4 B9 floor mats will keep it looking fresh for years.
