Audi S4 Sedan B9

The Audi S4 Sedan B9 is a potent blend of understated German elegance and unapologetic performance. Introduced in 2017, this iteration marked Audi's decisive shift toward turbocharging, swapping out the beloved supercharged V6 for a turbocharged 3.0-liter TFSI engine. With 354 horsepower and a torque curve flatter than the Autobahn itself, the B9 S4 isn't shy about its intentions: it's a refined executive sedan that can embarrass dedicated sports cars at the lights.

Behind the wheel, the B9 S4 reveals Audi's obsessive attention to detail. Its quattro all-wheel-drive system, now smarter and lighter, effortlessly manages grip, making spirited drives feel almost too easy. The eight-speed Tiptronic transmission—controversial among purists who mourn the manual gearbox—nonetheless delivers lightning-quick shifts and seamless power delivery. Inside, the cabin is quintessential Audi: meticulously crafted, technologically sophisticated, and ergonomically impeccable, though perhaps a touch clinical for those craving emotional drama.

Historically, the S4 lineage has always been Audi's quiet rebel, subtly challenging BMW's M and Mercedes-AMG without resorting to overt aggression. The B9 continues this tradition, its design language speaking softly but carrying a big stick. Notably, Audi's Virtual Cockpit debuted prominently here, redefining driver interaction and setting a new benchmark for digital instrumentation. While it might lack the raw, visceral edge of some rivals, the B9 S4's balanced blend of comfort, technology, and blistering real-world pace makes it an enduring favorite among enthusiasts who appreciate subtlety over spectacle.
