5 reasons to buy the 2021 Audi S4

1. Plenty of power 

The 3.0L turbocharged V6 engine of the 2021 Audi S4 has 349 hp, which is plenty of power for a small sports sedan. The 369 lb-ft of torque catapults the 2021 S4 off the line, delivering sports-car-like pace and a claimed zero-to-60 time of only 4.4 seconds. Highly usable performance, whether you’re driving to the creche, meeting friends in town, or taking an interstate road trip, the S4’s power suits every driving occasion. 

2. Sharp style 

The 2021 Audi S4 has sharp lines and a discreet appearance. These low-key looks make the S4 a classy statement and a true sleeper if you want to stay under the radar. Aluminum finishes on the bumpers, mirror caps and side skirts differentiate the exterior from the regular A4, along with 18-inch alloy wheels, quad exhausts, and a trunk lid spoiler. If you want a sleeker presence, choose the Black Optic package on Premium and Premium Plus models for Titanium Black exterior details and a set of 19-inch matte titanium finish wheels. 

3. Interior tech 

The sports-trimmed cabin of the 2021 Audi S4 wows with its mix of finishes and technology. Up front, a 10.1-inch color touchscreen with acoustic feedback controls the infotainment system when on the move. Three-zone automatic climate control will keep all passengers comfortable, and standard wireless Apple CarPlay® and wired Android Auto connectivity will keep everyone entertained. Choose the mid-range Premium Plus trim for a 12.3-inch Audi virtual cockpit digital instrument panel and a wireless smartphone charging pad. Top-spec Prestige trim adds a heads-up display, a navigation system, and a Bang and Olufsen® audio system. 

4. Confident handling 

Audi’s quattro® permanent all-wheel drive is standard on the 2021 Audi S4 for extra traction on slippery surfaces. The AWD set-up means grip is plentiful for added assurance, whether you’re driving to the pool, meeting at the cinema, or tackling mountain road curves. 

5. Available packages 

Attractive available packages for the 2021 Audi S4 boost the specification. If you want an even sportier drive, the S Sport package includes a quattro® sport rear differential for extra performance and grip out of corners, and sport adaptive damping suspension. Red brake calipers add the finishing touch. If you spend time in hotter climates, you’ll appreciate the Warm Weather package featuring ventilated Milano leather front sport seats with four-way power adjustment, and manual rear window sunshades to protect everyone from the sun.
