As a performance-oriented version of the A4 sedan, the Audi S4 adds more power and agility to the already well-rounded package. While there are quicker and more athletic offerings in the compact sports sedan class, the S4 trades some driving thrills for ride comfort. It can be engaging to drive when called upon and remains serene and relaxed during cruising and on long trips, hitting the sweet spot between luxury and sport. Here in our store, you'll find the right OE & aftermarket parts you need to maintain your car's strong performance, along with 2021 Audi S4 accessories designed to personalize it to your taste.
Every S4 comes equipped with a 3.0-liter 349-hp V6 that pushes it to 60 mph in 4.4 seconds. The engine is linked to a responsive 8-speed automatic transmission and all-wheel drive. The S4 is fitted with a sport suspension that puts it about an inch lower than the A4. To further sharpen handling, the sports sedan can be optioned with an upgraded rear diff, four-wheel steering, and adaptive dampers. With its well-weighted steering, great cornering precision, and high levels of grip, the S4 instills confidence whatever the driving situation, while remaining a calm and comfortable hauler.
Audi's excellence in designing automotive interiors is visible in every inch of the S4's cabin space. The high-quality materials look and feel upscale and costly, and fit and finish are exemplary. Luxurious cues like diamond-stitched leather upholstery and a power sunroof are standard, and accessories & parts like a D-shaped steering wheel and optional sport seats don't let you forget you're inside a performance-biased sedan. Looking to protect and/or customize your cabin? In our online catalog, you'll find a variety of 2021 Audi S4 parts & accessories featuring the style that will match your car's refined interior design and durability to withstand daily wear and tear.
All S4s are equipped with a 10.1-inch center infotainment touchscreen, while Audi's Virtual Cockpit 12.3-inch TFT driver display is an optional extra. The 2021 S4 continues in Premium, Premium Plus, and Prestige trim levels. This year, Audi makes lane-departure warning standard across the board and adds more equipment to the Convenience pack. The mid-level Premium Plus also benefits from the addition of tech features, which include a surround-view camera system, lane-keep assist, and the automaker's intelligent adaptive cruise control, which can slow the car down and speed it up depending on the traffic situation.
