2021 Audi S4 Premium Plus 3.0 TFSI quattro

Vehicle Description

At Supreme Motors in Auburn, Washington, we specialize in offering the best prices on the cleanest, most dialed-in luxury and performance vehicles in the Pacific Northwest. This 2021 Audi S4 Premium Plus is no exception. Finished in the ultra-rare and incredibly desirable Nardo Gray over Black leather color combo, this example is loaded with all the right packages and shows like-new. This S4 comes with a perfect 1-owner California-owned history and a clean Carfax with zero accidents or blemishes—an absolute must when it comes to long-term value retention and peace of mind. It’s equipped with the Black Optics Package, S Sport Package, Premium Plus Package, Convenience Package, and Navigation Package, making it a top-tier build with every enthusiast and tech-focused upgrade accounted for. The mileage is extremely low, and its West Coast pedigree means it’s never seen salted roads, rust, or harsh weather. This is one of those examples that you hold onto because it checks every box: top-tier spec, perfect history, and rare color combo with all the factory gear that makes the S4 platform stand above any other sport sedan in its class.

Under the hood, the 2021 S4 houses Audi’s tried-and-true turbocharged 3.0L V6 producing 349 horsepower and 369 lb-ft of torque, routed through the ultra-responsive 8-speed Tiptronic automatic and Audi’s legendary Quattro all-wheel-drive system. With the S Sport Package, this S4 gets upgraded to Audi's adaptive damping suspension and a rear sport differential, which completely transforms how this car handles compared to a base model. The sport diff shifts power side-to-side at the rear axle under load, helping carve tight corners and apply power where you need it—huge for anyone who truly drives. The adaptive suspension also dynamically adjusts ride quality and damping based on drive mode, offering the perfect balance between comfort and aggression. This isn’t just a “fast A4,” this is a precision-tuned performance machine that takes on BMW’s M340i and C43 AMG with pure confidence, especially in this package configuration.

The Black Optics Package radically changes the exterior aesthetic and takes this Nardo Gray S4 to a whole new level. Gloss black window surrounds, black mirror housings, and a blacked-out front grille delete the chrome and make the already sinister lines of the S4 even more aggressive. It also includes the 19" Audi Sport 5-V-spoke wheels finished in titanium—lighter and more stylish than the standard wheels, and they pair perfectly with the red S-branded brake calipers from the S Sport Package. The body lines of the B9.5 S4 generation are sharper and more purposeful than ever, and Nardo Gray, a color typically reserved for RS-level cars, takes that design to another level entirely. Subtle fender flares, integrated rear diffuser, quad exhaust tips, and LED lighting all around make this one of the best-looking sport sedans on the market—hands down.

Inside, this S4 Premium Plus doesn’t cut any corners. The virtual cockpit comes standard with a 12.3” high-definition digital gauge cluster that transforms the driving experience, especially with the integrated Navigation Package showing full-screen mapping and route data directly in your line of sight. The MMI Touch Response system and a 10.1” touchscreen interface provide wireless Apple CarPlay, Android Auto, Bluetooth, and full voice command functionality. The upgraded Bang & Olufsen 3D Surround Sound system is crystal clear at any volume, and the Convenience Package adds keyless entry, a power trunk, and auto-dimming mirrors. Premium Plus also brings full LED interior lighting, heated and power front sport seats with driver memory, blind spot monitoring, and Audi Side Assist. The seating surfaces are beautifully stitched leather with diamond-contrast patterning, bolstered for spirited driving yet comfortable for long hauls. Every touch point—from the flat-bottom steering wheel to the aluminum inlays—feels purposeful and precise.

Mechanically, this 2021 S4 is tight, quiet, and dialed. The transmission shifts lightning quick and delivers instant torque without the lag that plagued older turbo engines. Audi has refined this platform significantly, and the B9.5 refresh (2020+) brought meaningful improvements in responsiveness, cabin tech, and exterior design. This car has never been modified, abused, or driven in harsh conditions—another reason the pristine, unblemished history matters. With routine maintenance performed in California and zero deferred service, this S4 needs nothing. Every button, feature, and drive mode operates as it should. The underbody is spotless, the brakes are strong, and the tires still have tons of tread—this is a car you can drive across the country tomorrow or enjoy every day in the city without hesitation.

When you’re comparing this car to others online, make sure you look past just the badge. There are plenty of base models and low-spec examples without the sport diff, without Black Optics, without Bang & Olufsen, or without adaptive suspension. Most of them don’t have a perfect West Coast one-owner history, and most haven’t been owned by someone who took care of it like this. This particular S4, with its full suite of factory options, rare Nardo Gray paint, 19" Audi Sport wheels, and flawless background, isn’t just a better version of an S4—it’s one of the best values in the entire sport sedan segment. At Supreme Motors, we hand-pick every car to meet this exact standard, and we back it with our long-standing reputation for integrity and transparency. This S4 is the real deal—come see why we believe it’s one of the best in the country.
