About This Vehicle

Highlights 6 items

THIS... is a 2021 Audi S4 Premium Plus, finished in Audi Exclusive blue with a black interior.

✓

The attached `Carfax` history report indicates no mileage discrepancies in this Audi’s past. It also shows registrations in California and North Carolina since new.

✓

According to the window sticker provided in the gallery, this S4 cost $66,370 new. A partial list of notable factory equipment includes the Premium Plus, S Sport, and Black Optic packages, dynamic steering, and heated front seats.

✓

Notable modifications reported by the seller include 19-inch OZ Racing wheels, an 034Motorsport transmission mount, and Signal Blue Alcantara door panel inserts.

✓

The B9 generation saw the S4 return to its roots, ditching the supercharger for a single twin-scroll turbo. Like the larger V8s in the RS6 and RS7, the V6 uses a "hot inside V" configuration with the turbocharger, exhaust manifolds, and exhaust ports all nestled inside the V of the engine. A ZF 8-speed automatic replaces the prior 7-speed dual-clutch transmission, and this upgraded powertrain can take the S4 from 0-60 in just 4.2 seconds, according to Audi.

✓

Power comes from a turbocharged 3.0-liter V6, rated at 349 horsepower and 369 lb-ft of torque. Output is sent to all four wheels via an 8-speed automatic transmission and Audi’s Quattro all-wheel drive system.
