Motorsport In motor racing, APR Motorsport has currently entered a B8 S4 in the Grand-Am Continental Tire Sports Car Challenge Grand Sport (GS) class. B9 (Typ 8W, 2017–present) Audi announced the B9 S4 in 2015, with the official unveiling of the European-spec model at the 2015 Frankfurt Motor Show. Noticeable changes to the B9 included a modern, more angular exterior, newly designed wheels, and a new turbocharged V6 engine. Unlike the pre-facelift B8 S4, the announced European-spec model is only available with an eight-speed torque converter automatic (ZF 8HP55a). The new model uses LED main-beam and LED daytime running lights as standard, alongside dynamic turn signals and LED tail-lights. Like other Audi models, the notable feature in the new S4 is Virtual Cockpit which has Classic Layout and Sports Layout in displaying speedometer and tachometer. The B9 S4 features standard 18-inch 5 double-spoke wheels with summer tires, or optional 19-inch 5 V-spoke wheels. The B9's brakes use multi-piston calipers, replacing the single-piston sliding calipers of earlier models. LED headlights are standard while a flat-bottomed steering wheel, "S" embossed seats, and quad tailpipes differentiate the S4 from the B9 A4.

As a result of the powertrain upgrades in the new S4, it now can accelerate from 0 to in 4.2 seconds. It is electronically limited to a top speed of . In European markets, the facelifted B9 S4 - launched in 2019 - is now powered by a 3.0-litre turbocharged diesel V6 with and , mated to a ZF 8-speed torque converter automatic gearbox and all-wheel-drive.
