This 2012 Audi A4 Avant Premium Plus came from the factory with a turbocharged 2.0 L TFSI inline-four. However that and the factory drivetrain were swapped for a 2012 Audi S4 powertrain. The wagon is now powered by a supercharged 3.0 L TFSI V6 capable of 329 hp (245 kW) and 325 lb-ft (440 Nm) of torque. Behind that is an S Tronic dual-clutch seven-speed automatic transaxle, S4 driveshaft, and sport rear differential. The wagon rides on S4 subframes with KW V2 coilovers, Meyle HD front control arm kit, and Eurocode adjustable front and rear anti-roll bars. Braking is handled by Porsche Macan front calipers with 345×30 mm slotted rotors and Audi S4 rear calipers with 330×22 mm slotted rotors. Those are covered by 19-inch wheels and Michelin Pilot Sport 5 255/35 tires. View more photos and specs on Bring a Trailer.
