The 2015 Audi S3 is a compact luxury sports sedan from the German carmaker's performance-oriented 'S' lineup. It is based on the A3 platform with notable enhancements reflecting its performance bias. The S3 is powered by a 2.0-liter TFSI, four-cylinder engine, producing 292-horsepower and 280 lb-ft of torque. Paired with a six-speed dual-clutch automatic transmission, it sends power to all four wheels via Audi's Quattro all-wheel drive. Available in two trims, Premium Plus and Prestige, it comes standard with Automatic climate control, leather upholstery, and Audi’s MMI infotainment system with a 7-inch retractable display. CarPlay or Android Auto was not available for the 2015 model. Notable safety features include a pre-collision safety system and stability control. The 2015 year model introduced a more aggressive exterior design, while retaining Audi's signature luxury and refinement.
