2015 Audi S3 Sedan blends Audi’s high-performance and high-tech know-how into a zesty compact sedan. With accurate (albeit lightly weighted) steering, plus all-wheel drive and a sport-tuned suspension, it’s a charming and eager companion. The 2.0-liter turbo four makes 306 hp; a seven-speed automatic is standard. Passengers are treated to comfortable and supportive seats. A 12.3-inch driver-oriented display provides everything from vehicle speed to navigation functions.
