Once a defining feature of the market, compact luxury sport sedans are much scarcer nowadays. The 2018 Audi S3 is an excellent flag-bearer for the breed, with athletic performance matching Audi’s high-tech expertise. Along with the BMW M2 and the Mercedes-AMG CLA 45, it rounds out the German trio of offerings.
