The Car Connection's Take
TCC Rating
7.2

6.8
TCC’s Bottom Line
The 2018 Audi S3 is a blast to drive, but it suffers from a tiny rear seat and the Volkswagen Golf R offers the same performance with more room for less. The 2018 BMW 2-Series is a competent coupe with plenty of power—even in base trim. A sports car with a more practical body, the 2018 Cadillac ATS-V represents American engineering at its very best.
