The Car Connection's Take

TCC Rating
6.7
6.8
6.7

TCC’s Bottom Line
The 2018 BMW 3-Series makes its strongest case in performance for luxury compact buyers’ attentions. A sports car with a more practical body, the 2018 Cadillac ATS-V represents American engineering at its very best. The Lexus IS needs more powertrain guts, and more styling glory, to tackle the cars it wants to take down.
