The Car Connection's Take
TCC Rating
6.7
7.0
6.7
TCC’s Bottom Line
The 2018 BMW 3-Series makes its strongest case in performance for luxury compact buyers’ attentions. The 2018 Infiniti Q50 is powerful, well-equipped luxury sedan that doesn't quite match up to Germany's finest yet. The Lexus IS needs more powertrain guts, and more styling glory, to tackle the cars it wants to take down.
