The Car Connection's Take
TCC Rating
8.2
7.0
TCC’s Bottom Line
The 2015 Audi A4 and S4 sedans are tech-laden, trim, handsome alternatives to the other expected German cars, as well as one very good American one. The 2018 Infiniti Q50 is powerful, well-equipped luxury sedan that doesn't quite match up to Germany's finest yet.
