The Car Connection's Take
TCC Rating
8.0
7.0
TCC’s Bottom Line
The 2018 Audi S4 balances perfectly performance with luxury in a package that's both practical and sharp. Hardly a recipe for excitement, but one that touches all the bases. The 2018 Infiniti Q50 is powerful, well-equipped luxury sedan that doesn't quite match up to Germany's finest yet.
