The Car Connection's Take
TCC Rating
6.3
7.0
TCC’s Bottom Line
The 2018 Acura RLX brandishes some exotic hardware, and wraps it in anonymity. The 2018 Audi S6 stands with an impressive hand: quality interior, great performance, functional shape. It's possible to find better examples from other cars, but they all cost significantly more.
