The Car Connection's Take
TCC Rating
6.3
7.2
TCC’s Bottom Line
The 2018 Acura RLX brandishes some exotic hardware, and wraps it in anonymity. The 2018 Infiniti Q70 stands alone as a warm take on luxury that others have left behind. It’s not as luxurious as the others—but it’s not as expensive as those, either.
