The Car Connection's Take
TCC Rating
7.2
8.2
TCC’s Bottom Line
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. The 2015 Porsche Cayenne is no longer the only blasphemous off-roader in the Porsche family; this year, it gets improved powertrains and massaged looks in a familiar package.
