TCC’s Bottom Line

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.

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.

TCC Likes

Underrated V-8
Well-appointed interior
Sharp 7-speed dual-clutch automatic

Great exterior curves
Curvy interior
Unspoiled infotainment system

TCC Dislikes

Overshadowed by S7
Steering is too light, too quick?
Exterior is too conservative

Middling powertrains
V-8 is really expensive
Unrefined hybrid
