TCC’s Bottom Line

The 2015 Audi A6 may look a little sedate, but it's a brilliant performer–thanks to its diesel-driven TDI, the supercharged A6, or turbocharged S6 versions.

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

The "wow!" moment of Google Earth maps
Interior's strikingly finished
Great fuel economy (2.0T, TDI)

Great exterior curves
Curvy interior
Unspoiled infotainment system

TCC Dislikes

A five-seater for four people
The CVT's a skipper, we think
Audi's own A7 is better looking

Middling powertrains
V-8 is really expensive
Unrefined hybrid
