The Car Connection's Take
TCC Rating
7.0
7.5
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 Cadillac CTS-V scorches the earth, and leaves the E63 and RS7 with some burn marks.
