TCC’s Bottom Line

The 2021 Audi A6 mid-size luxury sedan or wagon is reserved but flexible in its powertrain offerings and body styles.

The 2020 Cadillac CT5 improves upon the agile CTS and at a substantially lower price.

TCC Likes

Wide span of performance
Available wagons
Great interior tech

New look for Cadillac
Strong turbocharged powertrains
Quick-shifting 10-speed automatic

TCC Dislikes

Conservative looks for some
Pricey premium engines
Stylish A7 is right next door

Divisive exterior style
Does it have enough to sway luxury buyers?
Will it be a good size for U.S. shoppers?
