TCC’s Bottom Line

The 2020 Audi A6 is as good as mid-size luxury sedans get—for those still shopping sedans.

In its final year, the 2020 Cadillac CT6 is a tempting look at what could have been from the luxury brand.

TCC Likes

Smooth, supple ride
Plenty of power with V-6
Refined interior

Spacious rear seat
Big V-8 for its final year
Smooth ride

TCC Dislikes

Small trunk
Looks like every other Audi
Can you have too many touchscreens?

It’s gone soon
The V-8 is hilariously expensive
Never caught on
