TCC’s Bottom Line

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

The 2020 BMW 5-Series is the goldilocks mid-sizer with a roundel on the hood: comfortable, powerful, and luxurious.

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

Handsome interior
Great powertrains
Excellent safety scorecard

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?

Gets expensive quickly
Conservative exterior
Small electric range (530e)

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