TCC’s Bottom Line

The 2020 BMW 3-Series is back on top among compact sport sedans, even as the competition closes in.

The entry-level 2020 Cadillac CT4 sedan presents a value that is quickly eroded by a lack of features standard on other luxury makes.

The 2020 Mercedes-Benz C-Class is as gorgeous inside as it is outside, and it has moves to match.

TCC Likes

Dual personality
Longer, wider, stronger
Impressive technology

Good infotainment
Smooth 10-speed automatic
Powerful 2.7-liter turbo-4

Have it your way body styles
All of which are gorgeous
Strong powertrain lineup

TCC Dislikes

8-speed automatic only
Added dimensions don’t add much inside
No electrified powertrains to start

No standard AEB
Monochrome interior
Cramped rear seats

Manual would be nice
Hefty pricetag
Rear-seat and cargo space just so-so
