TCC’s Bottom Line

The 2021 Audi A4 blends a conservative luxury compact car with spicy performance and robust wagon flavors.

The flexible 2021 BMW 3-Series lineup offers something for everyone, so long as they’re not smitten with SUVs.

The 2021 Infiniti Q50 is a sleek, entertaining sedan, but it’s lagging behind newer rivals in comfort and handling.

TCC Likes

Clean interior
Comfortable ride
A4 Allroad is capable off road…

Spectacular engines
Thrill-ride M3
Ride/handling balance

Attractive lines
Twin-turbo acceleration
Decent tech story

TCC Dislikes

Conservative looks
Cramped trunk
Touchscreen looks like an afterthought

No wagon version
No manual, except in M3
M3’s style an acquired taste, at best

Interior’s not so pretty
Gets expensive way too fast
Thirsty, thirsty, thirsty
