TCC’s Bottom Line

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

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…

Attractive lines
Twin-turbo acceleration
Decent tech story

TCC Dislikes

Conservative looks
Cramped trunk
Touchscreen looks like an afterthought

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