TCC’s Bottom Line

The 2021 Mazda 6 drives the point home: not every family needs a crossover SUV.

The 2021 Nissan Altima has a plain-spoken appeal, not to mention high safety scores and a great low price.

TCC Likes

Head-turning style
Impressive optional turbo powe
Sharp handling

Good value in base versions
Sharp exterior
Standard safety features

TCC Dislikes

Some unexpected cabin noise
Pricey Signature edition
Base engine’s moderate power

Interior is a little dull
Turbo-4 isn’t worth the cost
Just adequate power with base engine
