2021 Mercedes-Benz C Class vs. Its Competition

2021 Mercedes-Benz C-Class (AMG C63 S)
Andrew Ganz Andrew Ganz Senior Editor

For generations—both of car designs and in terms of humans—we’ve been pairing the Mercedes C-Class against the BMW 3-Series and the Audi A4.

They’re still a valid trio to cross-shop today.

Look to the BMW for its spectacular powertrains, or the A4 for its approachable technology.

Don’t forget about the sublime Volvo S60, which is a screaming deal compared to its German rivals even if it doesn’t offer the hefty punch you’ll find in an AMG C63.

The Alfa Romeo Giulia is loaded with character, which is a nice way of saying that it’s definitely not for everyone.

But we like it, so consider it.

Don’t nix the Cadillac CT5.

Its pretty profile gives way to impressive dynamics and a price tag lower than you might expect.

Cadillac may have finally figured out small sedans.
