2021 Audi A6 vs. Its Competition

2021 Audi A6
Aaron Cole Aaron Cole Managing Editor

The Audi A6 is most often compared to the Mercedes E-Class and BMW 5-Series.

The E-Class is also available as an off-roady wagon for interested buyers, but the sedan is more popular and comfortable.

The 5-Series is relatively old, compared to the bunch, but offers high-performance variants and a plug-in hybrid.

The Cadillac CT5 is a step smaller, but more affordable.

We expect more performance variants to come.

The Jaguar XF is handsome and available as a wagon but compromised in its interior.

The Tesla Model S is the all-electric option and it looks good, but won’t appeal to all buyers.

Quick Specs
The 2021 Audi A6 mid-size luxury sedan or wagon is reserved but flexible in its powertrain offerings and body styles.
The 2021 Mercedes-Benz E-Class promises better tech inside and more capability outside with the arrival of a lifted wagon.
The 2020 BMW 5-Series is the goldilocks mid-sizer with a roundel on the hood: comfortable, powerful, and luxurious.
The 2020 Cadillac CT5 mid-size luxury sedan offers a new look—but not a new idea—for the automaker in a competitive class.
Especially in wagon form, the 2020 Jaguar XF is an appealing luxury car for those of us not totally sold on SUVs.
Growing old though it is, the Tesla Model S still looks and feels as fresh as when it first debuted eight years ago.
