The Car Connection's Take
TCC Rating
7.2
7.8
TCC’s Bottom Line
The 2021 Audi A6 mid-size luxury sedan or wagon is reserved but flexible in its powertrain offerings and body styles. The 2021 BMW 5-Series pushes all the right buttons for mid-size luxury shoppers. And there are a lot of them. Made as a sedan, wagon, coupe, and convertible with four different powertrains, the 2021 Mercedes E-Class has wide appeal.
