The Car Connection's Take

TCC Rating

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.

The 2021 Mercedes-Benz E-Class promises better tech inside and more capability outside with the arrival of a lifted wagon.

TCC Likes

Wide span of performance
Available wagons
Great interior tech

Varied powertains
Spacious interior
Performance and efficiency options

Great tech
Updated looks
Off-road wagon, finally

TCC Dislikes

Conservative looks for some
Pricey premium engines
Stylish A7 is right next door

Body hasn’t changed much
Real hides cost extra
Active lane control isn’t standard

...and none of them are cheap
How long will the plug-in hybrid go?
Synthetic leather in a $60,000 car?
