Reviewed a 2019 Audi A6 on Jul 22, 2025
This car came loaded with every feature I was looking for. Blind spot monitoring, adaptive cruise control, vented seat, ect. I definitely got what I paid for in a good way. I wish the outside of the car had a sleeker design.

The A6 Avant from 2010-2011 can do it all. Its a rare car that is a family hauler, mountain climber, and it puts a smile on your face every time you drive it.

Why it stands out
The 2019 Audi A6 stands out as a redesigned midsize luxury sedan that was described as a new standard-bearer in Audi’s lineup. It is also presented as both instantly familiar and radically different from its predecessor, which captures the car’s appeal: it keeps the familiar Audi sedan formula while introducing a more modern character.
What makes the 2019 A6 distinctive is the combination of a completely new approach to Audi’s Multi-Media Interface, a light-electrified hybrid powertrain, and more sophisticated driver-assistance technologies. It was initially available with a single drivetrain choice and in Premium, Premium Plus, and Prestige trim, so the lineup was straightforward even as the car itself moved the brand forward. Owners also praised its blend of luxury, performance, and advanced technology, along with the interior design, virtual cockpit, and touch screen controls.
