“Long gone are the days when the A4 was a compact car. Take a seat inside and you might think you're in a midsize sedan, with sufficient legroom for four amply sized adults aboard. And even 6-footers will find enough headroom in back.”—edmunds.com

“Though not especially adventurous, the Audi A4 is thoroughly modern and up-to-date outside and especially inside.”—thecarconnection.com
After inspecting the car closely, we found that there’s nothing in the exterior that has been left unchanged. The sports sedan is longer and wider, with more angular lines across the grille. The detailing is sharp with the character line running through the side profile. Unlike the old model where the tail lamps were weakly approached, the new A4 has got bold cuts to the trunk end.
Design and Styling
2018 A4s design looks evolutionary. The design lining beautifully connects the front spoiler and the rear bumper top, along with the Roofline. This enhances the sporty look and elongated silhouette of the sedan. In order to make the design more unified, the carmaker has made crisp shoulder lines towards the headlights.
