About the 2018 Audi A5
2nd gen (B9/F5), first US year for the redesigned Coupe and Cabriolet, and first US year for the A5 Sportback.
Audi positions the A5 as the style-first choice for buyers who want something more expressive than a typical compact luxury sedan without giving up daily comfort. The core message is sporty design, standard all-wheel-drive confidence, a polished interior, and easy everyday usability. In Sportback form especially, the A5 also adds real cargo flexibility, so the model range blends coupe-like looks with more practicality than many direct rivals.
The Premium trim covers the essentials with leather seats, three-zone climate control, Apple CarPlay, Android Auto, and standard all-wheel drive. Premium Plus adds everyday convenience and safety features such as LED headlights, blind-spot monitoring, parking sensors, and heated front seats. Prestige focuses on cabin technology with a 12.3-inch digital instrument cluster, navigation, a head-up display, a surround-view camera, and Bang & Olufsen audio.
