Audi calls it the Sportback body style but you likely know it as a hatchback or liftback. It’s a design Audi first brought to market with the A7 model line and now makes it available as an A5/S5 variant. While the Coupe and Cabriolet feature 2 doors and a traditional trunk, this high-performance S5 Sportback is a 5-door design with considerably more passenger and luggage volume, moving it from the subcompact to midsize realm. With seating for up to 5, the S5 Sportback offers 35 cubic feet of cargo capacity with the rear seats folded down, nearly tripling the trunk volume of the standard Coupe.
