The Audi A7 Sportback is making its debut at the North American International Auto Show next week in Detroit. It's the first time the car will be seen at an auto show, following the reveal in Ingolstadt last October.

It's the second-generation of Audi's big four-door hatchback coupe. It has more space, more power, new tech, and an updated interior.

The new design takes inspiration from the Audi Prologue concept from 2014. It's the same design that appeared on the new A8.

The new A7 is bigger. Just over half an inch in total length, and nearly a full inch in the interior. That means more comfortable seating for rear passengers. They get both more leg room and more headroom despite the stylish sloping roofline.

All A7 models will use Audi's new 48-volt electrical system that uses a belt-driven starter/alternator to help power a lithium-ion battery. It has a 3.0L turbo V6 that makes 340 hp and 369 lb-ft of torque, up 7 hp and 44 lb-ft from the outgoing model. It also has a new 10.1-inch MMI infotainment system and Audi's 12.3-inch virtual cockpit visual display.

After the Detroit show unveiling, sales are expected to start in February.
