A coupe. A wagon. And now an offroader. The Audi Prologue Allroad Concept is the third in a series of show cars pointing to the company's future. This rugged five-door is powered by a hybrid system that pairs a twin-turbo V8 with an electric motor for 734 hp and a 0-62 time of just 3.5 seconds, yet offers 98 mpg fuel economy. Other forward-looking features include a touch-screen instrument panel, an OLED center console display, LED rear lights, Matrix laser headlights, and a rear sound spoiler for improved audio, all wrapped in a sleek-yet-stout body that's raised to help it tackle any terrain.
