Sometimes concepts are far-fetched dreams. Other times, they offer a glimpse at the future of the company. The Audi Prologue Concept is the latter. This sporty coupe features a striking, masculine design dominated at the front by an oversized grille and wide, flat lasser projection headlights, features likely to be adopted by future production models. It's powered by a 4.0 TFSI V8 engine producing 605hp, good for a 0-62 time of 3.7 seconds. Other features include a touch-screen instrument panel with an OLED display, a luxurious interior, and, of course, quattro all-wheel drive .
