How big is it? Imagine a really sexy A8, minus two doors—the Prologue is essentially as wide and long as the sedan, but the roofline is much lower than the A8's formal limousine profile. If you're rooting for this to get greelit for production, join the club. The concept car's power comes from a monster version of Audi's 4.0-liter twin-turbo V8, whose wick is dialed up to 605 hp and 516 lb-ft of torque (553 lb-ft with overboost), channeled through an 8-speed auto to all four wheels via quattro. Audi saus 0–60 takes just 3.7 ticks.

The areas on either side of the wheel let the driver control the essentials like lighting and media. The area in front of the passenger seat also lets that person control entertainment features and perform tasks like entering navigation info, which can then be swiped, tablet style, to the driver.
