Audi Prologue Concept - LA Auto Show - Referred to internally as the A9, the  Prologue, is the first Audi penned by new design chief Marc Lichte. Easily recognized as an Audi, only   with a wider and lower front grill and a sharper point to the already sexy Audi headlights. Under the hood is a 4.0-liter twin-turbo V8 producing 605 horsepower and 516 pour-feet of torque linked to an eight-speed automatic transmission and Quattro all-wheel-drive. Audi claims the Prologue will propel its 4,365-pounds from 0-60 in just about 3.5 seconds. Look for rear doors in the production model, and these styling cues on all Audi's in the years to come.
