Concept level cars fall into two categories in general, and the first one is the flight of fantasy   with vehicles having odd number of wheels, a fish tank-like steering wheel or nuclear powered. These automobiles companies offering these oddballs are sometimes challenged by journalists to build them.

Secondly we have concepts cars which are actually slightly disguised production level vehicles with a year or two remaining before they debut at the showrooms. In this category falls the Audi Prologue, which made its debut at the Los Angeles show. This concept does not fly in the air, or goes invisible and it just appears like the big coupe with passenger and cargo space, the type that the Audi might produce, and people think that they should. The Prologue is a fully-fledged driving automobile which we would certify as we have driven it around the Los Angeles.  

This is something which is never going to happen. A concept car might come very close to reality, but it will still be a one model machine spending millions of dollars to make. In a convention center, the concept is considered a stout machine if it does not dissolve under lights. I have just  driven the Chevy Camaro concept, the only one of my life, and it fell apart and burned to the ground within three minutes after I have left the scene.  I was quiet stimulated by the thought of the Prologue  stationed at the SLS Hotel, the concept which was a paper sketch four months ago, and wanted to explore it. 

When asked the Audi executives if I could pull back the wraps on the car and snoop a little   such as opening the hood to see what is nestling there. The leader of the Audi team said that the hood does not open.
