The condensed history:

    The February 1982 Mechanix Illustrated debuts the Urba Centurion. Back then, for a mere $17.95, you could buy information that outlined how to build the car. It was not a kit. The buyer of the plans would source the parts needed (new or used) and then build the body from scratch using fiberglass over a foam core.
    Following the blueprints to include using a small Kubota diesel engine into the aerodynamic body, the finished project was advertised to deliver as much as 128-mpg! The plans by the original designer are still available today at: http://www.rqriley.com/cent.html

A little more info:

    The Urba Centurion was not a completely anonymous car. If you have an eye for detail, you could catch a glimpse of it in the futuristic Arnold Schwarznegger movie "Total Recall" from 1990.

Are there any other Centurions? Yes!:

    A fairly extensive search using the internet will show 2 such examples.

    One variation exists in the Lane Motor Museum in Nashville Tenessee.

    The other is seen here at CrazyJerry's diesel-bike.com website.
Below are the only Urba Centurions known to exist:

There is still more to do:

    Gear changes to optimize mpg and speed.
    Final cooling system tweaks and upgrades (Heater installed 2013. Radiator upgrade pending.)
    Final engine alignment and driveline balance (completed - 10/2012)
    Body work such as pinch flanges, fitment, and blocking for straightness.(ongoing)
    Paint on hold. Kinda liking the primer rat-rod look!
    Current mpg: 127!! (mixed town and rural driving). Exceeded Target of 115 mpg or more...To be continued....
