7/4 2003 scale model - Final MA project.
X-wire technology, as used in the GM Autonomy and Hy-wire, can be used to create a sports vehicle with an entirely modular powertrain at the rear.
Imagine the scenario: the vehicle you use all week on the public highway can be taken to the race track, have its rear unit exchanged for a racing version, and driven to its fullest potential on the track. When its time to go home the units are simply exchanged once more. Track fun....no hassle
