2003 So-Cal speed shop - Chrysler Land speed racing proposal
These renditions were made for a presentation to Chrysler to build a Chrysler 300 to go over 300 miles / hour to celebrate the revival of this particular model.
Although the idea was well received, in order to reach the desired speed a Hemmi engine was required and Chrysler had no intentions to offer the car with such engine, therefore that was the end of that project.
