Wikispeed is an open source road legal car, for commuting and racing. They take the idea of open source seriously and everyone is invited to collaborate.
Above you can see Car #007, built for testing new part versions. Many parts on this car were waterjet cut by Big Blue Saw: the front pedal plate, the suspension corners, pieces in the engine module and interior, and more.
Being open source, Wikispeed collaborators make use of a variety of CAD software, based on the preference of the individual designer. The most used package is Geomagic, with some members preferring SolidWorks, FreeCAD, or AutoDesk Fusion. The design files are available for free download.
