Chassis

The Wikispeed car(s) is always evolving, so it's best to start with a piece that hasn't significantly changed in a while. The basic chassis is nothing more than 4" square aluminum extrusion welded into a series of boxes. However, it has a 5-star crash equivalency rating, verified by independent testing at the Progressive Automotive X-prize. It is only around $550 in parts and those parts are commodities, so they can be overnighted pretty much anywhere in the world. All you need to build the chassis is an average sized garage, a saw to cut the aluminum, and a welder to fasten it together.

Illustrations are on the way.

BOM

• 4" x 1/8" thick square tube
  • 120" long (x4)
  • 40" long (x4)
  • 12" long (x6)
• Yeah, that's it. That's all the frame is made out of :-)

Project Steps

• Cut aluminum tube to specified lengths
• The only location that needs to be measured
  • The center vertical tube is 36" from the inside of the vertical tubes on the open end of the chassis and 72" from the inside of the vertical tubes on the closed end
  • Other than that, everything lines up on obvious edges
