Chassis Module – The structural heart of your modular creation.

Crash tested, fuel economy tested, and able to sit 4 adults, each 270lb and 6’2″, with a mid mounted engine behind them. This extruded aluminum chassis is intentionally sized to fit inside a standard pickup truck bed with the tail-gate down, built by volunteers in WikiSpeed shops all over the world, then inspected and non-destructively tested for flexural strength.

We’ve used it for ultra-efficient commuter car prototypes and race cars. The chairman of Boeing’s Future of Flight Museum remarked “If you bolt wings on it, that would make a competitive small aircraft!” What will you build with it?

Details: Extruded Aluminum 6061-T6. 124 lbs (weight varies with aluminum stock and who is doing the welding). Overall dimensions 48″ wide, 120″ long, 20″ high. Composed of 4 pieces, each 120″ long, extruded aluminum square tubes, 4″x4″x.125″ thick wall, joined by 8 shorter lengths of the same tube. Total contains 40′ of extruded aluminum tubing, TIG welded together and inspected. Cosmetics vary widely. Please assume you’ll want to file the edges and wipe-down your chassis when it arrives.


4″x4″x.125″ extruded square tube 6061-T6 makes you the lightest chassis in the world to achieve a 5 star crash rating equivalency. We say “Equivalency” because the NHTSA and IIHS have not yet published a rating of our chassis. We have performed crash testing in a certified facility (CAPE in Indiana) and the chassis survived the offset frontal impact test and side impact test without intruding into the driver.

Chassis arrives TIG welded or packed with CNC plates to precision bolt your chassis together, please specify which you prefer or we’ll ship whichever we have on hand first. There are pros and cons to each. The TIG welded chassis is lighter and has more flat surface for bolting additional modules, the bolted chassis has no heat effected area for maximum strength and is re-boltable for future configurability of even the chassis itself.

All prices plus actual shipping (typically FedEx freight, 125lbs per chassis module, bolt together chassis weighs more). Actual shipping will be billed separately.
