Our previous SGT01 and Roadster are available as open-source CAD hosted by Open Source Ecology. You can read more about them in the Archive, below.

Now we are supporting Tesla automobiles. We enjoy these ultra-efficient, ultra-safe, ultra-fast vehicles for race track use, off-grid camping, and office space. We may in future develop modification packages for Tesla vehicles, for example full racing conversions, Tiny House Tesla RV’s, and customized Tesla office interior enhancements, by request. You are invited to share your stories to popularize the use of these environmentally friendly vehicles and send inquiries to us at

ARCHIVE: SGT01 and Roadster

In 2010 we tied for 10th place in the Mainstream Class of the Progessive Insurance Automotive X Prize, achieving 109 mpg combined EPA city/highway in simulation of that test. We received $10,000 in road legalization testing and consulting as our consolation prize. With that money, we developed the Roadster, which we sold in our online store as 8 separate modules.

We also worked on:

A next generation mail delivery vehicle for postal services globally. We did not win the bid, but if we had we intended to update this design for use as a compact, ultra-efficient RV camping vehicle and a light commercial delivery vehicle.

A next generation taxi cab vehicle for global use.

An ultra-light racing vehicle to campaign at the world’s most famous race track, the Nuremburgring. We have a prototype there currently under development by LG WikiSpeed.De.

An ultra-lite 5 seat sedan as part of ARPA-E’s LiteCar Challenge.

Our open source roadster is shown below:




You may prototype your own WIKISPEED car with us from our Open Source plans for free.

Developed as a Minimum Viable Product and descended from our eco-challenge race car, the modules previously available for sale skip every amenity except a smartphone dock in the dash panel.  They do not have a lockable trunk, roof, or cup holders.  Step over the side crush structures and fixed door panels then sit down inside like a pure race car for the ultimate in light-weight and simplicity.

  • We have tested the car internally, while campaigning in the Progressive Insurance Automotive X Prize, and with Roush Industries where it scored 69.01 highway on it’s best run before we found the wheels were dragging on the dynamometer and the testing facility fan was not blowing on our cooling system, meaning we are confident we can score much higher. We subsequently switched to electric drive only.

WikispeedThree2106eWe have built to NHTSA and IIHS specifications.  The car has been impact tested at CAPE in Indiana, where the driver’s seat broke loose, allowing us to discover faulty MIG weld seams.  The seat mounts were then replaced by bolt-in plates, and we are iterated to replace all welded joins with bolt-in gusset plates.  The car has a driver’s air bag but we did not develop an airbag sensor strategy and airbag computer We did prototype our own Open Source airbag computer and firing system but did not verify the reliability and timing of the device to our satisfaction.

  • 0 to 60 MPH came in 5 seconds with a Honda R18 engine from a 2006-2011 Honda Civic 1.8l., the electric version was subsequently even faster.
  • Top speed of 149 MPH with a Honda R18 engine from a 2006-2011 Honda Civic 1.8l.
  • The ultra-efficient gasoline engine was mid-mounted for optimum efficiency of power delivery and minimal energy loss when turning. There is room for 4 adults, just barely, or 2 adults with childseats or parcels in the back. And it’s super fun.
  • Mechanicals serviceable by any shop equipped to service current generation Honda engines. Modules slide out, providing access to all sides of most components, for ease of self service if desired.


  • Snow and foul weather stable handling with the engine directly over the driven wheels. It’s similar in foul weather to a Honda Accord.

Last EPA test 69 mpg hwy, need to run new test.
WHAT IF WE ALL SPENT TWO HOURS A WEEK DESIGNING THE VEHICLES OF THE FUTURE? At WIKISPEED we are driven to do awesome things to change the world for the better.
