E-V Concept  Designs - Prototypes

Concept Designs and prototypes commissioned by Clients

What was once our personal vision for our own electric transportation became the vision of Electric Vehicle Concepts. In the 1970's there were little to no full sized freeway capable electric vehicles offered in the world. Today in 2020 we are still designing and building electric vehicle concepts and electric kit cars for private individuals and other companies from around the world.

In 1973 our first fiberglass body design was commission by the king of Thailand (minister of finance) for the country. Some of his staff saw some of our electric conversions while in the United States. He wanted to produce some EVs in his country. Very progressive for 1972.

I had the freedom to create my own design.

This was not a copy of the real Ferrari BB512 (Boxter Berlinetta). This was our own creation using the features I loved about the BB512 Ferrari. We have used the molds for numerous other builds.


The Rixter roadster. This concept retro roadster was named after the client Rick R--- that commissioned the build in 1988. The concept was to blend the old vintage 32 low boy with modern aerodynamic lines.

Very few people would have seen a sixty year old 32 Ford. So this made it a new concept to most people. Being electric powered was a thing of the future. We might call it a retro mod now days. We have used the molds for a number of builds. With a change of fenders, tops and noses it was unique for each client.



The Sigma GTE and E-Varri motorcycle electric concept designs were commissioned by a Brazilian biodiesel manufacture. Their vision was to bring an exotic electric car to the world market.

This was ten years before any other companies like the Tesla Roadster was introduced. The U.S. company AC Propulsion in the early 2000s was the designer of the Tesla Roadster (Lotus Elise).

The Sigma was designed for international sales and the high speed autobahn of Europe. This was the start of the lithium battery age. The electric car could now be lighter and still have good range in colder weather.

The Sigma GTE was designed as all wheel drive. One drive motor on the front axle and one motor on the rear axle. This gave the car good traction on ice covered roads and twice the power of any electric cars seen at that time. Twenty years later we see two motor AWD as rather common on expensive EV's.

We had been racing our electric conversions against gas cars in the 1970's. This Sigma GTE was the most powerful road course racer we had ever designed and more torque than any gas production car.


The company continuing to want to play and decided to build an electric motorcycle. The concept digital designed drawings came from an Israeli design engineer. They had no affiliation with Ferrari.

The Lightning electric motorcycle is what they called it. A electric start up company from Florida. They brought me a custom pro street Harley rolling chassis and some conceptual drawings. I build the plug for the molds on the chassis. Made body parts from the molds. Created the 120 volt electric drive systems using the A123 spiral Lithium ion cells.


The Facade was our only four door concept. The design was put together by a European import export company. The original design build was done using the Dodge Intrepid with it's cab forward design created by the association of Lamborghini designers when Lamborghini was owned by the Chrysler corporation. This was now the hybrid array. The next donor vehicle was the Honda Civic four door hybrid.


A company from Atlanta Georgia asked for a electric vehicle concept. They called it the Black Mamba after the deadly snake. Some design changes were made from the original drawing.

The project was not 100 percent complete as the company members fell out of funding.

The car ran but the doors were not finished as intended in the drawing.

Seemed common as everyone is excited in the beginning.




This was a redesign of a 38 Ford delivery van we did more than ten years earlier. The intent here was to use a mass produced front wheel drive vehicle so once the gas tank was removed we could lower the floor and add a wheel chair ramp up the back. This was done with a PT Cruiser. All done in steel but the fiberglass fenders that were modified from other parts we had. Molds were made from there. We had done a PT cruiser electric conversion earlier in our history. Commissioned by an elderly friend for his wife.

Since 2015 we have seen some very good mass produced cells that now cost less than our lead battery technology. This has really opened up a new world for electric propulsion of all kinds of vehicles.
