What Happened to Ford’s Hemp Car?


In the 1940s, Henry Ford, founder of the Ford Motor Company, unveiled a car that was made from hemp and other plant-based materials. The car, known as the “hemp car,” was a groundbreaking innovation in the automotive industry, as it was both lightweight and incredibly strong. However, despite its potential, the hemp car never made it into mass production, leaving many to wonder what exactly happened to this groundbreaking vehicle.

The History of the Hemp Car

Henry Ford’s interest in plant-based materials for cars was sparked by his desire to find a sustainable and renewable alternative to steel and other traditional car materials. In 1941, he unveiled a prototype car made almost entirely from hemp and other plant-based materials. The body of the car was made from a plastic material called “bioplastics,” which was composed of 70% cellulose fibers from hemp, sisal, and wheat straw, and 30% resin binder.

The car was not only lightweight and strong, but it was also ten times more impact-resistant than steel. The hemp car was also designed to run on hemp-based biofuel, making it a truly eco-friendly alternative to traditional vehicles.

Why Didn’t the Hemp Car Succeed?

Despite its promising features, the hemp car never made it to mass production. There were several reasons for this, including the influence of the steel and oil industries, which saw the hemp car as a threat to their dominance in the market. Additionally, the outbreak of World War II led to the diversion of resources and priorities, further delaying the production of the hemp car.

Furthermore, the stigma surrounding hemp and its association with marijuana also played a significant role in the downfall of the hemp car. At the time, hemp was incorrectly categorized as a drug, leading to strict regulations and negative public perception. This made it challenging for Ford to gain widespread acceptance and support for his innovative vehicle.

The Legacy of the Hemp Car

Even though the hemp car never made it into mass production, its legacy continues to inspire innovators and environmentalists today. The concept of using plant-based materials for vehicles has resurfaced in recent years, with many companies exploring sustainable and renewable alternatives to traditional car materials.

Furthermore, the hemp car serves as a reminder of the potential of hemp as a versatile and environmentally-friendly material. As attitudes towards hemp continue to evolve, it is possible that the dream of a hemp car may become a reality in the future.


Henry Ford’s hemp car was a revolutionary vehicle that showcased the potential of using plant-based materials in the automotive industry. Despite its promising features, the hemp car faced numerous obstacles and ultimately never made it into mass production. However, its legacy continues to inspire innovators and environmentalists, serving as a reminder of the potential of hemp as a sustainable and renewable material for vehicles.
