Inspiration series 4: VW Beetle

The biggest example of a nationwide effort for affordable mobility is the VW Beetle, the so-called “peoples car”. Personally I think the car was far too technical for its time, If not for the enormous amounts of free labor invested in the development, the Beetle would have been more expensive that it was.

Compared to the 2CV, the VW beetle is a Lexus. It was design for the German autobahn, while the 2CV was designed for unpaved country roads. Its solid build is light years ahead of the rickety 2CV and its price despite being very cheap, was still double that of the 2CV. Regardless the car had as much technical innovation as the 2CV, because it was spearheaded by the Best Engineer in his era Ferdinand Porsche. Porsche used rear mounted air cooled engine constructed out of lightweight magnesium, specially treated anticorrosion steel chassis, the first use of a torsion bar suspension, acrylic paint and a very aerodynamic shape for its day.

The car was thoroughly tested and engineered to standards that rival today’s cars. For a Nigerian car, going in the direction of the beetle would lead to bankruptcy and total failure, because the government is not ready to pour in such an investment. But key concepts from its design can be taken into consideration, like the rear mounted air-cooled engine, and aerodynamic shape. The beetle shows what can be done when a whole nation puts its back behind a technical endeavor. The end result was a car that was more advanced than anything in production at the time and yet affordable by the masses

Inspiration series 3: Citroen 2CV

When Citroen launched the 2CV (known as Citroën "Baby-brousse" in most of West Africa) at the Paris auto show in 1948, it was laughed at by journalists for being too Spartan. Nevertheless the rest of the French population fell in love with the styling, affordability, and ruggedness. It was the car that put France on wheels. It would go on to become one of the greatest small cars ever built with passionate fans all over the world. The car used innovative features like an H-frame chassis similar to airplanes of the time, front wheel drive, fully independent suspension, lightweight air-cooled flat twin engine.

The car used a simplistic approach, adopting many mechanical and few electrical parts. Even the side windows would flip-up rather than wind down; a very cheap, yet effective feature. The roll-up fabric roof allowed for quicker roof assembly and provided open air motoring. The air-cooled engine had no distributor and required no radiator and the accompanied complex piping. This made for a very reliable engine not even the VW beetle could match.

Today this car gets praise, but it is good to know that it met some hurdles during its development most notably world war 2. Prototypes were ordered to be destroyed for fear of German acquisition of the technology, but some well deserving engineers, buried some of the prototypes, preserving what would become the iconic 2CV. Development started in the mid 1930’s, but it was not until after the war in 1948 that the world first gazed eyes upon the car.

Of all the cars in my inspiration series, the 2cv is the one I admire the most; mainly because it was not just cheap, but technically innovative. No other car in history has inspired countless engineers working on affordable mobility more than the 2CV. Its final success as well as the struggles in early development harbors some vital lessons for any car envisioned for a developing country.

Nexo Urban: An example for naijacar

The nexo urban car project is a concept that follows closely to what naijacar is trying to achieve. It was the second price winner of the 2006 Innovar Inventions contest in argentina ( a contest that nigeria should emulate) It was design by Indutrial designers Ernesto Frias and Nicolás Alem. The car uses simple forms for easy production, a bunch of similar parts, and symmetrical door assemblies to increase economies of scale. it can be adapted to suit any market application. There are many ideas in the project that are similar to the naijacar project. Its great to see people in other developing countries are exploring such a concept.
