Voison Laboratoire Racing Car Paper Model of a 1923 Voison Laboratoire Racing Car

An Unusual Car

The Voison Laboratoire was an experimental French racing car from 1923, made by the Voison aircraft company.

Among its unusual features were:-

• streamlining, though the slab-sided design probably had a fair bit of vortex generation drag as the air flowed from the curved top sideways down to the flat sides
• no differential gear to reduce weight - the rear wheel track is very narrow to reduce the wheel-slip that results from having both wheels turning at the same speed
• a quiet sleeve-valve engine (popular for aircraft even up to the 1940s)
• aluminium body panels
• rectangular steering wheel

However, it did not have enough power, and was unsuccessful.

Here are some more pictures of the model.

It was not as easy to build as I thought, but on the second attempt I got it right. Problems were keeping the body alignment correct, and making the wheels (latter is a common problem for any paper car).
