These vehicles were designed and built in the early 1920's in France by a gent named Marcel Leyat.
The name "Helica" is derived from the French word for "Propeller" and these propeller-driven automobiles were an extension of his earlier experiments, building a propeller-driven tricycle.
In the long term, these machines were not a success and the concept has disappeared from our streets and highways. However, at the time the Helica was being promoted, one of these machines was actually driven down the streets of Paris.
In the picture below, a Helica is being test driven at on "le mans" racetrack.
