We're accustomed to automobiles that function like living rooms -- temperature controlled with entertainment at the ready, isolated from the hazards of the road. But prop-driven cars offered a much different sensory experience. Why was the cockpit open, despite the obvious dangers?

  • Open cockpits were typical of automobiles and aircraft of the era.
  • It was the best way to enjoy the aromas of the French countryside.
  • Engineers were experimenting with ejection seats, and didn't want a roof to get in the way of a bailout.

How did a prop-driven car run in reverse?

  • The driver switched the propeller to the "reverse" setting, and the change in airflow pushed the car backward.
  • The driver shifted the transmission to reverse.

  • It was pretty.

How many propeller-driven cars did Marcel Leyat build?

  • He built 25 to 30 cars.
  • He built only the six documented Helicas.
  • No one really knows, because his records were destroyed in a fire.

So, how did a prop-driven car work, anyway?

  • Like a wind turbine: the propeller powered the motor that turned the car's wheels.
