The passengers sat behind each other as in an aircraft. The vehicle was steered using the rear wheels and the car was not powered by an engine turning the wheels, but by a giant propeller powered by an 8 bhp Scorpion engine. The entire body of the vehicle was made of plywood, and weighed just 250 kg , which made it dangerously fast.
In 1927, A Hélica reached the speed of 171 km/h at the Montlhéry circuit.
