Francisco Gaitan Sanchez, with the help of his son Francisco Gartan Quintero, built a few three wheeled prototypes called Auto-Tri. There are few versions: Turismo, Comerciale and even an ambulance.
Another model with egg-like aluminium body has two front and a single rear wheel.
The Auto-Tri are powered by 125 cc engines. Traction is front or rear depending on the model, since it is always exerted on the axle with one wheel.
The "AUTO-TRI Gaitan" was presented to the public for the first time in November in Seville.
