During the fuel shortages of World War II, Alfa Romeo explored alternatives such as electric transport and made a new model trolleybus, the 800AF, to replace the 140AF. The electric generators were produced with more efficiency. It used a body from Garavini.
The length is around 9 m and had 2 wheelbases. The height is 2005 mm and the width is 2210 mm.
It was constructed for the trolleybus network in Turin.
