Parking assistance
Who hasn't found themselves trying to park in a parking slot and not being able to do so, while other drivers behind get impatient? To avoid this, Franco Sbarro has come up with solutions to make maneuvering easier.
Robur small wheels
Two small wheels have been fitted to the rear
of the Robur. These descend like landing gear. So, to park in
a jiffy, all you have to do is move the nose of the car into
the parking space, and the transverse wheels will take care of
stowing the rear of the car. You don't have to be an expert to
park in town. This ingenious system had been around for a long
time (an inventor in the 1920s had proposed an equivalent
system, but nobody wanted it), but Sbarro was the only one to
offer it in 1988.
Swivel wheels
The Assystem
City Car is a car apart from all the prototypes built by
Franco Sbarro. It's a kind of synthesis of everything Sbarro
invented in the course of his career. Dual-frame chassis,
autonomous drive wheel and rhomboid wheel arrangement. Thanks
to this wheel arrangement, the car is surprisingly
maneuverable. The front and rear wheels swivel on themselves,
offering an unrivalled turning radius. The car can turn on
itself.
This swivel-wheel principle was reused by Sbarro in 2017 for
the Tracto-sphere
and in 2019 on the El
Richo prototype.
