Finding a parking spot is hard enough but
finding one large enough for your car is another thing! Now there
may be a solution in the future with the Presto concept car.
The Rinspeed Presto transforms itself in a
few seconds from an under-3-meter long two-seater roadster -
presto! - into a 3.7-meter long four-seater with plenty of room
for the rear-seat passengers. The additional space can also be
used as a pick-up bed for cargo when the rear-seat backrests are
This almost magical transformation is made possible by a centrally
located electric motor, which stretches the vehicle with the help
of two mechanical screw-and-nut gears by exactly 746 millimeters
to its full extended length of 3.74 meters. The longitudinal
members run on low-friction precision rollers and disappear like a
drawer in the rear of the floor pan. Despite its variable length
the engineers succeeded in designing the adjustable Presto floor
pan with the torsional rigidity necessary for a roadster. To
ensure absolute operational safety the extension mechanism also
features self-locking safety latches.
A four-cylinder, 1.7-litre common-rail turbo diesel engine in
dual-fuel configuration, based on a Mercedes-Benz engine, provides
future-oriented and highly environmentally friendly propulsion.
The engine runs on a mixture of natural gas and Diesel fuel at a
40 to 60 ratio. Natural gas is a very clean-burning fuel, which
consists almost entirely of methane with sulfur content near zero.
However, since a Diesel engine has no spark plug to act as an
ignition source, operation on natural gas alone is technically
In its role as a quick, highly maneuverable
city speedster the Presto appears stocky yet sporty, thanks to
extremely short front and rear overhangs. With a wheelbase of
1’750 millimeters and an overall length of 2.99 meters it can fit
even in the smallest parking spaces.
As a four-seater with a wheelbase of 2’496 millimeters the
roadster appears much sleeker, poised to strike. The Remus side
pipes are more than just a sporty styling element. They also
allowed the engineers to avoid a variable and complicated exhaust
routing. During the transformation process the body glides past
the side pipes without interference. Since the Presto does not have
any doors, the upper side pipes are designed to swing out and make
entering and exiting the vehicle easier for the little ones.
The entire body of the Presto consists of Pre-Preg-Composite, a
modern plastic material rarely used in vehicle design for cost
reasons. It offers extraordinary stability at comparatively low
Galvin Manufacturing Corporation introduced the
first car radio in 1930. It was named "Motorola" linking the ideas
of "motion" and "sound." Motorola later becomes the brand name for
all Galvin Manufacturing Corporation's products.
