Aerodynamic tests in the Pininfarina wind tunnel at
Grugliasco have been conducted on the urban car project
that has been developed by the students of the H2politO
Team of Turin Politecnico. The vehicle, XAM (eXtreme
Automotive Mobility), is a low consumption city vehicle
prototype wholly designed, engineered and developed by
the students.
Fitted with an innovative hybrid powertrain consisting
of a small bioethanol-driven engine and an electric
motor, the vehicle has been designed to comply fully
with the severe regulations imposed by Shell on those
taking part in its competitions. XAM, however, also
allows for the needs of a car market that is in the
throes of profound, constant change. Apart from its
participation in the Shell Eco-marathon, XAM represents
a vehicle-workshop in which it has been and will be
possible to develop in-depth studies on materials and
technologies in the search for efficient, innovative
responses to the sustainable mobility needs of today and
above all of tomorrow.
In its ongoing effort
to improve results and develop vehicles in view of the
prestigious competitions in which it plans to take part
in the immediate future, the Team took advantage of the
support offered by the Pininfarina Wind Tunnel, where it
was possible to test XAM experimentally in various
aerodynamic configurations and establish the most
appropriate modifications to apply to the next vehicle.
Since 1972, the
Pininfarina Wind Tunnel has been a centre of excellence
for aerodynamics and aeroacoustics research and
development. Modern systems and advanced measuring
technologies are available to support research work. The
Tunnel mainly operates on 1:1 scale vehicles in the
aerodynamic and aeroacoustic sectors but an equally
important field of activity is Wind Engineering
(aerodynamic studies on buildings, industrial plants,
bridges, sun shades…) and aerodynamic research for
sport.
In the two years it
has taken part in the European edition of the Shell
eco-marathon with XAM, the H2politO Team has won
prestigious prizes like the “SKF Design Award” in 2011
and the “Communication Award” in 2012. XAM has also
managed to cover 107 km with the energy equivalent of
one litre of petrol.
