Audi ultra:
Every gram less extends the lead.
Audi ultra, the pioneering lightweight technology
from Audi, is more than just the sum of its
individual components. It combines innovative
materials, intelligent design principles and
production processes that use resources sparingly
into an overall concept. Many Audi ultra light-
weight measures have already been implemented
in the Audi A8 models.
That starts with the body itself. The Audi Space
Frame (ASF) is made almost entirely of aluminium.
This provides a high level of safety with an agile
driving sensation – and reduced fuel consumption.
New, high-strength aluminium alloys are used for
panels, castings and profiles and further reduce
weight. For the first time, hot-formed steel
panels are also integrated into the body structure
in order to further improve its function. They are
located in the region of the B-pillar.
Audi engines have made drive technologies such
as direct fuel injection and turbocharging more
and more effective. The modern TDI and TFSI
engines in the A8 or S8 models extract more power
from less displacement and thus are significantly
lighter than equivalent engines from earlier
series. This principle culminates in the
combination of a 4-cylinder engine with an
electric motor in the Audi A8 hybrid and
A8 L hybrid.
Each lightweight component has an effect on
other components, allowing their dimensions to
be reduced as well. The result is a continuous
development process towards less and less
weight and more and more efficiency. In figures:
a vehicle that weighs 100 kg less can save up to
0.3 litres of fuel per 100 km.
