40 Audi ultra
Audi ultra:
Every gram less extends the lead.
Audi ultra, the pioneering lightweight technology
from Audi, is more than just the sum of its indi-
vidual components. It combines innovative mate-
rials, intelligent design principles and production
processes that use resources sparingly into an
overall concept. Many Audi ultra lightweight
measures have already been implemented in the
Audi A7 Sportback and S7 Sportback.
That starts with the body itself. The aluminium
hybrid body combines low weight with high
rigidity. And this despite the fact that the body
is made by means of a steel/aluminium-mix
construction method. This results in a high level
of safety and an agile driving experience at the
same time – as well as lower fuel consumption.
Innovative drive technologies such as direct fuel
injection and turbocharging have made Audi
engines more and more powerful. The modern
TDI and TFSI engines in the Audi A7 Sportback
and S7 Sportback produce more power from less
displacement, making them significantly lighter
than the corresponding engines used in earlier
model series.
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 100km.
