<strong>Audi</strong> ultra<br />
<strong>Audi</strong> ultra:<br />
Every gram less extends the lead.<br />
<strong>Audi</strong> ultra, the pioneering lightweight technology<br />
from <strong>Audi</strong>, is more than just the sum of its individual<br />
components. It combines innovative materials,<br />
intelligent design principles and production processes<br />
that use resources sparingly into an overall concept.<br />
Many <strong>Audi</strong> ultra lightweight measures have already<br />
been implemented in the <strong>A3</strong> models.<br />
That starts with the body. The steel shell design<br />
of the vehicle combines low weight with high<br />
rigidity. Which type of material is used in which<br />
place on the vehicle is determined by the desired<br />
<strong>Audi</strong> ultra on the podium: the <strong>Audi</strong> R18 ultra<br />
characteristics. The resulting material mix of<br />
hot- and cold-formed metal panels and profiles<br />
in the vehicle body create an ultra-modern<br />
lightweight structure. But not only ultra highstrength<br />
steels are employed, light aluminium<br />
is also used to reduce the weight of attachment<br />
parts such as the bonnet and wings. The<br />
aluminium components on the front axle and<br />
the aluminium alloy wheels not only reduce the<br />
overall weight but also the unsprung masses,<br />
which in turn leads to a further increase in agility<br />
and driving comfort.<br />
The fuel consumption and CO₂ emission figures can be found from page 118 onwards.<br />
Drive technologies such as direct fuel injection<br />
and turbocharging have always made <strong>Audi</strong><br />
engines more powerful. Modern TDI and TFSI<br />
engines produce more power with a smaller engine<br />
size, making them lighter than the corresponding<br />
engines used in earlier model series.<br />
Each lightweight component has an effect on<br />
other components, allowing their dimensions to<br />
be reduced as well. Here, the lightweight body<br />
and lighter engines lead to secondary effects<br />
throughout the vehicle. The weight of many parts<br />
of the exhaust system, suspension and interior<br />
has been able to be reduced. This complete<br />
package of measures for the <strong>A3</strong> models saved up<br />
to 90 kg compared with the predecessor models.<br />
The result of the <strong>Audi</strong> ultra measures is a<br />
continuous development process towards less<br />
and less weight and more and more efficiency.
