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
lightweight measures have already been
implemented in the Audi A6 and S6 models.
This starts with the body itself. The aluminium
hybrid body combines low weight with high
rigidity. The body is produced in a hybrid steel-
aluminium design. This provides a high level of
safety with an agile driving sensation – and
reduced fuel consumption.
Drive technologies such as direct fuel injection and
turbocharging have always made Audi engines
more powerful. The modern TDI and TFSI engines
in the Audi A6- and S6 models produce more
power with a smaller engine size, making them
significantly lighter than the corresponding
engines used in earlier model series. This principle
culminates in the combination of a 4-cylinder
engine with a hybrid engine.
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.
