A
The Audi brand’s modular efficiency platform brings together
all technologies that help to realize further reductions in fuel
consumption and CO2 emissions. It draws on wide-ranging
components from many different technology areas. The modules
in the efficiency platform are continually being supplemented
and expanded. The new technologies are gradually rolled out
in the Audi brand’s car lines in connection with model change-
overs and product improvements. For example, the cylinder on
demand technology that can improve fuel efficiency by up to
20 percent by deactivating cylinders is already available on three
different engines.

“New engines – driving fun and efficiency”

/ AUDI LIGHTWEIGHT CONSTRUCTION
Audi reached a milestone back in 1994 with the use of alumi-
num in lightweight automotive construction. In that year, the
Audi A8 became the first production sedan to feature Audi
Space Frame (ASF) technology. We have set ourselves the goal
of further reducing vehicle weights across the entire product
range by using an intelligent mix of materials and by integrating
functions and systems into trendsetting vehicle architectures.
We will position appropriate flagship lightweight models in
every vehicle segment in the future.
/ AUDI ULTRA
The term Audi ultra extends beyond the actual product and is
considered synonymous with all-encompassing, sustainable
efficiency. Audi is developing increasingly economical engines
and using ever-lighter materials. We aim to further reduce CO2
emissions in our products’ phase of use, and employ natural
resources sparingly during our production processes. In the
future, the most economical model in each car line, whether
diesel or gasoline, will bear the “ultra” name. By way of an
example, the new Audi A3 1.6 TDI ultra with an output of 81 kW
(110 hp) achieves average consumption of 3.2 liters of diesel
fuel, with CO2 emissions of 85 g/km. It is available in both
three-door and five-door versions and is the most economical
vehicle in the A3 family. Audi will build on the ultra strategy in
2014 with the gradual roll-out of 11 new, exceptionally efficient
models in the A4, A5 and A6 car lines. With the extensively
reengineered 2.0 TDI power unit, the combined-cycle fuel con-
sumption ranges between just 3.9 and 4.6 liters of diesel per
100 kilometers. CO2 emissions of 104 to 119 g/km mean the
new Audi models are among the most efficient in their segment.
