/AUDI LIGHTWEIGHT CONSTRUCTION
Lightweight construction, which has been a key technology for
our Company for many years, makes a vital contribution towards
achieving fleet targets for CO2 emissions. More than merely
prioritizing a single material, we follow the principle of com-
bining materials intelligently. The bodies of the new Audi A4
and new Q7 have been designed accordingly. The new Audi A4
Sedan and A4 Avant are up to 120 kilograms lighter than their
predecessor versions, even though their dimensions have in-
creased. For example, the Audi A4 Avant in the basic equip-
ment version with 1.4 TFSI engine weighs 1,370 kilograms
without a driver. Thanks to geometrical lightweight construc-
tion and an intelligent combination of materials, this body has
shed 15 kilograms.
Our new Audi Q7 3.0 TDI quattro redefines the benchmark for
lightweight construction in the premium SUV segment. Thanks
to the new multimaterial body containing high proportions of
ultra-high-strength steels and aluminum, the five-seater with
the 3.0 TDI engine has an unladen weight of 1,995 kilograms
without a driver; depending on engine version, it is up to
325 kilograms lighter than the predecessor model.

/AUDI MODELS WITH AVERAGE CO2 EMISSIONS
OF UP TO 140 G/KM
To coincide with the switch to the Euro 6 emission standard,
we reduced the number of drive versions available in the 2015
fiscal year. By the end of the 2015 reporting year, there were
188 Audi models available with CO2 emissions averaging up to
140 g/km. Of these, 114 drive versions achieved CO2 emissions
averaging 120 g/km or less. 24 Audi models had average CO2
emissions of 100 g/km or less, with 5 drive versions achieving
an outstanding average of 95 g CO2/km or less. In addition to
our alternative drive concepts in the Audi A3 Sportback e-tron
and A3 Sportback g-tron, our particularly efficient ultra models
play a pivotal role in further lowering the CO2 emissions of our
vehicles.
According to official figures released by the European Commis-
sion, the average CO2 emissions figure for new Audi vehicles
sold in the European Union (EU 28) in 2014 was 131 g/km.
Based on provisional calculations, the average CO2 emissions
of newly registered Audi vehicles in the EU 28 is expected to be
around 125 g/km in 2015.
