The modular efficiency platform
/ AUDI LIGHTWEIGHT CONSTRUCTION
The principle of lightweight construction and the reversing of
the weight spiral play a significant role in improving vehicle
efficiency. Lightweight automotive construction has already
been a key technology of the Audi brand for many years.
In an effort to further reduce the vehicle weight of new models
across the entire product portfolio, we adhere to the principle
of an intelligent material mix and of integrating functions and
systems into innovative vehicle architectures. The vehicle bod-
ies of the third-generation TT and the new Q7 have also been
designed in keeping with this maxim. Through the intelligent
use of materials in composite construction, we have yet again
reduced the weight of new models.
The new Audi TT 2.0 TFSI with manual transmission and front-
wheel drive weighs just 1,230 kilograms (excluding the driver)
–50 kilograms less than its predecessor. This is another best-
in-segment achievement by Audi.
Audi also redefines the benchmark in the premium SUV seg-
ment with the new Q7. Fitted with a 3.0 TDI engine, it has an
unladen weight of 1,995 kilograms –325 kilograms less than
the predecessor model.
/ AUDI MODELS WITH AVERAGE COĊ EMISSIONS
OF UP TO 140 G/KM
We have achieved further advances in the fuel economy of
our vehicles thanks to the innovative technologies of the
modular efficiency platform. At the end of 2014, there were
already 205 Audi models with CO
2
emissions averaging
140 g/km or less. Of these, 94 drive versions achieved aver-
age CO
2
emissions of 120 g/km or less, and 15 Audi models
even achieved the remarkable figure of 100 g CO
2
/km or less.
Alongside alternative drive concepts – such as the A3
Sportback e-tron and A3 Sportback g-tron – the high-
efficiency ultra models in particular are helping to bring
about a further reduction in our vehicles’ CO
2
emissions.
