The combined effect of these measures is that the front-wheel-drive version of the A7 Sportback
with the new-generation 3.0 TDI engine developing 150 kW (204 hp) achieves average fuel
consumption of only 5.3 liters of diesel per 100 kilometers, which translates into emissions of
139 g CO₂/km. Likewise the new A6 Sedan with front-wheel drive and developing 150 kW (204 hp)
uses just 5.2 liters of diesel over 100 kilometers, representing CO₂ emissions of 137 g/km. The
even more sporty version of the six-cylinder model with an output of 180 kW (245 hp) and quattro
drive manages on a mere 6.0 liters per 100 kilometers in both the A7 Sportback and the new A6,
amounting to emissions of 158 g CO₂/km.
Second generation of 3.0 TDI engine
The second generation of the 3.0 TDI engine brings many new features that optimize its output
and efficiency. The most outstanding features of the six-cylinder engine with a displacement of
3.0 liters are its low weight, low friction and modern cooling concept. These attributes and the
way they combine with other items from the modular efficiency platform produce outstanding
fuel efficiency and CO₂ emissions.
The 3.0 TDI engine is used in a variety of Audi models, its output ranging from 150 kW (204 hp)
to 184 kW (250 hp). Alongside the A7 Sportback and the new Audi A6, it appeared in the Q7
family in fall 2010, for example. The new Audi Q7 3.0 TDI quattro with an output of 150 kW
(204 hp) has average fuel economy of 7.2 liters of diesel per 100 kilometers, corresponding to
189 g CO₂/km. This particularly efficient engine version will also become available in the Audi A8.
With an output of 150 kW (204 hp), the A8 Sedan with front-wheel drive consequently averages
only 6.0 liters of diesel per 100 kilometers and achieves emissions of 158 g CO₂/km.
Models below 140 g CO₂/km
Thanks to the use of efficiency technologies from the modular efficiency platform, numerous
Audi models with powerful TDI and TFSI engines already achieve fuel economy figures that
prove there is no inherent contradiction between sportiness and efficiency.
The Audi brand has thus significantly increased the number of models with CO₂ emissions below
140 g/km in recent years. At the end of 2010 it already had 52 engine versions in this bracket,
one-third of which actually achieved CO₂ emissions of less than 120 g CO₂/km.
As well as economical TDI engines, these efficient models include many TFSI versions. For example
the powerful 1.4 TFSI engine in the Audi A1 with an output of 90 kW (122 hp) and S tronic trans-
mission uses a mere 5.2 liters of premium-grade fuel per 100 kilometers and therefore emits
119 g CO₂/km.
