Electrified drive concepts are a further focal area within the technology matrix. Hybrid technology
will play an important role in paving the way for purely electric travel. The Audi Q5 hybrid quattro
has thus been on the market since the end of 2011. The Audi A6 hybrid and A8 hybrid models will
appear on markets in the course of 2012. Under the umbrella brand Audi e-tron, which encom-
passes all-electric drive, plug-in hybrids and vehicles with a range extender, the Audi brand is
stepping up its development activities in the sphere of electric mobility. In the past fiscal year
the technical concept cars that it showcased included the A3 e-tron concept, A2 concept and
Audi urban concept (cf. “Electric mobility” under “Research and Development,” p. 148 ff.).
For electric vehicles to be a genuinely climate-neutral form of mobility, they need to run on
renewable power. AUDI AG has already launched various projects to promote the use of re-
newables such as wind power. In this context, the Company is also investigating the practical
use of alternative fuels such as second-generation biofuels. The Audi brand is also planning to
start production of its first natural-gas vehicle in 2013, the Audi A3 TCNG.

Hybrid models
The Audi brand first demonstrated its expertise in the field of hybrid technology as long ago as
1989, when it unveiled the Audi duo, a technical study based on the Audi 100 Avant. In the past
year, the Audi brand brought the Audi Q5 hybrid quattro onto the market. The portfolio of hybrids
will be extended in 2012 with a full-size sedan, the Audi A6 hybrid and a luxury-class sedan, the
Audi A8 hybrid.
All three models have a 2.0 TFSI engine and an electric motor with a combined system output of
180 kW (245 hp), and can run on the combustion engine alone, the electric motor alone or in the
hybrid mode. They also recover energy during retardation phases, and when accelerating hard
the electric motor supports the gasoline engine.
Assuring a high proportion of electric operation was a key development objective. These vehicles
are capable of traveling at a speed of up to 100 km/h purely electrically – at a constant 60 km/h
they cover around three kilometers with zero local emissions.
Over the standard European driving cycle the Audi Q5 hybrid quattro uses an average of just 6.9
liters of premium-grade fuel per 100 kilometers – equivalent to CO₂ emissions of 159 g/km. The
average fuel consumption of the A6 and A8 hybrid versions is even lower, at 6.2 and 6.3 liters of
premium-grade gasoline per 100 kilometers respectively. The combined-cycle CO₂ emissions of
the Audi A6 hybrid are expected to be 145 g/km, and 147 g/km for the Audi A8 hybrid.
