Mobility based on alternative drive technologies and the increased use of renewables will be essen-
tial if CO2 emissions are to be permanently lowered. At Audi, we do more than simply consider
the CO2 emissions produced when a vehicle is driven; we also look at the wider environmental
footprint of products over their entire life cycle. In this context, the Audi Group is also involved
in various research projects such as the Audi e-gas project, where gas generated from renewables
for use as vehicle fuel is its end product, and a highly promising concept to manufacture new
biofuels (Audi e-ethanol and e-diesel) that can be used instead of conventional gasoline and
diesel (cf. “CO2-neutral mobility” under “Research and development,” p. 154).
MILESTONES IN EFFICIENCY TECHNOLOGY FROM THE AUDI BRAND
Hybrid models
The Audi brand enjoys a long-standing reputation as an expertise carrier in hybrid technology.
The Company’s first venture into this area was in 1989 with the Audi duo, a technology study
based on the Audi 100 Avant. In the past fiscal year, we expanded our portfolio of hybrid models
with the Audi A6 hybrid full-size sedan and the Audi A8 hybrid luxury sedan.
These two models’ drivetrains share many common features and combine the best of both power
sources. The combined system output of the 2.0 TFSI engine and electric motor is 180 kW
(245 hp), with a torque of 480 Nm. The lithium-ion battery located at the rear acts as the energy
store. It is cooled with air in two different ways, depending on requirements – by a blower from
the interior, and by a separate refrigerant circuit that is linked to the deluxe automatic air condi-
tioning. This technology keeps the battery at an appropriate temperature level across a wide
range of situations, assuring a comparatively high proportion of electric operation. The Audi A6
hybrid full-size sedan and the Audi A8 hybrid luxury sedan can travel at up to 100 km/h purely
electrically. Both hybrid models can cover around three kilometers at a constant 60 km/h with zero
emissions. The hybridization process is to be rolled out gradually across other car lines as well.
