Comprehensive measures for enhancing the fuel efficiency of Audi models
Audi already has an established reputation among premium manufacturers thanks to its
comprehensive strategy for reducing fuel consumption and emissions across the entire
fleet. These efforts will continue in the future, without altering the decidedly sporty charac-
ter of the brand. Simultaneous action will be taken in four specific areas:
Optimizing
gasoline and diesel engines
Alternative drive systems
and fuels
Improvements to the
total vehicle
Maximizing the
contribution by and for
the driver
Efficiency and sportiness thanks to “Vorsprung durch Technik”
Optimizing gasoline and diesel engines
Gasoline and diesel engines will remain the bedrock of vehicle drive systems in the coming
years. Further optimization of these drive concepts is therefore crucial. Audi has once again
demonstrated its immense expertise in the field of ultra-efficient internal combustion en-
gines through such developments as the progressive TFSI and TDI technologies.
Audi will be putting the ultra low emission system for diesel engines into production ve-
hicles in the U.S. and Europe in the future. The levels of nitrogen oxides in emissions from
modern diesel engines, which are already very low, will then be largely eliminated by con-
trolled injection of an aqueous ammonia solution into the exhaust system. This highly effi-
cient diesel engine will make Audi the first manufacturer ever to comply with the world’s
strictest emission standard (LEV II BIN 5) in California and achieve the EU6 limits that are
currently under discussion for 2014.
