Engines
Petrol
TFSI® direct-injection technology is a unique Audi
innovation that includes supercharging. It combines
FSI® technology with forced induction – giving cars an
extra injection of power and torque. It also delivers
enhanced fuel efficiency as precisely the right amount of
fuel and air are injected into the combustion chambers,
enabling the engine to ‘breathe’ more easily. It results
in reduced heat loss and increased output, with around
a 15% reduction in fuel consumption and significantly
lower exhaust emissions. The latest addition to the
range is a TFSI full-hybrid which combines the award-
winning 2.0 TFSI engine with a 40 kW electric motor
and lithium-ion battery, allowing all-electric driving over
short distances for the first time in the A6. Please see
pages 16 and 28 for more information on hybrid driving.
Diesel
We introduced TDI® to the roads in 1989, and since
then, we’ve continuously refined it, including developing
common-rail technology. Under this system, a series of
piezo injectors use electrical charge to precisely control
the amount of fuel injected into the engine. As well as
reducing noise, this allows combustion to happen at
a lower temperature, with less oxygen, which lowers
emissions. The recently introduced bi-turbo diesel
engine is our most powerful six-cylinder diesel engine
to date, capable of 313PS and an impressive combined
mpg of 44.8.
