Petrol

FSI® direct-injection technology is a unique Audi innovation

that was originally developed for the Le Mans 24-hour

endurance race to deliver more power and torque, as well as

enhanced fuel efficiency. 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.

TFSI®, which combines supercharging with FSI® technology,

gives cars an extra injection of power. 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 A8. Please see pages

16 and 30 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 cuts down emissions. All A8 diesel

engines are now fitted with AdBlue technology which ensures

compliance with EU6 emission standards.
