Every movement originates from something. Something that set it off, an idea. The

engines for your new Audi A8 can also be traced back to an initial spark of inspiration:

higher power with lower fuel consumption. These apparently conflicting aims are

reconciled in two revolutionary drive technologies: TDI® and TFSI®. Get acquainted

with both of them. And then opt for the drive system that you feel most moved by.

Maximum power.

Put to maximum use.

The fuel consumption and CO₂ emission figures as well as the efficiency classes can be found from page 94 onwards.

Intelligent performance

Audi TFSI engines attain a particularly high compression rate. The

result: outstanding efficiency combined with optimum performance.

Substituting supercharging for cubic capacity has the effect of

considerably reducing engine size and weight – while performance

remains as impressively dynamic as ever. For power delivery that

will win you over from the word go.

With their combination of direct injection and turbocharging, Audi

TDI engines promise exceptional performance – thanks to their high

torque output over the entire engine speed range with constant

power build-up. They are renowned for being fuel-efficient and for

reducing emissions. But they are incredibly dynamic too – letting

you get the maximum out of any road.

TDI® TFSI®

Even cylinder heads can be intelligent,

as Audi cylinder on demand proves.

Four of the TFSI engine’s eight

cylinders automatically shut down in

the partial-load range. This helps to

lower fuel consumption at the same

time as reducing emissions. And

without the switchover even being

noticed or impairing the driving

dynamics.
