A4 allroad quattro Audi S4 Saloon

Every movement originates from something. Something that sets it off, an idea.
The engine in your Audi A4 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 110 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.
