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.
TFSI®
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 emission-reducing. But they are
incredibly dynamic too – letting you get the maximum out
of any road.

Audi cylinder
on demand.
Even cylinder heads can be intelligent,
as Audi cylinder on demand proves.
Cylinders two and three of the
4-cylinder TFSI engine automatically
shut down in the partial-load range.
This helps to lower fuel consumption
at the same time as reducing emissions.
Without the switchover even being
noticed or impairing the driving
dynamics.
