Engines
Petrol
TFSI® direct-injection technology is a unique Audi innovation
that includes supercharging, which 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.
Diesel
We introduced TDI® to the roads in 1989, marking a departure
from the noisy, fuel-thirsty diesel engines of the past. And since
then, we’ve continuously refined it, recently 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.
