Both TFSI
®
and FSI
®
petrol engines are available on the new Audi Q5. TFSI
®
is a unique Audi
innovation which leads to enhanced fuel efficiency. It combines turbo-charging with the FSI
®
technology that was originally developed for the Le Mans 24-hour race to deliver more power
and torque, while using less fuel. With both engines, precisely the right amount of fuel and air
are injected directly into the combustion chambers, enabling the engine to ‘breathe’ more
easily. At the same time, electronics monitor the engine load and adjust the injection process.
This results in reduced heat-loss and increased output, with around a 15% reduction in fuel
consumption and significantly lower exhaust emissions. Ideal for someone who’s looking for
an uncompromising, exhilarating drive.
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 for even more efficiency and power. 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
and uses less oxygen, which in turn reduces emissions.
