Petrol Diesel

There are two kinds of engine available on this model – the W12 petrol engine

and the FSI

direct-injection engine. FSI

is a unique Audi technology,

originally developed for the Le Mans 24-hour endurance race to deliver

increased power and torque as well as enhanced fuel efficiency. The way it

does this is, in theory, very simple. Fuel is injected directly into the

combustion chambers, ‘unthrottling’ the engine, reducing heat-loss and

increasing output – all whilst reducing fuel consumption and exhaust

emissions. Ideal for the buyer who wants a sporty, exhilarating drive without

the drawbacks of excessive fuel costs or high emissions-based taxation.

All diesel engines from Audi are known as TDI

. This impressive technology was originally

pioneered by Audi in 1989, marking a departure from the noisy, fuel-thirsty diesel engines

of the past. Like its FSI

petrol counterpart, the TDI

diesel engine is designed for power and

performance, with low fuel consumption and CO

2 emissions. The working principle of the

TDI

engine is based upon precision and compression. A turbocharger supplies fresh air to

the engine, ensuring optimum filling of the cylinder. Immediately after compression, an

injector then delivers fuel into the combustion chambers at a very high pressure. The

result – you get the most in terms of performance and economy from every drop of fuel

that enters the tank.
