The New Audi A6 | Part Four

Petrol engines

The powerful 4.2 V8 with chain drive made an outstanding debut in the Audi S4 towards the end of 2002. Now this supreme power unit has been re-tuned and updated for the new Audi A6, offering powerful torque up to maximum engine speed plus an agile response and superior fuel economy all in one.

The new 3.2 FSI six-cylinder has all the features of a cutting-edge petrol engine. Direct fuel injection with on-demand fuel supply, four-valve technology, a variable intake manifold and infinitely variable camshaft adjustment gives the driver dynamic and powerful reaction to every movement of the accelerator plus a broad useful speed range of up to 7200 rpm, muscular torque and an equally high standard of fuel efficiency.

The new 2.4 V6 is the entry-level power unit leading into the versatile range of petrol engines available for the Audi A6. Based on the new engine block of the 3.2-litre power unit and featuring intake manifold fuel injection, this smaller engine provides an exemplary synthesis of superior performance, refinement and exemplary fuel economy.

TDI engines

The new 3.0 TDI six-cylinder engine introduces outstanding power and muscle in the sporty business class, offering output and torque highly impressive in every respect: 225 bhp and 450 Newton-metres. Maximum torque is available just above idle speed, starting at a mere 1400 rpm and giving the driver forceful acceleration at all speeds. Further fortes are the engine's highly efficient noise management and fulfilment of the strict EU 4 emission standards.

This versatility of the highest calibre is based on the latest generation of common rail fuel injection with piezo injectors conveying fuel into the combustion chambers at a pressure of up to 1600 bar and in five carefully graded stages.

The 2.0 TDI four-cylinder version with unit injector is one of the most modern engines in the market today. Again, the particular strength of this engine is its outstanding output and torque combined with equally impressive all-round economy. The new Audi A6 2.0 TDI is able to easily cover a range of more than 1,100 kilometres or 680 miles on one single tank (market launch: the second half of 2004).
