New Audi A8 3.0 TDI Quattro

Press Release

Seven-hole injector nozzles are used. The blind-hole injectors produce a good spray pattern; they have micro-blind holes, which have the advantage of low dead volume and a high injection pressure. As a result, mixture preparation is more effective and combustion is highly efficient and creates very few emissions. For a luxury class car, it is obvious that an acceptable noise pattern is needed. Thanks to the piezo injectors and the single or double pilot injection volumes which they permit, combustion can be extremely smooth. Combustion noise is distinctly lower than from any known diesel engines. This is an impressive step forward in diesel-engine development that our customers will appreciate every time they drive the car. Good mixture formation and acoustics have enabled the compression ratio to be lowered to 17 : 1, which benefits both power output and emissions. The maximum absolute boost pressure is 2.3 bar.

A few words now about the performance of the engine and the car:

The 3.0-litre V6 TDI engine??????????????????????????????????????s thermodynamic potential is evident in its power output, torque and emissions. At 233 bhp, the V6 TDI sets a new standard among all current six-cylinder passenger-car diesels in this The maximum torque of 450 Nm is reached at an engine speed of only 1400 rpm and remains constant at this high level all the way up to 3250 rpm. In addition, the new V6 can claim that the low exhaust emission values it achieves in the EU4 test are achieved solely by internal engine design measures. The particulate emissions are at an especially low level. Both fuel consumption and performance values are excellent. The overall average fuel consumption is 8.4 litres per 100 kilometres. The A8 3.0 TDI quattro accelerates from 0 to 100 km/h in 7.8 seconds and has a top speed of 243 km/h. With its new 3.0 V6 TDI engine, Audi once again demonstrates its TDI competence in a most impressive way. The three-litre engine, in addition to its qualities as a sprinter, has admirable acoustic properties and refinement, and will set a standard in its class that drivers will be able to sample and appreciate day after day.
