Summary

In 1989, Audi introduced its 2.5 TDI, the first direct-injection diesel engine for passenger cars. This engine soon became the trendsetter in DI- diesel technology. The new 3.0-litre V6 TDI is the first volume-produced diesel in the new Audi-V-engine family with 90 mm cylinder centres distance. It complies with the extremely stringent EU IV exhaust emission limits by means of internal measures alone, even in the luxury car class and with automatic transmission and the quattro drivetrain. The new 3.0-l V6 TDI engine has a maximum power output of 171 kW (233 hp) and a torque of 450 Nm. Its features include four valves per cylinder and a turbocharger with variable turbine -geometry, and it is the first engine on the world market to use the Bosch third-generation piezo common rail system with a maximum injection pressure of 1600 bar. The new V6 TDI is notable for its very high performance and impressive refinement. With its compact dimensions and numerous new technical solutions, Audi has once again established a milestone in TDI technology.
