Audi presented the latest generation of its 3.0 TDI engine at the 35th International Vienna Motor Symposium. The new V6 diesel is more powerful, more efficient and cleaner than ever.
Audi offers the exhaust turbocharged V6 in two versions producing 160 kW (218 hp) and 200 kW (272 hp). It features a 90‑degree cylinder bank angle and a displacement of 2,967 cc. Peak torque is as much as 600 Nm (442.5 lb-ft) depending on the model. Although the new 3.0 TDI is significantly more powerful than its predecessor, it is – again depending on the model – as much as 13 percent more fuel efficient.
The new V6 diesel is packed with numerous high‑end features. The piston rings and pins have been optimized for minimal friction. The crankcase and the newly designed cylinder heads have separate coolant loops. The updated, innovative thermal management system improves efficiency even further. The turbocharger and the fully variable‑load oil pump have also been updated. For the first time in automotive history, a NOx storage catalytic converter has been combined with a diesel particulate filter and SCR injection in a single assembly.
The exhaust gas after‑treatment integrated into the engine package satisfies the most stringent of emissions legislation, including the Euro 6 standard. It also reduces CO2 emissions by an average of 15 grams (24.1 g/mi). This improvement earns the 3.0 TDI the “clean diesel” suffix.
