Summary

The 3.0l TFSI represents the new top-of-the-range V6 engine from Audi. In its basic form this engine design delivers 213 kW (290 bhp) and 420 Nm.


The fundamental design of the engine has been adopted from the naturally aspirated V6 engines as revised in 2006, including the measures to reduce frictional losses. An entirely new development is the supercharger module, with integrated Roots blower, bypass regulation and charge air intercooling.


All the components are accommodated inside the V. As a result of the extremely compact dimensions it has also been possible to adopt the arrangement of the inlet and exhaust systems directly from the naturally aspirated engines without any changes. In conjunction with direct injection, this sets new standards in terms of responsiveness, efficiency and noise levels.


The new Audi V6 3.0l TFSI combines excellent torque and power output with outstanding responsiveness, along with the package and exhaust-related benefits of a naturally aspirated engine. That makes it ideally suitable for a wide range of applications within the Audi model portfolio. The initial launch of the engine will be in the new A6 for the autumn of 2008.
