This is the new top version in Audi`s V6 engine range. The 3.0 TFSI develops 213 kW (290 hp) and a huge 420 Nm (309.78 lb-ft) of torque. It combines two state-of-the-art technologies in perfect style – gasoline direct injection and compressor supercharging. The hi-tech V6 will go into production later in the year.
The brand with the four rings has a long tradition of supercharged engines. The legendary Grand Prix racing cars built by Auto Union back in the 1930s already featured compressors, which coaxed as much as 440 kW (around 600 hp) out of the mighty 16-cylinder and 12-cylinder engines. From the late 1970s on, Audi focused its attention on the exhaust turbocharger, which helped it to a succession of noteworthy triumphs in the world of motor sport. It was at this time that Audi`s turbo engines began to enjoy resounding market success.
The compressor is now staging a comeback. It is the ideal supercharging technology for the new three-liter V6, the 3.0 TFSI; the T in Audi engine designations consequently no longer exclusively denotes turbo versions.
Extensive comparative tests revealed the mechanical supercharger to be superior to a biturbo concept for this engine. In conjunction with direct injection, its packaging, starting performance and dynamic response were far superior.
The compressor is so compact that it easily fits inside the 90-degree V of the cylinder banks, in place of the intake manifold. Because it is driven by the engine via poly-V belt, its full thrust is available from idle speed upwards, producing huge pulling power when driving off. The 3.0 TFSI delivers its maximum 420 Nm (309.78 lb-ft) at only 2,500 rpm and maintains this constantly until 4,850 rpm.Read All Article
