Audi Supercharger Technology
Alongside Exhaust gas turbochargers, Audi also makes use of Superchargers to Boost its engines. A Supercharger is used in the 3.0 TFSI. The high-efficiency mechanical charger is situated in the 90-degree V formed by the cylinder banks and is driven by the engine via a poly-V belt. The gas pathways downstream of the charger are very short, thus the torque develops quickly and easily. The full Boost is available even at idle. http://www.eurocarnews.com/29/0/1322/0/video-audi-Supercharger-technology.html
