Self Study Program 925803 – Audi 3.0 V6 TFSI engine with Roots blower

AUDI SSP

VAG SSP 925803. For the first time, Audi has brought to market a mechanically supercharged powerplant: the 3.0l V6 TFSI. This Roots blower supercharged engine is based on the 3.2l V6 naturally aspirated engine from the current Audi V-engine family. By embracing new technology, in combination with the FSI combustion process, Audi has developed an engine concept that has impressive compact design, acoustics, responsiveness and fuel efficiency.

The engine has a broad range of characteristics from comfort-oriented to ultra-sporty. The sporty version of the engine specifically targets US clientele. The car’s so-called take-off behavior plays a key role to achieve the greatest possible acceleration between traffic lights in urban traffic.

With its enormous power the 3.0l V6 TFSI engine is also well suited to comfort-oriented driving. A wide range of uses have been envisioned for it within the Audi product portfolio. In Europe, China and the USA, it will be available beginning in the Fall of 2008 in the Audi A6.

Historically, mechanical supercharging using Roots blowers is nothing new to cars bearing the four-ring badge. In fact, Roots blowers were once used on the engines of the legendary AUTO UNION racing cars (“Silver Arrows”), which were powered by huge V engines with up to 16 cylinders supercharged by up to two Roots blowers. Between 1934 and 1939, the legendary AUTO UNION drivers spearheaded by Hans Stuck and Bernd Rosemeyer racked up numerous Grand Prix wins, not to mention setting a string of world speed records.
