Audi is set on making a difference in green vehicles with their new technologies, which covers alternate fuels, the latest clean diesel and a hybrid version of the Q7, as reported by The Gazette.

These were discussed in Audi’s TechDay forum in Ingolstadt, Germany, including the great developments the German carmaker has done in recent years.

One of these is impressively shown in Audi’s engine. The 2.8-litre and 3.2-litre FSI engines feature a variable valve-lift system which is more efficient, since it can operate on a low-lift cam lobe below 4,000 rpm. If more power is needed, the engine can easily deliver it by switching to a high-lift lobe.  This engine generates more power and can reduce fuel consumption by more than five percent.

Aside from all the benefits in terms of power the new Audi engines, the exhaust also come into play.  In fact, the latest 3.0-litre V6 TDI that will debut in mid-2008 in the Q7 has an ultra-low emissions system.
