Turbocharged Direct Injection
The Avant was previewed by the Audi Avantissimo concept in 2001 and arrived during the course of 2005. The A6 All-road Quattro made its debut in 2006, and as before, is an off-road-ready version of the Avant, available with either a 2.7-litre V6 or 3.0-litre V6 Turbocharged Direct Injection diesel engines, or a 3.2-litre V6 or 4.2-litre V8 petrol engine.
