http://www.edmunds.com/insideline/do/Drives/Followup/articleId=136386 --- Click here for 2009 Audi Q7 3.0 TDI Track Video Inside Line video Full disclosure: The 2009 Audi Q7 3.0 TDI clean diesel we describe here doesn't yet exist — sort of. Don't get us wrong. Audi is committed to selling an Audi Q7 3.0 TDI with the very same fuel-efficient clean diesel powertrain, and it affirms that the vehicle will appear in showrooms during 2009. But it isn't yet clear whether the first examples of the Audi Q7 TDI will be officially homologated as 2009 or 2010 models. Ah, technicalities.
