Audi Q7 TDI Review

The Audi Q7, first introduced as a 2007 model, shares a platform with the Volkswagen Touareg and the Porsche Cayenne and is definitely the best looking of the three.  Resembling more of a tall station wagon than anything else, it appears smaller than it really is.  Its mammoth proportions (it …

Many people don’t realize that diesel-powered passenger cars date back to the mid-1930s.

König Diesel: Driving the New BMW 7er Series

The 7er Series, as BMW’s flagship, may cocoon its driver and passengers in Teutonic luxury and is clearly automotive royalty.  While I was somewhat ambivalent about the exterior of its predecessor, the new 7er is a true blue blood, and not just because of its Bavarian heritage.
To me, it looks …
