According to Audi the car is now in final stages of testing before its world unveiling at the Frankfurt Motor Show in September.
Audi says that before the first series production models are delivered later this year, Q7 prototypes and pre-production vehicles will have been put through millions of test kilometres.
"We're putting the Q7 through just about every horror imaginable to a car driver," says Martin Brand, head of durability testing at AUDI AG.
"Never before has an Audi vehicle had to go through such a broad-based spectrum of tasks and operational conditions during testing."
Checks are being carried out on a vast array of test beds, on Volkswagen Group proving grounds, at minus 35 degrees Celsius inside the Polar Circle, in the scorching desert heat of Southern Africa, on the highways of Florida, on dust, grit and gravel in Europe, Asia, Brazil and Central America, through to the gruelling Nordschleife of Germany's Nürburgring.
But this is not all. The Q7 is also being put through its paces on lonely, winding country roads, on autobahns and in the midst of heavy city traffic in congested urban areas.
For over two years now, disguised Q7s have been out and about on public roads, as well as in the most remote corners of the earth, under extreme dynamic, climatic and topographic conditions.
The durability testing chief affords a glimpse into the test catalogue, "The test tracks we use are a collection of the world's worst driving and obstacle routes imaginable in customer operating scenarios - pot holes, rough cobblestones, speed bumps, undulations, grit, non-surfaced roads, gravel, kerbstone mounting, railway crossings, water obstacles.
These are highly dynamic courses, on which driveline, body torsion and bending, as well as running gear durability and functionality are tested." says Brand.
The Audi Q7 will go on sale in South Africa in the second half of 2006
