Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Not only that they both belong to the suv segment and utilize the same 5-door suv body style, they are even powered by the same Audi-developed diesel engine! There is not much there to point us towards one vehicle or the other. Or is it?

The fact that the Volkswagen got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the suv segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, when it comes to weight, a factor that most people underestimate, Cayenne offers a marginal difference of 1% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Volkswagen as a brand displays somewhat better results, when all the models are taken into account. That's the official data, while our visitors describe reliability of Porsche with an average rating of 3.9, and models under the Volkswagen badge with 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as these two vehicles rank it on average as 5.0 out of 5.

Both of the cars accelerate exactly the same, so we couldn't put one above the other. Car No. 1 reaches top speed of 204 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 9.3 liters of fuel per 100 kilometers (30 mpg), in combined cycle.

Volkswagen appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, Touareg beats the other contender by far, making it the best choice without even considering other things. From there things take a different direction, with Porsche being considerably quicker, thus putting more smile on driver's face. Fuel consumption is more or less the same. I believe that, when we take all into account, we have only one winner here - the Volkswagen. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, out of 12.000+ vehicles we currently have in our database.
