Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the suv segment and utilize the same 5-door suv body style and the 4 x 4 wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Porsche-engineered powertrain under the hood, a 8-cylinder, 32-valves 550hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 280hp engine designed by Volkswagen.

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. That aside, let's consider some other aspects which affect safety. 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?

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. These are the official statistics, while our visitors describe reliability of Porsche with an average rating of 3.7, 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. Above it all, drivers of cars with the same engine as Cayenne rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Porsche is way more agile, reaching 100km/h in 3.3 seconds less than its competitor. In addition to that it accelerates all the way to 283 kilometers per hour, 56km/h more than the other car. When it comes to fuel economy the winner has to be Touareg, averaging around 9.9 liters of fuel per 100 kilometers (29 mpg), in combined cycle. We can't ignore that 16% difference compared to Cayenne.

Volkswagen is apparently more reliable, not too much, but just enough. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Porsche outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for 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™, among thousands of similar, yet so different vehicles.
