Virtual Adviser's™ opinion
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 diesel engine choice they offer. The first one has a BMW-engineered powertrain under the hood, a 6-cylinder, 24-valves 245hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 240hp engine designed by Audi.
SafetyUnfortunatelly, 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, but that fact doesn't break the tie between the two cars. On the other hand, when it comes to weight, a factor that most people underestimate, Cayenne offers a considerable difference of 13% more metal.
ReliabilityI don't like generalizing things when it comes to reliability, although it does seem that BMW does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of BMW with an average rating of 4.1, and models under the Porsche badge with 3.9 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 BMW X6 rank it on average as 4.3, while the one under the competitor's bonnet gets 5.0 out of 5.
Performance & Fuel economyBMW is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 210 kilometers per hour, 4km/h less than the other car. When it comes to fuel economy the winner has to be BMW X6, averaging around 7.4 liters of fuel per 100 kilometers (38 mpg), in combined cycle. We can't ignore that 26% difference compared to Cayenne.
Verdict
Porsche 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, Cayenne offers significantly better overall protection, taking the lead here. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. BMW X6 , on the other hand, consumps significantly less fuel, and that's a big plus. No mistake, whatever you decide here, but I'd still go for the BMW. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
