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 hybrid engine choice they offer. The first one has a Volkswagen-engineered powertrain under the hood, a 8-cylinder, 32-valves 680hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 320hp engine designed by Mercedes Benz.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the same number of safety stars gained in the process. 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? On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, GLE offers a marginal difference of 4% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Mercedes Benz does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Porsche with an average rating of 3.7, and models under the Mercedes Benz badge with 4.4 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 Cayenne rank it on average as 3.0 out of 5, exactly the same as the other one.

Porsche is way more agile, reaching 100km/h in 3 seconds less than its competitor. In addition to that it accelerates all the way to 295 kilometers per hour, 85km/h more than the other car. When it comes to fuel economy an obvious choice would be GLE, averaging around 1.2 liters of fuel per 100 kilometers (235 mpg), in combined cycle. That's 208% difference compared to Cayenne!

Mercedes Benz 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, GLE offers slightly better overall protection and takes the lead. From there things take a different direction, 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... It's not difficult to say then that if I'd need to make a choice, it would definitely be the Mercedes Benz. 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.
