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 petrol engine choice they offer. The first one has a Porsche-engineered powertrain under the hood, a 8-cylinder, 32-valves 400hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 350hp engine designed by Volkswagen.
SafetyThe fact that the Audi got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, offers a slight advantage, as the 4-star rating is better than none. 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, 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, Audi Q7 offers a marginal difference of 8% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Audi does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of Porsche with an average rating of 3.7, and models under the Audi badge with 4.2 out of 5. The same official information place Cayenne as average reliability-wise, and Q7 is more or less at the same 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 4.9 out of 5.
Performance & Fuel economyPorsche is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. In addition to that it accelerates all the way to 258 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy an obvious choice would be Cayenne, averaging around 10.5 liters of fuel per 100 kilometers (27 mpg), in combined cycle. That's 21% difference compared to Audi Q7!
Verdict
Audi 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 my opinion, everything taken into account, Audi Q7 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. To make things even better, it consumps less fuel! It's really tough to make a final decision here, but if I'd need to, I'd say Porsche. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
