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. Both the engines are Volkswagen-engineered . The first one has a 8-cylinder, 32-valves 550hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 600hp one.
SafetyThe first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. 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, when it comes to weight, a factor that most people underestimate, Audi Q8 offers a marginal difference of 5% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Audi does have a slight advantage, all the models observed together. These are the official statistics, 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. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. We should definitely mention that owners of cars with the same powertrain as Cayenne rank it on average as 3.0 out of 5, exactly the same as the other one.
Performance & Fuel economyAudi is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. In addition to that it accelerates all the way to 305 kilometers per hour, 19km/h more than the other car. When it comes to fuel economy the winner has to be Cayenne, averaging around 11.3 liters of fuel per 100 kilometers (25 mpg), in combined cycle. We can't ignore that 7% difference compared to Audi Q8.
Verdict
Audi 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, Audi Q8 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Audi offering somewhat better performance, just enough to call it quicker. 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 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.
