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 luxury car segment and utilize the same 5-door hatchback 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 Volkswagen-engineered powertrain under the hood, a 8-cylinder, 32-valves 422hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 347hp engine designed by Audi.

The fact that the Audi got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, Panamera offers a marginal difference of 2% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Audi does have a slight advantage, at least on all of the models level. 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. Above it all, drivers of cars with the same engine as Panamera rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Porsche is a bit more agile, reaching 100km/h in 0.6 seconds less than its competitor. In addition to that it accelerates all the way to 285 kilometers per hour, 35km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6.7 liters of fuel per 100 kilometers (42 mpg), in combined cycle.

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 A7 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 offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but Audi. 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.
