Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 5-door hatchback body style within the same 'Luxury car' segment, the only major difference here really is their wheel drive configuration (rear for the Porsche and 4 x 4 in the case of the Audi). The first one has a Porsche-engineered powertrain under the hood, a 6-cylinder, 24-valves 310hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 450hp engine designed by Volkswagen.

Unfortunatelly, 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. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, Audi A7 offers a marginal difference of 9% more metal.

I don't like generalizing things when it comes to reliability, although it does seem 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. That apart, owners of different cars powered by the same engine as Panamera rank it on average as 3.0 out of 5, exactly the same as the other one.

Audi is undoubtly more agile, reaching 100km/h in 1.7 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 250 kilometers per hour, 9km/h less than the other car. When it comes to fuel economy the winner has to be Panamera, averaging around 8.4 liters of fuel per 100 kilometers (34 mpg), in combined cycle. We can't ignore that 11% difference compared to Audi A7.

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 A7 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Audi being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say Porsche. 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.
