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 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 petrol engine choice they offer. The first one has a Mercedes Benz-engineered powertrain under the hood, a 8-cylinder, 32-valves 639hp unit, while the other one gets its power and torque from a 8-cylinder, 32-valves 550hp engine designed by Volkswagen.
SafetyUnfortunatelly, 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. 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, but that fact doesn't break the tie between the two cars. Furthermore, when it comes to weight, a factor that most people underestimate, AMG GT 4-Door Coupé offers a marginal difference of 6% more metal.
ReliabilityI 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. These are the results of an independent reasearch, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Porsche badge with 3.7 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 AMG GT 4-Door Coupé rank it on average as 3.0 out of 5, exactly the same as the other one.
Performance & Fuel economyMercedes Benz 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 315 kilometers per hour, 9km/h more than the other car. When it comes to fuel economy the winner has to be Panamera, averaging around 9.4 liters of fuel per 100 kilometers (30 mpg), in combined cycle. We can't ignore that 20% difference compared to AMG GT 4-Door Coupé.
Verdict
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, AMG GT 4-Door Coupé offers slightly better overall protection and takes the lead. It all continues in the same direction, with Mercedes Benz 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. 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.
