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 MPV body style within the same 'MPV' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Mercedes Benz and front in the case of the Seat). The first one has a Mercedes Benz-engineered powertrain under the hood, a 6-cylinder, 24-valves 272hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 160hp engine designed by Volkswagen.

The fact that the Seat 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. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the mpv segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, the German car offers a self-explainatory difference of 51% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Seat does have a slight advantage, all the models observed together. These are the official statistics, while our visitors describe reliability of Mercedes Benz, as well as Seat, with the same average rating of 4.4 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 the German car rank it on average as 5.0, while the one under the competitor's bonnet gets 4.2 out of 5.

Mercedes Benz 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 230 kilometers per hour, 20km/h more than the other car. When it comes to fuel economy an obvious choice would be the Spanish car, averaging around 7.1 liters of fuel per 100 kilometers (40 mpg), in combined cycle. That's 63% difference compared to the German car!

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, the Spanish car offers significantly better overall protection, taking the lead here. From there things take a different 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... All together, there's not much more to say, in this case I wouldn't even consider anything but Seat. 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.
