Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 3-door hatchback body style within the same 'Small family car' segment, the only major difference here really is their wheel drive configuration (rear for the BMW and front in the case of the Seat). The first one has a BMW-engineered powertrain under the hood, a 3-cylinder, 12-valves 116hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 110hp engine designed by Volkswagen.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 14% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Seat does have a slight advantage, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of BMW with an average rating of 4.2, and models under the Seat badge with 4.4 out of 5. Independent research findings rank 1 Series as average reliability-wise, and Leon is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.5, while the one under the competitor's bonnet gets 4.3 out of 5.

BMW is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 200 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 3.5 liters of fuel per 100 kilometers (82 mpg), in combined cycle.

Seat 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 German car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with BMW offering somewhat better performance, just enough to call it quicker. 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 BMW. 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.
