Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. 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 (front for the Seat and 4 x 4 in the case of the Audi).

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. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 18% 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 Seat with an average rating of 4.5, and models under the Audi badge with 4.2 out of 5. The same official information place Leon as average reliability-wise, and A3 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as these two vehicles rank it on average as 4.7 out of 5.

Audi is a bit more agile, reaching 100km/h in 0.7 seconds less than its competitor. In addition to that it accelerates all the way to 230 kilometers per hour, 2km/h more than the other car. When it comes to fuel economy the winner has to be the Spanish car, averaging around 4.2 liters of fuel per 100 kilometers (67 mpg), in combined cycle. We can't ignore that 19% difference compared to the German car.

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 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... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
