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 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Audi and front in the case of the Seat). The first one has a Audi-engineered powertrain under the hood, a 6-cylinder, 24-valves 240hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Volkswagen.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Audi being a slightly better choice apparently. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a considerable difference of 16% more metal.

I don't like generalizing things when it comes to reliability, although it does seem 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 Audi with an average rating of 4.2, and models under the Seat badge with 4.4 out of 5. Some independent research have also placed A4 as average reliability-wise, and Exeo is more or less at the same level.Above it all, drivers of cars with the same engine 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.

Audi is undoubtly more agile, reaching 100km/h in 2.3 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 21km/h more than the other car. When it comes to fuel economy the winner has to be the Spanish car, averaging around 5.8 liters of fuel per 100 kilometers (49 mpg), in combined cycle. We can't ignore that 14% difference compared to the German car.

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, the German car beats the other contender by far, making it the best choice without even considering other things. 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... No mistake, whatever you decide here, but I'd still go for the Audi. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
