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 small family car segment and utilize the same 5-door hatchback body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 16-valves 105hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 129hp engine designed by Renault.

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 Seat being a slightly better choice apparently. 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 it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, the French car offers a considerable difference of 12% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Renault does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Seat with an average rating of 4.4, and models under the Renault badge with 4.1 out of 5. The same official information place Leon as average reliability-wise, and Megane is more or less at the same level.That apart, owners of different cars powered by the same engine as the Spanish car rank it on average as 4.5, while the one under the competitor's bonnet gets 4.6 out of 5.

Renault 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 200 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy the winner has to be the Spanish car, averaging around 3.2 liters of fuel per 100 kilometers (88 mpg), in combined cycle. We can't ignore that 28% difference compared to the French 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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Renault offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the 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.
