Virtual Adviser's™ opinion
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 Hyundai-engineered powertrain under the hood, a 4-cylinder, 16-valves 128hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 110hp engine designed by Volkswagen.Safety
The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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 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 Korean car offers a marginal difference of 9% more metal.Reliability
Reliability is not the best thing to consider on the make level, but it is worth mentioning that Hyundai does have a slight advantage, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Hyundai with an average rating of 4.6, and models under the Seat badge with 4.4 out of 5. Independent research findings rank i30 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 Korean car rank it on average as 4.3 out of 5, exactly the same as the other one.Performance & Fuel economy
Seat is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 200 kilometers per hour, 12km/h more than the other car. 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.
Hyundai 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 Korean car offers slightly better overall protection and takes the lead. From there things take a different direction, with Seat offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! It's really tough to make a final decision here, but if I'd need to, I'd say Seat. 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.
