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 city 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 Renault-engineered powertrain under the hood, a 4-cylinder, 8-valves 95hp unit, while the other one gets its power and torque from a 3-cylinder, 12-valves 90hp engine designed by Volkswagen.

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 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 city car segment, which is generally not a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the Romanian car offers a marginal difference of 7% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, all the models observed together. That's the official data, while our visitors describe reliability of Dacia with an average rating of 4.1, and models under the Seat badge with 4.4 out of 5. The same official information place Sandero as average reliability-wise, and Ibiza is more or less at the same level.Above it all, drivers of cars with the same engine as the Romanian car rank it on average as 3.0, while the one under the competitor's bonnet gets 4.2 out of 5.

Seat is undoubtly more agile, reaching 100km/h in 1.4 seconds less than its competitor. In addition to that it accelerates all the way to 182 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be the Spanish car, averaging around 3.6 liters of fuel per 100 kilometers (78 mpg), in combined cycle. We can't ignore that 33% difference compared to the Romanian 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 Spanish car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Seat being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but 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.
