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 mpv segment and utilize the same 5-door MPV body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Volkswagen-engineered powertrain under the hood, a 4-cylinder, 16-valves 85hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 112hp engine designed by Renault.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the mpv segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, when it comes to weight, a factor that most people underestimate, 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, all the models observed together. That's the official data, 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 Altea as average reliability-wise, and Grand Scenic is more or less at the same level.Above it all, drivers of cars with the same engine as the Spanish car rank it on average as 3.6, while the one under the competitor's bonnet gets 3.9 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 1.9 seconds less than its competitor. In addition to that it accelerates all the way to 185 kilometers per hour, 16km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 7.4 liters of fuel per 100 kilometers (38 mpg), in combined cycle.

Renault 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 French car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Renault being considerably quicker, thus putting more smile on driver's face. Fuel consumption is more or less the same. It's not difficult to say then that if I'd need to make a choice, it would definitely be the Renault. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
