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 diesel engine choice they offer. The first one has a Isuzu-engineered powertrain under the hood, a 6-cylinder, 24-valves 177hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Peugeot.

The fact that the Renault got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. Moving further on, let's take a closer look at some additional safety-related facts. 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. Furthermore, when it comes to weight, a factor that most people underestimate, Grand Espace offers a marginal difference of 5% 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 Renault with an average rating of 4.2, and models under the Citroen badge with 4.0 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. We should definitely mention that owners of cars with the same powertrain as Grand Espace rank it on average as 4.8, while the one under the competitor's bonnet gets 4.3 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 1 seconds less than its competitor. In addition to that it accelerates all the way to 204 kilometers per hour, 4km/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, Grand Espace beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Renault outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... All together, there's not much more to say, in this case I wouldn't even consider anything but Renault. 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.
