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 Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 130hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp 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. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the mpv segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, taking kerb weight as an important factor into account, Grand Espace offers a marginal difference of 3% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Renault does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Renault, as well as Citroen, with the same average rating of 4.1 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 3.0, while the one under the competitor's bonnet gets 4.2 out of 5.

Citroen is way more agile, reaching 100km/h in 3 seconds less than its competitor. In addition to that it accelerates all the way to 194 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy the winner has to be Citroen C8, averaging around 5.9 liters of fuel per 100 kilometers (48 mpg), in combined cycle. We can't ignore that 25% difference compared to Grand Espace.

Citroen 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. From there things take a different direction, with Citroen outracing its opponent in any situation possible, making it better choice for boy racers. To make things even better, it consumps less fuel! At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
