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 Peugeot-engineered powertrain under the hood, a 4-cylinder, 8-valves 112hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 90hp engine designed by Renault.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, 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 mpv segment, which is generally a 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 French car offers a considerable difference of 15% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Nissan does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Citroen with an average rating of 4.0, and models under the Nissan badge with 4.3 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. Above it all, drivers of cars with the same engine as the French car rank it on average as 3.8, while the one under the competitor's bonnet gets 4.5 out of 5.

Both of the cars accelerate exactly the same, so we couldn't put one above the other. Car No. 1 reaches top speed of 179 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy the winner has to be the Japanese 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 French car.

Nissan 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 Citroen offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say Nissan. 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.
