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 suv segment and utilize the same 5-door suv body style and the front wheel drive system, it all comes up to the specific hybrid engine choice they offer. The first one has a Renault-engineered powertrain under the hood, a 4-cylinder, 16-valves 158hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 195hp engine designed by Peugeot.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the suv segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, C5 Aircross offers a considerable difference of 26% more metal.

I don't like generalizing things when it comes to reliability, although it does seem 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 with an average rating of 4.2, and models under the Citroen badge with 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. Above it all, drivers of cars with the same engine as Symbioz rank it on average as 3.0 out of 5, exactly the same as the other one.

Citroen is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 220 kilometers per hour, 40km/h more than the other car. When it comes to fuel economy the winner has to be C5 Aircross, averaging around 2.6 liters of fuel per 100 kilometers (109 mpg), in combined cycle. We can't ignore that 73% difference compared to Symbioz.

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, C5 Aircross offers significantly better overall protection, taking the lead here. It all continues in the same 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! All together, there's not much more to say, in this case I wouldn't even consider anything but Citroen. 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.
