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 173hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 177hp engine designed by VM Motori.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Renault being a slightly better choice apparently. 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, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, the Italian car offers a considerable difference of 16% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Renault does have a slight advantage, when all the models are taken into account. These are the results of an independent reasearch, while our visitors describe reliability of Renault with an average rating of 4.2, and models under the Lancia badge with 4.3 out of 5. The same official information place Grand Espace as average reliability-wise, and Voyager is more or less at the same level.That apart, owners of different cars powered by the same engine as the French car rank it on average as 4.8, while the one under the competitor's bonnet gets 3.7 out of 5.

Renault is a bit more agile, reaching 100km/h in 0.4 seconds less than its competitor. In addition to that it accelerates all the way to 198 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 7.2 liters of fuel per 100 kilometers (39 mpg), in combined cycle. We can't ignore that 10% difference compared to the Italian car.

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 this case though, it seems that both cars show similar levels of passenger protection all together, so that won't break a tie. But one thing that actually could is the performance, with Renault being considerably quicker, thus putting more smile on driver's face. 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 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among thousands of similar, yet so different vehicles.
