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 large family car segment and utilize the same 5-door wagon body style and the front wheel drive system, it all comes up to the specific petrol engine choice they offer. The first one has a Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 117hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 120hp 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 Renault displaying significantly better structural stability. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car 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, 406 offers a marginal difference of 1% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, all the models observed together. These are the results of an independent reasearch, while our visitors describe reliability of Peugeot with an average rating of 4.3, and models under the Renault badge with 4.2 out of 5. Some independent research have also placed 406 as average reliability-wise, and Laguna is more or less at the same level.That apart, owners of different cars powered by the same engine as 406 rank it on average as 4.0, while the one under the competitor's bonnet gets 4.7 out of 5.

Renault 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 198 kilometers per hour, 5km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 7.8 liters of fuel per 100 kilometers (36 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, Laguna offers much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, 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. 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.
