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 6-cylinder, 24-valves 210hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 207hp engine designed by Renault.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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 large family car segment, which is generally a good thing safety-wise, but that fact doesn't break the tie between the two cars. Furthermore, when it comes to weight, a factor that most people underestimate, 407 offers a considerable difference of 21% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, at least on all of the models level. 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 407 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 407 rank it on average as 4.0, while the one under the competitor's bonnet gets 3.7 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 1.3 seconds less than its competitor. In addition to that it accelerates all the way to 232 kilometers per hour, 3km/h more than the other car. When it comes to fuel economy the winner has to be Laguna, averaging around 8.6 liters of fuel per 100 kilometers (33 mpg), in combined cycle. We can't ignore that 15% difference compared to 407.

Peugeot 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, 407 offers significantly better overall protection, taking the lead here. From there things take a different direction, with Renault 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 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, out of 12.000+ vehicles we currently have in our database.
