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 diesel engine choice they offer. The first one has a Ford-engineered powertrain under the hood, a 6-cylinder, 24-valves 204hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 178hp 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. 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, 407 offers a marginal difference of 6% 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, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Peugeot with an average rating of 4.3, and models under the Renault badge with 4.1 out of 5. Independent research findings rank 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 4.5 out of 5.

Peugeot is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. In addition to that it accelerates all the way to 228 kilometers per hour, 13km/h more than the other car. When it comes to fuel economy the winner has to be Laguna, averaging around 6.6 liters of fuel per 100 kilometers (43 mpg), in combined cycle. We can't ignore that 29% difference compared to 407.

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, 407 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Peugeot offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the Renault. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process.
