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 Renault-engineered powertrain under the hood, a 4-cylinder, 8-valves 130hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 136hp engine designed by Peugeot.

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. 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, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, 407 offers a considerable difference of 13% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that both brands display similar results in faults and breakdowns, 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 Peugeot badge with 4.3 out of 5. Independent research findings rank Laguna as average reliability-wise, and 407 is more or less at the same level.That apart, owners of different cars powered by the same engine as Laguna rank it on average as 4.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Peugeot 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 203 kilometers per hour, 2km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6 liters of fuel per 100 kilometers (47 mpg), in combined cycle.

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. It all continues in the same direction, with Peugeot being considerably quicker, thus putting more smile on driver's face. Fuel consumption is more or less the same. It's not difficult to say then that if I'd need to make a choice, it would definitely be the Peugeot. 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
