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 small family car segment and utilize the same 2-door cabriolet 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.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Renault being a slightly better choice apparently. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, 307 offers a considerable difference of 11% 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, at least on all of the models level. 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. Some independent research have also placed Megane as average reliability-wise, and 307 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Megane rank it on average as 4.0, while the one under the competitor's bonnet gets 4.3 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 203 kilometers per hour, 5km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.9 liters of fuel per 100 kilometers (48 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 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 offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - 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. 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™, among thousands of similar, yet so different vehicles.
