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 Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 200hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 177hp engine designed by Volkswagen.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), 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, the French car offers a marginal difference of 8% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Peugeot as a brand displays somewhat better results, at least on all of the models level. That's the official data, while our visitors describe reliability of Peugeot with an average rating of 4.3, and models under the Audi badge with 4.2 out of 5. Some independent research have also placed 508 as average reliability-wise, and A4 is more or less at the same level.Above it all, drivers of cars with the same engine as the French car rank it on average as 4.0, while the one under the competitor's bonnet gets 3.9 out of 5.

Peugeot is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 232 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 4.8 liters of fuel per 100 kilometers (59 mpg), in combined cycle. We can't ignore that 23% difference compared to the French car.

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, the French car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Peugeot outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. 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.
