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 petrol engine choice they offer. The first one has a Peugeot-engineered powertrain under the hood, a 4-cylinder, 16-valves 136hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Opel.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Opel being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, the German car offers a marginal difference of 5% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Peugeot does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Peugeot with an average rating of 4.3, and models under the Opel badge with 4.2 out of 5. The same official information place 307 as average reliability-wise, and Astra 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 4.2, while the one under the competitor's bonnet gets 3.0 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.8 seconds less than its competitor. In addition to that it accelerates all the way to 224 kilometers per hour, 17km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 8.2 liters of fuel per 100 kilometers (34 mpg), in combined cycle. We can't ignore that 12% difference compared to the German 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 German car offers much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Opel offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say Peugeot. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
