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 5-door wagon 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 Opel-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 114hp engine designed by Chevrolet.

The fact that the Opel got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, puts it sky-high safety-wise, in my eyes at least. 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. Furthermore, taking kerb weight as an important factor into account, the German car offers a considerable difference of 14% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Chevrolet does have a slight advantage, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Opel, as well as Chevrolet, with the same average rating of 4.2 out of 5. Independent research findings rank Astra as average reliability-wise, and Lacetti is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.3, while the one under the competitor's bonnet gets 4.8 out of 5.

Opel is way more agile, reaching 100km/h in 3 seconds less than its competitor. In addition to that it accelerates all the way to 230 kilometers per hour, 43km/h more than the other car. When it comes to fuel economy the winner has to be the American car, averaging around 7.8 liters of fuel per 100 kilometers (36 mpg), in combined cycle. We can't ignore that 24% difference compared to the German car.

Chevrolet 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 beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Opel 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... All together, there's not much more to say, in this case I wouldn't even consider anything but Opel. 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.
