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 hatchback 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. 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, still it doesn't help us solve our dilemma, does it? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 12% 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, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Opel, as well as Chevrolet, with the same average rating of 4.2 out of 5. The same official information place Astra as average reliability-wise, and Lacetti is more or less at the same level.We should definitely mention that owners of cars with the same powertrain 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 undoubtly more agile, reaching 100km/h in 2.8 seconds less than its competitor. In addition to that it accelerates all the way to 232 kilometers per hour, 45km/h more than the other car. When it comes to fuel economy an obvious choice would be the American car, averaging around 7.1 liters of fuel per 100 kilometers (40 mpg), in combined cycle. That's 32% 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 being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the 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.
