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 diesel engine choice they offer. The first one has a Isuzu-engineered powertrain under the hood, a 4-cylinder, 16-valves 80hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 121hp engine designed by VM Motori.

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? On the other hand, taking kerb weight as an important factor into account, the American car offers a marginal difference of 4% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Chevrolet does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Opel, as well as Chevrolet, with the same average rating of 4.2 out of 5. Some independent research have also placed Astra as average reliability-wise, and Lacetti is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 4.1, while the one under the competitor's bonnet gets 4.9 out of 5.

Chevrolet is way more agile, reaching 100km/h in 5.6 seconds less than its competitor. In addition to that it accelerates all the way to 186 kilometers per hour, 18km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5 liters of fuel per 100 kilometers (57 mpg), in combined cycle. We can't ignore that 20% difference compared to the American 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. From there things take a different direction, with Chevrolet 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. 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™, out of 12.000+ vehicles we currently have in our database.
