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 diesel engine choice they offer. The first one has a FIAT-engineered powertrain under the hood, a 4-cylinder, 16-valves 160hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 163hp engine designed by General Motors.

A starting point here would be to take a look at the results from European New Car Assessment Programme (Euro NCAP) tests which were performed on both of the cars, 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 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.

I don't like generalizing things when it comes to reliability, although it does seem that Chevrolet does have a slight advantage, all the models observed together. 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. Independent research findings rank Astra as average reliability-wise, and Cruze 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 4.8, while the one under the competitor's bonnet gets 5.0 out of 5.

Chevrolet is a bit more agile, reaching 100km/h in 0.5 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 205 kilometers per hour, 10km/h less than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 4.5 liters of fuel per 100 kilometers (63 mpg), in combined cycle. We can't ignore that 24% 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 American car offers slightly better overall protection and takes the lead. It all continues in the same direction, with Chevrolet 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 Opel. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
