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 mpv segment and utilize the same 5-door MPV 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 140hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 147hp engine designed by Chrysler.

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 Opel showing an incomparably higher level of safety offered. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the mpv segment, which is generally a good thing 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 considerable difference of 29% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Opel as a brand displays somewhat better results, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Chrysler badge with 4.4 out of 5. Independent research findings rank Zafira as average reliability-wise, and Voyager 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 4.5, while the one under the competitor's bonnet gets 4.0 out of 5.

Opel is a bit more agile, reaching 100km/h in 0.9 seconds less than its competitor. In addition to that it accelerates all the way to 197 kilometers per hour, 14km/h more than the other car. When it comes to fuel economy an obvious choice would be the German car, averaging around 7.6 liters of fuel per 100 kilometers (37 mpg), in combined cycle. That's 33% difference compared to the American car!

Opel 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. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Opel. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
