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 micro car segment and utilize the same 3-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 General Motors-engineered powertrain under the hood, a 3-cylinder, 12-valves 90hp unit, while the other one gets its power and torque from a 3-cylinder, 12-valves 102hp engine designed by BMW.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Mini being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the micro car segment, which is generally a misfortune 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 British car offers a marginal difference of 2% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that both brands display similar results in faults and breakdowns, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Mini badge with 4.1 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as the German car rank it on average as 3.0 out of 5, exactly the same as the other one.

Mini is undoubtly more agile, reaching 100km/h in 2 seconds less than its competitor. In addition to that it accelerates all the way to 195 kilometers per hour, 15km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.4 liters of fuel per 100 kilometers (64 mpg), in combined cycle.

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 British car offers much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Mini 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 Mini. 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. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among thousands of similar, yet so different vehicles.
