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 city 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 Daihatsu-engineered powertrain under the hood, a 4-cylinder, 16-valves 91hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 80hp engine designed by Opel.

The first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, 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 city car segment, which is generally not a very good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a marginal difference of 2% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Daihatsu as a brand displays somewhat better results, all the models observed together. These are the official statistics, while our visitors describe reliability of Daihatsu, as well as Opel, with the same average rating of 4.2 out of 5. Independent research findings rank Sirion as average reliability-wise, and Corsa is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Japanese car rank it on average as 5.0, while the one under the competitor's bonnet gets 4.7 out of 5.

Daihatsu is undoubtly more agile, reaching 100km/h in 1.7 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 170 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy things look pretty much the same for both cars, averaging around 6 liters of fuel per 100 kilometers (47 mpg), in combined cycle.

Daihatsu 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 offers slightly better overall protection and takes the lead. From there things take a different direction, with Daihatsu being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! It's not difficult to say then that if I'd need to make a choice, it would definitely be the Daihatsu. 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.
