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 102hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 68hp engine designed by Suzuki.

The fact that the Daihatsu got tested by the European New Car Assessment Programme (Euro NCAP), while the other contender didn't, isn't really an advantage, taken the poor 3-star rating it received. 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. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Sirion offers a marginal difference of 8% 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, when all the models are taken into account. That's the official data, while our visitors describe reliability of Daihatsu with an average rating of 4.2, and models under the Suzuki badge with 4.6 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. Above it all, drivers of cars with the same engine as Sirion rank it on average as 3.0, while the one under the competitor's bonnet gets 3.3 out of 5.

Daihatsu is way more agile, reaching 100km/h in 3.4 seconds less than its competitor. In addition to that it accelerates all the way to 180 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 5.8 liters of fuel per 100 kilometers (49 mpg), in combined cycle.

Suzuki 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, Sirion offers much better overall protection, which launches it ahead of the other contender. It all continues in the same direction, with Daihatsu 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 Daihatsu. 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. 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™, among thousands of similar, yet so different vehicles.
