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 Suzuki-engineered powertrain under the hood, a 3-cylinder, 6-valves 53hp unit, while the other one gets its power and torque from a 3-cylinder, 12-valves 55hp engine designed by Daihatsu.

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. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the city car segment, which is generally not a very good thing safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, Sirion offers a marginal difference of 8% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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 Suzuki with an average rating of 4.5, and models under the Daihatsu 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. We should definitely mention that owners of cars with the same powertrain as Swift rank it on average as 5.0, while the one under the competitor's bonnet gets 3.5 out of 5.

Daihatsu is a bit more agile, reaching 100km/h in 0.5 seconds less than its competitor. In addition to that it accelerates all the way to 145 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 5.5 liters of fuel per 100 kilometers (51 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 offering somewhat better performance, just enough to call it quicker. Fuel consumption is more or less the same. I believe that, when we take all into account, we have only one winner here - the 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.
