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 3-cylinder, 12-valves 69hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 85hp engine designed by General Motors.

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 Daihatsu displaying significantly better structural stability. Moving further on, let's take a closer look at some additional safety-related facts. 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, when it comes to weight, a factor that most people underestimate, the American car offers a considerable difference of 16% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Daihatsu does have a slight advantage, at least on all of the models level. These are the official statistics, while our visitors describe reliability of Daihatsu with an average rating of 4.1, and models under the Chevrolet badge with 4.2 out of 5. The same official information place Sirion as average reliability-wise, and Aveo 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 4.5 out of 5, exactly the same as the other one.

Chevrolet is undoubtly more agile, reaching 100km/h in 1.1 seconds less than its competitor. In addition to that it accelerates all the way to 170 kilometers per hour, 10km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 5.3 liters of fuel per 100 kilometers (54 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 Japanese car offers significantly better overall protection, taking the lead here. From there things take a different direction, with Chevrolet being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the Daihatsu. 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.
