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 large family car segment and utilize the same 4-door sedan 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 Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 145hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 176hp engine designed by Hyundai.

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 same number of safety stars gained in the process. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, the Korean car offers a marginal difference of 9% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that both brands display similar results in faults and breakdowns, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the Hyundai badge with 4.5 out of 5. Independent research findings rank 6 as average reliability-wise, and i40 is more or less at the same level.Above it all, drivers of cars with the same engine as the Japanese car rank it on average as 5.0, while the one under the competitor's bonnet gets 3.0 out of 5.

Mazda is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 208 kilometers per hour, 5km/h less than the other car. When it comes to fuel economy the winner has to be the Japanese car, averaging around 5.5 liters of fuel per 100 kilometers (51 mpg), in combined cycle. We can't ignore that 24% difference compared to the Korean car.

Mazda 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 Korean car offers slightly better overall protection and takes the lead. From there things take a different direction, with Mazda offering somewhat better performance, just enough to call it quicker. 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 Mazda. 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.
