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 5-door hatchback body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Toyota-engineered powertrain under the hood, a 4-cylinder, 16-valves 116hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 121hp engine designed by Mazda.

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 Toyota being a slightly better choice apparently. 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, still it doesn't help us solve our dilemma, does it? On the other hand, taking kerb weight as an important factor into account, Mazda 6 offers a marginal difference of 3% 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, at least on all of the models level. That's the official data, while our visitors describe reliability of Toyota with an average rating of 4.6, and models under the Mazda badge with 4.5 out of 5. Some independent research have also placed Avensis as average reliability-wise, and 6 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Avensis rank it on average as 4.5, while the one under the competitor's bonnet gets 4.4 out of 5.

Mazda is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 196 kilometers per hour, 1km/h more than the other car. When it comes to fuel economy the winner has to be Avensis, averaging around 5.8 liters of fuel per 100 kilometers (49 mpg), in combined cycle. We can't ignore that 12% difference compared to Mazda 6.

Toyota 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, Avensis 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. It does come at a cost though, and that's the fuel consumption... It's not difficult to say then that if I'd need to make a choice, it would definitely be the Toyota. 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.
