Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 5-door wagon body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (4 x 4 for the Mazda and front in the case of the Nissan). The first one has a Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 160hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 140hp engine designed by Nissan.

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 that fact doesn't break the tie between the two cars. Furthermore, taking kerb weight as an important factor into account, Mazda 6 offers a considerable difference of 18% 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, all the models observed together. These are the official statistics, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the Nissan badge with 4.3 out of 5. Some independent research have also placed 6 as average reliability-wise, and Primera is more or less at the same level.That apart, owners of different cars powered by the same engine as Mazda 6 rank it on average as 5.0, while the one under the competitor's bonnet gets 4.2 out of 5.

Nissan is undoubtly more agile, reaching 100km/h in 2.4 seconds less than its competitor. In addition to that it accelerates all the way to 200 kilometers per hour, 11km/h more than the other car. When it comes to fuel economy the winner has to be Primera, averaging around 9.1 liters of fuel per 100 kilometers (31 mpg), in combined cycle. We can't ignore that 15% difference compared to Mazda 6.

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, Mazda 6 offers significantly better overall protection, taking the lead here. From there things take a different direction, with Nissan being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! I believe that, when we take all into account, we have only one winner here - the Nissan.
