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 140hp engine designed by Nissan.

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 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, if we'd like to consider vehicle mass in this context too, which we definitely should, Primera offers a marginal difference of 5% 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, at least on all of the models level. 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. The same official information place 6 as average reliability-wise, and Primera is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Mazda 6 rank it on average as 4.2 out of 5, exactly the same as the other one.

Nissan is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 200 kilometers per hour, 8km/h less than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 8.6 liters of fuel per 100 kilometers (33 mpg), in combined cycle.

Nissan 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, Primera offers slightly better overall protection and takes the lead. It all continues in the same direction, with Nissan offering somewhat better performance, just enough to call it quicker. It does come at a cost though, and that's the fuel consumption... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
