Virtual Adviser's™ opinion
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 wagon 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 Renault-engineered powertrain under the hood, a 4-cylinder, 8-valves 116hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 121hp engine designed by Mazda.
SafetyThe 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. That aside, let's consider some other aspects which affect safety. 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, if we'd like to consider vehicle mass in this context too, which we definitely should, Mazda 6 offers a marginal difference of 1% more metal.
ReliabilityManufacturers have been building their reliability reputation for decades now and, generally speaking, it appears 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 Nissan with an average rating of 4.3, and models under the Mazda badge with 4.4 out of 5. Independent research findings rank Primera 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 Primera rank it on average as 4.9, while the one under the competitor's bonnet gets 4.4 out of 5.
Performance & Fuel economyBoth of the cars accelerate exactly the same, so we couldn't put one above the other. Car No. 1 reaches top speed of 194 kilometers per hour, 1km/h more than the other car. When it comes to fuel economy the winner has to be Primera, averaging around 5.7 liters of fuel per 100 kilometers (50 mpg), in combined cycle. We can't ignore that 16% difference compared to Mazda 6.
Verdict
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, Mazda 6 offers slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Primera , on the other hand, consumps significantly less fuel, and that's a big plus. It's not difficult to say then that if I'd need to make a choice, it would definitely be the Nissan. 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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, among thousands of similar, yet so different vehicles.
