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 mpv segment and utilize the same 5-door MPV 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 Mazda-engineered powertrain under the hood, a 4-cylinder, 16-valves 100hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 150hp engine designed by Renault.

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 Renault displaying significantly better structural stability. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the mpv 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 French car offers a considerable difference of 11% 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. That's the official data, while our visitors describe reliability of Mazda with an average rating of 4.4, and models under the Renault badge with 4.1 out of 5. Some independent research have also placed Premacy as average reliability-wise, and Grand Scenic is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the Japanese car rank it on average as 4.3, while the one under the competitor's bonnet gets 4.6 out of 5.

Renault is undoubtly more agile, reaching 100km/h in 1.8 seconds less than its competitor. In addition to that it accelerates all the way to 204 kilometers per hour, 34km/h more than the other car. When it comes to fuel economy the winner has to be the French car, averaging around 5.8 liters of fuel per 100 kilometers (49 mpg), in combined cycle. We can't ignore that 10% difference compared to the Japanese 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 French car beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Renault being considerably quicker, thus putting more smile on driver's face. 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 Renault. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process. I suggest you spend two more minutes in order to find out which car, based on your needs and budget, would be picked by the virtual adviser™, among thousands of similar, yet so different vehicles.
