Virtual Adviser's™ opinion

Overview

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 rear wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a BMW-engineered powertrain under the hood, a 4-cylinder, 16-valves 143hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Mercedes Benz.

Safety

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Moving further on, let's take a closer look at some additional safety-related facts. 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. On the other hand, when it comes to weight, a factor that most people underestimate, the Japanese car offers a considerable difference of 18% more metal.

Reliability

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Infiniti does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of BMW with an average rating of 4.2, and models under the Infiniti badge with 4.6 out of 5. Some independent research have also placed 3 Series as average reliability-wise, and Q50 is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as the German car rank it on average as 4.3, while the one under the competitor's bonnet gets 4.2 out of 5.

Performance & Fuel economy

Infiniti is a bit more agile, reaching 100km/h in 0.3 seconds less than its competitor. In addition to that it accelerates all the way to 231 kilometers per hour, 19km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 4.4 liters of fuel per 100 kilometers (64 mpg), in combined cycle.

Verdict

Infiniti 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 Japanese car offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Infiniti offering somewhat better performance, just enough to call it quicker. Fuel consumption is more or less the same. I believe that, when we take all into account, we have only one winner here - the Infiniti. 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. 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.
