Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 4-door sedan body style within the same 'Large family car' segment, the only major difference here really is their wheel drive configuration (front for the Honda and rear in the case of the Infiniti). The first one has a Honda-engineered powertrain under the hood, a 4-cylinder, 16-valves 150hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 170hp engine designed by Mercedes Benz.

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 that fact doesn't break the tie between the two cars. On the other hand, if we'd like to consider vehicle mass in this context too, which we definitely should, Q50 offers a marginal difference of 9% more metal.

I don't like generalizing things when it comes to reliability, although it does seem that Honda as a brand displays somewhat better results, at least on all of the models level. These are the results of an independent reasearch, while our visitors describe reliability of Honda with an average rating of 4.7, and models under the Infiniti badge with 4.5 out of 5. The same official information place Accord as average reliability-wise, and Q50 is more or less at the same level.Above it all, drivers of cars with the same engine as Accord rank it on average as 4.9, while the one under the competitor's bonnet gets 4.5 out of 5.

Infiniti is a bit more agile, reaching 100km/h in 0.7 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 the winner has to be Q50, averaging around 4.4 liters of fuel per 100 kilometers (64 mpg), in combined cycle. We can't ignore that 20% difference compared to Accord.

Honda 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, Q50 offers slightly better overall protection and takes the lead. It all continues in the same direction, with Infiniti offering somewhat better performance, just enough to call it quicker. 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 Infiniti. 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.
