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 small family car segment and utilize the same 5-door hatchback 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 Honda-engineered powertrain under the hood, a 4-cylinder, 16-valves 120hp unit, while the other one gets its power and torque from a 4-cylinder, 8-valves 110hp engine designed by Renault.

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 small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, Q30 offers a marginal difference of 4% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Honda as a brand displays somewhat better results, all the models observed together. 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. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. That apart, owners of different cars powered by the same engine as Civic rank it on average as 4.9, while the one under the competitor's bonnet gets 4.2 out of 5.

Honda is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. In addition to that it accelerates all the way to 207 kilometers per hour, 17km/h more than the other car. When it comes to fuel economy things look pretty much the same for both cars, averaging around 3.8 liters of fuel per 100 kilometers (74 mpg), in combined cycle.

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, Q30 offers slightly better overall protection and takes the lead. From there things take a different direction, with Honda being considerably quicker, thus putting more smile on driver's face. To make things even better, it consumps less fuel! It's not difficult to say then that if I'd need to make a choice, it would definitely be the Honda. 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.
