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 hybrid engine choice they offer. The first one has a Nissan-engineered powertrain under the hood, a 6-cylinder, 24-valves 364hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 223hp engine designed by Toyota.

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 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 it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, Q50 offers a marginal difference of 8% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Lexus does have a slight advantage, all the models observed together. That's the official data, while our visitors describe reliability of Infiniti with an average rating of 4.6, and models under the Lexus badge with 4.9 out of 5. The same official information place Q50 as average reliability-wise, and IS is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as Q50 rank it on average as 3.0, while the one under the competitor's bonnet gets 5.0 out of 5.

Infiniti is way more agile, reaching 100km/h in 3.2 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 50km/h more than the other car. When it comes to fuel economy the winner has to be Lexus IS, averaging around 4.3 liters of fuel per 100 kilometers (66 mpg), in combined cycle. We can't ignore that 44% difference compared to Q50.

Lexus is apparently more reliable, not too much, but just enough. 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 outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for 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.
