Virtual Adviser's™ opinion

Overview

Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by hybrid 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 (4 x 4 for the Infiniti and rear in the case of the Lexus). 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.

Safety

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, still it doesn't help us solve our dilemma, does it? Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, Q50 offers a considerable difference of 13% more metal.

Reliability

I don't like generalizing things when it comes to reliability, although it does seem that Lexus does have a slight advantage, all the models observed together. These are the results of an independent reasearch, 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. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models 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.

Performance & Fuel economy

Infiniti is undoubtly more agile, reaching 100km/h in 2.9 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 an obvious choice would be Lexus IS, averaging around 4.6 liters of fuel per 100 kilometers (61 mpg), in combined cycle. That's 43% difference compared to Q50!


Verdict

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 significantly better overall protection, taking the lead here. It all continues in the same direction, with Infiniti being considerably quicker, thus putting more smile on driver's face. It does come at a cost though, and that's the fuel consumption... It's not difficult to say then that if I'd need to make a choice, it would definitely be the Lexus. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help. 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.
