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 petrol engine choice they offer. The first one has a Toyota-engineered powertrain under the hood, a 4-cylinder, 16-valves 245hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 211hp 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. That aside, let's consider some other aspects which affect safety. 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. Furthermore, when it comes to weight, a factor that most people underestimate, Lexus IS offers a considerable difference of 11% more metal.

Reliability

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Lexus does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Lexus with an average rating of 5.0, and models under the Infiniti badge with 4.5 out of 5. Some independent research have also placed IS 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 Lexus IS rank it on average as 5.0 out of 5, exactly the same as the other one.

Performance & Fuel economy

Lexus is undoubtly more agile, reaching 100km/h in 1.5 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 230 kilometers per hour, exactly the same as the other car does. When it comes to fuel economy an obvious choice would be Q50, averaging around 4.8 liters of fuel per 100 kilometers (59 mpg), in combined cycle. That's 46% difference compared to Lexus IS!


Verdict

Lexus 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, Lexus IS offers significantly better overall protection, taking the lead here. It all continues in the same direction, with Lexus being considerably quicker, thus putting more smile on driver's face. 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. 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. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser, out of 12.000+ vehicles we currently have in our database.
